NOTE: The term, Electric Vehicle (EV), is used in this Guide to refer to either a vehicle that plugs into an electric power source to charge and store electric energy in a vehicle battery, or to a Fuel Cell Electric Vehicle. For those that plug in, the term includes both plug-in hybrid EVs (PHEV), and battery EV (BEV). The term does not include conventional hybrids, as they do not plug into an electric power source.

! IMPORTANT: To determine which EVs receive support, visit the EV Make/Model Support Reference The GO Plan is required.

Finding and filtering EVs: powertrain and fuel type automatic groups

Starting in Fleet Management Application version 8.0, there are automatically populated built-in groups that allow you to quickly find and filter on EVs in features, reports, and exception rules.

NOTE: For a vehicle’s electric powertrain to be detected, the EV must be supported, and, in the case of a BEV or PHEV, it must have charged at least once.

Found under the Asset Information group, the Powertrain and Fuel Type group automatically classifies electric vehicles (EV) based on their unique powertrain types:

  1. Electric or Hybrid Plug-in: Contains all detected Battery Electric Vehicle (BEV) and detected Plug-in Hybrid (PHEV)
  2. Battery Electric Vehicle (under Electric or Hybrid Plug-in): Contains all detected fully electric Battery Electric Vehicle (BEVs)
  3. Plug-in Hybrid Electric Vehicle (under Electric or Hybrid Plug-in): Contains all detected Plug-in Hybrid (PHEV)
  4. Fuel Cell Electric Vehicle: Contains all detected Fuel Cell Electric Vehicle (FCEV)

Changing automatic classifications

Assets can be manually added or removed from the groups if they are not properly displayed in their respective group.

  1. If an asset is manually assigned to any of these groups, that asset will be tagged under the Manually Classified Powertrain group.
  2. Once an asset is manually classified, the Manually Classified Powertrain group must be removed in order for the asset to get automatically classified again.
  3. If the Manually Classified Powertrain group is removed to re-enable automatic classification, it is recommended that any existing powertrain or fuel type group for the asset is removed at the same time. An asset can be part of multiple groups if it is manually classified. However, in an automatic classification scenario, the asset may be only part of one built-in group, unless the asset is a Plug-in Hybrid vehicle.

EV exception rules

NOTE: For more on Exceptions, see Groups & Rules in the Product Guide.

Built-in exception rules

EV Low Charge

document Image

Get notified when an EV becomes at risk of not having sufficient charge to complete routes without stopping to charge, which is a high productivity loss. This rule will trigger when the electric vehicle (EV) battery charge % (State of Charge) drops below the configured value.

Important information and tips:

    1. The specified Battery charge looks at the Engine Measurement Generic state of charge.
    2. Setting this rule to On via the built-in rule will enable it for all vehicles reporting values for Engine Measurement Generic state of charge, which will include PHEVs, BEVS, and sometimes HEVs. If you have PHEVs and HEVs in your database, we advise that you customize this rule, and use the Publish to groups option to only apply the rule to a subset of the EVs in a Group.

    EV Enters Charging Zone with Low Charge

    document Image

    When an EV returns to a lot/depot with sufficiently low charge, it is time to plug in. This rule is useful for plug-in reminders and identifying which EVs need to be prioritized for charging.

    Important information and tips:

    1. This builds on EV Low Charge, and is more specific to plug-in reminders.
    2. The specified Battery charge looks at the Engine Measurement Generic state of charge.
    3. Create Zones around areas where your EVs stop and charge. Then assign those Zones to one or more designated Zone Types, and specify them here.
    4. Setting this rule to On via the built-in rule will enable it for all vehicles reporting values for Engine Measurement Generic state of charge, which will include PHEVs, BEVS, and sometimes HEVs. If you have PHEVs and HEVs in your database, we advise that you customize this rule, and use the Publish to groups option to only apply to a subset of the EVs in a Group .
    5. Have the plug in reminder go directly to the Driver by customizing the rule and choosing to Add driver feedback. See Understanding notification types in the Product Guide for more information.

    EV Exits Charging Zone with Low Charge

    document Image

    This rule will trigger when EVs exit a charging zone of the specified type(s) while its battery charge is below the configured value. This is useful for identifying EVs that:

    1. Leave the depot/lot at the start of their day with insufficient charge to complete their routes. This works well for cases when the EVs need a minimum charge to complete their expected route distance.
    1. Leave a wider geographic safe zone, such that by leaving this larger zone with a low charge, the EV no longer may have sufficient range to return to their regular charging location.

    Important Information and Tips:

    1. This builds on EV Low Charge, and is more specific to notify drivers that they are at risk of not having sufficient charge to complete their routes or make it back to their usual location to charge.
    2. The specified Battery charge looks at the Engine Measurement Generic state of charge.
    3. Create Zones around areas where your EVs stop and charge. Then assign those Zones to one or more designated Zone Types, and specify them here.
    4. Setting this to On via the built-in rule will enable it for all vehicles reporting values for Engine Measurement Generic state of charge, which will include PHEVs, BEVS, and some HEVs. If you have PHEVs and HEVs in your database, we advise that you customize this rule, and use the Publish to groups option to only apply to a subset of your EVs in a Group, such as to a BEVs group. See the Publishing rules to groups in the Product Guide for more information.
    5. Have the driver be alerted by customizing the rule and choosing to Add driver feedback. See Understanding notification types in the Product Guide for more information.

    EV Done Charging

    document Image

    This rule will trigger when the EV battery is charged to the configured value. This is useful to indicate when the EV’s charging plug can be provided to another EV, or when it is important to know when the EV is ready for use.

    Important information and tips:

    1. The specified Battery charge looks at the Engine Measurement Generic state of charge. Change from the default 100% value should you have your EVs configured to end charging lower than 100%.

    EV Stopped in Charging Zone and Not Charging

    This rule will trigger when an Electric Vehicle (EV) stops (ignition off) in a zone that has known charging stations, and does not start charging within the configured amount of time. This is to allow for time after the vehicle stops for the vehicle to get plugged in and start charging.

    For when EVs shouldn’t be plugged in, such as situations where there are more EVs than plugs, and the charge level remains sufficient to cover needs, it’s possible to enable this rule to be triggered only when the EV has a battery charge % (state of charge) less than the configured value.

    This is useful for identifying:

    1. Missed charging opportunities.
    2. When an EV is expected to be charging and is not. This could occur when an EV is not plugged in, or is plugged into non-functioning charging infrastructure.

    Report fields — EV specific meanings

    Below is a simplified list of EV-relevant fields in this report:

    Field

    Description

    Distance

    Total distance traveled on all energy sources.

    Electric Energy Used

    Total electric energy used during ignition on, expressed in either kilowatt hour (kWh) or watt hour (Wh). Wh is used when the Electric Energy Economy Measurement unit is set to Wh/km or Wh/mile; otherwise kWh is used.

    NOTE: Energy added to the battery from all non-charging sources — regenerative braking, driving down a hill, fuel engine charging in a hybrid — is subtracted from Electric Energy Used. If energy is added to the battery faster than it is consumed, the value will be negative.

    Fuel Economy

    This is displayed when the vehicle travels exclusively on fuel (electric energy used = 0); otherwise the field remains blank.

    Electric Energy Economy

    This is Electric Energy Used divided by Distance. This is displayed when the vehicle travels exclusively on electric energy (fuel used = 0); otherwise the field remains blank. It is a primary indicator of vehicle electric energy efficiency and performance.

    NOTE: See Electric Energy Economy Measurement to change the measurement unit.

    Similar to Electric Energy Used, if energy is added to the battery faster than it is consumed, the value will be negative.

    Total Fuel and Electric Energy Economy

    This is a single comparable value across all your vehicles and displayed for every vehicle. If electric energy is used, it is converted to the equivalent in fuel. This converted value is then added to the Fuel Used to calculate this combined Economy value. If electric energy is not used, this value is the same as Fuel Economy.

    Units = The equivalent of the selected fuel economy measurement. To learn how we convert electric energy to fuel, please refer to the note below.

    NOTE: Similar to Electric Energy Used, if energy is added to the battery faster than it is consumed, the value will be negative.

    % Electric Energy of Total

    Calculation of electric energy used (%), based on all electric and fuel energy usage. To learn how we convert electric energy to fuel, please refer to the note below.

    NOTE: When Electric Energy Used is negative, this value may exceed 100%.

    How do we convert electric energy to the equivalent in fuel?

    Both electricity and fuel are forms of energy. This report performs a conversion of electric energy to the equivalent in fuel to calculate the Total Fuel and Electric Energy Economy, and the % of Electric Energy of Total. For Battery Electric Vehicles (BEV), the equivalent in gasoline fuel is converted. For PHEV, the units convert to the same fuel type that’s used by the vehicle when the fuel type is reliably available.

    The United States Environmental Protection Agency (EPA) and the United States Department of Transportation (DOT) have adopted the standard conversion and states that 1 US Gallon of Gasoline is equivalent to 33.7 kWh of electric energy. Additionally, the United States Department of Energy Alternative Fuels Data Center defines 1 US Gallon of Diesel as having 113% of the energy of 1 US Gallon of Gasoline.

    Using these baseline conversions, including standard volume conversions to Liters and Imperial Gallons, we can convert electric energy to the equivalent in fuel.

    Electric energy economy measurement

    Similar to Fuel Economy Measurement, the Electric Energy Economy Measurement allows users to display measurements in the desired units.

    To change the measurement unit, follow the steps below:

    1

    document Image

    3

    Click Save.

    NOTE: The “-e” attached to L and MPG indicates that the unit converts electric energy to the equivalent in either liters or gallons of fuel. For BEVs, electric energy is converted into the equivalent in gasoline. For PHEVs, electric energy is converted into the same fuel type used by the vehicle as detected by the Telematics Device. The conversion requires the Telematics Device to accurately detect the fuel type, otherwise, the electric energy is converted to the fuel equivalent in gasoline.


    Electric energy economy measurement: metric

    Unit

    Description

    km/kWh

    For a primarily EV fleet, this helps you understand how much distance you can cover based on the battery energy — measured in kWh.

    L-e/100 km

    The best choice for a primarily non-EV fleet when the preferred fuel economy measurement is L/100 km.

    NOTE: This converts electric energy into the fuel equivalent (in liters) to present a value in familiar units. For BEVs, electric energy is converted into the equivalent in gasoline. For PHEVs, electric energy is converted into the same fuel type used by the vehicle — detected by the Telematics Device. The conversion requires the Telematics Device to accurately detect the fuel type; otherwise, the electric energy is converted to the fuel equivalent in gasoline.

    km/L-e

    The best choice for a primarily non-EV fleet when the preferred fuel economy measurement is km/L.

    NOTE: This converts electric energy into the fuel equivalent (in liters) to present a value in familiar units. For BEVs, electric energy is converted into the equivalent in gasoline. For PHEVs, electric energy is converted into the same fuel type used by the vehicle — detected by the Telematics Device. The conversion requires the Telematics Device to accurately detect the fuel type; otherwise, the electric energy is converted to the fuel equivalent in gasoline.

    kWh/100 km

    EV Charging report

    The EV Charging Report is the EV equivalent of the Fill-Ups Report used for fuel. This report provides information about the electric power and energy consumed when vehicles plug in to charge.

    What’s the difference between electric power and electric energy?

    Power, expressed in kilowatts (kW) or watts (W), is the rate at which electric energy is transferred into the vehicle for charging. The lower the power value, the longer the vehicle takes to charge.

    Energy, expressed in kilowatt hours (kWh) or watt hours (Wh), is the total volume of power transferred or used over an hour.

    EV Battery Health report

    ! IMPORTANT: This feature is not to be used for real-time data applications such as coordinating just-in-time deliveries or emergency operations.

    Overview

    EV Battery State of Health is a new report that calculates and displays the change in usable stored energy capacity over the lifetime of your Battery Electric Vehicles (BEVs) and Plug-in Hybrid Electric Vehicles (PHEVs), for the EV’s high voltage (HV) battery. It is available in Beta as of Fleet Management Application version 8.0.

    NOTE: Usable capacity versus actual capacity: Usable energy (kWh) capacity is that which the vehicle makes accessible for storage and vehicle operations, which may be different from what is physically available (actual).

    EV HV batteries degrade over time and under different conditions. The health of the battery over time is a new unknown impacting lifecycle projections, range and residual value. Use this report to gain visibility on the health of your EV battery.

    The current methodology uses historic data communicated by the vehicle to detect original usable energy capacity and current energy capacity. In the future, we will explore communicating values directly from the EV’s manufacturer / BMS (Battery Management System), which are not commonly reported in a standardized way.

    ! IMPORTANT: To determine which EVs receive support, visit the EV Make/Model Support Reference. The GO Plan is required.

    EV Battery Health Report questions answered

    Key Questions

    Answers

    How healthy are my EV (high voltage (HV)) batteries today, across all my EVs?

    Run the EV Battery Health report, for the most recent month, and view health %, which are a function of current detected capacity compared to original detected capacity.

    1. How quickly are my EV batteries degrading?
    2. How quickly am I losing usable (stored energy) capacity loss?

    Run the EV Battery Health, for the time period ‘Forever’ (which starts January 1, 2021) and see at a glance month over month usable capacity changes per vehicle.

    How does it work?

    Usable original capacity

    Original usable capacity is the detected capacity of the battery when the EV was first manufactured. It’s used as the comparison point for health. Battery capacity is detected monthly using a 90-day rolling average, and these detected battery capacities are compared to original capacity. The current methodology uses historic data communicated by the vehicle to detect original usable energy capacity.

    NOTE: Usable capacity versus actual capacity: Usable energy (kWh) capacity is that which the vehicle makes accessible for storage and vehicle operations, which may be different from what is physically available (actual).

    For accuracy and consistency, this is crowdsourced from the make, model, year, and trim of EVs across the Fleet Management Application customer base, when VIN decoding is available. These capacity values are compared with a single original capacity value for all EVs of the same make, model, year, and trim.

    To accurately detect the original capacity, input data is collected over approximately the first year of an EV’s life, from a set of the same make, model, year, and trim. Original capacity values will change month to month during the first year of an EV’s life as they become more accurate. The most recent and accurate values replace previously reported original capacity values for consistency and accuracy. For more information, see Why are the original capacity values in the report changing month over month?

    document Image

    Usable detected capacity

    A 90-day rolling average is used monthly to detect the battery’s usable capacity. The current methodology uses historic data communicated by the vehicle to detect usable energy capacity.

    NOTE: Usable capacity versus actual capacity: Usable energy (kWh) capacity is that which the vehicle makes accessible for storage and vehicle operations, which may be different from what is physically available (actual).

    Regular checks on usable capacity is the key to calculating changing health, in comparison to usable original capacity, and seeing capacity changes over time. Detected battery capacities are used in the EV battery health ratio compared to usable original capacity.

On the detectionDate, it represents a 90-day rolling average (see 90 Day Rolling Average Data Collection Start Date and 90 Day Rolling Average Data Collection End Date). If there is insufficient data to make an accurate detection, there are no results for that vehicle and month.

    90 Day Rolling Average Data Collection Start Date

    The date and time of the start of the 90 day rolling average window, relative to Detection Date, from which data is drawn towards a Detected usable capacity determination. This date is that of the first vehicle-reported data point in the dataset used towards the capacity determination.

    90 Day Rolling Average Data Collection End Date

    The date and time of the end of the 90-day rolling average window, relative to Detection Date, from which data is drawn towards a Detected usable capacity determination. This date is that of the last vehicle-reported data point in the dataset used towards the capacity determination.

    Odometer on Detection Date

    The vehicle’s odometer (km) on Detection Date.

    Usable detected capacity

    Monthly, a 90-day rolling average is used to detect the battery’s usable capacity. The current methodology uses historic data communicated by the vehicle to detect usable energy capacity.

    NOTE: Usable capacity versus actual capacity: Usable energy (kWh) capacity is that which the vehicle makes accessible for storage and vehicle operations, which may be different from what is physically available (actual).

    Regular checks on usable capacity is the key to calculating changing health, in comparison to original usable capacity, and seeing capacity changes over time. Detected battery capacities are used in the EV battery health ratio compared to original capacity.

    Description

    Usable detected capacity

    The usable detected capacity (kWh) is a 90-day rolling average. The single simplest value to use for usable battery capacity.

    This value is the mean of a normal distribution, and has associated 90% confidence intervals. See Usable detected capacity 90% Confidence Interval (+/-), Usable detected capacity Lower 90% Confidence Interval, and Usable detected capacity Upper 90% Confidence Interval.

    Do you see a usable detected capacity value greater than Original usable capacity? See Why do I see detected capacity values greater than original capacity values?

    Field

    Description

    Usable detected capacity 90% Confidence Interval (+/-)

    The usable detected capacity 90% confidence interval in kWh, relative to the mean of the normal distribution, Usable detected capacity.

    The lower boundary of the 90% confidence interval would therefore be Usable detected capacity minus this value. The upper boundary of the 90% confidence interval would therefore be Usable detected capacity plus this value.

    You can interpret this as 90% of the time, the usable detected capacity will be Usable detected capacity +/- this value.

    Usable detected capacity Lower 90% Confidence Interval

    Calculated value for the lower usable detected capacity 90% confidence interval in kWh. This is Usable detected capacity minus Usable detected capacity 90% Confidence Interval (+/-).

    You can interpret this as 90% of the time, the usable detected capacity will be within this value (Usable detected capacity Lower 90% Confidence Interval) and Usable detected capacity Upper 90% Confidence Interval.

    Usable detected capacity Upper 90% Confidence Interval

    Calculated value for the upper usable detected capacity 90% confidence interval in kWh. This is Usable detected capacity plus Usable detected capacity 90% Confidence Interval (+/-).

    You can interpret this as 90% of the time, the usable detected capacity will be within Usable detected capacity Lower 90% Confidence Interval and this value (Usable detected capacity Upper 90% Confidence Interval).

    Original usable capacity

    Original usable capacity is the detected capacity of the battery when the EV was first manufactured. It’s used as the comparison point for health. Battery capacity is detected monthly using a 90-day rolling average, and these detected battery capacities are compared to original capacity. The current methodology uses historic data communicated by the vehicle to detect original usable energy capacity.

    NOTE: Usable capacity versus actual capacity: Usable energy (kWh) capacity is that which the vehicle makes accessible for storage and vehicle operations, which may be different from what is physically available (actual).

    For accuracy and consistency, this is crowdsourced from the make, model, year, and trim of EVs across the Fleet Management Application customer base, when VIN decoding is available. These capacity values are compared with a single original capacity value for all EVs of the same make, model, year, and trim.

    To accurately detect the original capacity, input data is collected over approximately the first year of an EV’s life, from a set of the same make, model, year, and trim. Original capacity values will change month to month during the first year of an EV’s life as they become more accurate. The most recent and accurate values replace previously reported original capacity values for consistency and accuracy. For more information, see Why are the original capacity values in the report changing month over month?

    The usable original capacity (kWh) is the usable detected capacity when this EV was new. This is consistent across all make, model, year, when available via VIN decoding, and trim EVs. This value is the mean of a normal distribution, and has associated 90% confidence intervals. See Usable original capacity 90% Confidence Interval (+/-), Usable original capacity Lower 90% Confidence Interval, and Usable original capacity Upper 90% Confidence Interval).

    Battery Electric Vehicle (BEV) Range Capability Report

    Overview

    The Battery Electric Vehicle (BEV) Range Capability Report calculates the range capability for your BEVs - that is, the average distance your vehicles can travel on a full charge, based on your fleet’s operating conditions and historic energy consumption.

    Making full use of the range limits of your BEVs and reducing productivity loss incurred by unplanned charging stops is a new challenge as fleets add more and more electric vehicles. There are many different standards to calculate range capability, and some might be derived from calculations based on operating conditions that do not match your own fleet’s. The operating conditions that impact your range capability include seasonal temperature changes, speed (urban slower speeds vs. long distance higher speeds), terrain (hilly vs. flat terrain), cargo weight, heating and cooling the vehicle cabin, and driver behavior.

    The BEV Range Capability report seeks to address that need and gap, calculating the range that your BEVs are capable of doing based on the energy consumption during historic calendar months.

    ! IMPORTANT: Which vehicles are included in the BEV Range Capability report?

    Only vehicles detected as Battery Electric Vehicles (BEVs) will be included in the report.

    Vehicles detected as BEVs are automatically displayed within the Battery Electric Vehicle group under Asset Information > Asset Type > Electric or Hybrid Plug-in > Battery Electric Vehicle. Note that you can manually add or remove vehicles from this group if any vehicles are missing or incorrectly classified.

    To determine which EVs are supported, refer to the EV Make/Model Support Reference spreadsheet.

    Detection Date

    The date and time of the Range Capability determination. This is done monthly on the first day of the month.

    Detected Range Capability

    The vehicle’s range capability in the user’s set measurement units (kilometers or miles). This value represents the average distance that the vehicle is capable of traveling on a full battery charge, based on the average energy consumption observed over the distance traveled during the Period.

    The data elements that are used to calculate Range Capability include:

    1. Total electric energy used
    2. Total distance driven
    3. Detected usable battery size
  • Detected Electric Energy Economy

    The electric energy economy (in the user’s selected units) achieved by this vehicle during the Period. Answers: “How much distance was this BEV getting per kWh of usable battery capacity?”

    Detected Usable Battery Capacity

    The usable energy capacity (in kWh), detected during the Period, which the vehicle makes accessible for storage and vehicle operations. This value may be different from the physical battery capacity (actual).

    This value represents the mean of a normal distribution of various calculated battery capacity values and has an associated confidence interval of 90%. See the Usable Detected Capacity for more information.

    ! IMPORTANT: Why are the distance or energy values in this report different from other reports of the same duration?

    Not all trips may be used by this report to determine range capability. The range capability algorithm excludes outlier trips that may introduce inaccuracies to the results.

    Frequently Asked Questions

    Why are some of my vehicles showing no results at all, or no results for some time periods?

    Here are a few possible reasons:

    1. Only EVs (BEVs and PHEVs) that are supported will communicate results. See all supported EVs and make a request via your Partner for missing support.
    2. Ensure EVs are driven and charged regularly for the 90-day period prior to each detection date. Monthly usable capacity detections are made using several input sources that the EVs communicate over the previous 90 days from regular use. We only supply a monthly detection should there be enough input data to provide an accurate detection.
    3. Battery health detections started January 1, 2021.

    Why are there missing values?

    Applies to:

    1. EV Battery Health
    2. Original Usable Capacity

    The root cause for all missing values is missing usable original capacity values, which are currently auto-detected from EVs. The auto-detection process depends on a number of factors:

    1. VIN is fully detected. Today, VINs contributed via the Fleet Management Application are not used.
    2. VIN is fully decoded into a make, model, and year, when available via VIN decoding.
    3. Across all EVs in the Fleet Management Application customer base of the same make, model, year, when available via VIN decoding, and trim, insufficient data is collected at the start of vehicle life to make an accurate auto-detection.

    Why are the original capacity values in the report changing month over month?

    To accurately detect the original capacity, input data is used from a set of the same make, model, year and trim EVs, when it is available via VIN decoding. The data is collected over approximately the first year of the vehicle’s use. Month over month during that year period, original capacity can therefore change and updated for improved accuracy.

    document Image

    Why do I see detected capacity values greater than original capacity values?

    To provide a highly accurate determination of the original capacity of a given EV, data to determine the original capacity is collected from a sufficiently large sample of EVs sharing the same make, model, year, when available via VIN decoding, and trim. The sample is then averaged, with a 90% confidence interval available. Since original capacity is an average (mean), there will be cases, especially in the early life of an EV, whereby the detected capacity can be higher than the make, model, year, when available via VIN decoding, and trim original capacity determination. For these cases, we cap the EV battery health calculation at 100% to indicate that battery health is detected as the best it can be.
