Key Questions

Answers

Are vehicles charging when they should be? Help me identify and resolve charging issues.
  • Exceptions: Identify vehicles with recent exceptions to EV exception rules.
  • Configurable filters: Search for concerning vehicles (for example, Not charging and SOC < 40%).

When will vehicles be done charging? Help me plan for dispatch.
  • Charge Complete Time: Understand when vehicles will reach 90% SOC, given their current charging rate.
  • Range Remaining: Evaluate whether a vehicle can be dispatched immediately, or if it needs more charging.

Which vehicles should charge next? Help me manage a queue of vehicles waiting to charge.
  • Full charge: Identify vehicles that have a full charge. These could be moved off chargers, to make room for other vehicles to plug in.
  • Low charge: Identify vehicles that have low charge. These are candidates to plug in next.
  • Range Remaining: Evaluate whether a vehicle can be dispatched immediately, or if it needs more charging.

Main view

The EV Charge Monitoring page, accessible via Fuel and Energy > EV Charge Monitoring, provides a comprehensive overview of your electric fleet's current charging status.

Page Element

Description

EV Charging Rule (Summary Tile)

Provides a count of vehicles that have violated EV exception rules in the last 24 hours. Clicking on the summary tile filters the table to show only vehicles with recent rule violations.

Note:

Enabling the built-in rule EV Stopped In Charging Zone and Not Charging should allow you to identify the majority of charging issues.

Note:

EV Charge Monitoring displays exceptions to built-in EV charging rules, but not custom charging rules.

Full Charge (Summary Tile)

Provides a count of vehicles with >90% State of Charge. Clicking on the summary tile filters the table to show only vehicles with a State of Charge greater than 90%.

Low Charge (Summary Tile)

Provides a count of vehicles with <30% State of Charge. Clicking on the summary tile filters the table to show only vehicles with a State of Charge less than 30%.

Charging (Summary Tile)

Provides a count of vehicles that are currently charging. Clicking on the summary tile filters the table to show only vehicles that are currently charging.

Not Charging (Summary Tile)

Provides a count of vehicles that are not currently charging. Clicking on the summary tile filters the table to show only vehicles that are not charging.

Charging status

Indicates whether or not a vehicle is charging. This field is based on the diagnostic signal "Electric vehicle charging state".

EV charging exceptions

Lists EV exception rules that have been violated in the last 24 hours. Click the red pill to see the exception details.

Note:

Enabling the built-in rule EV Stopped In Charging Zone and Not Charging should allow you to identify the majority of charging issues.

Note:

EV Charge Monitoring displays exceptions to built-in EV charging rules, but not custom charging rules.

State of charge

Indicates the charge level of the battery. This field displays the diagnostic signal "Generic state of charge".

Charging power

Indicates the rate that energy is entering the battery. This field displays the diagnostic signal "Electric vehicle battery power".

Charge complete time

For vehicles that are currently charging, this field shows the time when they will reach 90% State of Charge.

Note:

Charge Complete Time assumes that the current charging power will continue until the vehicle reaches 90% charge. This may not always be a good assumption, especially if charge station software is used to make adjustments to charging power.

Remaining range

Remaining Range is the distance the vehicle can drive, given its current state of charge. Remaining Range values are displayed in the form XX +/- YY, where XX is the most likely range remaining for this vehicle, based on its recent driving history, and there is a 90% probability that the true range remaining lies between XX-YY and XX+YY.

Location

The last known location of the vehicle.

Filter panel

Clicking on Filters on the EV Charge Monitoring page opens a filter panel. Use the filter to show only the vehicles that are relevant to you.

For example, to see only Battery Electric Vehicles belonging to the Toronto group that are Not Charging and have a State of Charge between 0 and 40%, select those values in the filter panel.

For vehicles not appearing in EV Charge Monitoring, check that the vehicle is supported. See EV powertrain automatic group classifications for more information. Use the Assets page to identify and troubleshoot devices that have gone offline.

Why are certain values not available?

Missing values in EV Charge Monitoring are typically caused by unsupported plans, offline devices, disabled exception rules, or insufficient permissions.

Diagnostics (Charging State, State of Charge, Charging Power)

The most common reasons that EV diagnostic signals are not available are:

  • These signals are not supported by your current plan.
    • Vehicles connected with a GO device must be connected using the GO plan.
    • Check the list of electric vehicles supported on the GO device.
    • For vehicles connected via OEM telematics, ensure that the OEM is providing these diagnostic signals.
  • The device is not communicating. Use the Assets page to identify and troubleshoot devices that have gone offline.

EV Charging Exceptions

The most common reasons that exception data is not available are:

  • You have not enabled any built-in EV exception rules.
  • There have been no recent exceptions to the built-in EV exception rules.
  • You do not have permission to view exception data. Users must have a security clearance that includes the "View Exceptions" permission.

Location

The most common reasons that location data is not available are:

  • The device is not communicating. Use the Assets page to identify and troubleshoot devices that have gone offline.
  • You do not have permission to view location data. Users must have a security clearance that includes the "Display the map and show live tracking" permission.

Charge Complete Time

The most common reasons that a Charge Complete Time estimate is not available are:

  • The vehicle is not charging. Charge complete time is only estimated for vehicles that are currently charging, with a state of charge less than 90%.
  • There is not enough historical data collected for this vehicle. The data model requires about a month of regular driving and charging to make an accurate prediction of battery capacity and charge complete time. It is normal for newly connected vehicles to show blank values for the first one to two months they are active in the system.
  • You do not have permission to view charge complete time. Users must have a security clearance that includes the "Access Time-to-Charge Complete API" permission.

Remaining Range

The most common reasons that a Range Remaining estimate is not available are:

  • There is not enough historical data collected for this vehicle. The data model requires about a month of regular driving and charging to make an accurate prediction of EV range. It is normal for newly connected vehicles to show blank values for the first one to two months they are active in the system.
  • You do not have permission to view EV range data. Users must have a security clearance that includes the "View EV Performance Data" permission.

How should I interpret the values provided for Range Remaining?

Range Remaining estimates how far a vehicle can drive given its current state of charge, expressed as a range that reflects uncertainty in real-world conditions.

Remaining Range is the distance the vehicle can drive given its current state of charge.

EV range is impacted by a number of factors, including weather, speed, altitude change, payload, and driving style. Because these factors are constantly changing, it is difficult to predict EV range remaining precisely. Range predictions always carry some level of uncertainty.

Range remaining values are displayed in the form XX +/- YY, where:

  • XX is the most likely range remaining for this vehicle, based on its recent driving history.
  • There is a 90% probability that the true range remaining lies between XX-YY and XX+YY.
