EV Charge Monitoring

Monitor your electric fleet's live charging to improve dispatching and queue times.

The EV Charge Monitoring page provides a real-time overview of your electric fleet's charging status to support dispatch planning and queue management.


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 management 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 main view provides summary tiles and a vehicle table with real-time charging data.

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
Asset	The name of the EV asset.
EV Charging Rule (Summary Tile)	Provides a count of vehicles that have violated EV management 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 management 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.

Note:

Summary cards display only when vehicles in your fleet match the card's data criteria. Depending on your fleet's EV statuses, not all summary cards may be visible at all times.

Why are certain values not available?

Learn more about the reasons why certain values may not be available on the EV Charge Monitoring page.

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)


Problem	Solution
Signals are not supported by your current plan.	Vehicles connected with a GO devicemust be connected using the GO plan. Check the list of electric vehicles supported on the GO device. SeeEV Make/Model Support Reference. For vehicles connected via OEM telematics, ensure that the OEM is providing these diagnostic signals.
The device is not communicating.	Use theAssetspage to identify and troubleshoot devices that have gone offline.

EV Charging Exceptions


Problem	Solution
You have not enabled any built-inEV management rules.	Enable the built-inEV management rules.
There have been no recent exceptions to the built-inEV management rules.	Check back later once exceptions occur.
You do not have permission to view exception data.	Users must have a security clearance that includes the "View Exceptions" permission.

Location


Problem	Solution
The device is not communicating.	Use theAssetspage 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


Problem	Solution
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


Problem	Solution
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.

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

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.
