Optimizing your EV fleet with notifications and rules

Explore the rules in MyGeotab to help manage your EV fleet.

How can you get your drivers to remember to plug in their EV when they return to the lot? How do you make sure a driver isn’t leaving the depot with insufficient charge? While these may seem like tough questions, they have simple answers: by utilizing MyGeotab rules for electric vehicles.


MyGeotab is an easy to learn, fleet management application that offers comprehensive solutions for collecting and managing data. For successful EV management, four built-in electric vehicle (EV) rules are a part of the MyGeotab platform. These proactive notifications and alerts help manage EVs in the fleet, specifically related to charging activity. Read on to learn more about the rules and how they can help your fleet.

EV Low Charge

This rule helps you receive a notification to know when an EV has dropped below a specified charge percentage level and is at risk of not completing its daily routes. Never worry about a vehicle not having sufficient charge to complete its route with this custom trigger notification. Fleet managers can prevent EVs from getting stranded with insufficient charge, or forcing an unplanned charging stop during the day which would create a large productivity and time loss for the driver.

EVs Entering Zone with Low Charge

When an EV is returning to a depot or lot with sufficient low charge, it needs to be plugged in. This will provide drivers with a reminder that their EV needs to be charged. It can also help fleet managers identify which EVs need to be prioritized and charged first.

Tip: 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 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 the EVs in a Group, such as to a BEVs group.

EVs Leaving a Zone with Low Charge

This rule will trigger a notification when EVs leave a charging zone of the specified types while their battery charge is still below the configured value. This rule will be extremely useful for identifying EVS that are:

  • Leaving an area which has a wider geographical safe zone with a low charge which will put their EV at risk of not having sufficient range to be able to return to a charging location.
  • Leaving a lot or depot such as a city center without their vehicle not charged enough in order for them to successfully complete their route. This is useful in cases when EVs need a minimum charge to complete their expected route distance.

A fleet manager does what they can to ensure EVs are sufficiently charged before they start their day. Use this rule to catch those exceptional times when your regular checks have failed.

EV Done Charging

This rule will trigger when an EV is charged to the configured value. This helps fleet managers prioritize charging schedules by knowing when an EV is done and fully charged so the next one can plug in.

Tip: The battery charge takes into account the engine measurement generic state of charge. If your configured value is lower than 100%, change the default to whatever figure you would like to get the notification at.

Add value to your fleet

There are many other existing rules in MyGeotab for optimal EV management. Two helpful ones include:

  • Identifying when a plug-in hybrid electric vehicle (PHEV) is running on fuel only and not optimizing its electric cost-savings potential.
  • Establishing no-charge time rules to eliminate charging during peak electricity rate times and receive notifications when a vehicle is charging during that time.

Using the rules in MyGeotab removes the guesswork that goes into managing an EV fleet. Figure out what the priorities for your fleet are, and see how the rules can help simplify your day-to-day work.

How Geotab can help

These rules above, plus the others available in MyGeotab allow fleet managers to proactively manage their EVs to prevent issues and proactively measure performance. At Geotab, we believe in “management by measurement,” and that is exactly what these rules are created for. As a fleet manager, you will be alerted when something is going wrong or about to go wrong, so problems can be solved quickly and more efficiently.
