Electric vehicle battery degradation tool for fleets

Discover how long your EV battery will last.

What is electric vehicle battery degradation?

​​Battery degradation is a natural process that permanently reduces the amount of energy a battery can store.

A battery’s condition is called its state of health (SOH). Batteries start their life with 100% SOH and over time they deteriorate. SOH is a measure of how much energy the battery can deliver (kWh).

While there has been plenty of research done on battery health, there has been very little data following the real-world performance of EVs over time, let alone comparisons across different makes and models.

Until now.

How do you determine how long your EVs battery will last?

If you’re considering adding electric vehicles to your fleet, understanding how quickly EV batteries will degrade will help you be more confident in your decision, as capacity loss will impact range, cost of ownership, and expected residual value.

Geotab can help by sharing how vehicle batteries are performing to-date. View aggregated average data for 24 vehicle makes and models using our free Electric Vehicle Battery Degradation tool. Our dataset is based on real-world battery health measured from 6,300 fleet and consumer EVs representing 1.8 million days of data.

Compare battery degradation by vehicle model

The Electric Vehicle Battery Degradation Tool lets you compare battery degradation over time for different vehicle makes and model years.

Note: only models are included where Geotab has sufficient data to display. This tool will be updated periodically as more data is collected and analysed.

Learn more about what impacts battery health in our blog post.

Notes about the tool:
• The degradation curves displayed are the average trend line from the data analysed.
• These graphs should be taken as a general insight into battery health, not a precise prediction for any particular vehicle.
• A subset of vehicle makes, models, and years are not available in the visualisation tool— we have excluded vehicles with insufficient data. (Don’t be alarmed if your car of choice is missing!)

Commonly asked questions

The Electric Vehicle Battery Degradation Tool lets you compare battery degradation over time for different vehicle makes and model years. Degradation is based on observed data so newer model years will have shorter degradation lines.
