Telematics monitors your EV battery health by using the vehicle data it captures to keep track of the State of Health (SoH), the State of Charge (SoC), and the thermal data. If you want to prevent range anxiety and improve battery health, you should be keeping an eye on these metrics.
According to a comparative study that was conducted in 2025 on more than 30,000 electric vehicles and the lowest-performing 1% of the group saw a battery health drop of 80.8%. However, the average battery health for the majority of the EVs aged at around 4 to 5 years old, maintained 93.5%
What this data proves is that the performance gap isn’t caused by age and usage. It shows that operational habits are the main cause of battery health decline. This is where telematics comes in. Telematics data will give you a comprehensive overview of your entire fleet so you can make sure your EV vehicles are always performing at their best and that they’ll last you a long time.
You should monitor your EV’s battery health so that you can protect your investment. EVs are significantly more expensive compared to your normal ICE vehicles. The parts of these vehicles also cost a pretty penny, and when you keep a watchful eye on your battery health, you can ensure that your asset is going to last you a long time.
When you monitor your EV's battery health, you can get the most out of your driving range and make sure everything is working as it should, ensuring the safety of the driver. Another benefit is that you can prevent battery degradation, and you’re ultimately protecting your vehicle’s resale value.
Another major reason you should monitor your EV’s battery health is because you can resell EV batteries. They’re often used for home solar backups. Telematics gives you reports that let you prove that your EV batteries still have a high SoH so that you can get the most value out of the batteries you’re selling.
EV battery degradation is just the simple and natural process of your battery’s ability to hold a charge over time. We’ve all experienced this with our cellphones; when it's new, it could last you two days, but after a few years, you’re charging it multiple times a day. For electric vehicles, battery degradation directly affects your driving range and performance.
It’s important to note that most battery degradation happens in the first couple of years, and then it’ll slowly decline after that. To minimise battery degradation, you can do the following things:

Telematics is used for EVs by tracking and monitoring your EV in real time; it’ll track energy usage data and charging time slots. But above that, a telematics system can optimise your entire EV fleet, thanks to features like maintenance alerts and energy consumption reports.
A telematics system can optimise your EV fleet operations by giving you complete insights into how your EVs are performing. With the insights provided you’ll be able to schedule vehicle charging during quiet periods and identify which electric vehicle in your fleet is best for each trip that’s needed each day.
Real-time GPS tracking lets you adjust schedules on the go, and the detailed reports you receive will provide you with the evidence you need to improve any strategies and productivity. Having a telematics system for your EV fleet not only assists with battery health, but it also transforms the way you manage your entire operation.
The key features of a telematics system for EVs include battery monitoring, charging insights, route optimisation, driver behaviour, predictive maintenance and range prediction. If you’re unsure as to why you need a telematics system for the EVs in your fleet, here’s a breakdown of the features you’ll get.
The most important thing you need to do if you have an EV in your fleet is that you have to keep track of SoC, SoH, temperature and voltages. Without these insights, the integrity of the batteries is compromised. By monitoring the battery health, you’ll be able to keep them in the best condition for as long as possible. We know EVs are expensive, so this makes sure you get the most out of your vehicle.
To power your EVs, their batteries need to be charged. As a fleet owner you need to know the charging status of each and every EV in your fleet. A telematics system will send you notifications for all types of charging statuses (completed, interrupted, and low battery.)
You also need charging insights on your EVs. With telematics you’re able to get insights on each electric vehicle’s charging history, and on top of that you can create a proactive charging schedule. By having a proactive charging schedule, you’ll never be behind schedule because some of your EVs didn’t get charged the day before.
Range anxiety is a real problem for anyone who owns an EV. Telematics is the solution to ease your worries with predictive insights. These insights will let you know how far your EVs can travel by looking at energy use, charging habits, and the terrain that’ll be travelled. This way you’ll know exactly when your vehicle needs to be stopped to get recharged.
Parts for electric vehicles are not exactly cheap. But when you connect your EVs with a telematics system, you’ll get alerts on all exterior, system and battery issues so you can schedule maintenance before they affect your fleet. A simple thing like having underinflated tyres can cause a major decrease in the KMs your EV will get.
From the stats mentioned at the beginning of this blog, we see that the longevity of your EV’s battery is directly linked to driver behaviour. Telematics will give you comprehensive insights on exactly how your drivers are handling your EVs; are they speeding, taking corners aggressively or braking harshly? This data will allow you to give your drivers proper coaching to handle the EVs, and you can ultimately improve the lifespan and performance of your EVs.
You want to get the most KMs out of your EVs, and you can achieve this with a telematics system. Thanks to advanced GPS tech, telematics can help plan the best routes for your EVs to take, making sure they avoid traffic, unkept roads and unnecessarily long routes, all of which contribute to decreased energy use.

To do a detailed EV battery health check, there are a few things you need to do, such as check the battery health, the actual EV range, and the SoH and install a telematics system. By following this procedure, you’ll be able to make sure your EV's battery health is in tip-top condition.
You should choose Cartrack as your EV fleet partner because our telematics software is designed to work on any fleet. It doesn’t matter if your fleet is fully EV or if it’s mixed. You're able to use one single platform for all of them. And we don’t just work with your LMVs or trucks; we can work on your electric scooters, forklifts and buses too.
With Cartrack, we’ll provide you with:
