If you want to be a savvy EV owner, you’ll need to know the best practices to protect your battery's lifespan. You may want to go all-in with superfast electric vehicle (EV) charging, but you wonder whether fast charging could have an impact on the degradation of your EV battery. We’re revealing all in this guide.
The good news is that the effect on battery health is generally minor with sporadic use of the fast charger. However, while quick charging may not cause immediate harm to the battery, repeated and sustained use of fast charging can lead to long-term battery health issues.
Research shows that frequent fast (DC) charging can degrade the battery faster than AC charging, increasing battery deterioration by about 0.1% on average.
Temperature management is also a critical factor in preserving battery health, as lithium-ion batteries are sensitive to high temperatures.
Most modern EVs are equipped with built-in temperature management systems to protect the battery, even during fast charging.
It's important to note that the impact of fast charging on battery health can vary depending on the specific make and model of the EV, as well as the battery management system it employs.
It’s recommended that you resort to fast charging sparingly and only when you really need it. It’s best to plan for convenient times to leave your vehicle charging on a slower setting. There’s no risk of overcharging, so you don’t need to keep checking on progress. You can simply leave it to do its thing.
However, if you find yourself cut short on power (all motorists have been there), then don’t be afraid to use the fast charger to give your vehicle the boost it needs to get you from A to B with confidence.
We hope this article has answered all your questions on whether rapid charging can damage your EV battery. In summary, it’s fine to use the rapid charger as and when you need it, but not to rely on it every time you need a power top-up.
