Can fully charging my EV's battery really cause damage?

You may have heard somewhere that fully charging an electric vehicle could do more harm than good. But is that just an urban myth, or is there some truth to it? We’re revealing all in this article so you can be confident in the best way to charge your electric vehicle. We’ll also help you find the sweet spot between getting the optimum amount of battery power while ensuring your battery is taken care of to encourage longevity. 

Will charging my EV to 100% really damage the battery?

Charging an electric vehicle (EV) to 100% can cause damage to the battery over time. 

Consistently charging to 100% capacity can promote the growth of lithium metal tendrils known as dendrites, which can cause a short circuit and reduce the battery's longevity. 

It is advisable to follow the manufacturer's recommendations and charge 100% only when necessary, such as before a long trip. 

In fact, charging 100% is regarded as one of the biggest (and most common) mistakes of EV owners. 

By keeping your charge range between 30-80%, you can keep your battery in good health and hopefully get more mileage out of your vehicle in the long-term. 

Sure, not being able to fully charge your car may be a little frustrating. But it will benefit you and your pocket in the long run. 

How much should you charge your EV by in one go?

While it is not discouraged to occasionally charge an EV to 100%, for normal day-to-day charging, it is considered best to charge to 80% to ensure the longevity of the battery. Charging can also slow down past the 80% mark, affecting charging performance.
