August 22nd, 2023 by

As we move further into 2023, some scientists are predicting this may be the warmest year that human civilization has ever experienced. For electric vehicle (EV) owners in California, this means taking extra care to protect your battery from extreme heat. Our friends at Recurrent have put together some great info to help keep your EV in top condition – check it out!

Finding the Sweet Spot for Your Battery

Electric vehicle batteries operate optimally between 60°F and 90°F. Within this range, the performance and lifespan of your battery are at their best. At higher temperatures, battery particles move faster, which makes charging and discharging more efficient (that’s good). But beware, excessive heat can also speed up battery degradation (that’s not so good).

5 Tips for Safeguarding Your Battery in the Heat

1. Avoid Extreme Charging: During intense heat, it’s best to keep your vehicle half charged rather than fully charged.

2. Mind Your Charging Times: If possible, avoid fast charging during the hottest parts of the day.

3. Seek the Shade: Whenever you can, park in shaded areas to shield your car from direct sunlight.

4. Stay Plugged In: Keeping your vehicle plugged in prevents the BMS from draining your battery while managing the temperature.

5. Learn More: For those interested in a deeper understanding, take a look at Recurrent’s guide to lithium-ion batteries and heat.

The great news for drivers is that your electric vehicle is engineered to withstand the heat. Follow these simple tips, and your EV’s battery will thank you.
