California leads the way in electric vehicle (EV) ownership, with drivers all over the state making the switch to greener, cleaner rides. Are you one of them? If you own an EV, you know there’s a lot more to charging than just plugging it in. To get the most out of your vehicle, you need to understand how. Here’s how smart charging habits can improve performance and maximize the life of an EV battery.
Why Electric Vehicle Battery Health Matters
Smart charging isn’t just about convenience or cost savings, it’s also about protecting one of the most valuable parts of your EV. Your EV’s battery is the heart of your car. It’s important to take care of it so you can enjoy longer range, better vehicle performance, and fewer costly replacements down the line.
Seven Tips to Prolong EV Battery Life
1. Don’t Charge to 100%
While it might be tempting to top off your battery at 100% every time you charge it, doing so can actually degrade your battery. Most EV manufacturers recommend only charging up to 80% for daily use. A full charge is not necessary for short commutes. Save the 100% charge for long road trips, like a weekend drive up the Pacific Coast Highway.
2. Don’t Let the Charge Drop Too Low
Just as over-charging can strain your battery, so can letting the charge drop too low. Try to keep your battery level above 20% when possible. Smart charging apps like CaliCharge can alert you when your charge level dips too low.
3. Charge During Off-Peak Hours
Electricity gets more expensive between 4 pm and 9 pm when it’s in high demand. By charging your EV during off-peak hours (usually overnight), you can take advantage of lower electricity rates while reducing strain on the grid. The CaliCharge app can automatically schedule your EV to charge when electricity is cheapest.
4. Watch the Weather
Extreme heat or cold can affect your battery’s performance and longevity. While California’s climate is generally EV-friendly, inland regions like the Central Valley and deserts can hit scorching temperatures in the summer.
To protect your battery, make sure to:
- Park in a garage or shaded area whenever possible
- Avoid charging during extreme heat
- Use scheduled charging so your battery warms up or cools down before you hit the road
5. Use a Smart Charging App
A good smart charging app doesn’t only make charging easier—it also helps extend battery life and save you money.
For example, the CaliCharge app can help you:
- Optimize charge times for better battery health
- Monitor your charging habits
- Remember to charge when your battery is low
- Take advantage of utility incentives and off-peak rates
- Reduce your carbon footprint by charging when renewable energy is more abundant
6. Avoid Fast Charging All the Time
Direct Current Fast Charging, also known as DC Fast Charging or DCFC, makes charging more convenient, especially during road trips. However, fast charging all the time can generate excess heat and wear down your battery more quickly. For daily driving, level 2 home charging is usually sufficient and better for your battery in the long run.
7. Stay Updated with Software & Battery Health Reports
EV manufacturers often release software updates that enhance battery life and efficiency, so make sure that you’re using the current version. Some EVs also provide periodic battery health reports via a battery management system. These give insights into how your battery is aging and how your charging habits may be affecting it, so you can make adjustments as necessary.
