5 Proven EV Battery Maintenance Tips for Best Performance

Follow these simple electric vehicle maintenance best practices to improve battery longevity and performance:

1. Use the Right Charging Levels and Infrastructure

You must use appropriate charging levels (battery charging speeds) and a reliable EV charger to maintain your EV battery life. Here’s a quick overview of the different charging levels: 

Note: A faulty charger or poorly maintained charging infrastructure can accelerate degradation by causing battery charging problems like uneven or rapid charging, overcharging, and overheating

2. Maintain an Optimal State of Charge

Whether you drive your EV daily or plan to park it for a week, month, or more, it’s best to maintain the battery within an optimal charge range of 20% to 80% battery capacity. Frequent fast charging to 100% or deep discharges (below 20%) can accelerate battery degradation, leading to sluggish acceleration, weak braking, and reduced battery life.

Limiting the EV battery charge to less than 80% also allows the car to use regenerative braking for producing and storing energy. 

What’s regenerative braking?
It’s an energy recovery mechanism that converts kinetic energy generated during braking into electrical energy.

3. Minimize EV Battery Exposure to Extreme Temperature 

EV battery degradation speeds up when exposed to extreme temperature conditions. If the battery pack gets too cold, it reduces power. And if it gets too hot, it can wear out faster. 

So, park your car indoors, use a cover, or find shade to maintain battery health when it’s hot or freezing outside.

And that’s not all!
Before charging the EV battery pack, use the preconditioning feature to adjust your car’s cabin and battery to the operating temperature. This helps improve charging efficiency and maintain battery health in the long run.

4. Limit High-Speed Driving 

When driving at high speeds, your electric car battery generates more heat to power the vehicle. Over time, this can shorten the EV battery life. 

Maintaining moderate speeds allows the battery to operate more efficiently and effectively.

Under-inflated EV tires create more friction with the road surface, causing your EV to consume more energy to move forward. This results in a shorter driving range per charge, uneven tire wear, reduced tire lifespans, and compromised vehicle handling and safety.

Modern EV owners or EV drivers can also refer to their owner manuals for electric vehicle maintenance tips on charging, operation, battery repair, and software updates.

4 FAQs about EV Batteries

Here are answers to four common questions about EV batteries: 

1. How Do EV Car Batteries Work?

An electric vehicle battery stores energy to power the vehicle’s electric motor. Here’s how it operates:

2. What Are the Types of Electric Car Batteries? 

Here are some of the main types of EV car batteries:

3. How Long Do Electric Car Batteries Last?

An EV battery pack lasts 15 to 20 years or up to 200,000 miles. However, the actual EV battery life can vary based on battery usage, the type of battery, driving conditions, and maintenance practices.

Note: Proper disposal of old or damaged EV batteries is crucial as they are highly flammable and toxic.

4. How Much Does an EV Battery Replacement Cost?

An electric vehicle battery replacement for a lithium-ion battery typically costs between $6,500 to $20,000, depending on the type of battery. The final price depends on the battery size, manufacturer, vehicle make, and mechanic’s labor charge.

Note: If battery degradation occurs during the warranty period, the manufacturer may replace it free of cost.
