How to Check EV Battery Health?

Knowing if your EV battery is in good shape is important for safe and trouble-free driving. With a few simple checks, you can find out if your battery is healthy or if it needs attention. Follow these steps to check your EV battery health easily.

Step 1: Charge the Battery Fully

Start by charging your electric vehicle until the battery is 100% full. Use the recommended charger for best results.
A full charge helps you get the most accurate information about your battery’s condition.

Step 2: Check the Estimated Driving Range

After charging, look at the dashboard to see the estimated driving range. This shows how far your car can go on a full battery.
If this range is much lower than what was promised when the car was new, the battery may be losing strength.

Step 3: Do a Simple Range Test

Drive your car a set distance and note how much the range drops on your dashboard. Compare the actual distance traveled with the range that was used.
If the range drops faster than the distance you drive, it could mean the battery is wearing out.

Step 4: Watch Charging Times

Keep track of how long it takes to charge your battery from empty to full. Normally, charging time should stay about the same each time.
If you notice charging takes much longer than usual, this could be a sign of a weaker battery.

Step 5: Use Battery Diagnostic Tools or Apps

Many EVs come with built-in tools or apps that give information about the battery’s health. These tools can show the “State of Health” (SoH) of your battery.
A higher SoH means your battery is still strong, while a lower SoH shows it has lost capacity.

Step 6: Look for Warning Signs

Watch for things like reduced driving range, slow charging, odd smells, or overheating during charging. These are all signs that the battery may not be healthy.
If your car seems slower or struggles to perform, it might also be a battery issue.

Step 7: Get a Professional Battery Check

If you are unsure or notice warning signs, visit a certified service center. A professional can do a complete battery health check using special tools.
Regular expert checks help catch battery problems early and keep your EV running smoothly.

Considerations That Will Improve the Longevity of Your EV

Keeping your EV running well for many years is something every owner wants. Small daily habits can really make a big difference in your car’s life. It doesn’t take a lot of effort, just a few simple steps that are easy to remember. Here are some important things you can do to help your EV last longer.

Temperature Care

Try not to park your car in very hot or freezing places for a long time. Heat can make the battery lose power faster, and freezing cold isn’t good for it either. Parking in the shade or in a garage can really help. Before you start driving, use the car’s heating or cooling system to make the battery’s temperature just right. This helps keep your battery in good shape over time.

Smart Charging

Don’t charge your battery to 100% all the time, and don’t let it drop to zero either. The best range to keep your battery healthy is between 20% and 80%. When charging, it’s a good idea to use a trusted charging station like the Crack Platoon EV charger for safer and more reliable results. Try not to use fast charging unless you really need to, as normal charging is slower but much better for the battery’s long-term health. Following these habits will help your EV battery last longer and work better.

Gentle Driving

Avoid speeding up too quickly or stopping very suddenly. These actions use more battery power and can wear it out faster. Try to drive smoothly and let your car slow down naturally when you can. Using regenerative braking helps recharge the battery a little bit while driving. Smooth driving is always better for your car.

Regular Checkups

Take your car for regular maintenance, just like you would with any other vehicle. Listen for any strange sounds or warning lights on your dashboard. Make sure to follow the service schedule in your car’s manual. Keeping your car’s software up to date can also help the battery last longer. Regular care means fewer surprises later.

Storing the Car

If you are not going to use your EV for a long time, keep the battery around half full. Don’t leave it at a full or empty charge for weeks. If you can, store your car in a place where the temperature doesn’t change too much. This helps the battery stay healthy even when you’re not driving.

Keep Up With Updates

Manufacturers often release updates for your EV that help the battery work better. These updates can fix problems or make charging safer and smarter. Check if your car can get updates automatically or if you need to visit a service center. Staying updated helps you get the most out of your car.

Signs Your EV Battery May Need Attention

It is important to know when your EV battery might have a problem. If you spot these signs early, you can fix things before they get worse. This will help you stay safe and keep your EV working well. Here are some simple signs to watch for with your battery:
