4. What Happens During an EV Battery Health Inspection?

When you take your EV for a battery inspection, a professional technician will perform a series of tests to evaluate the battery’s condition. Here’s what they typically check:

A. Visual Inspection

The technician will check for any visible damage or wear on the battery pack, such as cracks, leaks, or corrosion around terminals. Even minor issues can escalate if left unchecked.

B. Voltage and Capacity Testing

A critical part of the inspection is testing the battery’s voltage and overall capacity. This helps determine if the battery is holding a charge effectively or if individual cells are degrading.

C. Charge/Discharge Test

A test may be done to simulate charging and discharging cycles to evaluate how well the battery delivers and accepts power. This also helps identify whether the battery has a problem with voltage drops under load.

D. Battery Management System (BMS) Check

The BMS will be checked to ensure it’s operating correctly and monitoring the battery’s performance. If there are issues with the BMS, it can lead to inaccurate readings or even prevent the battery from charging properly.

E. Thermal System Check

Since temperature management is critical for battery health, technicians will ensure that the cooling/heating system is functioning. If there are problems with the thermal management, it can lead to overheating, which accelerates battery degradation.

5. When Should You Replace Your EV Battery?

EV batteries typically last between 8-10 years or 100,000-150,000 miles, depending on the vehicle and usage. However, if you notice severe capacity loss, frequent power loss, or other critical issues that can’t be resolved through repairs, it may be time for a replacement.
