If you’re noticing that your EV doesn’t take you as far on a full charge as it used to, it could be a sign that the battery is wearing out.
Longer charging times
Another indicator could be longer charging times. If it’s taking significantly longer to charge your EV than it used to, the battery might be approaching the end of its lifecycle.
Battery management system warnings
Modern EVs come equipped with a battery management system (BMS) that monitors the health of the battery. Warnings or alerts from this system should not be ignored.
Visible damage or swelling
Lastly, physical signs like visible damage or swelling of the battery are clear indicators that it’s time for a replacement.
Average Lifespan of EV Batteries
Manufacturer claims vs. real-world experiences
Manufacturers might claim a lifespan of up to 15 years under ideal conditions, but real-world experiences can vary. Factors such as those mentioned earlier can lead to batteries needing replacement sooner. However, with proper care, reaching or surpassing the decade mark is certainly achievable for many EV owners.
Comparison with internal combustion engine vehicle lifespans
Compared to the internal combustion engine (ICE) vehicles, EVs have fewer moving parts but the battery’s lifespan can be a consideration point. While an ICE vehicle might need more frequent maintenance, the major expense of replacing an EV battery is usually a one-time event in the vehicle’s life.
