Replacing an EV battery is considered an expensive and daunting task. While batteries can be expensive, most EV manufacturers design the battery packs so they can outlast the journey of the vehicle. After 10+ years, some older EV models like the Mitsubishi MiEV are actually still driving around our cities on their original battery packs.
Tesla’s 2022 Impact Report (PDF, 35.2 MB) revealed that (320,000km). If you’re only driving 12,000km a year, your EV’s battery could last up to 26 years. Even after 26 years, your battery could still be delivering up to 88% of its original capacity.
Another recent study highlights that battery costs could half by 2030. So, in the unlikely event that your battery does need to be replaced, it’d still be cheaper than when your car was new.
Many manufacturers in Australia, such as Tesla, offer an 8-year warranty on EV battery packs. This warranty also covers the drive unit and is more than what most manufacturers offer on engines of petrol or diesel cars.
