Electric Car Batteries: Lasting for 20 Years or More?

Many believe that electric vehicle (EV) batteries need frequent replacements, just like internal combustion engine (ICE) vehicles. However, this belief is a common misconception. Did you know that electric car batteries can last for 20 years or more, far exceeding the lifecycle of many ICE vehicles?

Longevity of EV Batteries vs ICE Cars

The lifespan of EV batteries varies depending on the manufacturer and model. Tesla, for instance, offers warranties of 150,000 miles for the Y model and 300,000 miles for the older Model S. These warranties are backed by extensive testing and real-world usage, indicating that properly maintained EVs can last for decades without needing battery replacements.

Compared to ICE vehicles, EVs require much less maintenance in terms of components. There are fewer moving parts, and most of the maintenance usually revolves around basic tasks like tire replacement and fluid management. This contrasts sharply with the frequent oil changes, tune-ups, and other service requirements of ICE vehicles.

Real-World Example: A 10-Year-Old Nissan Leaf

I recently acquired a first-generation 24 kWh Nissan Leaf that has been driven for 175,000 kilometers. Despite losing about a third of its original 175 km range, it still has sufficient range for my daily 20-35 km commute. In another 10 years, it will still be suitable for multiple short trips and daily use.

Adapting to Batteries

The battery in my Nissan Leaf is of an earlier model, which didn't always have the best thermal management. As battery technology has improved, newer models like the Nissan Leaf equipped with 30 kWh, 40 kWh, or 62 kWh batteries can be retrofitted into older vehicles. For example, a 1/2 capacity 62 kWh battery could be converted into a 31 kWh battery, providing an additional 25 km in range. This means my current Leaf could potentially have a range of 200 km.

Many owners of small, older EVs find that these vehicles are perfectly adequate for their daily needs, especially for around-town driving and short trips to work, shopping, and school runs. A 15-year-old Tesla with appropriate battery management and a modest 280 km range (and even better if you add 70 km) could easily replace an aging ICE car.

Cost Efficiency and Maintenance

Thanks to my background in automotive repair and my own experience maintaining cars, I can confirm that the cost and effort involved in maintaining an EV are much lower than those of an ICE vehicle. For me, it's down to tires and wiper fluid. No more dealing with the "filth" and constant maintenance of an ICE car.

Many people hang on to their smaller, older EVs for their precise needs, even if they see newer models with improved battery technology. It's a cost-effective solution for short-range driving and daily use.

Conclusion

Electric car batteries are more durable and long-lasting than many people imagine. Proper maintenance and following the manufacturer's guidelines can significantly extend their lifespan, far surpassing that of traditional gasoline vehicles. With fewer components and less maintenance required, EVs offer a more efficient and sustainable mode of transportation in the long run.
