How long does an EV battery last?

Just like laptops and mobile phones, the battery in an electric vehicle will deteriorate with use. This deterioration means the vehicle's range will decline, lessening the amount of miles it can do between charges.

However, the lifespan of a battery can be lengthened and we are going to discuss how long it can last in this article.

How long do they last?

Despite common myths, EV batteries are often warranted for 8 years or 100,000 miles, as is the case with Nissan and Tesla. It is expected that they may even last up to 200,000 miles and that the battery will likely outlast the car itself.

Each year, countries and car manufacturers are developing EV batteries to make them smaller, more efficient, and cost-effective.

What happens when they run out?

Even after the battery has achieved 200,000 miles, it can still have a second life. They can be the perfect addition to renewable energy sources such as solar panels.

Toyota is said to be installing used batteries around convenience stores in Japan to store solar power.

How can you make the battery last longer?

  • Avoid letting your battery level fall below 20%

  • Similarly, avoid always charging your EV to 100% (opt for 80% instead)

  • Constantly using DC chargers can reduce battery lifespan

  • Charge your charge when temperatures are lower

  • Try to avoid extreme temperatures

  • Use your car immediately after charging if possible

  • Hard acceleration and braking will decrease battery life
