what is the life of battery in electric vehicle

 life of EV BATTERY

Battery life is one of the biggest worries potential buyers have when considering an electric car. Along with range and the fear of running out of power mid-journey, known as range anxiety – the way an electric car’s battery might degrade over time is considered a big barrier to EV ownership.

Like any battery, including the one in your mobile phone or laptop, the batteries in electric cars will lose some of their capacity over extended use. Below, we’ve explained why this happens and offered advice on how you can keep your electric car battery in top condition for longer.

Car makers are well aware that potential buyers are concerned about the longevity of their car’s batteries, and many offer warranties tailored for EV owners. On the Leaf for example, Nissan offers a warranty covering the battery and electric motor for up to five years or 60,000 miles.

Elsewhere, Renault’s warranty covers the ZOE electric hatchback for up to 100,000 miles or three years while Tesla offers an eight-year warranty on the Model S that’s not subject to any mileage and can be transferred between owners.

According to the latest results from our Reliability Servey the Nissan Leaf is the most reliable electric car, with a score of 99.7% – with the few complaints we received being about the car’s bodywork, rather than its battery. At the other end of the scale is the Tesla Model S, with a score of 50.9%. Most of those faults were to do with its electrical systems and bodywork, however; just 4% of the complaints we received related to its battery.

It’s also worth noting that there are cases where an electric car battery has long since surpassed expectations. In 2015, for example, Nissan reported the case of a Leaf that was bought in 2013 to be used as a taxi around Cornwall. The car had covered more than 100,000 miles without losing any of its battery life.
