Electric vehicles are becoming increasingly popular as they reduce greenhouse gas emissions and noise pollution compared to cars that run on fossil fuels. But how long do electric vehicle batteries last? In general, electric vehicle batteries last 10 to 20 years, but some factors can reduce their lifespan. Heat, for example, is not a friend of electric vehicles and can cause batteries to degrade faster. When electric vehicle batteries reach the end of their useful life, they can be recycled.
In the U.S., most electric vehicle suppliers can reuse batteries for a second or third time after the typical 8- to 10-year battery warranty expires. On average, electric vehicle batteries only degrade at a rate of 2.3% of their maximum capacity per year, so with proper care, you can reliably expect your electric vehicle battery to last as long or longer than the components of the ICE transmission. The utility of this second-stage electric vehicle battery, when combined with renewable energy, means that people can save on bills and increase the use of clean energy. Nissan uses retired electric vehicle batteries to provide backup power to the Amsterdam Arena, the entertainment center and headquarters of Ajax Football Club.
Renault has also announced that the batteries for electric vehicles in the Renault Zoe EV will be reused to generate energy for the Powervault, a domestic energy battery storage system.If you have solar panels, you can further reduce your costs and power your car with renewable energy, reducing your total emissions. With the right maintenance and charging habits for
electric vehicles, you can significantly extend the battery life of your electric vehicle. The lithium-ion battery that charges your electric vehicle has a higher energy density than options such as lead-acid, so it takes up less space.All electric vehicle batteries will degrade over time, but the general consensus is that they should last 10 to 20 years before needing to be replaced. Some vehicles, such as the Hyundai Kona EV, come with a lifetime battery warranty in the event of a battery failure, but battery degradation is only covered for up to three years.In a virtuous energy cycle, eventually the factories that produce batteries could run on reused batteries.
There are many options for reusing electric vehicle batteries once they are no longer suitable for powering a car, such as using them to store energy at home.
