Electric Car Battery Capacity Loss

Range test on cars with battery capacity loss.

Electric car battery capacity loss. Select car leasing analysed 64 electric cars released between 2012 and 2019 to determine if strides are being made by car manufacturers to improve the battery degradation rates of their vehicles. Like the engines in conventional vehicles the advanced batteries in evs are designed for a long life but will wear out eventually. Currently most manufacturers are offering 8 year 100 000 mile warranties for their batteries. State of charge battery management a very necessary feature of modern electric cars nevertheless leaves you with about 60 70 percent of the rated capacity to work with.

Electric vehicle battery lifespan. Extreme heat is the enemy of lithium ion chemistry which is why many electric cars come with liquid cooled battery packs. Nissan is providing additional battery capacity loss coverage for 5 years or 60 000. It s interesting to note that nissan initially figured the leaf would retain 80 percent capacity after five years and 70 percent after 10 years.

A largely level course was driven at 100 km h as measured by the leaf s onboard gps 62 mph.
