How much charge does an EV lose when it is not in use?

The rate of charge an EV loses – sometimes called vampire drain – will depend on a range of factors including the specific model, the age of the car, the frequency of use, the use of security features while parked such as 360-degree cameras, and the temperature of the battery.

Generally speaking, if left parked, an EV may lose a small percentage of charge each month, however, this is unlikely to have any major impact on the driving range. If EV owners are planning on leaving their car for an extended period of time, they should refer to their vehicle’s manual to understand the manufacturer’s specific recommendations, including whether to leave their vehicle plugged in.
