Nissan EV batteries can be charged in two ways. When you decelerate while driving, the battery may be recharged somewhat through regenerating braking. This means that the kinetic energy produced by the brakes is turned into energy for the battery. The majority of the power for your EV’s battery will come from a power outlet or wall unit at home. A 110-volt household power outlet can be used, or you can upgrade to a 240-volt wall-charging unit. While you are out, you can recharge your battery at a public charging station.
