What does regenerative braking have to do with an EV’s battery?

EV batteries are charged by plugging the EV charger’s cord into the vehicle’s charging port. They can also gain charge from regenerative braking systems. “Regen” braking systems are unique to EVs. They turn a vehicle’s kinetic energy (energy that relates to motion) back into electric energy. This transformation occurs during braking, decelerating or coasting downhill. Plus, these systems also dramatically reduce wear and tear on a vehicle’s braking system
