Abstract

A switchable connection for a plurality of unit batteries for an electric vehicle. The unit batteries are normally connected in series through battery switches. When an impact sensor attached to a vehicle body detects an impact, a controller changes the battery switches to have a connecting state in which the unit batteries are separated into several groups.
