Abstract
Abstract An electric vehicle power distribution module including a chassis containing electric power distribution components. A battery connector is disposed on the chassis for electrically connecting the power distribution components to a battery. A safety cover is secured to the chassis and includes an aperature in a side wall for receiving an electric cable from the battery to be selectively engaged with the battery connector. The aperture is positioned with respect to the battery connector so as to preclude removal of the safety cover from the chassis without disengagement of the electric cable from the battery connector.
