Abstract: Method and systems for determining a battery electric vehicle (BEV) protection plate has been damaged. A BEV protection plate includes a circuit. The circuit includes a plurality of conductive tabs. The BEV protection is separated from a battery housing by an opening. The conductive tabs extend from the circuit disposed on the BEV protection plate into the opening. A diagnostic device measures a voltage of the battery housing. A controller is in communication with the diagnostic device, determines a short circuit based on the measured voltage of the battery housing; and outputs to a display a notification that the BEV protection plate is compromised.

Abstract: An energy storage system includes a vehicle and a battery pack disposed within the vehicle. The battery pack includes a number of battery cells and a housing surrounding the battery cells. The housing includes an upper housing cover, a lower housing cover, an end plate, and a side frame coupled to the upper housing cover by an upper sealing flange of the side frame, and coupled to the lower housing cover by a lower sealing flange of the side frame. A majority of the volume of the end plate fits within a recess of the side frame, such that a majority of the volume of the side frame, upper sealing flange, lower sealing flange, and end plate is stacked vertically.
