摘要
A method and apparatus for deactivating a bad battery cell from a battery pack for an energy storage system of an electric vehicle is disclosed. The apparatus and methodology includes a clamshell member arranged at an end of the cells and a printed circuit board arranged adjacent to the clamshell member. A collector plate is arranged adjacent to the printed circuit board and a switch is arranged on the printed circuit board. A wire bond is arranged between the switch and one of the cells and a second wire bond is arranged between the switch and the collector plate. The plurality of switches will allow for the identification of the one individual cell having a weak short circuit within the battery pack. Upon identification of the cell with the weak short circuit that cell will have its switch placed in an open position thus electrically isolating the faulty or bad cell from the battery pack.
