Abstract: A method, device and system is disclosed for rapidly and safely discharging remaining energy stored in an electrochemical battery 104 in the event of an internal short circuit or other fault. In its best mode of implementation, if a sensor 116 detects one or more parameters such as battery temperature 204 or pressure 206, exceeding a predetermined threshold value 334, the terminals 144 of the battery or cell are intentionally short-circuited external to the battery through a low or near zero resistance load 150 which rapidly drains energy from the battery 104. The rate energy is drained via the external discharge load 150 may be controlled with an electronic circuit 136 responsive to factors such as state of charge and battery temperature. Devices such as piezoelectric and Peltier devices 300, may also be used as emergency energy discharge loads.
