<p>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 inductive charging coils (160), piezoelectric and Peltier devices (300), may also be used as emergency energy discharge loads. Heat absorption material (163) may be used to protect adjacent issue in medically-implanted devices.</p> |
