ACCUMULATOR BATTERY HEATING CIRCUIT Russian patent published in 2014 - IPC H01M10/42 

FIELD: electricity.

SUBSTANCE: accumulator battery heating circuit includes a switching unit, a switching control module, a damping element R1, energy storage circuit and energy transmission unit, at that the energy storage circuit is coupled to the accumulator battery and comprises a current accumulating element L1 and charge accumulating element C1; the damping element R1 and switching unit are connected in series with the energy storage circuit; the switching control module (100) is coupled to the switching unit and is designed to control switching on/off of the switching unit in order to control energy passage between the accumulator battery and energy storage circuit; moreover the energy transmission unit is coupled to the energy storage circuit and is made to transmit energy from the energy storage circuit to the energy accumulating element upon switching on/off of the switching unit.

EFFECT: improving efficiency of the accumulator battery charge and discharge, safety at the accumulator battery heating and providing function of energy re-use.
