ACCUMULATOR BATTERY HEATING CIRCUIT Russian patent published in 2015 - IPC H01M10/42 

FIELD: electricity.

SUBSTANCE: battery heating circuit containing the switching unit, switching control unit, damping element R1, energy accumulation circuit, energy transfer and combining unit, meanwhile the energy accumulation circuit is hooked up to the battery and contains the current accumulation device L1 and the charge accumulation device C1; the damping device R1, the switching unit, the current accumulation device L1 and the charge accumulation device C1 are connected in series; the switching control unit is connected to the switching unit and is designed with a possibility of on-off control of the switching unit (1) for control the energy the between the battery and the energy accumulation circuit; meanwhile the energy transfer and combining unit is connected to the energy accumulation circuit and is designed with a possibility of energy transfer in the energy accumulation circuit to the energy accumulation element after switching on and consequent switching off of the switching unit, and further combination of the residual energy in the energy accumulation circuit with energy in the battery.

EFFECT: improved efficiency of battery charging/discharging, improved safety of battery heating and improved overall performance of heating circuit, possibility of energy re-use.
