METHOD AND APPARATUS OF HEATING FOR BATTERY

摘要

A method for heating a battery device having a plurality of battery cells, and an apparatus for heating a battery device are provided to improve the low temperature characteristics of a battery without using additional equipment and to allow the balancing of SOC and the heating of a battery to be carried out simultaneously. A method for heating a battery device comprises the steps of (200) sensing the temperature of a battery device; and (208) heating the battery device by carrying out a forcible discharge function for the balancing of SOC if the sensed temperature is determined to be below a certain temperature. Preferably the forcible discharge process is carried out by (204) measuring the SOC to the each battery cell; and (208) carrying out the forcible discharge if the SOC is above the preset discharge limit. Preferably the forcible discharge is carried out through a heat radiating element.
