Abstract:
A method and system for preventing battery thermal runaway are provided. The method includes: detecting or predicting whether there is a thermal runaway risk for each battery cell or battery module of a battery pack; and in response to detecting or predicting that there is a thermal runaway risk for at least one battery cell or battery module of the battery pack, transferring battery energy of the at least one battery cell or battery module to the battery pack or another battery pack as thermal energy or electric energy.
