Abstract
A thermal runaway protection method reduces thermal runaway for a battery pack. The battery pack includes: a housing defining a chamber; a cell group located in the chamber and having a pressure relief side; and a cooling component integrated into the housing and configured to cool the cell group in case of a temperature of at least part of the cell group higher than a preset temperature. The pressure relief side is spaced apart from an inner wall of the chamber to define an exhaust passage therebetween, and the exhaust passage is adapted to discharge gas generated by the cell group in case of thermal runaway of the cell group.
