The present disclosure provides an energy release device and method for a power battery. The energy release method for a power battery comprises: acquiring a thermal runaway signal of battery cells in the power battery; and electrically communicating the power battery with a discharge element, so that the power battery is discharged to a maximum safe state of charge that satisfies a mild exothermic reaction under the condition of thermal runaway, or a state of charge below the maximum safe state of charge, wherein satisfying the mild exothermic reaction is that the temperature per unit volume of the battery cells in the power battery under the condition of thermal runaway does not exceed the temperature at which the thermal runaway is triggered. According to the solution provided by the present disclosure, the development of thermal runaway in a power battery pack can be effectively delayed, time is bought for passenger escape and subsequent thermal runaway control processing, meanwhile, the destructive power of thermal runaway is reduced, and the safety management capability of the power battery is improved.
