Abstract:
A method for forecasting thermal runaway safety of a full battery by a computer is provided and including receiving a self heat generation onset temperature T 0  of a first power battery, wherein the first power battery is a half cell; calculating a maximum temperature T max  of thermal runaway of the first power battery based on a thermal runaway reaction kinetic model stored in the computer, calculating a maximum temperature rise ΔT by making difference between the maximum temperature T max  and the self heat generation onset temperature T 0 ; and judging the thermal runaway safety of the first power battery by the relationship between the self heat generation onset temperature T 0  and the maximum temperature rise ΔT.
