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.

Claim (Index 17):
The method of  claim 16 , wherein the instantaneous heat release power  x  satisfies a fourth formula: Q x = \u0394 \ue89e \ue89e H x \u00b7 m x \u00b7 dc x dt wherein \u0394H x  represents a total energy release of unit mass of the testing component material corresponding to a thermal runaway reaction x; m x  represents a mass of the testing component material; and dc x dt represents a reaction rate of the testing component material;\n wherein the reaction rate satisfies a fifth formula: \n dc x dt = A x \u00b7 f \ue8a0 ( c x ) \u00b7 exp \ue8a0 ( - E a , x R \u00b7 T ) , ( T > T onset , x ) wherein c x  represents a normalized concentration of reaction materials of the testing component material of the first power battery or the second power battery; A x  represents a frequency factor; E a,x  represents an activation energy of the reaction kinetics; R represents an ideal gas constant and is equal to 8.314 J\u00b7mol \u22121 \u00b7K \u22121 ; T onset,x  represents an onset temperature of the thermal runaway reaction x, and f(c x ) represents a mode of the thermal runaway reaction x; wherein the mode f(c x ) satisfies a sixth formula:\n f ( c x )= c x P x \u00b7(1\u2212 c x ) q x \u00b7{ln (1\u2212 c x )} s x  \n wherein p x , q x , and s x  represents the order of the thermal runaway reaction x.
