Abstract
The invention relates to a method for managing the heat in an electric battery including a plurality of elements for generating electric power, the method including, when recharging said battery from an external power source, preconditioning said battery at an average temperature T0 and, when using said battery, determining the absolute value ΔT2 of the difference between the temperature T0 and the average temperature T of said battery, wherein said method includes activating a heat-conditioning device of the battery when the difference ΔT2 is higher than a setpoint C2, said setpoint being established on the basis of the state of charge (SOC) of said battery.
