Abstract
A method for managing the temperature of a battery of an electric or hybrid vehicle includes recording a temperature value at which the cooling or heating of the battery is triggered. The method further includes, for two consecutive values in a predefined sequence of states of charge: a step of comparing a real gradient to a reference gradient of the battery temperature; and a step of modifying, depending on the comparison, the value of the trigger temperature, or the value of the power output by cooling or heating the battery; and also includes applying the modified trigger temperature or output power for the following two consecutive values of the state of charge of the battery in the predefined sequence.
