Abstract

Methods for managing the heat in an electric battery, including, when recharging said battery, preconditioning at an average temperature T₀ and, when using said battery, determining the difference ΔT₁ between the temperatures of the hottest element and of the coolest element and as the absolute value ΔT₂ of the difference between the temperature T₀ and the average temperature T of said battery. The method includes, when the difference ΔT₁ is lower than a first setpoint C₁, deactivating the circulating device and as the heat-conditioning devices and, when the difference ΔT₁ is higher than a first setpoint C₁ or when the difference ΔT₂ is higher than a second setpoint C₂, activating the fluid-circulating device while keeping the heat-conditioning devices deactivated if the difference ΔT₂ is lower than the second setpoint C₂, or while activating a heat-conditioning device if the difference ΔT₂ is higher than the second setpoint C₂.
