Method for optimized cooling of an electric or hybrid vehicle battery

Abstract

A method for cooling a battery of an electric or hybrid vehicle, including: determining a curve showing the theoretical thermal power dissipated by the battery as a function of time during continuous charging of the battery at maximum charging power, and of the battery charging duration, determining a maximum thermal power dissipated by the battery during charging, determining a maximum cooling power of a device for cooling the battery, determining a theoretical maximum temperature reached by the battery during charging at maximum charging power, comparing the maximum cooling power with the maximum thermal power dissipated by the battery, and then starting the charging of the battery and, as a function of comparison, imposing a cooling power on the cooling device at one or more successive levels decreasing over time.
