Abstract: A method for controlling cooling of a traction battery in an electric vehicle where the method comprises determining a battery temperature profile for a segment of a planned route based on route information describing a route from a starting point to a destination and based on a current battery status and determining a battery cooling profile for the segment of the route based on the battery temperature profile. By means of the route information and the state of the battery, the battery cooling profile can be determined in order to minimize the power required for cooling the battery. Since the route information can provide information relating to a range of parameters which influence the power consumption along the route, the cooling needs of the battery can also be estimated for the route as a whole.
