A METHOD FOR MANAGEMENT OF AN ENERGY STORAGE SYSTEM OF A VEHICLE

The invention relates to a method for determining an operational parameter indicative of the power capability of an energy storage system (ESS) of a vehicle, wherein the method comprises the steps of determining a state temperature of the ESS; determining an acceptable temperature increase of the ESS for a given time period based on the determined state temperature of the ESS and a maximum temperature threshold of ESS, the maximum temperature threshold being indicative of any one of a safety temperature level of the ESS and an operational life time temperature level of the ESS; and determining a maximum operational power level of the ESS for the given time period based on the determined acceptable temperature increase of the ESS.
