A high-temperature battery for the power supply of electrically powered vehicles is disclosed which has a thermally insulating housing and a cooling system with a cooling body which is arranged inside the thermally insulating housing. Air or other fluid coolant flows through the cooling body and is supplied through an insulating wall of the housing solely by means of coolant inlet and air outlet connecting elements arranged on the housing. The cooling body is formed by a parallel arrangement of plate-shaped cooling-body elements through which coolant flows and which are designed as hollow bodies. The bar-shaped battery cells are arranged in the space between the cooling-body elements. The coolant inlet and outlet are arranged at one side of the housing and are connected to inlet and outlet openings of the cooling-body elements so as to provide optimum cross-flow cooling power on the battery cells. Coolant in the form of air or oil can be used according to preferred embodiments.
