An example cooling system for an electric includes an electric motor having a supply opening for receiving coolant and a discharge opening for expelling coolant. The discharge opening is connected to the supply opening via a coolant circuit including a first return line in which a heat exchanger is arranged, a bypass line, and a second return line. The discharge opening is connected to the supply opening by both the first return line and the bypass line, and the bypass line bypasses the heat exchanger arranged in the first return line. A battery is arranged in the second return line, and the second return line is selectively connected to a short-circuit line which causes coolant to flow from a point downstream of the battery and return to the second return line upstream of the battery. Further, a heat accumulator is arranged in the short-circuit line.

Electric motor with cooling system and corresponding method

A exhaust-gas heat management system includes a catalytic converter in the exhaust-gas train of an internal-combustion engine, a cover enclosing the catalytic converter, and thereby realizing a cavity for holding a latent-heat storage PCM, at least two fluid connections between the cavity and the collecting vessel, and a pump device for activating and deactivating a PCM circuit between the cavity and the collecting vessel by means of the fluid connections. A method comprises determining an operating state of the internal combustion engine, determining the catalytic converter temperature, determining the PCM temperature, activating the PCM circuit if the PCM temperature is above a phase transition temperature of the PCM, and the internal combustion engine is in a switched-on operating state or the internal combustion engine is in a switched-off operating state and the catalytic converter temperature is below a light-off temperature of the catalytic converter.

Method and system for exhaust-gas heat management

A fuel cell system () comprises at least one fuel cell () and at least one gas generation system () in which at least one component requires air during operation. A compression device () is provided to supply the oxygen-containing gas, for example air, to the cathode chamber () of the fuel cell. At least one branch line () also supplies oxygen-containing gas to the gas generation system component(s) that requires air during operation thereof. Exhaust gases from the fuel cell cathode chamber anode chamber are combined downstream of the fuel cell.
