If a pulse inverter does not work efficiently, valuable drive energy is lost in the form of heat. Since this heat must be dissipated, the cooling requirement increases which in turn increases the energy consumption of the cooling system.
For the first pulse inverter to be “designed by Volkswagen,” the developers of these core components redesigned the hardware and software from the ground up. Thanks to the modular toolkit principle, this can be implemented in everything from entry-level engines to sports cars with an output of over 500 kW and more in future.
The proposed strategy is applied to heating the battery at the different SOCs, and its performance is compared to the constant amplitude pulse. In the same heating time, the battery temperature achieved by the proposed strategy is at least 7.6 °C higher than the constant amplitude pulse.
