Abstract

An electric drive system includes a rechargeable battery and a power supply bus. A first power converter circuit is coupled between the rechargeable battery and the power supply bus. A motor is configured to be coupled to the power supply bus. A control circuit is configured to operate the first power converter circuit in one of a power supply mode in which the first power converter circuit supplies at least one of an alternating current and a rectified alternating current to the power supply bus, and a battery charging mode in which the first power converter circuit charges the rechargeable battery.

Description

technical field [0001] Embodiments of the invention relate to an electric drive system, in particular implemented in a vehicle. Background technique [0002] With increasing interest in sustainable energy production, electric vehicles such as electrically driven cars or motorcycles, which include a drive system with a rechargeable battery and an electric motor powered by the battery, are in the spotlight. In a conventional electric vehicle, the battery supplies DC (direct current) power to the inverter, which generates AC (alternating current) power from this DC power, and the asynchronous motor receives this AC power. Other loads such as air conditioning systems, motors for seat adjustment, window regulators etc., audio and navigation systems can also be additionally connected to the battery. [0003] Conventionally, there are cables in the vehicle from the battery to the individual loads. The battery DC voltage is, for example, about 400V in a car and between 600V and 80...
