Charger i.e. direct current/direct current converter, for e.g. hybrid vehicle, has traction network-sided rectifier formed as inverter, where energy of traction battery is transferable via rectifier, transformer and onboard rectifier

摘要

The charger (30) has an onboard network (20) connectable to an onboard network-sided rectifier with a power supply battery (21). Electrical energy of an external voltage source e.g. alternating current voltage source, is transferable to a traction battery (11) via a network-sided inverter, a transformer and a traction network-sided rectifier. The traction network-sided rectifier is formed as an inverter, where electrical energy of the traction battery is transferable to the supply battery via the traction network-sided rectifier, the transformer and the onboard rectifier. An independent claim is also included for a method for transmission of electrical energy in electric or hybrid vehicles.
