RAPID CHARGING DEVICE AND ELECTRIC DRIVE SYSTEM COMPRISING A RAPID CHARGING DEVICE OF SAID TYPE

摘要

The invention relates to a charging device for charging a battery (7) of a motor vehicle fitted with an electric drive motor (2), having an inductance, and a drive converter (3) which converts the direct voltage of the battery (7) for the electric drive motor (2) when the motor vehicle is being driven. The inductance, together with the drive converter (3), is used as a step-up converter for charging the battery (7). The aim of providing an improved and, in particular, more adaptable charging device, is achieved by providing a switching unit (10) in the charging device, said switching unit being designed to connect a charge source (8, 12) to the battery (7) directly or via the step-up converter.
