摘要:
A DC voltage source, for example an AC/DC converter, has an output producing a controllable DC voltage for a DC charging station to charge the battery of an electric vehicle. A voltage balancing unit is connected between the output of the converter and the output terminal of the DC charging station. The voltage balancing unit has a controllable switch by which the connection between voltage source or converter and battery can be made or broken as desired. The switch is controlled as a function of the voltage on the input and output side of the voltage balancing unit to the effect that the switch breaks the connection before and while the battery is being connected to the DC output terminal, and makes a connection only when the voltage on the input side of the voltage balancing unit corresponds substantially to the voltage on the output side of the voltage balancing unit.
