Abstract

A high-voltage charge booster is provided for charging a direct current traction battery at a direct current charging pillar. The high-voltage charge booster has a converter (14) for transforming the first voltage level into the second voltage level if the first voltage level differs from the second voltage level. A bypass (16) bypasses the converter (14) or connects through a power stage if the first voltage level corresponds to the second voltage level.
