摘要： A charging system for direct current (DC) charging of a traction battery of an electric vehicle includes a stationary charging station and a portable module. The stationary charging station is connectable to a three-phase alternating current (AC) power supply operable for supplying first, second, and third phases of AC current. The stationary charging station has second and third AC/DC converters for the second and third phases of AC current, respectively. The portable module is removably connectable to the stationary charging station. The portable module has a first AC/DC converter for the first phase of AC current.
