Beschreibung
Zusammenfassung:	The invention discloses a vehicle-mounted charger for an electric vehicle, and belongs to the field of electric vehicle chargers. The invention aims at the problems that: an existing vehicle-mounted charger is single in working mode and cannot meet the requirements of charging, motor driving and diversified charging of an electric vehicle. An alternating current input circuit is connected with a primary side circuit, the primary side circuit is connected with a primary side coil of a transformer, a secondary side coil of the transformer is connected with a high-voltage battery pack through a secondary side circuit, a first mode switch K1 is arranged between the alternating current input circuit and the primary side circuit, and the motor is connected between the first mode switch K1 and the primary side circuit through a second mode switch K2. According to the invention, two working modes of charging and driving can be realized, and the requirement of diversity of the charging modes of the electric vehicle is
