Abstract

The present invention discloses an on-board integrated charging device and a current distribution calculating method thereof. The on-board integrated charging device comprises a voltage conversion module. The voltage conversion module is provided with an AC terminal connected to an alternating current or an alternating current load, an HV terminal connected to a power battery and an LV terminal connected to a direct current load. When the AC terminal is idle, the LV terminal is powered by the HV terminal, and an input current of the LV terminal is an actual current of the HV terminal. According to the on-board integrated charging device, OBC, DCAC and DCDC functions can be integrated on the same circuit board, a current reporting requirement can be realized through a distribution algorithm, and the volume and weight of the whole device can be reduced.
