3. On Board Charger & DC/DC Converter Combo
The integrated 2-in-1 OBC+DC/DC system consists of the on-board charger (OBC) and the DC-to-DC converter (DCDC). The OBC takes energy from the AC grid and converts it to high voltage DC to charge the vehicle’s power battery. The entire charging process of the vehicle can be monitored. At the same time, the OBC has the functions of inversion, achieving the transfer of energy from the power battery to the AC side. The on-board DC/DC converter converts the high-voltage DC to the required low-voltage DC, providing a low-voltage supply for the entire vehicle and charging the auxiliary battery. OBC and DC/DC report output voltage and current via the CAN bus, and achieve information exchange and operating status feedback with the BMS and VCU via CAN communication.
