The invention relates to the technical field of motor homes, in particular to a motor home vehicle-mounted power supply system. A motor home vehicle-mounted power supply system is characterized in that a motor home comprises an original vehicle system and electric equipment, the motor home vehicle-mounted power supply system is charged through external power supply equipment, the external power supply equipment comprises a new energy vehicle direct current charging pile, and the motor home vehicle-mounted power supply system comprises a high-voltage battery pack; a DCDC converter; an OBC vehicle-mounted charger; wherein the high-voltage battery pack is respectively connected with the DCDC converter and the OBC vehicle-mounted charger; direct current output by the new energy automobile direct current charging pile directly charges the high-voltage battery pack; direct current output by the high-voltage battery pack is converted into direct current with different voltages through the DCDC converter to supply power to direct current electric equipment; and direct current output by the high-voltage battery pack is converted into alternating current through the OBC vehicle-mounted charger to supply power to alternating current electric equipment. The electric energy capacity of the motor home is obviously improved, and the quick charging function is achieved.

    本发明涉及房车技术领域,特别是涉及一种房车车载电源系统。一种房车车载电源系统,所述房车包括原车系统及用电设备,所述房车车载电源系统通过外部供电设备充电,所述外部供电设备包括新能源汽车直流充电桩,所述房车车载电源系统包括:高压电池包;DCDC转换器;OBC车载充电机;其中,所述高压电池包分别与所述DCDC转换器及所述OBC车载充电机连接;所述新能源汽车直流充电桩输出的直流电直接为所述高压电池包充电;所述高压电池包输出的直流电经所述DCDC转换器转换为不同电压的直流电,为直流用电设备供电;所述高压电池包输出的直流电经所述OBC车载充电机转换为交流电,为交流用电设备供电。实现了房车电能容量的明显提升及快充功能。
