The invention provides a vehicle-mounted direct current control system which is characterized in that an original vehicle generator charges a starting battery pack, the starting battery pack is connected with a life battery pack through a bidirectional double-battery manager, the starting battery pack charges the life battery pack through the bidirectional double-battery manager, and the life battery pack reversely charges the starting battery pack through the bidirectional double-battery manager; the output voltage of the second generator is the same as the voltage of the life battery pack, the life battery pack is charged by the second generator, the life battery pack is connected with the charging and inversion all-in-one machine, the charging and inversion all-in-one machine is connected with the mains supply interface, the life battery pack is used for supplying power to the direct-current electric appliance, and the charging and inversion all-in-one machine is used for supplying power to the alternating-current electric appliance. The problems that a product and a wire are heated due to large current, the system conversion efficiency is low, the time for charging a living battery is prolonged in the vehicle running process, the living battery is not easy to fully charge, and the battery feed is started due to the fact that the vehicle is idle for a long time in an existing recreational vehicle voltage platform are solved.

    本发明提供一种车载直流控制系统,原车发电机给启动电池组充电,启动电池组通过双向双电池管理器与生活电池组连接,启动电池组通过双向双电池管理器给生活电池组充电,生活电池组通过双向双电池管理器反向给启动电池组充电,第二发电机的输出电压与生活电池组的电压相同,第二发电机给生活电池组充电,生活电池组与充逆变一体机连接,充逆变一体机与市电接口连接,生活电池组用于给直流用电器供电,充逆变一体机用于给交流用电器供电。本发明解决了现有房车电压平台存在的电流大导致产品和导线发热,系统转换效率低,车辆行驶过程中给生活电池充电的时间加长,生活电池不容易充满,及车辆长时间闲置会导致启动电池馈电问题。
