The invention discloses a conversion power supply control method of a vehicle-mounted direct current converter and an automobile. The method comprises the steps that a low-voltage storage battery supplies power to a vehicle-mounted low-voltage load; the vehicle-mounted direct-current converter is used for converting the power battery and then charging the low-voltage storage battery; after the vehicle is started, the electric quantity of a low-voltage storage battery and the power needed by a low-voltage load are collected in real time; the working state of the vehicle-mounted direct-current converter is controlled based on a circuit of a low-voltage storage battery and power required by a low-voltage load, and the low-voltage storage battery is adopted to provide required power consumption for the vehicle-mounted low-voltage load. Low-voltage power supply is carried out through the direct-current storage battery, meanwhile, the high efficiency of low-voltage power supply is improved by controlling the working time of the vehicle-mounted converter, and energy loss in the power supply process is reduced.

    本发明公开了一种车载直流转换器的转换供电控制方法及汽车,方法包括:低压蓄电池为车载低压负载供电;车载直流转换器用于将动力电池转换后为低压蓄电池充电;在车辆启动后,实时采集低压蓄电池的电量以及低压负载所需功率;基于低压蓄电池的电路及低压负载所需功率来控制车载直流转换器的工作状态,采用低压蓄电池为车载低压负载提供所需功耗。通过直流蓄电池进行低压供电,同时通过控制车载转换器的工作时机来提高低压供电的高效率,减少供电过程中的能量损耗。
