The embodiment of the invention discloses a control method and device for the output voltage of a direct-current converter and a vehicle control unit. The control method for the output voltage of the direct-current converter comprises the steps that after the electric vehicle is powered on, the current storage battery voltage value and the current storage battery electric quantity value corresponding to a storage battery of the electric vehicle are obtained, a power utilization state of whole-vehicle electric appliances in the electric vehicle is detected, and the whole-vehicle electric appliances comprise the first electric appliance and the second electric appliance; and a direct current converter is controlled to output a first target voltage value or a second target voltage value according to the current storage battery voltage value, the current storage battery electric quantity value and the power utilization state. According to the control method, energy consumption of the electric appliance for the vehicle is reduced, and the endurance mileage of the electric vehicle is increased.

    本发明实施例公开了一种直流变换器输出电压的控制方法、装置及整车控制器。该直流变换器输出电压的控制方法包括:在电动车辆上电后,获取所述电动车辆的蓄电池对应的当前蓄电池电压值和当前蓄电池电量值,并检测所述电动车辆中整车用电器的用电状态,所述整车用电器包括第一用电器和第二用电器;根据所述当前蓄电池电压值、所述当前蓄电池电量值和所述用电状态控制直流变换器输出第一目标电压值或第二目标电压值。本发明实施例的技术方案,以实现降低车用用电器能耗,提高电动车辆续航里程。
