The invention provides an electric automobile power consumption controller and a control method, and relates to the technical field of electric automobiles. The automobile power consumption controllercomprises a constant electricity circuit module and a controllable circuit module which are connected with a power supply management module; the constant electricity circuit module comprises a communication circuit and a digital quantity input circuit and is used for supplying power to network communication of the whole vehicle and external signal detection of the whole vehicle; the controllablecircuit module comprises a power circuit and is used for supplying power to a vehicle lamp and a relay of the whole vehicle; and the power supply management module controls power distribution modes ofthe constant electricity circuit and the controllable circuit through an SPI communication protocol according to a wake-up signal, and the power distribution priority of the constant electricity circuit is higher than that of the controllable circuit. According to the electric automobile power consumption controller, a parking low-power-consumption scheme and a working low-power-consumption scheme can be realized by combining a control method.

    本发明提供了一种电动汽车功耗控制器及控制方法,涉及电动汽车技术领域,该汽车功耗控制器中包括分别与电源管理模块相连接的常电电路模块以及可控电路模块;常电电路模块包含通信电路以及数字量输入电路,用于向整车的网络通信以及整车外部信号检测进行供电;可控电路模块包含功率电路,用于向整车的车灯以及继电器进行供电;电源管理模块根据唤醒信号,通过SPI通信协议控制常电电路以及可控电路的配电方式,其中,常电电路的配电优先级高于可控电路。通过上述电动汽车功耗控制器,结合控制方法,可实现停车低功耗方案和工作低功耗方案。
