The invention relates to the field of engineering machinery, and discloses a power supply device and a power supply method.The power supply device is applied to a crane, the crane comprises an engine and arm head sensing equipment, and the power supply device comprises a battery assembly, a cable assembly and a control module; when the voltage of the battery assembly is smaller than the preset rated voltage, the control cable assembly supplies power to the battery assembly and the arm head sensing equipment; and when it is determined that the engine is in a shutdown state and the voltage of the battery assembly is larger than or equal to the preset rated voltage, the cable assembly is controlled to be disconnected to supply power to the battery assembly, and the battery assembly is controlled to supply power to the arm head sensing equipment. According to the power supply device, the problem that the crane needs to stop halfway due to the power supply problem of the arm head sensing equipment can be avoided, so that the crane can continuously work for a long time, and the working efficiency is greatly improved.

    本发明涉及工程机械领域,公开了一种供电装置和供电方法,供电装置应用于起重机,起重机包括发动机和臂头感知设备,供电装置包括电池组件、电缆组件以及控制模块,控制模块被配置为:确定发动机处于运行状态,且电池组件的电压小于预设额定电压时,控制电缆组件为电池组件和臂头感知设备供电;确定发动机处于停机状态,且电池组件的电压大于或等于预设额定电压时,控制电缆组件断开为电池组件供电,并控制电池组件为臂头感知设备供电。本发明的供电装置可避免由于臂头感知设备的供电问题导致起重机需中途停机的问题,使起重机能够较长时间地持续作业,作业效率得到较大的提高。
