The invention provides a high-low voltage battery integrated control power supply system and method and an operation machine, and belongs to the technical field of power supply control. The system comprises an ignition switch module, a high-voltage battery pack, a low-voltage battery pack, a battery management module and a direct current conversion module; when the ignition switch module is closed, the battery management module determines a closed gear signal of the ignition switch module, and when the closed gear signal and the state parameters of the low-voltage battery pack indicate that the direct-current conversion module needs to be started, the battery management module starts the direct-current conversion module. The battery management module controls the direct-current conversion module to convert the voltage of the high-voltage battery pack into the target voltage to charge the low-voltage battery pack, and the battery management module determines that the direct-current conversion module is in a working state only when the direct-current conversion module needs to be started according to the electricity demand of the ignition switch and the state parameters of the low-voltage battery pack. Otherwise, the direct current conversion module is kept in a dormant state, so that the energy consumption waste is effectively reduced, and the energy is saved.
本发明提供一种高低压电池集成控制供电系统、方法及作业机械,属于供电控制技术领域,系统包括点火开关模块、高压电池组、低压电池组、电池管理模块和直流转换模块;当点火开关模块闭合时,电池管理模块确定点火开关模块的闭合档位信号,当闭合档位信号和低压电池组的状态参数表示需要启动直流转换模块时,电池管理模块控制直流转换模块将高压电池组的电压转换为目标电压为低压电池组进行充电,电池管理模块根据点火开关的用电需求以及低压电池组的状态参数,确定需求启动直流转换模块时,直流转换模块才会处于工作状态,进行电压转换,否则,保持直流转换模块处于休眠状态,从而有效地降低了能耗浪费,节约了能源。
