The invention provides a dual-power online power supply and charging system and a control method. A battery module receives or releases electric energy and supplies power to an advancing motor module; a vehicle-mounted charger module is connected to an external power supply and supplies power to an operation motor module; and the output voltage of the battery module is converted through the voltage conversion module and then is supplied to the operation motor module, the input voltage of the voltage conversion module is converted and then is supplied to the advancing motor module, and the input voltage of the voltage conversion module is converted and then is charged to the battery module. Therefore, the charging and discharging current of the battery module can be controlled, and the charging and discharging times of the battery module are reduced; when the operation motor module suddenly stops rotating, the input current of the battery can be subjected to voltage conversion through the voltage conversion module so that the safety of the battery is protected; and meanwhile, the requirement for the capacity of the battery module is low, and the cost of the whole system is greatly reduced.
本申请提供一种双动力在线供电充电系统及控制方法,通过电池模块接收或释放电能以及向行进电机模块供电;通过车载充电机模块接入外部电源并向作业电机模块供电;通过电压变换模块对电池模块的输出电压进行电压变换后向作业电机模块供电,对电压变换模块的输入电压进行电压变换后向行进电机模块供电,对电压变换模块的输入电压进行电压变换后向电池模块充电,从而能够控制电池模块充放电的电流大小,减少电池模块的充放电次数;当作业电机模块突然停转时,能够通过电压变换模块对电池的输入电流进行电压变换,保护电池安全;同时对电池模块的容量要求较低,大大降低整个系统的成本。
