The invention provides an online power supply and charging system and a control method. A vehicle-mounted charger module is connected to an external power supply and supplies power to a motor module; the electric connection between the battery module and the motor module is switched on or switched off through a switch module, and the electric connection between the vehicle-mounted charger module and the battery module is switched on or switched off through the switch module; a voltage conversion module performs voltage conversion on the output voltage of the battery module and then supplies power to the motor module, and performs voltage conversion on the input voltage of the voltage conversion module and then charges the battery module, so that 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 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.

    本申请提供一种在线供电充电系统及控制方法,通过车载充电机模块接入外部电源并向电机模块供电;通过开关模块接通或断开电池模块与电机模块之间的电连接,以及接通或断开车载充电机模块与电池模块之间的电连接;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电机模块供电,以及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。
