An embodiment of the invention provides an automatic charging system for an engineering vehicle, and belongs to the field of vehicle power supply control. The automatic charging system comprises a power supply unit, a charging device and a control unit, wherein the power supply unit comprises a mains supply charging interface, a generator and an engine; and the control unit is used for determining a power supply for charging a storage battery of the engineering vehicle from the mains supply, the generator and the engine, and enabling the power supply to charge the storage battery through the charging device. According to the automatic charging system, on the basis that an original vehicle charging system is provided with a mains supply and an engine charging power supply, a charging power supply, namely the generator, is additionally arranged, and switching charging among the power supplies is controlled, so that on one hand, the phenomenon of storage battery feed can be avoided when system power equipment works, and on the other hand, the coordination work of commercial power charging, engine charging and generator charging is ensured.
本发明实施例提供一种用于工程车辆的自动充电系统,属于车辆供电控制领域。所述系统包括:供电单元、充电装置和控制单元,其中所述供电单元包括:市电充电接口、发电机和发动机;所述控制单元用于从市电、所述发电机和所述发动机中确定向工程车辆的电瓶充电的电源,并使所述电源通过所述充电装置向所述电瓶充电。该系统通过在原车辆充电系统配备有市电和发动机充电电源的基础上另外加入发电机这一充电电源,并控制各电源间的切换充电,一方面可以实现在系统动力设备工作时避免电瓶馈电现象的发生,另一方面保证市电充电、发动机充电和发电机充电三者协调工作。
