The invention relates to the technical field of vehicle charging, and provides an engineering machinery charging device and electric engineering machinery, and an engineering machinery power bank is configured by integrating a power battery, a high-voltage distribution box, a power supply distribution unit, an alternating current-direct current integrated charging seat, a vehicle-mounted charger, an inversion boosting assembly and a controller into a whole. Therefore, direct current can completely charge the power battery, alternating current can completely charge the power battery, part of the alternating current can be used for charging the power battery, and the rest of the alternating current can charge different industrial charging seats. Therefore, the power distribution quantity of the engineering machinery power bank is improved, a direct-current charging function, an alternating-current charging function and a charging and discharging function are realized, and a one-to-many charging function can be realized in a manner that alternating-current output is equipped with an industrial plug, so that the engineering machinery power bank is suitable for a severe charging environment of engineering machinery; and meanwhile, the flexibility and the easiness in implementation of industrial charging are also improved.

    本发明涉及车辆充电技术领域,提供一种工程机械充电装置及电动工程机械,通过动力电池、高压配电盒、电源分配单元、交直一体充电座、车载充电机、逆变升压组件和控制器集成为一体的方式配置工程机械充电宝,实现直流电全部为动力电池充电,以及交流电既能全部为动力电池充电,也能部分交流电用于动力电池充电、剩余部分交流电为不同工业充电座充电。这样,不仅提高了工程机械充电宝的配电量,实现了直流充电功能、交流充电功能和边充边放功能,也能通过交流输出配备工业插头的方式实现一对多充电功能,从而适用于工程机械恶劣的充电环境,同时也提高了工业充电的灵活性和易实现性。
