The invention relates to the technical field of engineering machinery, and discloses an electric engineering machinery power supply system, method, medium and product, the system comprises a first engineering machinery and a second engineering machinery, the first engineering machinery and the second engineering machinery each comprise a power battery, a direct current charging interface, an electricity load and a power distribution system, and the first engineering machinery and the second engineering machinery are electrically connected through a direct current wire harness; the first engineering machinery outputs direct current to the power distribution system of the power supply side through the power battery of the power supply side, and outputs direct current to the direct current charging interface of the power supply side through the power distribution system of the power supply side, so that the direct current is transmitted to the direct current charging interface of the operation side through the direct current wire harness; and the second engineering machinery receives the direct current output by the first engineering machinery through the direct current charging interface on the operation side and transfers the direct current to the power distribution system on the operation side, and the power distribution system on the operation side transmits the received direct current to the electric load on the operation side for engineering operation. According to the invention, the convenience of long-time operation power supply of the electric engineering machinery is improved.

    本发明涉及工程机械技术领域,公开了一种电动工程机械供电系统、方法、介质和产品,系统包括第一工程机械和第二工程机械,第一工程机械和第二工程机械均包括动力电池、直流充电接口、用电负载和配电系统,并通过直流线束电性连接;第一工程机械通过供电侧的动力电池输出直流电到供电侧的配电系统,并通过供电侧的配电系统输出直流电到供电侧的直流充电接口,以使直流电通过直流线束传输到作业侧的直流充电接口;第二工程机械通过作业侧的直流充电接口接收第一工程机械输出的直流电,并将直流电流转到作业侧的配电系统,作业侧的配电系统将收到的直流电输送给作业侧的用电负载进行工程作业。本发明提高了电动工程机械长时间作业供电的便利性。
