Existing fuel-powered generators need to continuously consume fuel during operation, and are prone to gas emissions that pollute the environment, making it difficult to meet the requirements of energy conservation and carbon reduction; moreover, fuel-powered generators are usually large and difficult to enter near some distribution rooms with narrow passages, making power supply wiring and other operations inconvenient.

[0003] The Chinese invention patent with the patent announcement number CN111055748A and the patent name A low-voltage mobile energy storage system and its control method discloses a low-voltage mobile energy storage system, including a docking box, connecting wires and an energy storage vehicle, the energy storage vehicle includes a PCS unit, a PCS controller and an energy storage unit, the PCS unit is connected to the energy storage unit, and the plug-in base is connected to the output end of the PCS unit. It adopts a mobile energy storage system, so that the energy storage device can be flexibly deployed in a variety of application scenarios, such as temporary power supply, emergency power supply and power protection, etc., to improve the efficiency of the energy storage device.
