Abstract

The invention discloses an energy interaction system based on distributed mobile energy storage and a working method thereof. The system comprises an alternating current electric energy input unit, an electric energy distribution unit and a plurality of mobile energy storage units, the electric energy distribution unit is in two-way communication and power supply connection with each mobile energy storage unit, and when the electric energy distribution unit receives an interactive power supply request of one mobile energy storage unit, the electric energy distribution unit sends an interactive power supply control signal to the other mobile energy storage units according to a time sequence; the mobile energy storage unit is used for supplying power to the AC load, sending an interactive power supply request to the electric energy distribution unit when the electric quantity is lower than a preset value, and entering an interactive power supply state to supply power to the electric energy distribution unit after receiving a control signal of interactive power supply. According to the invention, energy interaction between any mobile energy storage units can be realized, so that the independent mobile energy storage units form a power supply network to improve the reliability and stability of field power supply guarantee.

Description

technical field [0001] The invention relates to the technical field of power supply and distribution, in particular to an energy interaction system based on distributed mobile energy storage and a working method thereof. Background technique [0002] The mobile energy storage unit is a kind of portable energy storage unit, which can store electric energy by itself, and is used to charge or provide electric energy for mobile devices and other electronic products (such as flashlights, wireless phones, notebook computers), especially for occasions where there is no external power supply. Field work such as emergency rescue and disaster relief. [0003] In actual use, in order to ensure sufficient power, it is often necessary to equip multiple mobile energy storage units. The mobile energy storage units in the prior art basically adopt an independent power supply mode, that is, each mobile energy storage unit supplies power independently. When the power of one of the mobile ene...
