Abstract

The invention discloses a circulating battery for a distributed energy exchange system. The circulating battery comprises a plurality of battery cell bodies, and the battery cell bodies are electrically connected with an active equalization system and an AC / DC active arc extinguishing system; the active equalization system comprises a microprocessor unit, equalization control units, an equalization protection unit and a data acquisition circuit, wherein the data acquisition circuit, the equalization control units and the equalization protection unit are respectively connected with the microprocessor unit; the number of the equalization control units is equal to that of the battery cell bodies; and the equalization control units are connected with the battery cell bodies in parallel in a one-to-one correspondence manner. The system has the advantages that the safety of the circulating battery in the using process, especially in the charging process, is guaranteed; risks such as ignitionand explosion are avoided all the time; the loss of electric energy is greatly reduced through intelligent management in the charging process; and the most important characteristic is that a user canfreely assemble the battery for charging or using conveniently without waiting for charging.

Description

technical field [0001] The invention relates to the technical field of distributed energy exchange systems, in particular to a flow battery used in distributed energy exchange systems. Background technique [0002] In the existing technology, the distributed energy system is compared with the traditional centralized energy supply energy system. The traditional centralized energy supply system uses large-capacity equipment, centralized production, and then passes through special transmission facilities (large power grid, large heating network) etc.) to transmit various energies to many users in a large range; while the distributed energy system is directly oriented to users, produces and supplies energy on the spot according to the needs of users, has multiple functions, and can meet multiple goals. Small energy conversion and utilization system. [0003] At the same time, the space between the new energy vehicle and the energy storage cabinet in the prior art is also the pa...
