Abstract

The invention relates to a vanadium battery SOC balance system. The vanadium battery SOC balance system comprises a detection module, a control module, a load module and a plurality of vanadium battery modules; the plurality of vanadium battery modules are sequentially connected in series; the detection module is used for detecting SOC values of the plurality of vanadium battery modules and outputting the SOC values; and the control module is connected with the detection module and used for receiving the SOC values and connecting the load module to one of the vanadium battery modules according to the SOC values. The detection module can detect the SOC values of the plurality of vanadium battery modules, and the control module can access the load into one of the vanadium battery modules according to the SOC values, so that the vanadium battery module accessed into the load module can discharge through the load module, the SOC value of the vanadium battery module is further reduced, and the SOC values of the plurality of vanadium battery modules are balanced.

Description

technical field [0001] The present application relates to the field of vanadium batteries, in particular to a vanadium battery SOC balance system. Background technique [0002] A vanadium battery is a storage battery that can conserve energy by utilizing the different chemical potentials of vanadium ions in different oxidation states. Vanadium batteries have the advantages of high charge and discharge efficiency, and the electrolyte can be recycled. [0003] It can be understood that many battery stacks can be connected between a positive electrolyte tank and a negative electrolyte tank. All the battery stacks can be connected in series to increase the battery capacity, and all the battery stacks can be connected in parallel to increase the power. The re-parallel connection can form a battery with better performance, but it will make the pipeline loss larger, and at the same time, the pipeline current will increase, which will easily cause the stack to be damaged. However,...
