  • Patent number: 10868318
    Abstract: A flow battery has a control system and a control method to control the operation of the flow battery. The control method includes disposing an SOC detection device respectively at a positive electrolyte outlet and a negative electrolyte outlet of a cell stack; obtaining, by the SOC detection devices, SOCs at the electrolyte outlets of the cell stack under an initial state of the flow battery; at every preset time, acquiring the volume of electrolyte in the positive electrolyte storage tank, the volume of electrolyte in the negative electrolyte storage tank, the volume of the electrolyte flowing into the positive electrolyte storage tank, and the volume of the electrolyte flowing into the negative electrolyte storage tank, and meanwhile, obtaining, by the SOC detection devices, SOCs at the electrolyte outlets of the cell stack; and obtaining SOC of the flow battery.

  • Publication number: 20190288320
    Abstract: The present disclosure discloses a flow battery system and a large-scale flow battery energy storage device. The flow battery system comprises multiple flow batteries; each of the flow batteries comprises a battery pack A, a battery pack B, a battery pack C, and a set of electrolyte circulation system used by the battery pack A, the battery pack B and the battery pack C; the battery pack A, the battery pack B and the battery pack C comprised in each flow battery are independent of each other in the circuit. According to the present disclosure, at least two sets of electrolyte circulation system are saved under the same power scale, such that the system stability is improved while the cost is reduced.

  • Publication number: 20190123369
    Abstract: The control method for a flow battery includes acquiring a current electrolyte capacity decay rate of the flow battery; comparing the current electrolyte capacity decay rate with a first preset decay rate and a second preset decay rate; when the current electrolyte capacity decay rate is greater than the first preset decay rate and less than the second preset decay rate, adjusting a liquid level of positive electrolyte and a liquid level of negative electrolyte, such that a difference between these two liquid levels is less than a preset value, a ratio of the total amount of vanadium in the positive electrolyte to the total amount of vanadium in the negative electrolyte remains in a first preset ratio range, or a ratio of a vanadium ion concentration in the positive electrolyte to a vanadium ion concentration in the negative electrolyte remains in a second preset ratio range.
