Beijing Hongtong Weihe Technology Co., Ltd. has applied for a patent titled "Automatic Protection Method for Liquid Flow Battery Electrical Equipment", with publication number CN 119253800 A.

      The patent abstract shows that the present invention discloses a self-protection method for flow battery electrical equipment, comprising the following modules: temperature monitoring and heat dissipation module, current and voltage monitoring module, output monitoring and regulation module, circuit breaker, master-slave and interlock control module. The devices coordinate with each other through master-slave and interlocking mechanisms to ensure that they start in the predetermined order. When any device in the system malfunctions or runs abnormally, the system will issue an alarm. Based on the fault situation, the system will automatically adjust parameters or shut down to prevent the problem from escalating; The master-slave and interlocking control modules include inverters DCDC、 The monitoring and control system shall be started in the order mentioned above. This invention is a comprehensive security strategy aimed at improving the reliability and safety of the system through real-time monitoring and automatic control.

      Zhonghai Energy Storage Technology (Beijing) Co., Ltd. has applied for a patent titled "An Instant Response Iron Chromium Liquid Flow Battery Quantitative Rebalance System and Rebalance Method", with publication number CN 119252978 A.

     The patent abstract shows that the present invention relates to the field of iron chromium flow battery technology, and specifically discloses an instant response iron chromium flow battery quantitative rebalancing system and rebalancing method. The system includes an iron chromium flow battery stack, a positive electrode storage tank, a negative electrode storage tank, a control system, a sieve plate tower, an acid storage tank, a gas generator, a booster pump, an absorption tank, a cyclone separator, a filter, a rebalancing electrolyte storage tank, a solid recovery tank, and an air compressor. The sieve tray tower is the site where the rebalancing reaction occurs, and the gas generator is used to generate the rebalancing reactants, which are then pumped into the sieve tray tower through a booster pump; After the rebalancing is completed, the electrolyte is separated by a cyclone separator and a filter. The absorption tank can remove excess gas during the reaction process, and the absorption liquid can be regenerated and reused by introducing air through an air compressor. The system of the present invention can achieve immediate response after feeding, start the rebalancing reaction at any time, and quantitatively rebalance the excess trivalent iron ions in the positive electrode electrolyte. The process flow is simple and safe.
