Article Source：Kinri Energy | Author：Kinri Energy | Issuing Time：2024.05.17
Securities Star News: According to data from Qichacha, SUNGROW (300274) has obtained a new invention patent authorization, titled "A Multi DC Coupling System and Its Control Method", with patent application number CN202110249203.4 and authorization date of May 14, 2024.

Patent Abstract: The present invention provides a multi DC coupling system and its control method. After receiving external scheduling instructions, the scheduling power is first evenly distributed based on the number of online DC coupling systems and sent to each DC coupling system as the initial given power to control each DC coupling system to operate according to the initial given power; Then, according to the preset balance strategy, determine the power regulation amount of each DC coupling system and send it to each DC coupling system, and then control each DC coupling system to operate according to the superposition result of their corresponding initial given power and power regulation amount; That is to say, by adjusting the output of each DC coupling system according to the preset balance strategy, the balance of each battery system is achieved, thereby solving the problem of large battery state deviation and inconsistent lifespan in multi DC coupling systems.
