Article Source：Kinri Energy | Author：Kinri Energy | Issuing Time：2024.04.12
On April 12, 2024, the financial sector reported that according to the announcement of the China National Intellectual Property Administration, SUNGROW Co., Ltd. applied for a patent entitled "charging power distribution circuit, charging control method and charging pile", with the publication number of CN117879096A, and the application date of December 2023.



The patent abstract shows that the present application discloses a charging power distribution circuit, a charging control method, and a charging pile, belonging to the field of power management technology. This application provides a charging power distribution circuit with multiple charging circuits configured to provide charging current; Multiple first switches, the first switch is electrically connected between two charging circuits; Among them, one charging circuit and the charging circuit directly connected through the first switch serve as the charging circuit group, and there is at least one charging circuit outside the charging circuit group between adjacent charging circuits in the charging circuit group. Any charging circuit is connected to other charging circuits in a staggered manner through at least one first switch. When the independent power supply of the charging circuit cannot meet the charging demand, the first switch can be controlled to conduct and connect to other charging circuits for common power supply. When there are multiple charging circuits, it can not only improve the utilization rate of the power module, but also significantly reduce the number of switches, thereby reducing the space occupied by the switch layout.
