Leoch provides safe lithium iron phosphate (LiFePO4) battery solutions for UPS and energy storage systems, combining excellent compatibility, safety, and long cycle life. This battery system utilizes a three-tier architecture: a battery pack-integrated module-level management system (BMU) collects cell voltage, module temperature, and cell balancing data, and communicates with upper-level management systems. A cabinet-level management system (CBMS) is responsible for battery current detection, data collection and analysis, alarm and protection control, and upper- and lower-level communication. A general control system (GBMS) is responsible for data analysis, communication with lower-level systems, and communication with the UPS.
