Leoch offers a safe LiFePO4 battery solution for UPS and energy storage systems with good compatibility and safe long cycle life. The battery system consists of a three-level architecture, with a module-level management system BMU integrated in the battery pack, which is responsible for collecting the information of single cell voltage, module temperature, battery equalization, and communication with upper management system. The adopted CBMS cabinet-level management system is responsible for battery current detection, data collection and analysis, alarm and protection control, and communication with the upper and lower levels. The general control GBMS is responsible for data analysis, lower level system communication, and UPS communication.
