The voltage of the battery power system is increased to reduce the power loss caused by the power transmission. To obtain operational safety in a higher-voltage battery power system, multiple cells must be divided into multiple modules so that the BMS can provide monitoring, cell-balancing, and protection functions to all the cells by modular architecture design.
One of the key components of a BMS is the schematic, which provides a detailed representation of the system’s architecture, including the various sensors, modules, and circuits involved. The battery management system schematic serves as a roadmap for engineers and technicians involved in the design and implementation process.
