BMS (Battery Management System) is one of the core subsystems of battery energy storage systems. It is a system that uses energy storage as a carrier to manage the storage of electric energy and the supply of electric energy over a certain period. The electric energy managed by BMS has functions such as smooth transition of electric energy, peak shaving and valley filling, frequency regulation and voltage regulation. It is also a device that monitors the status of energy storage batteries, intelligently manages, and maintains each battery unit, prevents over-charging and over-discharging of batteries, prolongs battery life and monitors battery status.
Its principal works are:
  • Battery status monitoring: Single battery voltage, battery pole temperature, battery loop current, battery pack terminal voltage, battery system insulation resistance, etc.
  • Battery state analysis: State of charge, power state, aging state.
  • Battery safety protection: overcurrent protection, overcharge protection, overtemperature protection
  • Energy control management: charge control, discharge control, balance control
  • Battery information management: battery information display, battery history information storage, information interaction within and outside the system
BMS works with PCS(Power Conversion System), EMS（Energy Management System）, special air conditioning and fire protection systems to form the link control for each subsystem in the entire energy storage power station, ensure safe, reliable, and efficient grid-connected operation of mobile energy storage systems.
