BMS is the abbreviation of Battery Management System. It is a device to monitor the status of energy storage batteries, which is mainly used for intelligent management and maintenance of each battery unit to prevent over charge and over discharge, prolong the service life of the battery and monitor battery status.
BMS can monitor and collect the status parameters of energy storage battery in real time (including but not limited to single battery voltage, battery pole temperature, battery circuit current, terminal voltage of battery pack, insulation resistance of battery system, etc.), analyze and calculate the relevant status parameters, get more system status evaluation parameters, realize the effective control of energy storage battery body according to specific protection and control strategy, and ensure safe and reliable operation of whole battery energy storage unit.
Meanwhile BMS can communicate with external devices (PCS, EMS, fire protection system) through its communication port, analog/digital input/output ports, ensure the safe, reliable and high-effective grid connection and run of the power station.
BMS developed by SmartGen includes HBCU100 and HBMU100 two modules.
HBCU100 module completes the protection of battery cell and calculation of SOC, SOH through the analysis of battery cell voltage, temperature uploaded by BMU.
HBMU100 module is used for collecting cell voltage and temperature, and uploading external data. HNMU100-16 can collect 16 cell voltage and 8 temperature data, HBMU100-32 can collect 32 cell voltage and 16 temperature data.
The system realizes the protection of cell over/under voltage, over/under temperature, charging/discharging current through battery module data collecting and uploading to monitoring platform, three-level fault protection system and control of external main circuit relay.
BMS can realize protocol compatibility with energy storage converter (PCS) from multiple manufacturers to manage charging and discharging of battery pack. It can be widely used in energy storage battery cabinets of various power levels.
