What is BMS for Lithium battery of solar energy system?
BMS for solar energy batteries
The full name of BMS is Battery Management System. It is a device used to monitor the status of solar energy storage lithium battery. BMS is mainly used to intelligently manage, and maintain each lithium battery unit, prevent the battery from overcharging and over-discharging, extend the service life of the lithium battery, and monitor the status of the battery. Generally, the BMS appears as a circuit board or a hardware box.
BMS is one of the core subsystems of the lithium battery, for solar energy storage system. It is responsible for monitoring the operating status of each battery, in the battery energy storage unit, and ensuring the safe and reliable operation of the power storage unit.
BMS can monitor and collect the status parameters of energy storage batteries in real time (including but not limited to single cell voltage, battery pole temperature, battery loop current, battery pack terminal voltage, battery system insulation resistance, etc.), and perform necessary operations on related status parameters.
Through analysis and calculation, more system status evaluation parameters can be obtained, effective management and control of the energy storage battery body, can be achieved according to specific protection control strategies, to ensure the safe and reliable operation of the entire battery energy storage unit.
At the same time, the BMS can interact with other external devices (PCS, EMS, fire protection systems, etc.), through its own communication interface, and analog/digital input interface, to form linkage control of various subsystems in the entire energy storage power station, to ensure the safety and reliability of the power station, efficient grid-connected operation.
