BMS battery system, commonly known as battery nanny or battery butler, is mainly used to intelligently manage and maintain each battery unit, prevent the battery from overcharging and over-discharging, extend the service life of the battery, and monitor the status of the battery.

BMS is one of the core subsystems of the battery 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 energy 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, and 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 equipment (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.

As one of the common communication methods of BMS, CAN inevitably needs to protect the circuit. SOCAY has rich experience in this area and usually uses TPSMBJ6.0CA vehicle-specific TVS for protection.

Main parameters of TPSMBJ6.0CA: working voltage 6V, breakdown voltage range, 6.67V-7.27V. IPP: 58.25A, power 600W: -55℃ to 150℃, package: SMB. This model has a wide range of applications.

The following is the application circuit of this TVS.

Widely used in automatic transmission, ABS, rear air module, CAN instrument, OBD, window control, electronic anti-theft system, air bag control.
