Communication and System Integration

The integrated high-voltage BMS provides multiple communication interfaces for battery system integration:

  • CAN: 1 channel for communication with compatible PCS or UPS equipment.
  • RS485: 1 channel for communication with compatible PCS or UPS equipment.
  • TCP/IP: 1 channel for communication with a host computer.

Communication compatibility depends on the inverter or PCS model and its communication protocol. Please provide your equipment brand and model so our technical team can verify compatibility.

Battery Protection and Safety Functions

The integrated BMS is designed to monitor battery operating conditions and provide protection against abnormal situations. Its protection functions include:

  • Charging and discharging control
  • Battery voltage monitoring
  • Cell temperature monitoring
  • Passive cell balancing
  • Short-circuit protection
  • Alarm indication
  • Two-level protection strategy

When an abnormal condition is detected, the BMS triggers the corresponding protection response according to its configured protection logic.

Applications

This 120–350V integrated high-voltage BMS can be used in selected lithium battery applications, including:

  • Residential battery energy storage systems
  • Commercial and industrial energy storage systems
  • Lithium battery packs
