The Seplos SP-HV-36S integrates a Battery Control Unit (BCU), Battery Monitoring Unit (BMU) and intelligent fan control into a coordinated high-voltage battery management solution. The BCU provides protection against overcharge, over-discharge, overcurrent, high temperature and low temperature, together with a multi-level alarm mechanism.
The BMU performs real-time voltage and temperature monitoring at cell level and supports 19–36 cell nodes. Isolated CAN and RS485 communication, passive balancing, fan control and fault detection help support flexible integration into high-voltage energy storage systems.
Battery Protection
Multi-level protection against overcharge, over-discharge, overcurrent and abnormal battery temperatures.
Precision Cell Monitoring
Real-time cell voltage and temperature sampling helps track battery status and detect abnormal conditions.
CAN & RS485 Communication
Isolated CAN and RS485 interfaces support real-time communication between BMU, BCU and compatible system controls.
Balancing & Thermal Control
Up to 200mA passive balancing with temperature-based fan control and PWM speed regulation.
Review the key electrical, environmental and communication parameters before confirming battery configuration and system compatibility.
Use these values for preliminary battery pack, inverter and current matching before final technical confirmation.
