Key Features
1. Active Balancing
Up to 2A Active Balancing
Transfers energy between cells to improve voltage consistency rather than relying on low-current passive balancing. Balance parameters can be configured through the BMS software.
2. Inverter Communication
CAN & RS485 Communication
Designed for energy storage applications with CAN and RS485 communication interfaces. Inverter communication protocols can be selected through the APP according to the system configuration.
3. Bluetooth Monitoring
Smart APP Monitoring
Monitor cell voltage, current, temperature, SOC and BMS status from a compatible Android or iOS device via Bluetooth.
4. Parallel System Support
Multi-BMS Monitoring
Up to 16 BMS units can be addressed and monitored through an RS485 bus using the interface-board DIP switches.
5. Heating Control
Low-Temperature Heating Support
Supports control of an external resistance heater or heating film for battery systems operating in cold environments.
