Brunstock’s battery management system has a three-tier architecture (BAMS, BCMU and BMU). This gives the battery system flexibility, insulation, better interference resistance and more than one communication protocol. Chip-level equalisation technology ensures longer battery life, safety and working efficiency.
The 32-bit high performing MCP (Main Control Processor) uses real-time information to provide multi-dimensional diagnostics and offers multi-tier BMS safety technology, which support high-precision data.
Functions
- Data collection and monitoring for total voltage, current, cell voltage and temperature
- Battery system fault detection and protection
- Support battery system insulation detection
