V-BMS SWITCH MODULE
Up To 100V & up to 200A
V-BMS Switch module monitors battery current with built-in shunt resistor and controls connection to the charger & load over 2 separate paths via internal MOSFET’s. It also serves as a master module for the battery management system; sharing & gathering data to/from slave modules and evaluating warnings & alarms.
- Supports up to 50 BMS Modules & up to 16 parallel strings
- Fully programmable CANBus interface & charger control functions
- Fully plug & play; detects connected modules, number of cells, number of sensors, number of strings and string shunts
- Configurable Modbus port for monitoring & controlling the system
- All module configuration can be managed using cross-platform V-BMS software.
