Ports
The BMS has two ports for current flow:
- DSC (Discharge) port — Main port connected to the load (motor controller, inverter, etc.)
- CHG (Charge) port — Port connected to the charger
Each port has its own current-sensing, voltage measurement, protection parameters, and per-port current limiter.
The port switching is managed by the state machine. Use the sw shell command to manually control the ports:
sw 0— Turn OFF both portssw 1— Turn ON (DSC only)
