BMS Main 2.1
Controller
Modular BMS for 24-1200V batteries
Main 2.1 interacts with measuring modules, calculates the battery state, and protects the battery from damage.
BMS based on the Main 2.1 can control up to 23 measuring modules and manage a battery consisting of 414 cells.
- 4 solid-state relays for contactors
- 4 discrete inputs
- 4 discrete outputs
- SOC, DOD, SOH estimation
- Cycles, energy counting
- CAN, RS-485, Ethernet
- Wi-Fi (over an extension module)
- SD-card logging
- IoT ready
