BMS Main 2.1
Controller
Modular BMS for 24-1000V 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 20 measuring modules and manage a battery consisting of 360 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

BMS Main 2.1 can be configured using the web interface over Ethernet or a Wi-Fi network (in this case, the BMS Wi-Fi module must be installed).
Another way to configure BMS Main 2.1 is to use ElectricDeviceMonitor software. A USB-CAN adapter is required to connect to the device.
