BMS Mini
Centralized BMS for 24-72V batteries
Mini is a full-featured centralized BMS for high-capacity lithium-ion batteries. It has many communication interfaces, an ability to collect information during the entire battery lifetime and an integrated DC/DC converter.
BMS Mini can manage a battery consisting of 6 to 18 cells.
- 4 MOSFETs for contactors
- 4 discrete inputs
- 4 discrete outputs
- SOC, DOD, SOH estimation
- Cycles, energy counting
- 3xCAN, RS-485, Ethernet
- Wi-Fi (over an extension module)
- SD-card logging
- IoT ready
