EFT-BMS-1x
The EFT-BMS-1x (Battery Management System) is designed as a modular BMS platform that can be quickly adapted to monitor and control any battery pack.
It includes all relevant monitoring functions (Voltage, Current, Temperature) as well as control functionality (Cell Balancing, SoC-State of Charge, SoH-State of Health, SoP-State of Power).
An individual BMS Slave Unit is configured for up to 12 cells in series, but it can be daisy chained to up to 192 cells in series. This allows to monitor battery packs from 40V up to 800V.
Monitoring
Monitors all relevant battery data (Voltage, Current, Temperature) to allow safe operation.
Management
Processing of battery data to derive accurate SoC, SoH and SoP values.
Modularity
Simplified interfaces and scalability to different voltage levels.
