Battery Management Systems

Eaton provides a wide portfolio of products for Battery Management Systems (BMS), including terminal blocks, fuses, supercapacitors, chokes, inductors, and more. Battery Management Systems monitor individual cells, system voltage, current, and temperature. When monitoring individual cells, the BMS balances voltages and regulates the current flow, and if the upper or lower voltage, current, or temperature limit is exceeded, the BMS temporarily disconnects the load or source. Eaton Battery Management Systems estimate the State of Health (SoH), State of Charge (SoC), State of Energy (SoE), and State of Power (SoP) in batteries.
