The PMB is equipped with a logical, galvanically isolated limit monitoring, a tried and tested technology for high-precision current measurement.
The PMB (Power Measurement Board) is an intelligent sensor for the accurate measurement of voltage and current in DC currents. The shunt (resistance)-based system is connected via CAN to the BMS with a redundant safety circuit, whereby the state of charge (SOC) of the lithium-ion battery is accurately determined.
