Technical FAQs 4

What is a battery monitoring system (BMS)?

rent sensors [4–16].9.2.1 Battery Monitoring Systems (BMS)Battery operated systems require a control of the charge and dischar e scheme of the battery and the interaction with the charger. This is done by monitoring the state of charge in the b ttery through voltage, temperature, and current measurements. A current sensor m

How does a BMS measure a battery pack?

Generally, a BMS measures bidirectional battery pack current both in charging mode and discharging mode. A method called Coulomb counting uses these measured currents to calculate the SoC and SoH of the battery pack. The magnitude of currents during charging and discharging modes could be drastically different by one or two orders of magnitude.

How does a BMS measure bidirectional battery pack current?

Therefore, in discharging mode, current flows in the opposite direction from charging mode, out of the HV+ terminal. Generally, a BMS measures bidirectional battery pack current both in charging mode and discharging mode. A method called Coulomb counting uses these measured currents to calculate the SoC and SoH of the battery pack.

What is a current measurement?

h the flow of charge, which runs through electrical circuits. These usually involve a supply, i.e., a battery and a load such as an electronic devi e or an electromechanical actuator such as an electric motor. In most cases, current measurement has
