Why are battery management systems (BMS) needed and how do they
work?
Battery management systems (BMS) are electronic control circuits
that monitor and regulate the charging and discharge of batteries.
The battery characteristics to be monitored include the detection
of battery type, voltages, temperature, capacity, state of charge,
power consumption, remaining operating time, charging cycles, and
some more characteristics.
Tasks of smart battery management systems (BMS)
The task of battery management systems is to ensure the optimal use
of the residual energy present in a battery. In order to avoid
loading the batteries, BMS systems protect the batteries from deep
discharge, from over-voltage, which are results of extreme fast
charge and extreme high discharge current. In the case of
multi-cell batteries, the battery management system also provides
for cell balancing function, to manage that different battery cells
have the same charging and discharging requirements.
