How to Sense Current in a Battery Management System
Resistive Shunt Current Sensor A resistive shunt sensor is a low-value (0.1 mΩ) high-precision resistor in series with a battery pack. This can be seen in the circuit diagram below. We want the resistor outside the battery pack to be of a precise low value, or else it will dissipate a lot of the output energy.
