The working principle of a battery shunt resistor is fundamental to understanding its role in current measurement and overall battery system management. When connected in parallel to the battery, the shunt resistor serves as a crucial component for accurately measuring the current flowing through the system. This discussion will delve into the basic working principle of a battery shunt resistor, explaining its connection to the battery and its essential role in providing a low-resistance path for current measurement.

A measurement method for parallel resistance of solar cells 1. The larger the series resistance is, the more the short circuit current drops, and the more the filling factor will accordingly; The smaller the shunt resistance, the greater the current, the more the open circuit voltage drops, and the more the fill factor drops.

Motor test measurements usually require ammeters to be equipped with multiple shunt units to solve the problem of ensuring the desired measurement accuracy over a larger measurement range. At this point, the rated voltage drop of all shunt used must match that of the ammeter (e.g. 75 mV).
