A current sensor is a device that is used in order to calculate (observe) how much electric current is flowing through a given wire. This is very important for calculating state of charge as well as determing battery limits such as CCL and DCL.
Every current sensor has a given range that it can measure (say -100 amps to 100 amps). It is essential that an appropriately sized current sensor is selected for the given application to maximize accuracy.
