BALANCING RESISTOR TESTING APPARATUS

摘要

A balancing resistor testing apparatus is configured for acquiring a resistance of a balancing resistor electronically connected to a supercapacitor of a series supercapacitor assembly in parallel. The balancing resistor testing apparatus includes a controller and a digital potentiometer. The controller detects a voltage across each supercapacitor of the series supercapacitor. The digital potentiometer comprising a plurality of variable resistors each of which is electronically connected to a supercapacitor in parallel, the controller controls the digital potentiometer to continuously adjust the effective resistance of each potentiometer until the controller detects that each supercapacitor has the same or very similar voltage.
