Title: DEVICE FOR DETECTING CHARGING CURRENT ACCURACY OF CHARGER AND DISCHARGER
Abstract:
The present invention provides a device for detecting the charging current accuracy of a battery cell charger and discharger, comprising a mechanism unit and a power supply unit, wherein the mechanism unit comprises: a box-shaped housing with the top thereof open; a pair of connection terminals which are each mounted on the inside of both sides of the housing and are electrically connected to the power supply unit in order to detect the current accuracy of a charger and discharger; and a plurality of voltage measurement units which comprise a shunt resistor section for applying a constant resistance to the respective connection terminals, and wherein the power supply unit comprises: a charger and discharger for applying a current to voltage measurement units and charging and discharging a battery cell; and a multi-meter for measuring the current and the voltage of the shunt resistor section.
