Abstract

A charger system for battery starting current test, comprising: a battery equivalent circuit comprising a battery internal resistance Rand an electromotive force E connected in series, two ends of the battery equivalent circuit are connected to a first signal and a second signal, respectively; a signal drive circuit, comprising a first DC output signal and a second DC output signal, and a first load circuit and a second load circuit configured between the first DC output signal and the second DC output signal, each load circuit is connected to the battery equivalent circuit and controlled by a first drive signal and a second drive signal; an intermediate resistor R, configured between the signal drive circuit and the battery equivalent circuit. This invention uses the above technical solution to test the internal resistance of the battery, and find out the CCA value of the battery via the internal resistance correspondingly.
