Abstract

The invention discloses a portable storage battery performance test device. The device comprises: a control module used for sending a test digital signal; a digital-to-analog conversion module used for performing digital-to-analog conversion on the received test digital signal to obtain a test analog signal; an operational amplifier module used for carrying out operational amplifier processing onthe test analog signal to obtain an operational amplifier signal; an alternating current power supply output module used for outputting a test alternating current signal according to the operational amplifier signal; a signal acquisition module used for acquiring an output signal after the test alternating current signal passes through the tested storage battery; an internal resistance measurementmodule used for performing internal resistance measurement on the output signal to obtain an internal resistance analog signal; and an analog-to-digital conversion module used for performing analog-to-digital conversion on the internal resistance analog signal to obtain an internal resistance digital signal, wherein the control module is also used for receiving the internal resistance digital signal to obtain an internal resistance test result, and the tested storage battery is converted into a power supply by a power supply module. The device has the technical characteristics of being portable and accurate in measurement.

Description
