Overview

The ANBTS7520(F)Series Battery Tester utilizes a 1kHz AC constant current source and four-terminal method to  measure the AC internal resistance(ACIR) and open circuit voltage (OCV) of lithium batteries, providing the resolution of the AC impedance as low as 0.1uΩ, excellent anti-interference ability and anti-spark design.

The ANBTS7520(F) Series Battery Tester is widely applied in such processes as the battery offline detection, etc. of  the power batteries, the energy storage battery cabinets and other high-voltage large modules\battery packs.

Features

High-accuracy test

Battery internal resistance ranges from 0.1uΩ to 3.1kΩ, with 0.5% accuracy, and 7 range levels.

Open circuit voltage ranges from 10uV to 2100V, with 0.01% accuracy, and multiple range levels.

Comparator function

The battery internal resistance and open circuit voltage have comparator function switches, which can be used to set upper and lower limits for resistance and voltage respectively, compensating for testing.

Test reliabilty

AC four-terminal method testing, with 4mm diameter coaxial contact points and interference-resistant testing cables. Contact detection function, with  programmable  anti-spark design.
