Power Battery/Energy Storage Battery Cabinet Tester

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.

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's 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 Reliability

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

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