Battery Maintenance and Test

Battery Internal Resistance Tester High Precision Measuring Instrument

This instrument adopts the high-performance single-crystal microcomputer chip imported from ST Microelectronics, combined with the American “Microchip” high-resolution A/D conversion chip as the measurement control core, and the precise 1.000KHZ AC positive current synthesized by the phase-locked loop is used as measurement signal source apply on the tested element. The generated weak voltage drop signal is processed by high-precision operational amplifier, and the corresponding internal resistance value is analyzed by intelligent digital filter. Finally, it is displayed on large screen dot matrix LCD.

The instrument has the advantages of high precision, automatic file selection, automatic polarity discrimination, fast measurement and wide measurement range.

Overview

1. This instrument adopts the high-performance single-crystal microcomputer chip imported from ST Microelectronics, combined with the American "Microchip" high-resolution A/D conversion chip as the measurement control core, and the precise 1.000KHZ AC positive current synthesized by the phase-locked loop is used as measurement signal source apply on the tested element. The generated weak voltage drop signal is processed by high- precision operational amplifier, and the corresponding internal resistance value is analyzed by intelligent digital filter. Finally, it is displayed on large screen dot matrix LCD.

2. The instrument has the advantages of high precision, automatic file selection, automatic polarity discrimination, fast measurement and wide measurement range.

3. The instrument can measure the voltage and internal resistance of the battery (pack) at the same time. Because of the Kelvin type four-wire test probe, it can better avoid the superimposed interference of the measurement contact resistance and wire resistance, realize the excellent anti-external interference performance, so as to obtain more accurate measurement results.

4. The instrument has the function of serial communication with PC, and can realize the numerical analysis of multiple measurements with the help of PC.

5. The instrument is suitable for accurate measurement of AC internal resistance of various battery packs (0 ~ 100V), especially for low internal resistance of high-capacity power batteries.

6. The instrument is suitable for battery pack research and development, production engineering, and battery screening in quality engineering.

Scope of Use

1. It can measure internal resistance and voltage of ternary lithium, lithium iron phosphate, lead acid, lithium ion, lithium polymer, alkaline, dry battery, nickel-metal hydride, nickel-cadmium, and button batteries, etc. Quickly screen and match all kinds of batteries and detect battery performance.

2. R&D and quality testing for manufacturers of lithium batteries, nickel batteries, polymer soft-pack lithium batteries and battery packs. Purchased batteries quality and maintenance testing for stores.
