Battery Cell Grading and Matching: Why Measurement Precision Determines Pack Performance
Home › Resources › Application Notes › Cell Grading & Matching Application Note AN-025 Battery Cell Grading and Matching: Why Measurement Precision Determines Pack Performance Summary A battery pack is only as good as its weakest cell. In a series string, charging stops when the first cell reaches its upper voltage limit and discharging stops […]

How to Set Up a GITT Test Schedule in Arbin MITS Software
I. Introduction The Galvanostatic Intermittent Titration Technique (GITT) is an electrochemical method commonly used to study ion diffusion behavior and transport kinetics in battery electrode materials. A typical GITT test consists of a sequence of constant-current pulses followed by open-circuit relaxation periods. During each current pulse, the cell voltage changes as the state of charge […]
How Can Current Measurement Offset Make Coulombic Efficiency Appear to Exceed 100%?
One common reason that measured coulombic efficiency (CE) can appear to exceed 100% is a current measurement offset. In this example, assume the cycler has a constant negative current offset e. This means the measured current is lower than the true current by e throughout the test. To simplify the analysis, assume an ideal battery […]
Run the cycling test until the capacity decreases to 80% of original capacity
A common end-of-life criterion for lithium-ion cells is when the measured discharge capacity falls to 80% of its initial value. This document demonstrates how to configure an Arbin test schedule to automatically cycle a cell until this threshold is reached. Overall test procedure: Initial capacity measurement → Cycling loop → Compare capacity to 80% → […]
사용자 정의 메타변수 (MV_UD)의 응용 예
Arbin 소프트웨어에서 MV_UD(사용자 정의 메타 변수)는 배터리 테스터를 제어하는 강력한 도구입니다. 이 문서는 Arbin MITS 소프트웨어에서 MV_UD를 사용하는 방법을 설명합니다. SetValue(s)를 사용하여 MV_UD에 값 저장 Control Type 목록에서 SetValue(s)를 선택합니다. SetValue(s)는 특정 순간에 물리량의 고정된 값을 할당합니다.
