How to perform DC Internal Resistance measurement with Arbin?

September 22, 2025

Mechanism explanations: Arbin’s MITS software uses pulse method to calculate IR. In order to achieve better accuracy, the software measure the IR 10 times and take the average. The pulse looks like the graph bellows: IIR is the amplitude value T2 is the Extra Control value1 I0 is the offset value IR Calculation Formula: IR […]

Enhancing Battery Testing Safety with a Door Switch Interlock System

September 14, 2025

I. Purpose and Applicability Battery testing—whether for electric vehicles, consumer electronics, or industrial systems—demands strict safety protocols. One often overlooked but critical element in test chamber safety is the door switch interlock system. This simple yet powerful mechanism helps prevent injuries, equipment damage, and test data corruption. In this article, we’ll explore how door switch […]

Integrated Electrochemical Impedance Spectroscopy (EIS) With Arbin Charge/Discharge Channels

August 6, 2025

Introduction Electrochemical Impedance Spectroscopy (EIS) is a foundational diagnostic technique for evaluating battery health, internal resistance, degradation mechanisms, and electrochemical behavior over time. However, EIS is traditionally limited by hardware complexity and high per-channel cost, making it difficult to scale across large battery test systems. To address these challenges, Arbin Instruments offers an integrated EIS […]

Auxiliary Voltage Measurement

July 17, 2025

Introduction The Arbin Auxiliary Voltage Input Module enables precise, high-resolution voltage monitoring for battery testing applications that require measurements beyond the standard I/V channels. Typical use cases include monitoring individual cell or module voltages within a larger pack, measuring reference electrodes in three-electrode cells, or comparing BMS data with directly measured values. Each module supports […]

Constant-C-rate w.r.t. actual capacity, rather than constant current with Arbin cyclers

June 30, 2025

As we all know, the batteries’ capacity degrade by cycle of charge and discharge. If we set the charge and discharge current of a fixed value, such as 1A, 2A,… the length of each cycle will gradually decreases, simply because the battery’s capacity decreases: Cycle time = (Charge Capacity + Discharge Capacity)/Current Sometimes users want […]
