Home › Resources › Application Notes › HPPC Application Note AN-024 Hybrid Pulse Power Characterization (HPPC) Testing with Arbin MITS Pro Summary The Hybrid Pulse Power Characterization (HPPC) test measures the pulse resistance and pulse power capability of a battery across its state-of-charge (SOC) range. This application note describes the HPPC method, the cycler characteristics […]
Mechanism explanations: Arbin’s MITS software uses pulse method to calculate IR. In order to achieve better accuracy, the software measures the IR 10 times and takes the average. The pulse looks like the graph bellow: IIR is the amplitude value T2 is the extra control value1 I0 is the offset value IR Calculation Formula: IR […]
IR measurement is crucial to have an insight into a battery. There are many way, i.e. many standard to measure battery’s IR. This article will introduce IEC 61960 standard and how to implement it using Arbin’s equipments. IEC 61960 standard for battery IR: In this standard, a discharge pulse of 0.2C is given for 10 […]
