Offline parameter identification can utilize a predefined test profile to fully excite the battery, and high-precision lab facilities can be chosen to measure the battery's current and voltage. Thus, the parameters obtained offline could be used as a benchmark for parameterizing the battery ECM.
Three typical benchmark methods are introduced and validated on a commercial Li-ion battery. The effect of SOC, C-rate and current direction on parameters variation are discussed. The performance of the three methods is validated on HPPC and three different cycles.
However, previous research acknowledges that different vibration tests proposed in standards and regulations for lithium-ion battery packs vary substantially in the levels of energy and frequency range (Kjell and Lang, 2014) so there is still a big challenge to emulate a test that represents the real working condition of electric vehicles.
It enables you to test the charge, discharge, and life cycle testing of EV battery packs and modules. With the help of this system, you can develop your next-generation EV battery packs and modules. The Unico battery test system can be configured as both a battery emulator (or simulator) and a battery tester (or cycler).
3.2.2.1. Batch processing method The least-squares method is naturally suitable for the batch processing of the measurement in a specific window, and thus it is also used for parameter identification of the Li-ion battery ECM offline [151, 152].
