Isothermal Temperature Control for Battery Testing and Battery Model Parameterization

Abstract: The hybrid/ electric vehicle (H/EV) market is very dependent on battery models. Battery models inform cell and battery pack design, critical in online battery management systems and can be used as predictive tools to maximise the lifetime of a battery pack. Battery models require parameterization, through experimentation. Temperature affects every aspect of a battery's operation and must therefore be closely controlled throughout all battery experiments. Today, the private-sector prefers climate chambers for e… Show more

“…11,23 Enhanced thermal control provides an opportunity to achieve thermalisation more rapidly at the new temperature set point, thus reducing the time between OCV measurements. 11,24 However, the consequences of rapid temperature change on PTP have not been reported to date.…”

“…Enhanced potentiometric methods.-Future potentiometric methods should build upon the work of Osswald et al 23 and others, 11,24 as well as considering the effect of both PKP and PTP. The specification for optimised procedural design is set out below.…”

“…Experimental techniques typically used for the parametrisation of ECMs are electrochemical impedance spectroscopy (EIS) [6][7][8], Galvanostatic intermittent titration technique (GITT) [9][10][11][12][13] and hybrid pulse power characterisation (HPPC) [5,[14][15][16][17]. GITT is the most common technique used by the battery industry, in part because it does not require complex cell-cycling equipment.…”

“…The time to complete a GITT procedure can vary, depending on the accuracy of the experimental data required. One set of GITT experiments lasting up to 80 h are commonly reported [11,13]. These include long rest times which are essential to allow the cell to return to chemical and thermal equilibrium between current loading pulses [20,21].…”
