Circular economy principles are becoming increasingly important to ensure sustainable growth of Electric Vehicle (EV) uptake predicated to be up to 15% of new vehicle sales by 2025 in the EU alone. In order to extend retention of key resources within the supply chain and extract maximum value from them, the battery’s End-of-Life (EoL) performance evaluation requires careful consideration. International standards and best-practice guides exist, which address the performance evaluation of both EV and Hybrid Electric Vehicle battery systems. However, a common theme is that the test duration can be excessively time consuming. The aim of this paper is to present a novel accelerated test strategy by increasing the charge/discharge rates and reducing wait times between charge/discharge events for energy capacity and impedance measurement of Li-ion traction battery modules currently available on the market. Underpinned by previously published cell level accelerated experiments, two commercially available modules from battery and hybrid electric vehicles were assessed in a temperature-controlled environment. This paper, for the first time, critically evaluates whether traction battery module experiments can be accelerated; reducing the test duration time to facilitate regenerating products at the end of their service life. Experimental results at 25 degrees C are presented that highlight it is possible to significantly reduce the duration time of the traction battery module characterisation test by circa 70% with accelerated testing compared to standard tests whilst maintaining measurement accuracy within 1% and 3% for capacity and impedance respectively. The trade-off between test accuracy and test time is described, allowing stakeholders to optimise the evaluation strategy they employ within the context of their respective commercial sectors, which facilitates further EoL options for used EV and HEV battery systems.
