Abstract
Six pouch-format cells comprising a carbon anode and nickel-cobalt-manganese (NCM) cathode are characterized. Their 1C discharge capacity and open circuit voltage are determined. Internal Resistance is investigated via Hybrid Pulse Power Characterization tests and Electrochemical Impedance Spectroscopy. They are subsequently subject to two different electrical loading profiles, one representing high-performance (HP) driving applications, the other representing urban and extra-urban driving scenarios. The cells are instrumented with thermocouples to determine their surface temperature during cycling. The experimental results show that HP scenarios result in higher temperatures and temperature gradients, requiring bespoke thermal management strategies and suggesting increased degradation over prolonged use.
