This paper focuses on energy efficiency degradation of two lithium-ion technologies, NMC (Nickel Manganese Cobalt) and LFP (Lithium Iron Phosphate), under accelerated calendar ageing tests. Results reveal the importance of considering battery ageing in the design phase of electric vehicles, not only for capacity but also for energy efficiency reasons.
