Overview of EV battery types and degradation measurement for Renault Zoe NMC batteries

This paper presents a comprehensive review on electric vehicle (EV) battery technologies and an empirical analysis of degradation in Renault Zoe NMC batteries. The extensive review of 50 commercial EV models identifies the dominance of NMC and LFP batteries and changes in composition, such as the reduction of cobalt in NMC batteries. Specifically, the average capacity for NMC type batteries is 68.9 kWh, 62.4 kWh for LFP, and 104.6 kWh for NCA batteries. Simultaneously, we delve into degradation patterns of Renault Zoe models through non-invasive CANBUS measurements. This approach reveals the influence of usage patterns and calendar aging on NMC battery health. Our findings show significant variability in degradation among 2018 R90 models, indicating the critical role of driving behaviors in battery longevity. The study also notes a potential degradation stabilization in the older 2013 Q210 model. These insights contribute to advancing the understanding of battery health in EVs, supporting the development of more sustainable and efficient electric mobility solutions.
