Influence of Electric Vehicle Charging on Lithium-ion Batteries Aging

International audienceThis paper shows that the way of charging electric vehicle influences the battery aging. A simplified lithium-ion battery calendar aging model is used. This simple battery lifetime model, estimates the capacity fade including the effects due to the temperature and the state of charge. The reference vehicle is a 2018 Nissan Leaf. The entire vehicle, including the battery, the traction system and the road, is simulated with a reference velocity cycle. The energetic macroscopic representation of the vehicle is used for model and control organization. Two charging scenarios are defined. The first scenario corresponds to a daily vehicle charge, while the second one corresponds to one charge every 5 days. The model including the aging of the battery shows a significant difference between the two scenarios in term of capacity degradation through years
