Health-Conscious Charging of Lithium-Ion Battery Cells: Using Physics-Based Models to Minimize Calendar and Cyclic Ageing Effects

Lithium-ion batteries are currently a viable alternative as energy source in vehicles, instead of fossil fuels. However, the usage of such batteries faces multiple challenges such as long charging time and faster degradation. To mitigate these challenges, this paper presents a charging strategy based on Physics-Based Models (PBMs). PBMs can capture calendar and cyclic degradation effects, by modelling lithium plating and SEI growth. Simulation results show that this approach reduces degradation compared to common charging strategies. Additionally, simulations also show that charging in the latter part of the charging window produces the least degradation, because of calendar ageing effects.
