Abstract

Fast charging is an enabling technique for the large-scale penetration of electric vehicles. However, the pursuit of utmost charging speed risks the violation of critical physical limits companied by the unexpected thermal/stress buildup and side reactions. Motivated by this, this paper proposes a multi-physics constrained fast charging strategy of the lithium-ion battery (LIB). In particular, a novel stress-coupled electrochemical model is established to describe the mechanical-electro-thermal dynamics of the lithium-ion battery (LIB). Based on this, A stress-and thermal-limited fast charging method is proposed based on the model predictive control (MPC) method. Comparative results show that the proposed charging strategy can improve the charging speed of LIB while fulfill the thermal and mechanical tolerance, which promise a favorable thermal safety and longevity.
