摘　　要：为提高电池的性能,研究制定先进的充电策略至关重要。基于差分进化算法,文章提出了一种综合考虑电池寿命和充电效率的多级恒流充电策略。首先,结合锂离子电池外特性与内部机理,建立了电学模型、热学模型和寿命等耦合模型;其次,根据上述耦合模型参数,进一步构造以使用寿命和充电速度为目标的优化方程;最后,采用差分进化算法确定各恒流段的最优充电电流。制定满足消费者需求的安全快速充电策略,不仅有利于电动汽车的推广与普及,而且能够为国家长久可持续发展做出贡献。To improve battery performance,it is critical to investigate specifying advanced charging strategies.Based on the differential evolution algorithm,a multi-stage constant current charging strategy considering battery life and charging efficiency is proposed.Firstly,combining the external characteristics and internal mechanism of lithium-ion batteries,the coupling model of electrical,thermal and life is established.Secondly,according to the above coupled model parameters,the optimization equation aiming at the service life and charging speed is further constructed.Finally,the differential evolution algorithm is used to determine the optimal charging current in each constant current segment.Developing a safe and fast charging strategy that meets consumer needs is not only conducive to the promotion and popularization of electric vehicles,but also contributes to the long-term sustainable development of the country.
