摘要
锂离子电池的功率状态(SOP)是影响电池安全、保证车辆动力性能的重要参数。锂离子电池SOP的估计受到温度、荷电状态、老化程度(SOH)等多种因素的影响,导致SOP的估计精度下降或方法变得更加复杂。在对当前锂离子电池SOP估计的各种方法综述和分析比较了各方法优缺点的基础上,对未来该技术发展趋势做出了预判。
The State of Power (SOP) of lithium-ion battery is an important parameter that affects battery safety and ensures vehicle dynamic performance. The estimation of the SOP of lithium-ion battery is affected by various factors such as temperature, state of charge and aging, etc., resulting in a decrease in the accuracy of the SOP estimation or a more complicated method. This paper introduced the current methods of SOP estimation for lithium-ion batteries, summarized the SOP estimation methods, and analyzed the advantages and disadvantages of each method to predict the future development trend.
