| 摘要: |
| 退役动力电池的梯次利用是电动汽车行业可持续发展急需解决的问题。为确保梯次电池储能系统的经济性，在规划阶段需对储能系统进行容量配置，提出了基于雨流计数法和等效循环寿命法的梯次电池寿命评估方法。考虑容量保持率变化对储能系统寿命和经济性的影响，以储能系统实际运行寿命内净收益总和最大为目标，提出了梯次电池储能系统容量配置方法，并引入萤火虫算法进行优化求解。算例结果显示，考虑运行寿命内经济性最优的容量配置方法能够提高梯次电池储能系统的经济性，同时延长储能系统寿命。 |

| Abstract: |
| The second use of a retired battery is an urgent problem needing to be solved for sustainable development of electric vehicles. To ensure the economy of a second-use battery energy storage system, considering the capacity configuration during the planning stages, a method is proposed for predicting the second-use battery service life based on equivalent cycling life and the rain flow counting method. Considering the impact of changes in capacity retention rate on energy storage system life and economy, an optimization model is built for the capacity configuration. This aims at the maximum net present value of total service life. The optimization results are obtained by a firefly algorithm. The results of numerical examples show that the capacity configuration method of the second-use battery storage system considering economic optimization within service life can increase the net present value and extend the life of the energy storage system.
