摘要：

为应对未来动力电池大规模退役带来的梯次利用需求,针对梯次电池用于储充电站的应用场景,提出了一种基于梯次利用寿命周期内电池健康评估模型的储能充电站能量优化控制方法。基于动态安全裕度的分析,所提方法可降低用电成本,同时有效延长梯次电池的循环寿命。算例分析验证了方法的有效性与经济性。

关键词: 梯次电池, 动态安全裕度, 储充站点, 能量优化

Abstract:

In order to meet the demand of echelon utilization brought by large-scale decommissioning of power battery in the near future,an optimal control method according to the battery health assessment model in the whole life cycle in the application scenario of charging station with energy storage system was proposed.With the optimal control method,the output power of echelon energy storage system was limited while the cycle life was effectively extended.The feasibility and effectiveness of the model was proved by the example analysis.

Key words: second-use batteries, dynamic safety margin, charging station with ESS, energy optimization
