新能源汽车分时租赁模式下电池耐久性设计策略研究

Battery Durability Design Strategy for Electric Vehicles under Per-use Rentals

针对分时租赁模式与新能源汽车设计之间相互影响的现象,本文采用委托代理理论框架,通过初始续航里程与衰减速度刻画电池衰减过程,构建了制造商电池耐久性最优设计模型。研究发现,分时租赁模式下制造商会采取与销售模式不同的耐久性设计策略。当充电不便捷用户较多时,分时租赁模式会激励制造商设计续航里程更长且衰减速度更快的车型。当充电不便捷用户较少时,分时租赁模式会激励制造商设计续航里程更短且衰减速度更慢的车型。

According to the phenomenon regarding to the interaction of per-use rentals and the EV design,this paper employs the principal-agent theory framework to construct an optimal manufacturer's battery durability design model.The battery degradation process is characterized by the initial driving range and degradation rate.The study reveals that under the per-use rental model,the manufacturer adopts durability design strategies different from those under the sales model.When there is a higher proportion of users facing inconvenient charging,the per-use rental model motivates the manufacturer to design vehicle models with longer initial driving range and larger degradation rate.Conversely,when there are fewer users facing charging inconvenience,the per-use rental model encourages the manufacturer to design models with shorter initial driving range and smaller degradation rate.
