摘要
不同类型电动汽车对动力电池有不同的性能要求,这必然会造成动力电池的成本有所不同。本文采用电化学仿真模型计算了具有不同功率能量比性能的锂离子动力电池的材料成本,并利用数值拟合找出功率能量比与材料成本之间的函数关系,为电动车设计时动力电池的成本优化提供了参考依据。
Different types of electric vehicles have different requirements for power batteries,which makes the difference of the costs for power battery.In this paper the material cost of lithium ion power battery with different power to energy ratio is calculated by ele ctrochemistry simulation,and the function relationship between material cost and power to energy ratio is found by numerical fitting,which gives a reference for the cost optimization during electrical vehicle design.
