摘要
分析了电动汽车在给定循环工况下负荷功率的分布情况,进而对驱动电机的额定功率进行了匹配。考虑到实际道路具有一定的坡度,因而对驱动电机的额定功率进行修正,以满足汽车在实际行驶过程中的功率需求。根据对特征工况的分析,得到电动汽车驱动电机的峰值功率以及恒功率扩大系数匹配原则,确定了传动系统挡位数及速比大小。
The distribution of required power when electric vehicle drive on driving cycle was ana lyzed, and the motor' s rated power was matched. Then, taking the road slope into consideration, the drive motor' s rated power was modified to meet the power requirement. Based on the analysis results of individual driving cycle, the matching rule between motor peak output power and constant-power- expanding coefficient was obtained, and the transmission system and ratio values were determined.
