摘要
电动汽车能耗水平是限制其快速发展的关键因素。开展基于整车能量流分析的车辆能耗因素研究有助于提升电动车能量管理策略,能够更好地进行整车目标分解,同时有助于提升自主品牌技术提升。文章以某款先进纯电动汽车能量流测试为例。通过对车辆构型分析、对标方案设计、总线信号解析及关键部件传感器安装,实现对车辆高压系统、低压附件系统、机械系统等开展能量流分析,对提升能耗水平具有重要意义。
The energy consumption level of electric vehicles is a key factor that restricts their rapid development.The research on vehicle energy consumption factors based on the analysis of vehicle energy flow is conducive to improving the energy management strategy of electric vehicles,better decomposes the vehicle target,and improves the technology of self-owned brands.This paper takes the energy flow test of an advanced pure electric vehicle as an example.Through vehicle configuration analysis,benchmarking scheme design,bus signal analysis and key component sensor installation,the energy flow analysis of the vehicle's high-voltage system,low-voltage accessory system and mechanical system is realized,which is of great significance to the improvement of energy consumption.
