基于中国工况的纯电动续驶里程测试方法优化

Optimization of Testing Method for Pure Electric Vehicle Driving Range Based on China Light-duty Test Cycle

GB/T 18386.1—2021对纯电动轻型汽车的续驶里程测试采用中国工况,且在流程中引入了缩短法,其里程预估策略严重依赖于预先开展摸底试验提供的参考里程,经济负担较大。本文提出以能量预估法来替代缩短法中的里程预估法,以免去摸底试验,降低试验成本,也为后续相关标准制修订提供参考。

GB/T 18386.1—2021 adapts China Light-duty Test Cycle to test the driving range of pure electric light vehicles and brings the shortening method in the process.Its mileage estimation strategy relies heavily on the reference mileage provided by compliance tests conducted in advance,which has a larger economic burden.This paper proposes the energy estimation method to replace the mileage shortening method to avoid the compliance test and reduce test cost,and also to provide a reference for subsequent relevant standard revisions.
