摘要

串联混合动力车辆可以将气体发动机、甲醇发动机等低碳发动机与电驱动结合，有效减少碳排放，是当前道路卡车的重要发展方向。串联混合动力系统主要由发电系统、电池和驱动系统组成，通过发电系统与电池共同供电满足车辆运行中的电耗需求。寻求电池和发电系统的最佳功率分配是混合动力节能的关键。针对一种串联气电混合卡车，充分利用电池和发电系统的效率差异，结合道路的负载特性，提出一种全新的混合动力控制方法，可有效提升供电系统的效率，相对于基于规则的控制方法，经济性提升可达10.6%。

Abstract

Series hybrid electric vehicles can combine low-carbon engines such as gas engine and methanol engine with electric drive to effectively reduce carbon emissions, which is an important development direction for road trucks. Series hybrid mainly consists of generation system, battery and drive system, which jointly power supply with the battery to meet the power consumption requirements during vehicle operation. Seeking the optimal power distribution between battery and generation system is crucial for hybrid energy conservation. For a gas-electric hybrid truck, a new hybrid power control method was proposed by fully utilizing the efficiency difference between battery and generation system and combining the load characteristics of road, which could effectively improve the efficiency of power supply system. Compared with rule-based control method, the economy improved by 10.6%.
