动力多元化趋势下的重型混凝土搅拌车TCO分析

TCO Analysis of Heavy Concrete Mixer Under Trend of Power Diversification

本文旨在探讨不同动力系统重型混凝土搅拌车成本回收期内的TCO差异,识别出最具经济性的动力系统,为混凝土搅拌车制造商、运营商等制定企业战略提供参考。本文重点阐述了成本回收期内因使用阶段能耗成本带来的TCO变化,详细对比实际能耗与WHTC能耗的差值,计算修正系数,推算未来能耗降幅,从而得出柴油发动机动力、天然气发动机动力和纯电动力混凝土搅拌车在2023年至2030年TCO方面的表现情况。柴油发动机动力虽然在购置成本上相对较低,但其高燃料消耗使得长期成本上升。天然气发动机动力购置成本适中,且燃料成本较低,同时排放也更为环保,使得长期成本更优。纯电动力则具有零排放和低能耗成本的优势,但购置成本较高,导致其TCO上升。最后,通过对比TCO模型计算结果,本文提出了未来重型混凝土搅拌车动力系统的选择建议,本研究结果对于重型混凝土搅拌车制造商、运营商具有重要的参考价值。

The purpose of this paper is to explore the difference of TCO in the cost recovery period of heavy concrete mixer trucks with different power systems,identify the most economical power system,and provide reference for the concrete mixer truck manufacturers and operators to formulate enterprise strategies.This paper focuses on the TCO changes caused by the energy consumption cost in the use stage during the cost recovery period,compares the difference between actual energy consumption and WHTC energy consumption in detail,calculates the correction coefficient,and predicts the future energy consumption reduction,so as to obtain the performance of diesel engine power,natural gas engine power and pure electric concrete mixer in the TCO from 2023 to 2030.Although diesel engine power is relatively low in acquisition costs,its high fuel consumption increases long-term costs.Natural gas engines have moderate power acquisition costs,lower fuel costs,and more environmentally friendly emissions,making long-term costs better.Pure electric power has the advantages of zero emissions and low energy costs,but the acquisition cost is high,resulting in the increase of its TCO.Finally,by comparing the calculation results of TCO model,this paper puts forward some suggestions on the choice of power system of heavy-duty concrete mixer in the future.The results of this study have important reference value for manufacturers and operators of heavy-duty concrete mixer trucks.
