Analysis of ways to reduce energy consumption for heating passenger compartment of electric buses
EDN: OUUYQZ
Abstract
Introduction (problem statement and relevance). For regions with cold climates, the cruising range of electric buses becomes a serious obstacle to expanding the use of this type of transport. Increased energy consumption affects not only the autonomous cruising range, but also the battery life, fleet operation timetable and charging infrastructure loading. In this regard, the search for the ways to reduce the HVAC system energy consumption is a relevant task.
The purpose of the study is to determine the energy consumption for heating the cabin and passenger compartment of the electric bus during the autumn and winter period of operation in the Moscow region as well as search and analysis of the ways to reduce this consumption.
Methodology and research methods. In order to determine the air temperature in the passenger compartment, the mathematical model was used based on the heat balance equations and validated following the field tests results. The research was performed according to the GOST R 53828-2010 requirements.
Scientific novelty and results. The test results are given in terms of determination of the microclimate parameters and energy consumption for passenger compartment heating in case of different driving modes. The heat losses ratio through different leak paths was determined by means of the mathematical model. A comparison of energy consumption for the HVAC operation when using different energy consumption reduction methods is given.
Practical significance. The results of this study can be used to improve the energy performance of electric passenger transport.
