Abstract
Emission standards have grown increasingly stricter, consequently triggering greater interest in issues surrounding environmental pollution. The customer needs for green car without toxic exhaust gas has also become natural and it is represented by pure EV (Electric Vehicle). However, the driving range of EV suffers from A/C (Air Conditioning) for occupant comfort especially in very hot or cold weather. Therefore, the sizing of A/C system is more important than the case of conventional internal combustion engine vehicle. Specifically, EV consumes electric power of battery pack in order to control the comfortability of passenger compartment due to not only the absence of engine heat rejection for interior heating, but no working power of compressor from engine for interior cooling. Therefore, energy consumption for cabin cooling/heating must be optimized for the energy efficiency of EV. In this paper, we concentrate on the refrigerating system sizing because indoor air temperature in hot weather is more sensitive to passenger’s thermal comfort.
Highlights
In recent, car industry has been faced with the higher request from market for a vehicle that is showing better fuel economy and eco-friendly features since the needs of this vehicle has been strongly motivated by high oil prices and stringent emission standards
The maximum vehicle speed for EV is lower than conventional engine vehicle, and available driving range per a single charging is one of key parameters that are affecting the marketability of EV
A/C system is very important for EV development and it is imperative to design an HVAC system optimized for less electric power consumption [3]
Summary
Car industry has been faced with the higher request from market for a vehicle that is showing better fuel economy and eco-friendly features since the needs of this vehicle has been strongly motivated by high oil prices and stringent emission standards. The maximum vehicle speed for EV is lower than conventional engine vehicle, and available driving range per a single charging is one of key parameters that are affecting the marketability of EV. The improvement of these weaknesses can significantly activate current EV market. A/C system to cool down or warm up the cabin for thermal comfort influences directly the decrease of driving range, and it’s important to make a proper sizing of refrigerating and heating systems in EV [2]. We perform several studies to lay out a proper refrigerating system to secure maximum driving range per a single charge
