Abstract

Elektrikli araçlar çevreci özellikleri ve enerji etkinliği
açısından alternatif ulaşım yöntemi olarak sunulmaktadır. Tek şarj ile
gidilebilecek mesafenin kısa olması bu araçların yaygınlaşmasının önündeki
önemli engellerden biridir. Elektrikli araçların menzili uzatmak için depolama
ve araç teknolojisi üzerine çalışmalar devam etmektedir. Bu çalışmalardan bir
kısmı mevcut enerji kayıplarının azaltılarak aynı batarya kapasitesi ile daha
uzun mesafe gidilmesini amaçlamaktadır. Araçlara uygulanan enerji geri kazanım
sistemleri ile enerji tasarrufu sağlayan çalışmalar mevcuttur. Frenlemede
kaybolan enerjinin geri kazanımı için kullanılan rejenaratif sistemler buna
örnektir. Bu çalışma kapsamında frenleme esnasından kaybolan kinetik enerjinin
geri kazanımı için bir elektrikli araçta simülasyon yapılmıştır. Simülasyon
sonucunda şehir içi kullanım için KERS ile %25 civarında enerji tasarrufu
sağlanabileceği görülmüştür.

Investigation of kinetic energy recovery systems usage in electric vehicles

Abstract

Electric
cars are seen alternative in transport from the viewpoint of environment and
energy efficiency. Short range is one of the challenges facing prevent wide
spreading of these vehicles. Researches on storage systems and vehicle
technology are carried in order to increase the range of EVs. Some researches
aim more distance to go with the same battery capacity by decreasing energy
losses. Some researchers showed that energy conservation systems applicable to
automobile could recover kinetic energy. One of the energy recovery systems is
regenerative braking. In this study, a simulation was conducted to investigate
recovered energy in an electric vehicle with kinetic energy recovery system. As
a result, a 25% of energy saving for model electric vehicle was gathered by
using kinetic energy recovery system under driving circumstances in a sample
city cycle.
