Tümüyle Elektrikli Binek Tipli Bir Araçta Yuvarlanma Direnci Değişiminin İvmelenme Performansı ve Transmisyon Kayıplarına Etkisi Üzerine Bir Çalışma

Öz

Elektrikli araçların günümüzde halen istenilen düzeyde kullanılmamasının en önemli sebebi sınırlı menzilleridir. Elektrikli araçların menziline etki eden en önemli faktörlerden birisi yuvarlanma direnci etkisidir. Lastik tasarımına ve çevresel koşullara bağlı olarak değişebilen yuvarlanma direnç kuvveti değişimi fren ve batarya performansıyla birlikte menzili de etkilemektedir. Bu çalışmada binek tipli tümüyle elektrikli bir araç için ADVISOR taşıt simülasyon programı kullanılarak iki farklı yuvarlanma direncinde elektrikli taşıtın ivmelenme ve transmisyon kayıpları incelenmiştir. Sürüş çevrimine göre ortalama yuvarlanma direnç kuvvetleri arasında 2.1 kat fark meydana gelmiştir. Düşük yuvarlanma dirençli lastiklerin hızlanma süresi 0-96.6 km/h hızlar arasında 0.4 saniye, 64.4-96.6 km/h hızlar arasında 0.2 saniye, 0-137 km/h hızlar arasında ise 0.5 saniye azalmıştır. Ayrıca frenleme enerjisi düşük yuvarlanma dirençli lastiklerde % 7.3 daha fazla meydana gelmiştir.

A Study on the Effect of Rolling Resistance Change on Acceleration Performance and Transmission Losses in An All-Electric Passenger Type Vehicle

Öz

The most important reason of electric vehicles are still not being used at the desired level today is their limited range. One of the most important factors affecting the range of electric vehicles is the rolling resistance effect. The change in rolling resistance force, which can vary depending on tire design and environmental conditions, affects the range along with brake and battery performance. In this study, rolling resistance force change, SOC status and battery recovery has been examined in 2 different rolling resistance using the ADVISOR vehicle simulation program for an all-electric vehicle of passenger type There has done a 2.1 times difference between the average rolling resistance forces according to the driving cycle. With low rolling resistance tire acceleration time on has reduced by 0.4 seconds between speeds of 0-96.6 km/h, 0.2 seconds between speeds of 64.4-96.6 km/h, and 0.5 seconds between speeds of 0-137 km/h. In addition, braking energy has been 7.3% higher at low rolling resistance tire.
