Abstract
The use of battery electric vehicles (EVs) is spreading around the world due to their advantages. The presence of large batteries makes electric cars heavier, and due to their position, the vehicle’s center of gravity is lowered compared to conventional internal combustion engine cars. The weight of an impacting vehicle is one of the critical parameters for the acceptable performance of longitudinal barriers. It is anticipated that EVs could pose failure risks for conventional safety hardware, yet there is still no revision regarding the use of EVs in existing full-scale crash test standards. In this study, the effect of electric cars on the crash performance of the H1 containment level longitudinal steel safety barrier was investigated through computer simulations. Three different vehicle models, each weighing 900 kg and currently used for TB11 finite element analyses, were modified according to the features of the selected reference EVs. Barrier crash performance was evaluated in terms of occupant safety and structural adequacy. Analysis results showed that with increasing vehicle weights in EV tests, injury severity indices become smaller, while the damage to the barrier gets larger. Further investigation of the crash performance of existing barriers with EVs is highly recommended.

Abstract
Elektrikli araçların kullanımı, avantajları nedeniyle tüm dünyada yaygınlaşmaktadır. Büyük bataryalar elektrikli arabaları ağırlaştırmakta ve konumları nedeniyle aracın ağırlık merkezini, geleneksel içten yanmalı motorlu arabalara göre daha alçak hale getirmektedir. Çarpan aracın ağırlığı, güvenlik bariyerlerinin kabul edilebilir performansı için önemli parametrelerden biridir. Elektrikli araçların geleneksel güvenlik tertibatları için başarısızlık riski oluşturabileceği öngörülmektedir. Ancak mevcut tam ölçekli çarpışma testi standartlarında elektrikli araçların kullanımına dair henüz bir güncelleme bulunmamaktadır. Bu çalışmada, elektrikli arabaların H1 performans seviyesi çelik güvenlik bariyerinin çarpışma performansına etkisi bilgisayar simülasyonlarıyla incelenmiştir. Her biri 900 kg ağırlığında olan ve halihazırda TB11 sonlu elemanlar analizlerinde kullanılan üç farklı araç modeli, seçilen referans elektrikli araçların özelliklerine göre modifiye edilmiştir. Bariyerin çarpışma performansı, yolcu güvenliği ve yapısal yeterlilik açısından değerlendirilmiştir. Analiz sonuçları, elektrikli araç testlerinde araç ağırlığının artmasıyla yaralanma şiddet indekslerinin küçüldüğünü, bariyerdeki hasarın ise büyüdüğünü göstermiştir. Mevcut bariyerlerin elektrikli araçlarla çarpışma performansına ilişkin daha fazla araştırma yapılması önerilmektedir.
