Real-World Driving Cycles Adaptability of Electric Vehicles

Abstract

Electric vehicles (EVs) include battery electric vehicles (BEVs), fuel-cell vehicles (FCVs) and fuel-cell hybrid electric vehicles (FCHEVs). The performance of vehicles is usually evaluated using standardized driving cycle tests; however, the results from standardized driving cycle tests deviate from the real-world driving cycle. In order to test the adaptability of EVs to real-world driving cycles, conditions of three typical routes in Tianjin are collected and their characteristics analyzed; then BEV and FCV models are created based on a type of FCHEV to simulate 0–100 km/h acceleration and cruising performance under a real-world driving cycle; finally, a motor bench is used to test the performance of FCHEV under the NEDC (New European Driving Cycle). After the adaptability of the three models to real-world driving cycle is compared based on the simulation and test results, it is found that FCHEV can recycle braking energy and has quick dynamic response, which can be well adapted to the real-world driving cycle.

The possibility of energy consumption reduction using the ECO driving mode based on the RDC test

“…Due to the limited range of BEV vehicles, hence the need to plan the trip, forecasting energy consumption and identification of the factors influencing this consumption is extremely important from the user's point of view. Zhichen et al [38] used a simulation to compare the efficiency of energy recovery from a BEV vehicle. Three test routes of different average speeds were selected for comparison.…”

“…An effective method of reduction of the CO 2 emission from a fleet of vehicles is the application of zero-emission, particularly fuel-electric (EV) powertrains. The main group are the widely implemented battery electric vehicles (BEV) and, introduced by some of the carmakers, fuel-cell electric vehicles FCEV [38]. The experts forecast a reduction in the demand for diesel, gasoline and liquefied petroleum gas (LPG) fuels and an increased demand for electrical energy for the charging of BEV vehicles.…”

Yerli Elektrikli Aracın Elektrik Sarfiyatını Güneş ve Rüzgâr Enerjisi ile Karşılama Potansiyeli

“…Hibrit ve elektrikli araçlar emisyonlarla mücadele çok önemli ivme kazandırmıştır (Z. Sun et al, 2020). Yakıt hücreli elektrikli araçlar (FCEV) ve bataryalı elektrikli araçlar (BEV) içten yanmalı motorlara ideal alternatif çözümlerdir (Gürbüz, 2020).…”

“…Yakıt hücreli elektrikli araçlar (FCEV'ler), geleneksel içten yanmalı araçlara kıyasla emisyonları %99.2 oranında azaltabilir (Z. Sun et al, 2020). Dünya genelinde emisyon standartlarının sıkılaşması ve bataryalardaki yeni olumlu gelişmeler nedeniyle elektrikli araçlara (EA) yönelik trend son dönemde önemli bir ivme ile artmaya başladı.…”

Renewable/Fuel Cell Hybrid Power System Operation Using Two Search Controllers of the Optimal Power Needed on the DC Bus

“…For example, automotive applications have a random load profile due to accelerations/decelerations, where the speed of change of current and power is extremely high and sudden [60]. For example, the current consumed by the engine of a vehicle, in the acceleration phase, can reach up to 100 A/s [61]. In these specific applications, mainly, the current is limited by the reaction rate of the PEMFC; therefore, the transient response of the PEMFC is limited to such power demands [62].…”
