5. 내 용 : The project described in the presentation was aimed at evaluating


road performance of an electric van powered by zinc-air batteries


under typical Israeli traffic conditions. The tests included driving the


vehicle at constant speeds and in an urban driving cycle at various


hours during the day, and with different driving styles.


The experiments also included evaluation of the EV dynamic


performance at various stages of battery depth of discharge. General


observations of the EV performance characteristics, such as behavior


in heavy traffic, hill climbing, etc., have also been made. It was


observed that while driving at constant speed in the range of 50 – 90


km/h, the EV’s energy consumption varies from 0.28 to 0.42 kWh/km


respectively. This means that the diesel fuel consumption equivalent


of this large van (maximal allowed weight of 4.5 ton) is 3 – 4.5


l/100km, better than typical fuel economy of small conventional


passenger cars. The results of the experiments at urban driving


demonstrate the importance of driving style to achieve minimal energy


consumption and as a result –maximal vehicle range.
