سیستم شارژ همزمان برای وسیله نقلیه الکتریکی

Electric vehicle (EV) has received an intensive attention and been deployed globally due to its beneficial characteristics including higher energy efficiency and lower environmental impacts. However, massive charging of EV leads to several problems to electrical grid because of huge amount of electricity demand and its fluctuation. Therefore, charging management for EVs is urgently demanded. In this study, a novel battery-supported quick-charging system is developed and its performance in single and simultaneous multiple EVs charging is evaluated. The objective of battery installment includes maintaining the charging rate and reducing the burden of electrical grid due to EV charging. In addition, charging behavior of EV under different seasons (winter and summer) is clarified initially. As the results of the study, environmental ambient temperature influences strongly the behavior of EV charging. Charging during summer leads to higher charging rate, hence, shorter charging time. Furthermore, the developed charging system is able to facilitate simultaneous quick-charging for EVs in both winter and summer compared to conventional quick charging system.
