Analysis of relationship between acceleration and battery state-of-charging in electric vehicle

Abstract

Electric vehicle (EV) had the potential for helping to create a more sustainable future as it powered by green technology battery. Therefore, the investigation on battery performance has gained a lot of attention since it is one of advanced technology storage element. This paper reviews an analysis of the relationship between the acceleration of electric vehicles and state-of-charging (SOC) of battery in EV. The energy storage capacity reduction in the battery is inversely proportional to the acceleration rate. As the driving cycles and acceleration rate changing will influence the time taken for the battery to reach 0% of SOC. Several random driving cycles are created in order to identify its relationship with SOC. At the end of this paper, a mathematical equation is introduced to represent the relationship between acceleration rates versus SOC of EV.
