Charging support in battery electric vehicle (BEV) development

A recent study shows that the on-road transportation contributes to the major part of oil consumption. By replacing the on-road Car with Electric Car, huge amount of oil consumption can then be cut off. However, fossil fuel consumption by power generation will increase while the number of electric cars is increasing unless the portion of fossil fuel consumption uses renewable energy. Although the electric car technology is ready for practical usage, charging problems appeared to slow down the transformation from traditional car to electric car. This paper is going to investigate charger to electric car ratio and strategy. The charging problem on BEV development by different countries such as the US, the UK and China will be illustrated as examples. From the present data of charger and amount of EV, it is possible to predict the demand of chargers for BEV development in the future. Moreover, charger building strategy can be defined base on the users habit.
