Abstract:

Electric vehicles have drawbacks such as long charging time and limited driving range. Based on the charging method of battery swapping, the battery swapping stations and batteries configuration of electric vehicles were investigated in this paper. The processes of battery swapping and charging at swapping stations along a long corridor were described with Birth and Death processes theory, and then a stochastic model for the operation of the swapping station was established.Furthermore, taking the electric vehicle’s probability of swapping a fullycharged battery successfully as the constrain, recharging infrastructure planning models were established with the goal of minimum construction cost, and a model solving algorithm was proposed based on the Lagrange method. Research results show that the proposed model can not only calculate the successful probability of battery swapping, but also analyze the effect of the probability of swapping successfully and the progress of the charging technology, realizing the optimal swapping stations and batteries configuration with minimum construction cost under the constraint of the successful probability of battery swapping.

Key words: transportation planning, electric vehicle, refueling infrastructure, battery swapping
