Design and Simulation of battery swapping system for electric vehicles

As the economy develops and the people's living standards improve, the number of cars in the world has maintained rapid growth, which is threatening the ecological environment. Driven by the energy conservation policy, renewable energy generation will get rapid development. Thus, the electric car is the best complement to renewable energy. Growing the electric car can not only satisfy the needs of people's travel but also promote energy conservation and emissions reduction, which can be the strategic direction of the development of the auto industry. In this article, we will discuss a delay charging model: A part of batteries in day high electricity consumption period will not be charged until low electricity consumption period arrives. Thanks to low unit electricity cost at night, this strategy could decrease the operating cost and power grid load pressure. This sizing and operation of this station, call Battery Swap Station (BSS), will be investigated in this work through a configurable simulation model able to generate different scenarios taking as a case study the city of Turin. By changing the number of charging bay and stored batteries, finally, find a proper warehouse design to satisfy the customers’ requirements. The simulation model has been implemented in FlexSim, a 3D simulation modeling, and analysis software. Series of experiments are then designed and simulated in order to show which factors could affect the performance of the station. Afterward, several useful performance measures will be tracked and analyzed. Finally, through a series of simple standards, the most suitable solution is provided to the case study.
