Project Description
Problem Statement
Predictable energy crisis and growing environmental concerns have led a trend to pursue new energy substitutes in various environmental-consuming fields. The main purpose of the project is to develop a platform simulating electric vehicles charging process with vivid scenarios, and a user-friendly interface.

Concept Generation
Our system should hava four basic functions and several sub-fuctions with potential solutions. The whole functional synthesis picture is shown below.
Then we explore the inner relationship between the functions. Combining with inputs data set, we get the following graph.
After concept selection process, an overview of the concept diagram is shown below.

Validation
Validation Process:
Since our project focus on the software engineering part, the validation should in turn evaluate the products we design.
For the backend, we check how many variables included in the algorithm and the quality of the simulation platform.
For the frontend, we check whether the dynamic charts are frequently and synchronizedly changing.
Validation Results:
According to validation part, most specifications can be met.
√ coverage area>=1,200,000 m^2
√ # of charing stations <= 40 √ # of vehicles <= 1000 √ ration of solar vs. electric charging stations =1:1
· elements of enviroment >=3
· redundanct influential factors >=3
√ waiting time of launching <=1min √ frequency for data visualizing = 2HZ √ means having been verified and · means to be determined.

Conclusion
The use of solar charging stations can benefit the overall EV charging process. It can not only release the burden on the grid on average, the queuing time of each EV can also be shortened if we add more charging stations. The 3D simulation and data visualization offer a great way to vividly show the traffic and charging condition in a certain area, which may be helpful in the future populization of solar EV charging.
