As the electrical vehicle industry grows rapidly, the technology development and distribution status raised our interest. In this work, we studied the electrical vehicle industry organization structure and technology development. From the patents that leading companies have, we successfully clustered their abstract and identified the corresponding applied component on the car through machine learning techniques to process the natural language. I compared the patent by number and type between NIO and Tesla. Ultimately, I made the HTML interactable visualization graph for an electrical vehicle to intuitively demonstrate patent information.
