<p>Distributed drive electric vehicle (DDEV) is experiencing rapid progress in development and industrialization, with different configurations to integrate numerous components in the chassis space. The mechanical and electrical connection network of all the components consists of the core element of system configuration, which should be considered systematically and comprehensively. Different from the traditional engineering drawing, this paper creatively introduces the graph theory concept as a systematic analysis methodology for DDEV configurations. By the position of the drive motor, the existing company products and scholarly research configurations can be classified into three types. They are: (i) DDEV with centralized motor and half shaft, (ii) DDEV with close-to-wheel motor and speed-reducer mechanism, and (iii) DDEV with in-wheel motor configuration. Furthermore, DDEV’s future trends are discussed, such as corner modules for chassis-by-wire technology, wireless power transfer technology, magnetic gear machine technology, and dynamic vibration absorber applications. Finally, the various DDEV configurations are evaluated and presented in the radar charts with conclusions. For the research of DDEV technology, this paper offers theoretical support for system analysis, configuration synthesis methodology, and technical direction prospection in industrial applications.</p>
