US Patent 10086891 Modular electric vehicle

A modular electric vehicle includes a first body module having a lateral connecting side, a second body module having a lateral connecting side, two first wheels mounted to the first body module, two second wheels mounted to the second body module, and a connection unit. The connection unit includes a first electrical connector disposed at the lateral connecting side of the first body module, and a second electrical connector disposed at the lateral connecting side of the second body module. The first electrical connector is operable to be selectively and electrically coupled to the second electrical connector, so that the first and second body modules can be selectively assembled to form a relatively light electric vehicle.
