An electric vehicle (EV) chassis is disclosed that may be a modular platform flexible as a basis for numerous other EV platforms. It is contemplated that the entire electric drivetrain (i.e., powertrain, wheels, steering) may be supplied to an automotive original equipment manufacturer (OEM). The OEM may use the EV chassis for integration within a representative passenger compartment. The chassis may also be reconfigurable with the modularity at various levels that include the energy storage system, the entire chassis system, or any level in-between. The chassis may further be designed to allow connection of multiple modules to enable a larger scale energy storage that may be provided to homes, buildings, or the electric power grid.
