A modular electric vehicle system, allowing for the assembly of many different vehicle configurations using a plurality of interchangeable vehicle assembly modules, including at least two powered vehicle assembly modules in an assembled vehicle each of which has self-contained drive and power systems and controls which can be connected together by a central network bus on the vehicle. At least one of the powered vehicle assembly modules will be a steering module, with the necessary additional controls and components to steer the axle thereon and in turn steer the assembled vehicle. The connection of the network bus and the modules would be done in an interchangeable way so that different modules could be interchangeably placed in the assembled vehicle. Various steering systems, control methodologies and vehicle attachments are also disclosed.

A multipurpose vehicle system with interchangeable operational components and power supplies is operational in multiple operational modes. The operational modes include: a personal transport vehicle mode, a service vehicle mode, and a commercial vehicle mode. The vehicle system has a dimensionally adjustable chassis module. The chassis module has the capacity to detachably attach to multiple exterior, interior, motor, and transmission components. The chassis module supports a cabin module and a rear module that enables formation of different iterations of vehicles. The vehicle system provides multiple different and interchangeable power supplies, like a rechargeable battery and a hydrogen tank. The power supplies are interchangeable. The used components can be recycled and interchanged with new components. The vehicle system also comprises at least one autonomous trailer that comprises a receiver in communication with a transmitter in the chassis module, allowing the autonomous trailer to be remotely towed by the chassis module.

An assembling method of an electric vehicle comprises the steps of: assembling a vehicle body including a frame, wheels and an electric motor; conducting a vehicle body test including confirmation of a state of driving power transmission from the electric motor to the wheels by connecting an electric power supply unit installed in a vehicle body test place to the electric motor of the vehicle body and supplying electric power from the electric power supply unit to the electric motor; detaching the electric power supply unit from the electric motor and transporting the vehicle body which has passed the vehicle body test from the vehicle body test place to a mounting place, in a state in which a battery is not mounted to the vehicle body; and mounting the battery to the transported vehicle body in the mounting place.

The disclosure is directed to methods and systems for provisioning mobile electric vehicles with various operational settings data transmitted over the air. A vehicle or its components may operate according to operational settings corresponding to operational settings data included in the vehicle components. A server that is remote to the vehicle may comprise operational settings data and may transmit operational settings data to the vehicle. The server may transmit operational settings data automatically, such as on a periodic basis, in response to a request, such as from a user or from a vehicle component or anytime new or updated operational settings data are available for the vehicle or its components.

A method for producing an organic electronic component and an organic electronic component are disclosed. In an embodiment the component comprises at least one organic electronic layer having a matrix, wherein the matrix contains a metal complex as a dopant, wherein the metal complex comprises at least one metal atom M and at least one ligand L bonded to the metal atom M.

Provided are systems and methods for a public standard interface including a Battery Management System that allows for communication between an alternative energy source and a material handling vehicle. The alternative energy source may be a Lithium Ion Battery, a fuel cell, or another non-lead acid based battery. The Battery Management System is coupled with a CAN bus that allows for communication between the material handling vehicle and the alternative energy source. The CAN bus communicates information such as a type of the energy source, energy output limits, electric current limits and information such as an energy demand profile of the vehicle. Also included is an interface between the Battery Management System and Charger Control System.

A connector assembly is provided with a housing forming an exterior, an inlet end, a cavity, and an outlet end. The housing has a recess formed within the exterior and at least one aperture formed through the housing within the recess for venting the cavity. A cord extends through the inlet end into the cavity. The first housing portion has a first fastener mechanism formed within the cavity. The second housing portion is provided with a second fastener mechanism sized to extend into the first housing portion cavity for engagement with the first fastener mechanism to fasten the first housing portion and the second housing portion together. A molded material is disposed within the cavity for engaging the fastened first and second fastener mechanisms for minimizing unfastening of the first and second fastener mechanisms. Retainers are provided for cords of varying thicknesses.

Embodiments discussed herein refer to electric vehicle charging ports having integrated contactless communication units (CCUs). The electric vehicle charging ports include male and female connector assemblies that can be coupled together in a manner that enables consistent and reliable operation of contactless communications and power transfer. The connector integrates power and alignment such that when two connector assemblies are coupled together, power connections are made in combination with establishing contactless communications links between counterpart CCUs in both connector assemblies. The fixed alignment of the connector assemblies ensures that contactless communication channels, spanning between the connector assemblies, are aligned to enable consistent and reliable operation of contactless communications. The CCUs, which conduct contactless communications, may be integrated in the connector assemblies at fixed positions that enable CCUs of one connector assembly to be aligned with CCUs of another connector assembly when they are coupled together.
