A system for maintaining battery cycle life for motorized battery-powered electric vehicles. Current battery-powered electric vehicles such as automobiles and trucks suffer from short cycle life of their batteries, meaning that these vehicles' batteries will become unusable well before reaching the normal useful life of combustion engine powered vehicles. Owners of vehicles using my system will enjoy vehicles with acceptable ranges, acquisition and operating costs, yet will enjoy battery lifetimes as long or as longer than the useful life of combustion engine vehicles.

A battery system for an electric motor vehicle comprises first and second battery cartridges that are installed in corresponding first and second battery compartments of the electric motor vehicle. The first battery cartridge has a power connector port with at least one of a shape, size, configuration and orientation that is different than the corresponding power connector port of the second battery cartridge. The first and second battery compartments are physically spaced apart and electrically coupled together by a bridging power cable. The bridging power cable comprises first and second connector ends that extend respectively into the first and second battery compartments, and the first connector end mates more easily with the first power connector port than with the second power connector port, and the second connector end mates more easily with the second power connector port than with the first power connector port.

To provide a vehicle drive device capable of efficiently driving a vehicle by using a motor without falling into the vicious cycle between enhancement of driving via the motor and an increase in vehicle weight. The present invention is a vehicle drive device (10) having a motor for driving the wheels of a vehicle and includes a front wheel motor (20) for driving front wheels (2b) of a vehicle (1) and a battery (18) and a capacitor (22) that supply electric power for driving the front wheel motor (20), in which the voltage of the battery (18) and the capacitor (22) connected in series is applied to the front wheel motor (20) and the capacitor (22) is disposed between the left and right front wheels (2b) of the vehicle (1).

A hybrid driving apparatus includes an internal combustion engine, a motive power transmission mechanism transmitting a driving force to main driving wheels, a main driving electric motor generating a driving force of the main driving wheels, an accumulator, sub-driving electric motors generating driving forces of sub-driving wheels, and a control apparatus executing an electric motor traveling mode and an internal combustion engine traveling mode. The sub-driving electric motor is provided to each of the sub-driving wheels, the control apparatus causes only the main driving electric motor to generate the driving force in the electric motor traveling mode and causes the main driving electric motor and the sub-driving electric motors to generate the driving forces in acceleration of the vehicle at a predetermined vehicle speed or higher, and although the engine generates the driving force, it does not cause the motors to generate driving forces in the traveling mode.

The present disclosure relates to an energy storage compartment connectable between a pair of longitudinally extending frame rails of a heavy-duty vehicle, the energy storage compartment being arranged to house an energy storage system configured to supply energy to a prime mover of the vehicle for propulsion of the prime mover, wherein the energy storage compartment comprises longitudinally extending portions forming an encircling load absorbing module, the longitudinally extending portions comprising a pair of longitudinally extending side wall portions connectable to the pair of longitudinally extending frame rails, a longitudinally extending floor portion and a longitudinally extending roof portion, wherein the longitudinally extending portions of the encircling load absorbing module are arranged and configured to, when being subject to a load from the longitudinally extending frame rails, absorb the transversal component of the load.

A motorcycle includes an electric motor having an output shaft defining a motor axis, a rear wheel drivably coupled to the electric motor to propel the motorcycle, a swingarm rotatably supporting the rear wheel, and a frame. The frame includes a main frame member supporting the electric motor and the swingarm. A case of the electric motor is a stressed member of the frame between the main frame member and the swingarm. The swingarm is coupled to the case of the electric motor to define a swingarm pivot axis that is co-axial with the motor axis.

A modular battery pack for mounting to a vehicle frame of a vehicle. The modular battery pack comprising a plurality of modules arranged adjacent to each other, wherein at least one module constitutes an electrical energy storage module. Each module comprises first and second opposite side walls arranged to face respective side walls of adjacent modules, and to provide structural integrity of the modular battery pack. Each side wall comprises a common set of interfaces for interfacing between adjacent modules. The modular battery pack also comprising at least one control unit having a side wall comprising the common set of interfaces, and also a vehicle interface for interfacing with the vehicle.

A locking device for locking an energy supply unit of a bicycle including a holding element. The locking device configured to lock the energy supply unit to the holding element in a locking position, and for separation of the energy supply unit from the holding element, to permit movement of the energy supply unit from the locking position to an intermediate position, and to release the energy supply unit, disposed in the intermediate position, when the energy supply unit is to be separated from the holding element. The locking device includes a guide element adjustable between a clamping position, in which a clamping force is applied along a clamping direction to the energy supply unit, and a release position, in which movement of the energy supply unit from the locking position into the intermediate position along a direction of movement extending at an angle to the clamping direction.

A vehicle chassis platform including: a frame having a front frame end, a rear frame end, a longitudinal frame axis, an upper frame surface, a bottom frame surface, a first longitudinal lateral frame surface and a second longitudinal lateral frame surface, wherein the upper frame surface is substantially flat; and two or more mechanical connectors each on one of the first and second longitudinal lateral surfaces, each of mechanical connectors to couple a vehicle corner module (VCM) to the frame and to transfer mechanical loads between the frame and the VCM when the VCM is on the frame.

The disclosure is directed at a method and apparatus for an active convertor dolly for use in a tractor-trailer configuration. In one embodiment, the apparatus includes a system to connect a tractor to a trailer. The apparatus further includes a charge generating system for translating the mechanical motions or actions of the dolly into electricity or electrical energy so that this energy can be used to charge a battery or to power other functionality for either the dolly or the tractor-trailer. The active dolly may also operate to assist in shunting the tractor-trailer.
