Abstract: A foldable electrically powered vehicle is disclosed. In one embodiment, a foldable electrically powered vehicle includes a foldable chassis frame having members connected using interlocking elements such that the foldable chassis frame is folded by unlocking each interlocking element connecting the members. The vehicle also includes a front fork interlocked with the first member of the foldable chassis frame and a swing arm interlocked with the second member of the foldable chassis frame. Moreover, the vehicle includes a rear fork interlocked with the third member of the foldable chassis frame. The foldable chassis member, the front fork, the rear fork and the swing arm are detached by unlocking respective interlocking elements.

Abstract: An energy storage and generation system for an electrically powered motorized vehicle is disclosed. In one embodiment, an energy storage and generation system for an electrically powered motorized vehicle includes a stator having field coils and sensors which are provided on the inner periphery of the stator, and a rotor having permanent magnets with N and S poles arranged alternately in a circumferential direction on the outer periphery to face the field coils and housing batteries of the electrically powered motorized vehicle. The energy storage and generation system also includes a drive control unit connected to the sensors and the field coils for generating magnetic field in the field coils of the stator in response thereto to rotate the rotor. The rotation of the rotor stores rotational kinetic energy due to the dead weight of the plurality of batteries which is used to propel the electrically powered motorized vehicle.

Abstract: The present invention describes an electric vehicle with hybrid drive system, which provides optimization of speed, power and maximizing efficiency levels. In one embodiment, the vehicle includes at least one driven wheel, an electric motor connected to the driven wheel through a fixed transmission system or a continuous variable transmission (CVT) unit, an internal combustion engine (ICE) connected to the driven wheel through a fixed transmission system or a CVT unit and a selector switch to select the modes of power supply to the electric vehicle. Further, the electric motor is powered by a battery power pack and the ICE is powered by a hydrocarbon fuels stored in a hydrocarbon fuel tank. Furthermore, the different position of selector switch provides different modes of the power supply to the vehicle. In another embodiment, the electric motor is adapted to be operated as a generator.
