Abstract: A battery electric vehicle provided in the present invention comprises a vehicle body having wheels, an electric motor, an electric generator, and an electricity management device. The electric motor and the electric generator are connected to different wheels of the vehicle body respectively. The electric generator generates electricity by converting the rotational kinetic energy of the wheel into electrical energy. The electricity management device includes a management and controlling member, a detecting member, and a plurality of battery packs. The management and controlling member controls at least one of the battery packs to provide electricity to the electric motor by electrically connecting the electric motor, while the management and controlling member controls at least one battery pack of other battery packs to be charged by receiving the electricity generated by means of electrically connecting to the electric generator.

Abstract: A road automatically dividing apparatus comprises a ground-embedded base, a telescopic tube set, an illuminating device, and a driving device. The ground-embedded base includes an accommodating space and an upper opening. The telescopic tube set, disposed in the accommodating space, includes a plurality of translucent column tubes which are connected telescopically and are relatively slidable in such a manner that each translucent column tube is converted between an expanding position and a collapsing position. The expanding position allows each translucent column tube expand from the neighboring one by sliding relatively to each other. The illuminating device is for emitting light penetrating the telescopic tube set. The driving device is configured to drive the telescopic tube set such that the telescopic tube set expands and collapses between the expanding position and the collapsing position.
