Abstract

Disclosed is an apparatus for replenishing energy in a flywheel battery when a bicycle is going downhill. The bicycle is provided with a manual engaging and disengaging device and a motive power assembly (2), wherein the manual engaging and disengaging device controls whether to replenish energy in a flywheel battery (3) according to the state of travel of the bicycle. The motive power assembly receives the driving force of a bicycle rear wheel (72) and replenishes energy in the flywheel battery. The benefit is that in the case of no power source, the bicycle can be used to replenish kinetic energy in the flywheel battery. Manually controlling the time for replenishment of energy in the flywheel battery lightens the manpower load. Thus, when the bicycle is going downhill, the apparatus couples with the bicycle to provide kinetic energy to the flywheel (31). When the bicycle is going uphill or travelling along a flat, the apparatus separates from the bicycle to lighten the manpower load. Using the principle of centrifugal force means that after stopping driving, a drive mechanism can automatically separate from the flywheel to prevent unnecessary wastage of energy from the flywheel.

Description

Device for energizing a flywheel battery when the bicycle is going downhill

The present invention relates to the field of flywheel batteries (or flywheel energy storage devices), and more particularly to a device for replenishing energy of a flywheel battery.

Background technique

Among many energy storage devices, the flywheel battery breaks through the limitations of chemical batteries and uses physical methods to achieve energy storage. When the flywheel rotates at a certain angular velocity, it has a certain kinetic energy, and the flywheel battery is converted into electric energy by its kinetic energy. Compared with chemical batteries, flywheel batteries are expected to be the most promising energy storage batteries due to their high efficiency, short charging time, small relative size, and clean and pollution-free.

The working principle of the flywheel battery: There is a motor (electric/generator integrated machine) in the flywheel battery. When charging, the motor runs in the form of a motor, and the externally input electric energy is converted into the kinetic energy of the flywheel by the electric motor, that is, the flywheel battery is charged. When the outside world needs electric energy, the motor rotates in the form of a generator, and the kinetic energy of the flywheel is converted into electric energy by the generator, and is output to an external load, that is, the flywheel battery is "discharged". In order to reduce wind loss, friction and other energy losses, the flywheel battery is placed in a vacuum box and uses magnetic suspension bearings to support the rotating parts.

The flywheel battery has the characteristics of large energy storage density and relatively small size. It is especially suitable for carrying in the field without power supply. Especially for the riders who ride bicycles, when camping in the wild, it is very necessary to have a laptop computer and a radio. High-powered lights support the flywheel battery of electricity. However, the flywheel battery can only be used to drive the generator in the vacuum box to drive the flywheel to rotate, so that the flywheel stores kinetic energy, but there is no power source in the field to charge the flywheel battery.
