Abstract

The design is a super capacitance electrically-powered bicycle for traffic, which is introduced with a power supply circuit containing the super capacitance as a drive power supply of an electromotor base on a common electric vehicle, the using of the super capacitance improves the starting performance of the electromotor, thereby improving the service life of the battery and improving the riding performance and effect of the whole bicycle, and the utility model is beneficial to environmental protection and has social and economical benefits.

Description

The super capacitor electric assisted bicycle

One, technical field

The design's super capacitor electric assisted bicycle belongs to the Electrical Bicycle class.

Two, background technology

As everyone knows, Electrical Bicycle (being commonly called as battery-driven car) is exactly that the standard bicycle seat that adds the ordinary people behind holding storage battery and the electrical motor is ridden.The appearance of battery-driven car brings convenience and enjoys for no automobile family, pollutes and threat but also brought to environment.Thousands of battery-driven car scrapped batteries need be dealt carefully with, and society is not only white elephant, also is a great problem.Therefore improve battery age, delay to scrap, seek the particularly substitute of lead-acid battery of storage battery, become the problem that current society, particularly scientific and technological circle extremely pay close attention to.

Three, summary of the invention

In view of Electrical Bicycle when bringing convenience and enjoying to people; an also difficult problem of bringing a large amount of waste accumulator gurrys to handle to society; the design provides a kind of both can improve battery age; be beneficial to environmental protection; can improve its train operation performance again; make it lighter, quick, and under identical ampere-hour number, realize the super capacitor Moped Scooter (being called for short the electric capacity boosted vehicle) of longer travelled distance.The design adopts super capacitor improving startability first, and substitutes lead-acid battery with ferric phosphate lithium cell, and physical circuit is as paying shown in the figure.

Pay figure and be depicted as this electric capacity Moped Scooter motor drive circuit schematic diagram.This boosted vehicle has a direct motor drive power circuit that contains super capacitor, and this circuit is made up of storage battery E, super capacitor C, electrical motor M, diode D, current-limiting resistance R, K switch 1, K2, K3 and inverter N.K1 K2 is an integrated control switch, and K1 is normally closed, and K2 often opens, and K3 is a single control switch.E, M, C three are relation in parallel; Storage battery E closes k2, K3 when open circuit at K1 and by R C is charged, and can open again that K2, K3 are fashionable to realize the combined launch of E+C to M by N at K1, and K1, K3 open K2 fashionable for C through N M is discharged----start.During brake, electrical motor M is recovered among the C by D by the electronic moment regenerating braking energy that transfers generating to.

Because the traditional power storage battery can not satisfy battery-driven car demand (heavy-current discharge can damage battery) to power when startup, acceleration, climbing in aspect significant limitations such as superpower output, fast charge, wide temperature range use and life-spans; The face super capacitor because of its have stored energy big, discharge and recharge that speed is fast, big, the characteristics such as the life-span is long of moment outgoing current, can satisfy preferably battery-driven car start, quicken, during climbing to the demand of power.Being used of this circuit super capacitor C and electrokinetic cell E can be learnt from other's strong points to offset one's weaknesses, both satisfied the startup, acceleration, climbing of battery-driven car requirement to power, avoided the injury of heavy-current discharge again to battery, significant prolongation the service life of battery, also improve the train operation performance of battery-driven car, can allow car run much faster, lighter, the mileage number of being walked is more.

In addition, also be provided with D in the design's circuit, utilize the unilateral conductivity of D to guarantee that car transfers the generating mode of operation to by electronic mode of operation, the regenerated energy of the moment of braking is recovered among the super capacitor C.And the drive current of said electrical motor is pulse high current, and it helps the increase of drive torque, and the waveform of pulse current is a sawtooth wave, and its generation is by means of the adjustment of K1, K2, K3 different conditions.Before address, be that E charges to C when K1 closes when K2 K3 opens; And that K1 K3 opens K2 is fashionable, and C discharges to M through K2 and N---drive, thereby realized that E is by the pulsed drive of C to M; In case of necessity, also can close K3 K2 (K1 opens) simultaneously and become C the independent drive of M is the unite driving of E+C to M, the driving of this moment is relative stable state.Moreover K1 K2 K3 can be manual, also can be according to the demand automatic guidance of the size of speed and startup, climbing, the support of this automatic control circuit that need establish in addition certainly.

This electric capacity boosted vehicle has improved the service conditions of battery because of the use of super capacitor, improves battery life, is beneficial to environmental protection, has more changed the startability of car load and has exercised performance.

Four, description of drawings

Accompanying drawing is the motor drive circuit schematic diagram of the design's electric capacity boosted vehicle.

Five, embodiment

The design's electric capacity boosted vehicle is by power circuit components, super capacitor, the storage battery of special making, and the desired location that is assembled in the battery-driven car car body respectively forms.

This electric capacity Moped Scooter is through development and evidence; it can prolong battery age effectively; help environmental protection; can improve the train operation performance of battery-driven car greatly; can allow car run much faster, lighter, safety; under identical ampere-hour number, travel more mileage number (as this test improve former mileage number 15%), all well and good energy-saving effect is arranged.Therefore the design's electric capacity boosted vehicle has good social, economic benefit.

Claims

1. traffic super capacitor electric assisted bicycle, it is characterized in that this boosted vehicle has a direct motor drive power circuit that contains super capacitor, this driving circuit is made up of storage battery E, super capacitor C, electrical motor M, diode D, current-limiting resistance R, K switch 1, K2, K3 and inverter N; K1, K2 are integrated control switch, and K1 is normally closed, and K2 often opens, and K3 is a single control switch; E, M, C three are relation in parallel; Storage battery E closes K2, K3 when open circuit at K1 and by R C is charged, and can open again that K2, K3 are fashionable to realize the unite driving of E+C to M by N at K1, and K1, K3 open K2 close to for C through N to M discharge-driving; During brake, electrical motor M is recovered among the C by D by the electronic moment regenerating braking energy that transfers generating to.
