CN201703265U - Solar electric driving system of electric vehicle - Google Patents

The utility model discloses a solar electric driving system of an electric vehicle, comprising a battery, a motor controller and a turbine type motor which are connected in series. The system is characterized in that the system is also provided with a solar panel; the positive electrode output end and the negative electrode output end of the solar panel are connected with a super capacitor and a charging controller in parallel; the positive electrode output end and the negative electrode output end of the charging controller are connected with the positive electrode and the negative electrode of the battery; and the positive electrode of the super capacitor is directly connected with the positive input end of the motor controller by a conducting wire. The utility model has the advantage that the solar energy is absorbed by the solar panel, and then is converted into electric energy, the super capacitor can be quickly charged by the electric energy, and the battery also can be charged; the charged super capacitor can be used for charging the battery in real time, so the battery has no electricity shortage, and the service life is greatly prolonged; the battery and the super capacitor can simultaneously supply the electricity to the turbine type motor, the starting speed and the driving speed can be quickly raised, and the power is strong; and the endurance range is greatly extended.

Technical field

The utility model is particularly related to a kind of electric vehicle solar-electricity drive system.

Background technology

At present, the power drive system of various battery-driven cars all be by battery pack as propulsion source, the wheel motor that drives battery-driven car by electric machine controller realizes the walking of vehicle, as Electrical Bicycle, electro-tricycle, electronlmobil etc.These battery-driven cars without fuel, help environmental protection, the problem of its existence is: 1, the battery charging time long, the limited time of charging back sustained use once, the continuation of the journey mileage is short; 2, storage battery repeated charge, service life is short, and in a single day it is untimely particularly to charge, cause deep discharge can accelerate the aging of storage battery, and the price of battery pack is higher, changes storage battery can improve use cost greatly; 3, because the fluctuation range of battery pack release current is less, can't the big electric current of abrupt release, cause the toggle speed of battery-driven car slow, the speed of a motor vehicle promotes also slow.

Summary of the invention

The technical problems to be solved in the utility model is that a kind of electric vehicle solar-electricity drive system will be provided, this system utilizes solar power and electric energy as hybrid power source, battery pack need not independent charging just can remain in state of charge, the continuation of the journey mileage is long, the battery pack long service life, toggle speed and moving velocity that can the fast lifting battery-driven car.

The electric vehicle solar-electricity drive system that the utility model relates to, comprise series connected successively battery pack, electric machine controller and wheel motor, its special character is: this system also is provided with solar panel, the positive and negative electrode mouth of solar panel is parallel with ultracapacitor and charge controller, the positive and negative mouth of charge controller links to each other with the positive and negative electrode of battery pack, and the positive pole of ultracapacitor and the positive input terminal of electric machine controller are direct-connected by lead.

Above-mentioned electric vehicle solar-electricity drive system is provided with hand switch between the positive input terminal of battery pack positive pole and electric machine controller, drive wheel motor directly to utilize solar panel and ultracapacitor separately, prolongs the service life of battery pack.

Above-mentioned electric vehicle solar-electricity drive system, described solar panel are polylith and series connection mutually.

Above-mentioned electric vehicle solar-electricity drive system, described ultracapacitor is to be in series by a plurality of farad capacitors.

The utility model has the advantages that: this system utilizes solar power and electric energy as hybrid power source, absorb solar energy and be converted into electric energy by solar panel, can carry out fast charge to ultracapacitor, and can charge to battery pack by charge controller; Ultracapacitor after the charging also can make battery pack need not independent charging and just can remain in state of charge by charge controller to the battery pack real time charging, guarantees not power shortage of battery pack, and can prolong greatly the service life of battery pack; Because the positive pole of ultracapacitor is direct-connected by lead with the positive input terminal of electric machine controller, so battery pack and ultracapacitor can be that wheel motor is powered simultaneously, toggle speed and moving velocity that can the fast lifting battery-driven car, powerful; Simultaneously prolonged the continuation of the journey mileage greatly, the continuation of the journey mileage can reach 130KM when fine day is sunny.This system can be installed on the various battery-driven cars such as electro-tricycle, electronlmobil, Electrical Bicycle, and is applied widely.
