Abstract
The invention discloses a novel electric vehicle charging system with solar power supply. The system comprises a solar battery array and comprises a DC/DC converter, a lithium battery group, a charging protection device, an electric bicycle storage battery, a single chip microcomputer and a driving circuit which are connected with the solar battery array orderly. The driving circuit is also connected with the DC/DC converter. The single chip microcomputer is connected with the solar battery array through a voltage and current sampling circuit. The charging protection device is also connected with the DC/DC converter. According to the voltage and current information obtained through collection, the single chip microcomputer drives the DC/DC converter to output voltage and current of a largest power point to charge the electric bicycle storage battery. When the electric bicycle storage battery is not charged, the solar array charges the lithium battery group to store electric energy through the DC/DC converter, and the charging efficiency of the electric vehicle charging system with solar power supply can be effectively raised. Theoretically, the efficiency of the system is raised by 50% compared with the traditional system, but due to surrounding environment influence and energy loss, the final efficiency can be raised by 20% to 30%.
Description
Technical field
The present invention relates to solar powered technical field, be specifically related to a kind of charging system of electric powercar of new type solar energy power supply.
Background technology
Along with the exhaustion of fossil energy, the development of urbanization, and concern to environment, the mankind are more and more urgent to the demand of regenerative resource, clean energy resource.Vehicle technology is the best approach that replaces fuel oil, gas vehicle, developing direction that also there is no question about.But battery energy storage technology, in the charging interval, battery life is all the bottleneck of its development of restriction.Traditional solar recharging mode is generally connected solar panels with reverse-filling diode with storage battery, start charging.If the voltage of solar panels, lower than the voltage of battery, so just cannot charge.Substantially be all the mode of utilizing constant voltage charge.And the power loss that this mode is brought, developing rapidly with the rapid reduction of electronic device price and seeming more and more uneconomical along with recent microelectric technique.And because solar cell holds at high price, energy conversion efficiency is difficult to the present situation improving, and for solar cell, the efficiency utilization of charge in batteries is seemed to even more important.
Summary of the invention
The present invention, for solving the deficiencies in the prior art, provides a kind of charging system of electric powercar of new type solar energy power supply, can effectively improve the charge efficiency of solar powered charging system of electric powercar.
The technical solution used in the present invention is:
A kind of charging system of electric powercar of new type solar energy power supply; comprise solar battery array 1; the DC/DC converter 2, lithium battery group 3, charging protector 4, electric bike battery 5, single-chip microcomputer 6 and the drive circuit 7 that are connected successively with solar battery array 1; drive circuit 7 is also connected with DC/DC converter 2; single-chip microcomputer 6 is connected with solar battery array 1 by electric current and voltage sample circuit 8, and charging protector 4 is also connected with DC/DC converter 2.
DC/DC converter 2 is for having the converter of voltage raising and reducing function.Its output is equipped with the diode of reverse-filling.Its understands the maximum power point in real-time tracking solar panels, has given play to the maximum effect of solar panels.Voltage is higher, by maximal power tracing, just can export more electric weight, thereby improves charge efficiency.
Charging protector 4 has and is full of electric auto-breaking, and overcurrent-overvoltage power down function.
Lithium battery group is the energy storage component of charging system, and the unnecessary electrical power storage of solar battery array is got up, and in order to overcast and rainy, evening etc., charging was used.
Single-chip microcomputer 6, according to the electric current and voltage information collecting, drives the electric current and voltage of DC/DC converter 2 Maximum Power Output points to charge to battery of electric bicycle.In the time there is no electric bike battery charging, solar battery array passes through DC/DC converter 2 to lithium battery group 3 charging energy-storings.
The invention has the beneficial effects as follows: the present invention has designed the charging system of electric powercar of a kind of new type solar energy power supply that simplicity of design, rationally can effectively improve the charge efficiency of solar powered charging system of electric powercar.Theoretically, this charging system can improve 50% than traditional efficiency, and still, due to surrounding environment influence and various energy loss, final efficiency also can improve 20%-30%.
