The driving circuit is further connected with the DC/DC converter. The single chip microcomputer is connected with the solar energy battery array through a voltage and current sampling circuit. The charging protection device is further connected with the DC/DC converter. The single chip microcomputer drives the DC/DC converter to output voltage and current of the maximum power point to charge the electric bicycle storage battery according to collected voltage and current information. When the electric bicycle battery is not charged, the solar energy battery array carries out charging and energy storage on the lithium battery group through the DC/DC converter. The charging efficiency of the electric vehicle charging system powered by solar energy is effectively improved. In theory, the efficiency of the charging system is improved by 50% compared with the traditional efficiency. Due to the impact of the surrounding environment and various energy losses, the final efficiency can be improved by 20% to 30%.
Description
Technical field
The utility model relates to solar powered technical field, is specifically related to a kind of solar powered charging system of electric powercar.
Background technology
Along with the exhaustion of fossil energy, the development of urbanization, and to the concern of 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 the battery energy storage technology, in the charging interval, battery life is all the bottleneck of its development of restriction.Traditional solar recharging mode generally is connected solar panels with the reverse-filling diode with storage battery, begin charging.If the voltage of solar panels lower than the voltage of battery, so just can't charge.Basically 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, the present situation that energy conversion efficiency be difficult to improve seems even more important for solar cell to the efficient utilization of charge in batteries.
The utility model content
The utility model provides a kind of solar powered charging system of electric powercar for solving the deficiencies in the prior art, can effectively improve the charge efficiency of solar powered charging system of electric powercar.
The technical solution adopted in the utility model is:
A kind of solar powered charging system of electric powercar; comprise solar battery array 1; is connected successively 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 connects with solar battery array; drive circuit 7 also is connected connection with the DC/DC converter; single-chip microcomputer 6 is connected connection by electric current and voltage sample circuit 8 with solar battery array, charging protector 4 also is connected connection with the DC/DC converter.
The converter of DC/DC converter 2 for having the 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 the overcurrent-overvoltage power down function.
The 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 is according to the electric current and voltage information that collects, and the electric current and voltage that drives DC/DC converter 2 Maximum Power Output points charges to battery of electric bicycle.When there is no the electric bike battery charging, solar battery array passes through DC/DC converter 2 to lithium battery group 3 charging energy-storings.
The beneficial effects of the utility model are: the utility model has designed a kind of solar powered charging system of electric powercar, and 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 efficient, and still, due to surrounding environment influence and various energy loss, final efficient also can improve 20%-30%.
