Background technology:
Instrument in the starting of automobile, the car, illumination, sound equipment power consumption equipment all by the in-vehicle secondary battery power supply, just need to charge to it loss of electric energy supplement after the storage battery electric energy discharges.Usually generator will begin to charge a battery behind the engine start, and the battery light on the instrument will knock out, and the belt that connects between generator and bent axle no matter car stops and goes is not bad, and engine one work will charge a battery.This kind mode is simply easy, but when vehicle was motionless, engine idle, generator also can charge to storage battery, but electric current is lower, and the waste fuel oil, and engine also is no advantage.On the other hand, when the storage battery over-discharge can, be easy to make the voltage of storage battery sharply to descend, when not reaching the voltage that starts up the car required, automobile engine can't start, must be by external power supply to charge in batteries.Therefore, require automobile to have second source.
Summary of the invention:
The objective of the invention is provides a kind of installation, easy to use for the prior art weak point, saves oil consumption, keeps the automobile storage battery charging system that utilizes solar recharging of accumulator electric-quantity at any time.
The objective of the invention is to realize by following measures: a kind of automobile storage battery charging system that utilizes solar recharging, it comprises storage battery, cigar lighter, it is characterized in that: also have the photovoltaic array cell panel, the DC-DC converter; Described photovoltaic array cell panel is connected with DC-DC converter input through K switch 1, and the DC-DC converter output terminal is provided with K switch 2, K3 and connects respectively storage battery and cigar lighter input, and the cigar lighter output is connected with the storage battery source.
Described DC-DC converter is by filter, high frequency transformer, output rectifier, current detection circuit, voltage detecting circuit, the temperature detection loop, control circuit forms, described high frequency transformer is connected between filter and the output rectifier, filter and photovoltaic array cell panel output join, output rectifier is exported termination K switch 2 side by side, K3, described current detection circuit is connected between filter output and the control circuit, voltage detecting circuit two inputs are connected on respectively K switch 2 and storage battery, on the connection line of K3 and cigar lighter, voltage detecting circuit output access control circuit, temperature detection loop input termination is arranged in the temperature sensor at storage battery and high frequency transformer place, temperature detection loop output termination control loop, control loop connects high frequency transformer.
Compared with prior art, the automobile storage battery charging system that utilizes solar recharging that has adopted the present invention to propose, have following advantage: 1) native system only needs external solar panel and transformation of electrical energy unit to get final product on the basis to the original structural modification of automobile not.The needed solar panel of system generally is placed on vehicle roof, can take full advantage of the topside area of vehicle, both can reach attractive in appearance, can not affect again other normal use of automobile.The transformation of electrical energy unit is placed on automobile trunk, is connected to positive and negative poles of battery by lead-in wire.2) native system both can use in motor racing, also can use when stationary vehicle, facilitated and used maximization.So long as the place of sunlight is arranged daytime, there is not the place utilization of sunlight to deposit electricity, native system can play a role.
