Summary of the invention
For overcoming the deficiency of existing automobile starting supply unit, this utility model devises a kind of automobile starting supply unit.
In order to solve the technical problem of above-mentioned existence, this utility model have employed below scheme:
A kind of automobile starting supply unit, start the moving together contact of motor including automobile storage battery, bank of super capacitors, automobile electromagnetic and start motor DC motor, automobile electromagnetic is connected in parallel between the both positive and negative polarity of automobile storage battery with bank of super capacitors after starting the moving together contact of motor and starting the series connection of motor DC motor again, it is characterized in that: also include that inductance and diode, inductance and Diode series are connected between automobile storage battery and bank of super capacitors.
Further, inductance and Diode series are followed by between the positive pole and bank of super capacitors positive pole of automobile storage battery.
Further, bank of super capacitors includes the ultracapacitor that some connection in series-parallel connect.
In the case of normal startup, automobile starting is completed by the energy storage of bank of super capacitors completely, after starting unsuccessfully when indivedual difficult startup, then through inductance coil, bank of super capacitors is charged by the automobile storage battery of same external connection, then carried out automobile starting by the energy storage of bank of super capacitors+accumulator.
This automobile starting supply unit has the advantages that
(1) this utility model avoids the starting current big during automobile starting impact to automobile storage battery, the startup energy major part of bank of super capacitors is that automobile current generator directly charges simultaneously, decrease the charge and discharge cycles of automobile storage battery, add starting efficiency simultaneously.
(2) in this utility model, a number of ultracapacitor connection in series-parallel composition bank of super capacitors, automobile can be met and completed automobile starting by bank of super capacitors under normal circumstances.Diode ensure that the voltage of bank of super capacitors is higher than automobile storage battery a few volt voltage, it is ensured that electric energy, to bank of super capacitors one-way flow, also ensure that the special power supply of bank of super capacitors.Inductance can neither affect and charge bank of super capacitors, prevent again bank of super capacitors current potential relatively low or without powering up generation heavy current impact in the case of current potential, can not suddenly change owing to flowing through the electric current of novel inductor, so ensureing to provide by bank of super capacitors C at automobile starting moment major part electric current.
(3) this utility model adds inductance in start-up circuit, is lost little, and efficiency is high；In start-up course, it is ensured that Vehicular accumulator cell is rationally got involved, reduce the requirement starting super capacitor, it is ensured that the reliability of starting, avoid again the High-current output infringement to accumulator simultaneously.
(4) this utility model simple in construction, using effect is good.

Detailed description of the invention
Below in conjunction with the accompanying drawings, this utility model is described further:
Fig. 1 shows a kind of automobile starting supply unit, starts moving together contact K of motor including automobile storage battery E, inductance L, diode D, bank of super capacitors C, automobile electromagnetic and starts motor DC motor M.Automobile electromagnetic is connected in parallel between the both positive and negative polarity of automobile storage battery E with bank of super capacitors C after starting moving together contact K of motor and starting motor DC motor M series connection again.Inductance L and diode D connects and is followed by between the positive pole and bank of super capacitors C positive pole of automobile storage battery E.
The series arm of the positive pole of bank of super capacitors C, the negative pole of bank of super capacitors C, inductance L and diode D does not connects one end of bank of super capacitors C, for three points of this utility model Yu external connection.When specifically applying, inductance L externally connects the positive pole of automobile storage battery E, bank of super capacitors C positive pole externally connects automobile electromagnetic and starts moving together contact K of motor, start moving together contact K of motor through automobile electromagnetic to power to starting motor DC motor M, the negative pole of bank of super capacitors C externally connects the negative pole of automobile storage battery E, and the negative pole of bank of super capacitors C externally connects automobile electromagnetic and starts the d.c. motor M of motor.
After automobile starting, the two ends charging voltage of automobile storage battery E typically high several volts of rated voltage than automobile storage battery E, after automobile engine is stopped transport as seen from Figure 1, the voltage of bank of super capacitors C is that automobile storage battery E two ends charging voltage deducts diode drop, and considering the internal resistance of automobile storage battery E, electromagnetic type automobile starts the lowest starting voltage of motor less than a few volt of automobile storage battery rated voltage under normal circumstances.The energy storage of the charging voltage at bank of super capacitors C two ends, the difference of the energy storage of the lowest starting voltage corresponding with bank of super capacitors C, it is simply that the startup energy of bank of super capacitors C.So, rationally select a number of ultracapacitor connection in series-parallel composition bank of super capacitors C, automobile can be met and completed automobile starting by bank of super capacitors C under normal circumstances.Diode D ensure that the voltage of bank of super capacitors C is higher than automobile storage battery E a few volt voltage, ensures that electric energy, to bank of super capacitors C one-way flow, also ensure that the special power supply of bank of super capacitors C.Inductance L chooses appropriate value, can neither affect and bank of super capacitors C is charged, prevent again bank of super capacitors C current potential relatively low or without powering up generation heavy current impact in the case of current potential, can not suddenly change owing to flowing through the electric current of novel inductor L, so ensureing to provide by bank of super capacitors C at automobile starting moment major part electric current, when after automobile starting 1 second, bank of super capacitors C storage electric energy is finished, at this moment by automobile storage battery E steady electricity supply, the impact to automobile storage battery E of the relatively great start-up current of automobile starting is so prevented.The internal resistance of bank of super capacitors C is compared the least with battery, improves the startability starting motor.Bank of super capacitors C starts motor moving together contact K through automobile electromagnetic and specially powers d.c. motor M, it is to avoid automobile engine is excessively used the energy of automobile storage battery E and causes automobile in the case of stopping transport can not start the situation of electrical injuries big with accumulator to be occurred.
Above in conjunction with accompanying drawing, this utility model is carried out exemplary description; obvious realization of the present utility model is not subject to the restrictions described above; as long as have employed the various improvement that method of the present utility model design is carried out with technical scheme; or the most improved design of the present utility model and technical scheme are directly applied to other occasion, all in protection domain of the present utility model.
