The voltage waveform output of Fig. 3 presentation graphs 1 circuit.
The preferred mode that carries out an invention
Referring now to accompanying drawing,, the power supply 10 that is used for cell regenerator and trick charge device 10 comprises the solar cell 12A by 4 series connection, 12B, the solar battery group 12 that 12C and 12D form.Every battery can produce about 0.5 volt output voltage, so the output voltage of solar battery group is 2 volts.
Show another power supply 50 in the drawings, when battery dark surrounds following time it and solar battery group be connected in parallel.
The light intensity that is incident on the battery is depended in the electric current output of solar cell.Under given incident intensity, the electric current that solar cell output is 250 milliamperes.Be higher than 250 MAHs, output voltage drops rapidly.Below 250 milliamperes, output voltage remains unchanged substantially.
The output of solar battery group 12 is loaded on the flyback network of being made up of capacitor 18 and switching transistor 20 by lead 14 and 16.When switching transistor 20 was in conducting state, electric current flow through the core body of the primary coil of transformer 19 with the magnetization transformer from capacitor.Electric current constantly flows into capacitor 18 reaches solar battery group 12 up to condenser voltage maximum output voltage from solar battery group.The voltage at capacitor 18 two ends is by the network measuring that comprises switching transistor 24, switching diode 26 and resistance 28.Reach V when detecting voltage

OffWhen reaching, switching transistor 20 turn-offs, and the voltage flyback of 19 levels 32 of transformer is to a certain numerical value, and this numerical value is determined the turn ratio of primary coil by load that comprises battery (not shown) and diode 34 and transformer secondary output coil to a certain extent.
By selecting suitable turn ratio, can utilize flyback voltage to come the battery of 12 volts, 24 volts or 36 volts is charged.
Flyback voltage makes diode 34 be in forward bias condition and the electric current that transformer 19 secondary inductions produce is delivered to the battery that is connected with 38 with circuit 10 terminals 36.The electric current that is produced is a high-frequency impulse form shown in Figure 2.The waveform of current impulse shown in Figure 2 obtains under 10 Ohmic resistance loads.The rise time of obvious electric current is quite quick, decays to 0 subsequently in the time of about 84 microseconds.The peak value of current impulse is that 60 milliamperes and cycle are 8.333 kilo hertzs.Fig. 3 shows the characteristic of the potential pulse that is produced, and voltage rises to rapidly about 14 volts when switching transistor 20 turn-offs.Potential pulse fall and be zero slowly up to electric current, here voltage descend with exponential form and finally after about 52 microseconds value serve as zero.
The peak current that circuit 10 produces is far longer than the leakage discharge electric current of automobile batteries.Less like this mean charging current just can effectively reduce or remove the sulfide of long-term accumulated on the lead acid accumulator flat board.Therefore the electric current that provides of battery can remain unchanged for a long time and can charge with the heavy current charger.Utilize the present invention that the sulfide deposition on the cell plate is little by little peeled off, thereby can utilize again old and useless battery.

Each element of circuit 10 all is protected in order to avoid be damaged when 38 become polarity opposite with the cell terminal misconnection at terminals 36.When taking place to connect, diode 34 has the element that big surge current passes through and damage regenerator 10 by mistake.The resistance 42 that is provided makes the element of regenerator avoid terminals 36 and 38 and the infringement of the big surge current that produces when connecting of battery polar mistake.Resistance 42 is connected with diode 34 and forward terminals 36.The characteristics of positive temperature coefficient resistor are that resistance obviously increases under relatively low temperature.This variation of resistance is very fast and make electric current drop to the level that circuit 10 various elements can bear.The current strength of bearing of element nominal is 1 ampere.
What protection LED40 avoided big current surge infringement is a plurality of diodes that are cascaded 44, and they and LED40 are connected in parallel.The electric current that these diode pairs are flowed through provides very little impedance.When the terminals misconnection, most of electric currents flow to positive temperature coefficient resistor 42 through diode 44.To solar battery group 12 further protection provide diode 46 to prevent at terminals 36 electric current inflow solar cell during with 38 are connected opposite with cell terminal.
The output of regenerator 10 can be loaded into cell terminal by the plug that inserts cigar lighter on the means of transportation.Under another kind of mode, the output of regenerator 10 also can be loaded into cell terminal by external electric cable and the clip that directly is connected with battery.A kind of connected mode in back may make regenerator output misconnection to pending battery.
