Embodiment
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
As shown in Figure 1, first the 48V voltage output end VC3 of 48V storage battery VC1 and 12V storage battery VC2 is installed in electric motor car, and is connected on controller for electric vehicle circuit.K1 is electric motor car key switch, after opening key switch K1,48V direct voltage divides two-way, one tunnel is point two-way after resistance R1 difference, one road is connected to the collector electrode of triode Q1, and another road is connected to the base stage of triode Q1 through resistance R2, and triode Q1 base stage is connected with VD1 voltage-stabiliser tube, voltage-stabiliser tube VD1 makes triode Q1 base voltage clamper at 24V direct voltage, makes triode Q1 emitter export voltage comparator ic 1 circuit supply of 24V direct voltage supply LM358 integrated circuit composition; When 48V storage battery VC1 voltage abundance, under steam, another road 48V direct voltage after key switch K1 connects is connected with one end of resistance R3 one end and 48V relay J 1 in electric motor car.Now, 48V voltage makes 2 pin voltages of voltage comparator ic 1 at about 13V after resistance R3 and resistance R4 dividing potential drop, and 3 pin voltages of voltage comparator ic 1 export 12V voltage after resistance R5 and resistance R6 dividing potential drop, 3 pin voltages of voltage comparator ic 1 are made to remain 12V voltage, after voltage compare is made in voltage comparator ic 1 inside, 1 pin output low level of voltage comparator ic 1, make triode Q2 not conducting, relay J 1 not adhesive, the inner normally opened contact J1-1 of relay J 1 and J1-2 not adhesive, 48V voltage output end VC3 keeps 48V storage battery power supply.
When electric motor car is in long-time traveling, cell voltage can along with electric machine rotation in electric motor car in traveling be to the consumption of battery capacity, cell voltage will decline, when battery capacity voltage sets is about 46V, electric motor car just can not travel, when now battery of electric vehicle voltage is the 46V voltage of setting, the now decline of 48V voltage, 2 pin voltages of the voltage comparator ic 1 after resistance R3 and resistance R4 dividing potential drop are also declined, because 3 pin voltages of voltage comparator ic 1 remain unchanged, now 3 pin voltages of voltage comparator ic 1 are higher than 2 pin voltages, 1 pin of voltage comparator ic 1 is made to export the base stage that 24V voltage is connected to triode Q2 after resistance R7 and resistance R8 dividing potential drop, triode Q2 conducting, relay J 1 obtains electric work, make the normally opened contact adhesive of relay J 1, after normally opened contact J1-1 adhesive, the positive terminal of 12V storage battery VC2 is connected to the negative pole end of 48V storage battery VC1, after normally opened contact J1-2 adhesive, the negative pole of 48V voltage output end VC3 is made to be connected to the negative pole end of 12V storage battery VC2 through the adhesive of normally opened contact J1-2, after making 12V storage battery VC2 connect with 48V storage battery VC1 like this, 48V voltage output end VC3 voltage is made to increase 12V voltage, battery is made to add certain voltage, battery capacity increases relatively, make electric motor car can also continue to travel stretch journey, facilitate electric motor car to drive to fixed location to charge to electric motor car internal cell.
Upper display and describe general principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection range is defined by appending claims and equivalent thereof.
