The present invention has overcome the deficiencies in the prior art part, has the electric energy that the renewable sources of energy of electronlmobil are changed all to be reclaimed, and can increase the characteristics of its continual mileage greatly, is mainly used in electronlmobil or renewable sources of energy special electric car chassis.
Description of drawings
Fig. 1 is battery-driven car energy recovery control circuit figure of the present invention; Fig. 2 is a renewable sources of energy special electric car chassis structural representation of the present invention.
The specific embodiment
Battery-driven car energy recovery control circuit figure as shown in Figure 1.Control circuit Q1, the permanent-magnet magnetic resistance motor A that constitutes by microcomputer and DMOC645 electricity speed setting controller (U.S. sun electricity company), be connected on contactless switch J2, J1 in the motor circuit, the counterpart that is serially connected in contactless switch J3, diode D1, D2 and the existing battery-driven car energy recovery control circuit in the electrical generator loop is identical.Control circuit Q1 mainly is responsible for function program controls such as speed governing, drag, energy recovery.Permanent-magnet magnetic resistance motor A both can be used as electrical motor, can be used as electrical generator again.Different is to adopt high and low voltage charging branch road.Wherein, high-voltage charge props up route battery pack F1, DC diode D3 and high capacity ultracapacitor C1 and constitutes, and battery pack F1 is with in parallel with cond C1 again after diode D3 oppositely is connected in series.The low voltage charging paths is made of battery pack F2 and capacitor C 2, is conventional battery charging circuit.Be connected in the electrical generator loop after the parallel connection of high and low voltage charging branch road.Dc inverter booster circuit Q2 is made up of 5KVA inverter (the new following company in Shenzhen produces), is connected between low voltage charging paths and the high-voltage charge branch road.Key of the present invention is the employing of high capacity ultracapacitor and low voltage charging paths and dc inverter booster circuit.High capacity ultracapacitor C1 is homemade A type 450V, 6 of the big electric capacity of 0.5F and uses, the electric energy of the conversions such as the renewable sources of energy of the big electric current (more than the 200A) of instantaneous generation, high potential (more than the 200V) all can be deposited earlier among this cond C1, and then pass through diode D3 slowly to storage battery F1 charging, this part electric energy is all reclaimed.The low voltage charging paths can be earlier be recovered to the electric energy of those low voltages (being lower than the following voltage of power supply), little electric current (10A is following) earlier among the storage battery F2, just boost through dc inverter booster circuit Q2 after reclaiming abundant electric energy then among the storage battery F2, charge to storage battery F1 through diode D4 rectification again, this part electric energy is all reclaimed.
The chassis as shown in Figure 2.Crossbeam 1 and be fixed on propons 7 on the crossbeam 1, back axle 13, wheel 9, storage battery 12,2, A-battery 3, permanent-magnet magnetic resistance motor 6, change speed gear box 4, compressor 8, direction machine 10, drag vapour irritate 11 and between the position relation all corresponding identical with existing electric automobile chassis.Control circuit Q15 mainly is responsible for function program controls such as speed governing, drag, energy recovery, and it is installed in above the anterior crossbeam of vehicle frame.Different is, the left side that battery pack F1 in the high-voltage charge branch road and high capacity super capacitor group C112 is installed in frame beam 1 is the top of Fig. 2, the right side that part battery pack F22 in the low voltage charging paths is installed in frame beam 1 is the bottom of Fig. 2, the rear portion that the battery pack F22 of remainder is installed in frame beam 1 is the left side of Fig. 2, makes the whole electric automobile chassis keep balance in the design.
The present invention is two extreme (big electric current, high potentials when solving energy recovery; Little electric current, low voltage) electric energy that produces, adopted high and low voltage charging branch road, be that the high-voltage charge branch road is the operating voltage that can satisfy traction electric machine, can satisfy the voltage hybrid battery group of strong storage again, it quickens, in time supplies with big electric current and stable voltage to alleviate the load of conventional accumulators by super capacitor C1 during climbing to battery-driven car, prolongs its life-span.Mainly be to bring into play the mutual supplement with each other's advantages of function separately in conjunction with adapted like this, solve the indeterminable problem of single storage battery.The low voltage charging paths is hybrid battery group F2, the capacitor C 2 that is lower than motor operating voltage, its main task is exactly that the electric energy that will be lower than battery pack F1, capacitor C 1 voltage constantly collects, handle by dc inverter booster circuit Q2 then, with the low pressure inversion boosting, behind battery pack F1 nominal voltage, carry out the voltage stabilizing rectification, charge to battery pack F1 through diode D4.
Overall process is when unclamping foot throttle K, control circuit is according to the program of setting, with contactless switch J2, disconnect, contactless switch J3 adhesive at this moment electronlmobil is to be in deceleration regime also in operation, begins generating, what send is high potential, big electric current, through contactless switch J3 contact diode D1 to super capacitor C1 charging simultaneously sub-fraction to storage battery F1 (super capacitor C1 can accept big electric weight greater than 200A-450V in moment).After the deceleration, the electric weight that capacitor C 1 is stored into slowly carries out constant charge to battery pack F1 again through diode D3.
When the speed when car slides hypomere was lower than 30Km/h, electric current was also little, and voltage is also low, at this moment, through recuperator, adjustment, electric current charge to capacitor C 2 and battery pack F2 through contactless switch J3, diode D1, some capacitor C 1 also receives, but can not enter battery pack F1.The voltage ratio battery pack F1 of battery pack F2 is much lower, can send battery pack F1 in order to make this part energy, the energy recovery controller raises voltage greater than battery pack F1 through rectifying and voltage-stabilizing through inversion with the voltage of battery pack F2, charges to battery pack F1 through diode D4.Car is as long as the accumulator that operation battery pack F2 and capacitor C 2 are formed can non-stoply charge to battery pack F1 through the inversion boosting rectification.
Electronlmobil needs to go up a slope, when overtaking other vehicles, need to give the big electric current high potential of motor A, conventional accumulators does not satisfy this condition, but super capacitor C1 can bear, when foot throttle was strengthened, control circuit Q1 can access big electric current through diode D3, contactless switch J1 from capacitor C 1 and give motor A through contactless switch J2.When overtaking other vehicles or go up a slope end, when not needing big electric current pushing motor, via controller is adjusted the electric energy that battery pack F1 is continued to use in the back.Like this, the both perfect function of electronlmobil has been protected not overload of common charging accumulator again, increases the electronlmobil continual mileage.
