The specific embodiment
Below in conjunction with accompanying drawing the utility model electricity generating and energy storing system for hybrid vehicle is described in further detail.
As shown in Figure 1 and Figure 2, the utility model electricity generating and energy storing system for hybrid vehicle: comprise power car driving engine 1, magneto alternator 2, power car drive motor 3, magneto alternator 2 is provided with high speed winding and low speed winding two-way winding, and in light load low regime and heavy load high velocity generating usefulness, high speed winding and low speed winding are carried out conversion automatically by the operation conditions that an electricity generating controller 4 detects at that time respectively.Power car drive motor 3 is provided with the energy storage capacitor 5 of high-power low capacity by electric machine controller 6 controls between electricity generating controller 4 and electric machine controller 6, energy storage capacitor 5 is used for storing the inertia kinetic energy of car retardation and glancing impact recovery.Electric energy major part from electrical generator 2 directly drives power car drive motor 3 through electric machine controller 6 without energy storage capacitor, to reduce the loss of electric energy in charge and discharge process.Wherein the low speed winding of magneto alternator 2 be connected at a high speed and adopt " Y " type connection.Two groups of coils of magneto alternator 2 are the polyphone connection during low speed generating, and the output line of drawing is totally 6 terminals, exports the three-phase coil terminal of low speed winding and high speed winding respectively.The automatic conversion of high speed winding and low speed winding is provided with a high low speed winding change-over circuit, and change-over circuit comprises pair of contact or a high-pressure electronic switch and the three phase rectifier bridge circuit of a high-pressure vacuum switch.Power car driving engine 1 can be low power combustion vapour driving engine or other engine fuels.
Wherein the function of electricity generating controller can realize following function:
One rectification and precharging circuit: the voltage approaching zero of energy storage capacitor in use first or after discharging fully lies prostrate, because the internal resistance of electric capacity is extremely low, electrical generator is equivalent to load short circuits, therefore need carry out precharge first to electric capacity, method is to pass through the capacitor C current limliting with the mains ac power supply, charges to energy-storage capacitor after the ZL3 rectification again.In the travelling of vehicle at ordinary times every day, be not need to carry out preliminary filling, because the self-discharge of energy storage capacitor is very low, voltage all can remain on the normal range of operation of electric machine controller when started vehicle every day first, unless vehicle will keep in repair and need park voltage for a long time and just can be low to moderate below the normal working voltage value of electric machine controller, just at this moment need by civil power precharge.
It two can come the driving power of controlling and driving motor by detecting the speed of a motor vehicle.As Fig. 3, in order to ensure the low speed high pulling torque in when starting, the driving power of motor is linear ascendant trend and reaches peak value at the fundamental frequency point of motor in the 0-22km/h section, rise and gradually descend then along with the speed of a motor vehicle then, until being close with generated output power, the benefit of doing like this is to have effectively utilized the energy that energy storage capacitor is stored, and cooperates with the change curve of the speed of a motor vehicle with the energy storage capacitor voltage of Fig. 4, can obtain excellent control effect and electric energy control precision.ZL1 can export the vdc above cond rated operational voltage several times during the high engine speeds generating, but because high-pressure vacuum switch is off-state, does not therefore have electric current output.Vehicle is at descending, stops, and braking waits under the situation of power demand not, and ECU control driving engine enters idling mode, keeps minimum fuel oil consumption.According to above-mentioned principle, when no matter driving engine and electrical generator are unloaded, underloading or heavy duty, operate in the higher operating mode of efficient all the time.
Wherein magneto alternator 2 has the winding of two polyphones, its high speed winding current is big, the low speed winding current is little, its principle is: two winding polyphones connect the raising output voltage during low speed, only use the high speed winding of big electric current during high speed, though this moment, the low speed winding produced higher voltage, owing to too high voltage is isolated in the disconnection of K1 vac switch.
The efficient of magneto alternator is than the electrical generator height of other types, but the occasion that is used in variable speed generation just must adopt the variable frequency control inversion transformation technique to convert alternating current to direct current, this has obviously increased the cost of system, the this paper that compares simultaneously directly uses three-phase bridge rectification circuit, has also reduced the generating conversion efficiency.This paper selects two operation points according to the universal curve of combustion engine, and one is the low regime of vehicle low load region, and at this moment generator windings is together in series, and makes electrical generator still can export sufficiently high voltage at slow speed of revolution and uses to drive system.The power that vehicle consumes in accelerator obviously increases, and at this moment high-pressure vacuum switch K1 disconnects ZL1 output, and ECU control driving engine raises speed to high velocity, exports big electric current and gives drive motor.Reasonably select low speed and high velocity, can obviously improve the economy of fuel oil.
The conversion of high low speed winding: electricity generating controller is changed high low speed winding automatically by detecting operation conditions at that time.The high-low pressure winding that the concrete method of implementing is a magneto alternator divides system through ZL1 and the output of ZL2 three phase rectifier, when engine operation during at slow speed of revolution, because the output voltage of ZL1 is lower than the voltage on the energy storage capacitor, therefore ZL1 does not have electric current output, and electrical generator low speed winding and high speed windings in series, therefore the output voltage after the ZL1 rectification enough charges to energy storage capacitor. because the rated current of low speed winding is less, therefore ZL1 output is only bought car in installments to generate electricity when a low speed small power moves and is used. and quicken the heavy load operating mode when vehicle enters, because current draw increases the magnitude of voltage that causes on the energy storage capacitor and descends, ECU is by the given value of foot controller driving torque that the speed of a motor vehicle and load setting value are promptly sampled in electricity generating controller, the throttle given value of control driving engine increases, turn-off the K1 high-pressure vacuum switch simultaneously, the rotating speed of driving engine is the paramount rotating speed of rising district rapidly, this moment, the magnitude of voltage of ZL2 raise, and exported the frequency converter part that big electric current also directly flows to electric machine controller.The size of electric current is constantly sampled to capacitance voltage, the speed of a motor vehicle by ECU, and adjusts engine speed by the inverse feedback that control circuit forms, and keeps the variation of the magnitude of voltage on the electric capacity.
As Fig. 4, the change curve of the energy storage capacitor voltage and the speed of a motor vehicle, its principle of work is that energy storage capacitor voltage should be low more when high more for the speed of a motor vehicle, reason is that the kinetic energy of the high more vehicle storage of the speed of a motor vehicle is many more, therefore energy storage capacitor need discharge more energy could be when car brakeing recuperated energy more effectively, as shown in the formula:
Vehicle reclaims kinetic energy (W.H)=1/2GV
2/ 3600*K
Energy storage capacitor energy (W.H) (=1/2C (Vh
2-Vl
2)/3600
Wherein Vh is energy storage capacitor high potential, and Vl is the energy storage capacitor minimum voltage, and K is the convesion factor that kinetic energy is converted into electric energy, and according to a large amount of actual tests, K is between the 0.6-0.65.
As Fig. 5 is the universal curve figure of a representative type small power motor, from its rotating speed and torque curve, the rate of consumption of fuel oil is regional minimum at 160Nm, and is comparatively speaking should the zone discharging also lower, but to be in operation be impossible keep to be operated in this ideal region to common vehicle.In this article, our design-calculated double speed electrical generator, vehicle low speed or at the uniform velocity during the miniwatt operation, engine operation is at low speed optimal economic loading zone, the driving engine of different model and performance has different speed ranges; Vehicle is quickening and is consuming when more high-power, and the rapid speedup of driving engine is to the high-power district of high speed, and meanwhile high-pressure vacuum switch among Fig. 2 or electronic switch K1 disconnect, and the electrical generator outgoing current is exported high-performance direct current (DC) through the L2 winding.
The utility model and another difference of common series pattern are the electric energy that produces when having adopted the very high energy storage capacitor of efficient to store the motor regenerative brake; In the city of standard operating mode pattern, expenditure of energy about 50% is arranged on the kinetic energy that vehicle quickens, common bus is to have transferred this part energy to heat exhaustion by brake system at glancing impact, and general hybrid vehicle also is to store the electric energy that motor reclaims with various batteries, but because battery is to rely on chemical reaction to store electric weight, exist the internal resistance height, the problem that efficient is low and service life is short adopts performance-oriented energy storage capacitor thoroughly to solve this problem.

2, vehicle start quickens:
Driving engine will change the rotating speed of driving engine according to the detection signal of electric machine controller when vehicle start quickens, electric machine controller detect and computing at that time the energy storage capacitor charge value and the speed of a motor vehicle and chaufeur to the command value of throttle voltage, the rotating speed of automatic compensation driving engine, come when more on the low side in the corresponding speed of a motor vehicle of the electric weight of brish acceleration and capacitor storage, driving engine with speedup to the high-power district of high speed, the big electric current of electrical generator output this moment, driving engine is the economic speed district operation during by maximum power, drive motor obtains electric energy from electrical generator and energy storage capacitor simultaneously, therefore can satisfy the accelerating power of vehicle fully.
3, travel at the uniform speed:
After the speed of a motor vehicle reached predetermined value, accelerator finished, and at this moment because the consumption of energy significantly reduces, electricity generating controller will be controlled driving engine and enter low regime operation, the electric power that electrical generator output is less relatively; The regulating action of electricity generating controller makes electrical generator can satisfy the expenditure of energy of city bus at low speed or high-speed cruising fully.
4, run slowly:
Vehicle runs into obstacle or is about to arrive at a station in the time of need running slowly, and chaufeur can be totally released foot throttle, and at this moment electric machine controller will be controlled the engine idle operation, and vehicle is sliding state.
5, brake snub:
Brake snub and emergency braking are distinguishing, the purpose of brake snub be control vehicle from higher car retardation to the lower speed of a motor vehicle, or stop slowly again after wishing to make vehicle operating one segment distance with less braking force, therefore electric machine controller can detect this signal by also closing of brake pedal, instant control driving engine enters idling mode, electrical generator does not have electric current output, electric machine controller makes motor transfer generating state to by driving condition, the inertia of vehicle can promptly transfer DC current to by motor and electric machine controller and be stored in the energy-storage capacitor, for starting-up to speed next time provides energy conservation.
6, emergency braking:
When dangerous obstacle is met in vehicle operating the place ahead, chaufeur is stepped on brake pedal rapidly, at this moment electric braking and mechanical type compressed air brake play a role simultaneously, and vehicle can stop rapidly, and safety is also more safer than the single mechanical type compressed air brake better effects if of common vehicle.
No matter vehicle operating is in which kind of operating mode, and the rotating speed of driving engine and the horsepower output of electrical generator are comprise that by detecting simultaneously energy-storage capacitor voltage, dynamo current, the speed of a motor vehicle and chaufeur control the command value of throttle by electricity generating controller; The accurate s operation control of computer is more far better than manual control throttle effect, and this mainly is to maintain low oil consumption and Low Emission Zone by the working curve of controlling driving engine as far as possible, thereby reaches the environment protecting of energy-saving and emission-reduction.
