Description
Technical field
The present invention relates to elec. vehicle (Electric Vehicles, EVs) field, and can be used for being equipped with power autonomous EVs and with external power supply bonded assembly EVs (tramway train, trackless trolley car, inter-city train).
More specifically, the present invention relates to the technology decision-making of electric energy recovery (storage) aspect in the transport vehicle braking procedure.
Background technology
Known in the state of the art have various strategies that the electric vehicle braking process reclaims the service efficiency of electric energy that are used for improving.
For example, known " Battery-fed vehicle traction motor with capacitor boost " (patent FR2757806A1, B60L11/00, open July 3 1998 date).This device comprises a motor, and this motor links to each other with the wheel with electronically controlled elec. vehicle, and this electron steering is by storage battery, cond group and logical block power supply.The output of logical block links to each other with relay coil, connects the cond group in the contact of this relay coil with storage battery.Basically, during regenerative brake and in the transport vehicle accelerator, the cond group is coupled together.If regenerative brake does not make the cond group be full of electricity, then use the charger that independently relies on battery.
The shortcoming of prior-art devices comprises, when storage battery was connected with the cond group, the power size that causes power subsystem unit owing to the overvoltage power supply was than high and owing to having used the balancing cell charhing unit to cause the complexity of device too high.
In addition, during regenerative brake, only by the state of said cond group and battery and by the braking ratio decision, cond group charge rate can exceed permission (recommendation) value that possibly cause battery age to shorten to the cond group charge rate that equates with the battery charge rate.
A kind of " electric drive motor that is used for wheel " that be disclosed among the Soviet Union inventors certificate No.74107 is close with technical spirit of the present invention.This one type of prior art syringe comprises the power supply that is designed for to battery charge, and this battery links to each other with the molecule capacitor unit through isolation diode, and this molecule capacitor unit is parallelly connected with controlled voltage type current converter.The speed of rotation is by the variation of the output voltage of above-mentioned current converter control, this current converter be used for the certain voltage conversion decompression than during electric drive motor transmits electric power and is braking with the certain voltage conversion step-up than carrying out power recovery from electric drive motor.In braking procedure, stop the energy transport from the battery to the motor, said motor converts generator mode into.In this case, act on the wheel with the proportional brake torque of the electric current that produces in the electrical generator output procedure, current converter is in the pattern of electrical generator overvoltage work.In further operational process, electric power is transferred to current converter from the cond group, and in this case, this process will last till that the voltage of battery and cond group equates.Afterwards, motor is battery-powered.
The shortcoming of this one type of prior art syringe comprises: used isolation diode between main power source and the main user; Wherein, main power source promptly is meant storage battery, and main user is meant current converter in electric drive motor; When electric drive motor is under the electric machine operation state, this isolation diode can cause excess loss; Also used radiating gill in the isolation diode, this radiating gill is installed on the power circuit, makes the weight and the saving in space deterioration parameter of elec. vehicle.In the braking procedure, as long as power storage is in the cond group, will be on the current converter terminal accumulated voltage.This situation causes when the capacitor drive device of the power amplifier of selecting current converter such as power transistor, power filter etc.; Further requirement must be arranged; These require to cause usually the raising with the current converter cost of over-evaluating of power size ratio; And because current converter should work under the power line voltage that has than big variation range, these requirements can cause the logic (tuning) of current converter operation complicated.
The shortcoming of the scheme of prior art also comprises the use that is stored in energy in the cond group, and for example, when car speed begins when 0 (minimum value) becomes new (presetting) value, the discharge of cond group starts from the startup of vehicle.In this course, electric power that transducer consumes and the supply current that thereupon produces become and the corresponding maxim of vehicle maximum speed from 0 (minimum value).Therefore, desirable method is used to accelerate to middle speed value and higher velocity amplitude for the electric power that will be stored in the cond group, thereby reduces power source loads and reduce the maximum received current of power supply.
The article (www.powerinfo.ru/accumulatortype.php) that is entitled as " Sealed Lead-Acid Batteries " proposes the relation of lead-acid battery service life and depth of discharge.Shown in curve, the double reduction of depth of discharge can increase cycle life, for example battery service life.Similar relation also is applicable to the battery of other type.
When independently the wheel hub electric drive motor is used on axletree or the every axletree of an EV with 2, can produce the reasonable control problem on the independent electric drive motor.
Among the RU2048309C1 disclosed a kind of " battery-driven car " " approach technical spirit of the present invention.One type of prior art syringe comprises AC-battery power source; Be used to select the switchgear " front and back " of moving direction, mode of operation comprises: back-wheel drive, f-w-d, four wheel drive; Respectively with the driving and the brake pedal of variable rheostat coupling; And the reversible electric drive motor of front and back wheel.
For same velocity amplitude is provided, the electric drive motor of front and back wheel is series coupled in couples.
The shortcoming of one type of prior art syringe comprises can not carry out shunt control to the moment of torsion of the wheel of velocity amplitude and/or axletree.
During EV turned, the speed of whole 4 wheels was normally different, and turn radius is more little, and velocity contrast is big more.And the total current of axletree motor causes identical wheel torque on axletree.Simultaneously, in general, the resistance wheel torque on the axletree is different, and Motor torque or brake torque required on the axletree also should be different.For example; When a wheel contacts with mud; Other wheel contacts with pitch, and then the traction coefficient on the different wheel has the difference of n rank degree, and first wheel in the scheme of prior art will rotate with maximum speed; And meanwhile second wheel remains static, and is identical with the situation with mechanical differential.In the turning process, when the wheel of EV is set to same speed, during but with different actual speed operation, will cause the different loads of motor.Simultaneously, the selection of speed preset value is extremely important.If actual wheel speed is greater than preset value, drive motor converts braking (electrical generator) pattern into, and wheel begins to brake EV.Can cause the EV loses stability like this.

The specific embodiment
For making the object of the invention, technical scheme and advantage clearer, will combine accompanying drawing that embodiment of the present invention is done to describe in detail further below.
Fig. 1 illustrates the illustrative circuitry of EV of the present invention, and it comprises provides (vehicle-mounted) reversible power supply for oneself or be coupled in outside reversible power supply through terminal 1 and 2, and the voltage on the terminal 1 and 2 is measured through voltage sensor, and electric current passes through current sensor measurement.
This circuit diagram has also been represented ultracapacitor (SC), and its voltage is measured through sensor 2Sv.SC links to each other with 2 with the lead-out terminal 4 of reversible converter (RC), and the lead-out terminal 3 of reversible converter links to each other with 2 with the terminal 1 of power supply 1 with 2.
Fig. 2 has explained an embodiment of reversible converter (RC), and reversible converter constitutes its basis by parallelly connected with 4 bypass diode D1-D4 4 transistor switch S1-S4 and inductive choke coil L, and the electric current of this induction coil L is measured through sensor 2Sc.
Comprise the output of the sensor of the output of the speed sensor that links to each other with a motor, (Control System CS) links to each other with control system.
CS output links to each other with the control input of RC and DK.
Shown in Figure 3 is the top layer control system of EV; This top layer control system is used for the signal of steering angle sensor, the position of acceleration pedal (setting the speed and/or the moment of torsion of motor), and brake pedal (setting brake torque), hand (Parking) position of stopping, from the Pattern Select Switch of RC1 to RCi (forward direction-back to etc.) each other not alternately.
Device work of the present invention is following.
As the response of operator's (chaufeur) being rotated ignition lock, CS carries out the charging from 1 couple of SC of power supply through RC.At first, transistor K1 relative pulse time length (connecting time) is become 1 from 0, make power supply 1 charge to SC.Then, through startup and the operation of transistor K1, SC charges to maximum voltage (Uscmax).
Start in the EV process, control system is controlled the electric current of reversible power supply 1 through current sensor 1Sc, and in EV starting (its moment of torsion is confirmed through the signal from speed sensor) process, control system is specified the levels of current with the static constantly corresponding power supply 1 of EV.From this (starting) beginning constantly, CS begins SC is discharged in the reversible converter (EC1-ECi), thereby the electric current of power supply 1 is maintained fixing horizontal.Therefore, realize the restriction of power supply 1 starting current.
Brake and in the output of current sensor 1Sc, reclaim in the process of electric power at EV, output signal polarity changes.When said signal exceeded nominal (allowing) the charge rate corresponding preset value with reversible power supply (SB), CS began the charging to SC, and the charging current with power supply 1 maintains preset level simultaneously.
Magnitude of voltage among the SC is measured through voltage sensor 2Sv.The SC capacitance is selected according to the absorption of EV kinetic energy storage, and with maximum speed and EV maximum gross, for example maxim is corresponding.During the maximum voltage in reaching SC (Uscmax), CS terminates as the SC charging.If at this time the power recovery process does not stop (for example braking procedure is not accomplished), for example apart from descending, then voltage begins accumulation gradually on terminal 1 and 2 to EV long.Signal to from 2Sv responds, and CS sends control signal to discharge key (DK).In this case, CS progressively changes the DK electric current through ballast resistor R, and this ballast resistor R is used for power supply (terminal 1 and 2) shunting, and progressively is limited in the voltage on terminal 1 and 2.
If the voltage levvl after the end of braking on the SC terminal is not enough, then CS charges from 1 couple of SC of power supply through RC once more.
Thus, EV of the present invention provides precharge, and in needs, in the parking area SC is charged to the required voltage level once more, and at the EV period of acceleration, SC is discharged in the load.In this case, supply current is limited in EV quiescent current (moment of torsion) level.Because reversible converter, SC (when needing) is discharged to the maxim Uscmax of the voltage that is lower than power supply 1.During moving with middle speed (less than the EV maximum speed), the SC storage enough is used for the energy of reserve of the starting current of power supply, when needing, can accelerate to maximum speed, and SC can also receive the electric energy that (storage) reclaims from middle speed brake to stopping period.
The part of recuperated energy is uploaded to reversible power supply according to the requirement of power source charges condition.
Device of the present invention reduces the adjustment loss through increasing the recuperated energy degree of utilization; Improve the life-span (the very major part of the cost structure EV total cost of this power supply) of providing reversible power supply for oneself; And, because the expansion of the change of voltage scope on the SC terminal and the part of recuperated energy is fed back to reversible power supply according to the power source charges condition; Reduce weight and the cost parameter of SC, saved the space.
Device of the present invention can be used for having power autonomous elec. vehicle and has the municipal electric power transportation means (tramway train, trackless trolley car, inter-city train) of outside (coupling) power supply.Among the latter, invertibility can realize through go up installation cond group in EV input ( terminal 1 and 2).Activation motor can be an any kind, DC or AC.
Current converter is the operation that electric drive motor provides all 4 quadrants of electromechanical properties, and has invertibility, for example during braking, carries out energy recovery.
In Fig. 3 illustrated example; EV comprises or is connected in power supply (PS) 1; Energy recycle device (2), moving velocity (moment of torsion) are set control (acceleration pedal (3)), brake torque and are set control (brake pedal (4)), Move Mode select switch (forward direction, back to, stop (5)).This device comprises with vehicle coupling or is arranged on the reversible converter RC1-RCi of the motor (6) on wheel (motor-wheel) MW1-MWi (7); Steering angle sensor (8) and top layer control system (TLCS) (9); Wherein, Said setting links to each other with the TLCS input with model selection control, steering angle sensor, and TLCS output links to each other with the control input of current converter RC1-RC4.
Power supply (PS) can be storage battery (SB) and/or the electrochemical generator that uses fuel cell.Also can use " combustion engine-electrical generator " system, it combines with SB, form so-called combined power plant (Combined Power Plant, CPP).PS can be external, as in the trackless trolley car.
The energy recycle device of more than describing, comprising energy storing device, ultracapacitor for example; Be received in the energy that produces by motor during the braking (recovery); The energy storage, and, during EV quickens and moves, feed back to power circuit as response to the TLCS instruction.
Current converter RC1-RC4 provides the setting according to TLCS, speed and/or the moment of torsion of controlling and driving motor D M1-DM4.This current converter has invertibility, for example, in the working process of braking under (electrical generator) condition, current converter with energy back to power circuit.
Activation motor AM1-AM4 can be all kinds, for example DC or AC, commutator or brushless servo.Especially, they can be for being arranged on the reverse sync three phase electric machine with permanent-magnet-field (its rotor is the outer buttons rotation member, and stator is inner stationary parts) on the wheel (motor-wheel).
Fig. 4 representes to be used for the TLCS output signal of setting speed and electric current (moment of torsion) I (M) and the relation between the accelerator pedal position Faccel.Stop at EV, when acceleration pedal is positioned at reference position, TLCS sets the minimum velocity value
MinWith 0 current value (moment of torsion).When acceleration pedal was stepped on down, operator's (chaufeur) set the moment of torsion that is produced by AM.Along with electric current (setting) moment of torsion reaches the numerical value of resisting static torque, EV starts to walk and quickens with a dynamic torque, and this dynamic torque is by moment of torsion of setting and the definition of the difference between the static torque, and for example, the moment of torsion of this setting is determined by the operator.As long as EV reaches at it
MinQuicken after the horizontal current velocity amplitude, then the operation electricity drives (ED) to keep the preset value of speed in system, and the torque limited among the ED is at M
LimitLevel.Thus, EV is with the speed starting (starting) by the chaufeur decision.
Along with the reduction (or acceleration pedal is released fully) of pre-set velocity value, ED changes the braking mode (sliding) of (or 0) brake torque that has minimum over to.The state of minimum brake torque or numerical value are set according to the facility (custom) of chaufeur in advance in this pattern, and is for example, identical with " vehicular electric machine braking ".
In order to increase brake torque, chaufeur is stepped on down brake pedal, sets the required numerical value of braking and the desired rate of braking is provided.Based on the information of AM velocity correlation, TLCS follows the trail of the dynamic change of braking procedure, and when needing, thereby the numerical value of its restriction brake torque provides the anti-lock pattern.
Same technology is used to control acceleration/accel.Thereby TLCS provides the numerical value of anti-skidding pattern restriction Motor torque.
Through the horizontal acceleration sensing device of installing, if having required software, TLCS can also provide road to keep system (Road-holding System).But compare with the said operational mode of execution in the transport vehicle of prior art; In EV of the present invention, said pattern only provides through Eltec, for example; The motor through limiting each wheel respectively and/or the numerical value of brake torque; It significantly increases control efficiency under the situation that the energy recovery condition is provided, and the continuation of the journey mileage of the EV that once charges.
