Description
Technical field
The present invention relates to a kind of dual power supply new-energy automobile actuating device.
Background technology
Raising along with people's environmental consciousness, the tradition fuel-engined vehicle is replaced by energy-conservation and new-energy automobile gradually, energy-conservation and new-energy automobile refers generally to hybrid vehicle and pure electric automobile, no matter be which kind of automobile, all comprise power supply and drive motor in its basic driver structure, power to drive motor by a control setup with power supply, and then provide all or part of propulsive effort to vehicle.Generally all use single power supply in conventional hybrid power vehicle and the pure electric automobile, i.e. electrokinetic cell or super capacitor, the two is suitable for being used in the different systems because of merits and faults separately.Super capacitor has larger electric charge loading and unloading capacity, service life cycle is long, large current discharging capability is superpower, energy conversion efficiency is high, the process loss is little, be applicable to cooperate with driving engine in the hybrid electric drive system, but the ultracapacitor storing electricity is less, can not keeps more for a long time the pure motor driving of vehicle; And electrokinetic cell has high-energy-density and high horsepower output, can recycle under the high magnification partial state of charge, working temperature range is wide, can reach 10 years service life, safe and reliable, the general driving that is used for pure electric automobile, but its service life cycle is short, discharge and recharge slowlyer, and power demand is larger at electric motor starting and when accelerating, and needs power supply that a sharp-pointed discharge process is arranged, along with the horsepower output of motor smooth running battery held stationary progressively, have a greatly reduced quality because the characteristic of battery itself, battery are transmitted its life-span of high power pulse repeatedly, this discharge mode can badly influence the life-span of battery.
Summary of the invention
The invention provides a kind of new-energy automobile actuating device, two kinds of power supplys are combined effectively, can be applied to take full advantage of the advantage of two kinds of power supplys in hybrid power and the pure electronic two kinds of systems, power supply complete, that continue is provided in protection power source.Technical scheme provided by the invention is:

Wherein 1 is the first power supply, the 2nd, and second source, the 3rd, control setup, the 4th, duplex winding electrical motor, the 5th, driving engine.
The specific embodiment
A kind of actuating device comprises electrical motor and power supply, and described power supply is connected with described electrical motor by a control setup, it is characterized in that, described power supply is divided into the first power supply 1 and second source 2, and described electrical motor is duplex winding electrical motor 4.
As an embodiment of apparatus of the present invention, described the first power supply 1 is super capacitor, and described second source 2 is electrokinetic cells.On the present embodiment basis, can also comprise a driving engine 5, described driving engine 5 and described duplex winding electrical motor 4 mechanical connections.
Below for convenience of description, with duplex winding electrical motor 4 referred to as electrical motor or motor.
Apparatus of the present invention provide the following power supply way of output: described super capacitor and described electrokinetic cell are exported simultaneously; Perhaps described super capacitor and described electrokinetic cell are exported separately; Perhaps described super capacitor and described electrokinetic cell reclaim simultaneously; Perhaps described super capacitor and described electrokinetic cell reclaim separately.Further, when described motor start-up or acceleration, described super capacitor is exported separately; Perhaps described motor start-up or when accelerating, described super capacitor and described electrokinetic cell are exported simultaneously.
In addition, the present invention also provides the control method of actuating device, may further comprise the steps:
A. determine electric motor state.
B. select the power supply way of output.
C. calculate the battery fan-out capability.
D. determine the export ratio of battery and super capacitor.
The function of above-described actuating device need to realize that the below is take the mode of operation of pure motoring condition as example labor actuating device of the present invention by rational mode.Double-winding motor is to be made of two group of three phase winding, and its principle of work and common three-phase winding motor are as good as, so repeat no more its principle of work here.At first need to determine the state of electrical motor: starting state, acceleration mode, steady slew mode and deceleration regime.Determine that by the state of electrical motor system obtains the mode of electric weight from power supply.
Start or acceleration mode if electrical motor is in, select the mode of the common output of battery and super capacitor.Calculate the fan-out capability of battery by the battery data of battery management system transmission.Wish (such as the degree of depth of acceleration pedal) in conjunction with chaufeur, control super capacitor and electrokinetic cell are exported jointly, the characteristics of combining super capacitor and battery self, but the little instantaneous output of super capacitor capacity is large, the electrokinetic cell capacity is large still can't to provide larger horsepower output the short time, so provide larger horsepower output by super capacitor when jointly exporting, electrokinetic cell provides less horsepower output; If this moment, the super capacitor electric weight was sufficient, super capacitor is exported separately, provide required high-power in motor start-up or the accelerator, certainly, super capacitor and electrokinetic cell are exported jointly, but consider that electrokinetic cell circulation discharge life is less, in the situation of super capacitor electric weight abundance, all use super capacitor to carry out the larger driving work of horsepower output as far as possible.
If electrical motor is in the smooth rotation state, namely horsepower output is constant, and can use electrokinetic cell to provide power for it this moment, continues to power to electrical motor.
If electrical motor is in deceleration regime, be car retardation, for reducing degradation of energy, pure electric automobile and hybrid vehicle have generally designed energy brake and have reclaimed function, namely because the electrical motor that brake drives reverses, mechanical energy is converted into electric energy and is recycled to electrokinetic cell or super capacitor.
