Used for electric vehicle symmetrical distribution power supply and motor driven systems
Technical field
The present invention relates to a kind of power supply and motor driven systems of improved series hybrid used for electric vehicle, specifically the symmetrical distribution power supply and the motor driven systems of series hybrid used for electric vehicle.
Background technology
The power supply and the motor driven systems of the normal use of series hybrid electronlmobil at present, as shown in Figure 1.This drive system is connect successively by A-battery 1, starter motor 2, internal combustion engine 3 and electrical generator 4 and constitutes.Making internal combustion engine 3 rotate the mechanical energy that produces by fuel combustion goes to drive electrical generator 4 generatings, is about to mechanical energy and converts the driving electric source to.A-battery 1 provide in the automobile such as Lighting System and other system's electricity consumption (not shown), and be used for, thereby open internal combustion engine work to starter motor 2 power supply.Electrical generator 4 connects with electrokinetic cell 11 forming circuits through power rectifier 10, and the three plase alternating current that electrical generator 4 is produced is rectified into direct supply, and it is used for providing the driving electric source to drive motor 13 on the one hand; One in the face of electrokinetic cell 11 chargings.The nominal voltage that electrokinetic cell provides is usually about 300V, it also plays a part to stablize the rectifier output dc voltage, therefore, it participates on the one hand to drive motor 13 feed drive electric power source, the on the one hand then charging of the direct supply after 10 rectifications of received power rectifier, its level is generally 250V～400V.Drive motor 13 is connected its output shaft coupling automotive proplsion 5 (not shown)s by driving inverter 12 with electrokinetic cell 11.Drive motor 13 can be converted into the mechanical energy that drives running car to the electric energy of electrical generator and electrokinetic cell generation under the control that drives inverter 12 and controller (not drawing among the figure) thereof, also can be converted into power storage to the recover kinetic energy that discharges in the Motor Vehicle Braking Procedure among electrokinetic cell, make this drive system have energy-saving advantages.Electrokinetic cell 11 also 18 charges store electrical energy through the DC unit to A-battery in addition, needs with the electricity consumption that guarantees various facilities in the automobile mesolow circuit.
The maximum power of system shown in Figure 1 mainly is subjected to high voltage power cell pressure and the restriction that drives power semiconductor switch current capacity in the inverter.For breaking through the restriction of power semiconductor switch current capacity, obtain bigger horsepower output, common way is device for power switching use in parallel, shortcoming is that the problem of current balance type in the circuit parallel is difficult for solving.For guaranteeing reliability, the current capacity operation is often fallen after the device for power switching parallel connection, cause the waste of device for power switching current capacity.Device for power switching another shortcoming of using in parallel is that drive motor, the physical dimension that drives electric current busbar, power cable in the inverter increase, and makes the corresponding increase of difficulty of arranging in manufacturing, encapsulation, the car.
The method of the total power-handling capability of another kind of raising electronlmobil as shown in Figure 2.Promptly set up the driving inverter 15, the drive motor 16 that connect by successively, be electrically connected electrokinetic cell 11, total driving power is doubled by driving inverter 15.But the same change speed gear box of the output shaft mechanical connection of drive motor 13,16 realizes that machinery is in parallel, also can drive the forward and backward Transmission Bridge of electronlmobil respectively by transmission system, or the wheel of direct drive electronlmobil.The advantage of this system is to have increased system redundancy, and the drive system global reliability is improved; The little flexible arrangement that makes in automobile of each component physical size in the system, and can adapt to multiple automobile dynamic system structure, yet, remove to drive more high-performance electronlmobil if will further improve total driving power, then almost suffer from almost the insoluble problem that is suffered from system shown in Figure 1.
Summary of the invention
In sum, how keeping the advantage of prior art and overcome the limitation that improves driving power, is technical matters to be solved by this invention, therefore, the object of the present invention is to provide a kind of used for electric vehicle symmetry independent power source and motor driven systems.
