Platform.Electric automobile is driven by motor, and the drive system that motor and electric machine controller collectively form electric automobile (is also referred to as moved
Force system).There is high voltage, the high current signal of alternation with can not being avoided in system during motor operation, surrounding environment can be made
Into serious electromagnetic disturbance, the major hidden danger of influence each electronic system normal work of electric car is possibly realized.Existing standard is only right
The vehicle radiation disturbance performance of electric car is constrained, but it is disturbing for parts that vehicle, which harasses one of deciding factor of performance,
Immunity energy, and one of most important harassing and wrecking source of electric car is exactly its drive system.It can not be solved in subsystem or parts one-level
The electromagnetic compatibility problem of drive system, is difficult to be lifted the Electro Magnetic Compatibility of vehicle.Therefore, International Standards Organization has started to beg for
By the electromagnetic compatibility test standard of correlation subsystem.
Conventional test experience have shown that, the Electro Magnetic Compatibility of drive system of electric motor vehicle has in the operation of unloaded and bringing onto load
Bigger difference, idle condition can not really reflect the Electro Magnetic Compatibility of drive system.Thus industry is in the urgent need to electric car
Drive system Electro Magnetic Compatibility band carries the test system scheme of test.When drive system of electric motor vehicle band carries test, generally select
Electrical dynamometer is loaded, and electrical dynamometer can also produce stronger harassing and wrecking in itself, thus obtain the standard of tested drive system
True electromagnetic compatibility test result, it is necessary to by electrical dynamometer and tested drive system (including tested motor and electric machine controller) every
Leave and.
As shown in figure 1, existing testing scheme is required to put mechanism for testing (including tested motor 2 and electric machine controller 3)
The special anechoic chamber, 1 built in huge fund, testing cost is high, and electrical dynamometer is placed on outside anechoic chamber, 1, electronic to avoid
When dynamometer machine works, the electromagnetic disturbance influence test result of generation.In addition to electrical source of power 4 and wallboard connector in addition,
5.So it is accomplished by carrying out processing through walls to anechoic chamber, 1, not only processing cost is high (up to several ten million RMB), and right
The overall performance of anechoic chamber, 1 also has an impact.
In addition to the scheme that electrical dynamometer is external, also there are feelings electrical dynamometer being placed in anechoic chamber,
Condition, but the way that the electromagnetic disturbance of load influences on test result is reduced by the shielding measure on electrical dynamometer, equally deposit
The problem of high cost, and shielding measure is slightly improper, it is possible to cause test result abnormal.
Utility model content
The utility model aim to provide it is a kind of substitute method of testing, by the use of do not produce the hydraulic dynamometer of electromagnetic disturbance as
The load of drive system, solves load when drive system of electric automobile band carries test and produces electromagnetic disturbance in itself or load external
Anechoic chamber, is caused to need to carry out the problem of high cost is transformed.
Therefore, the technical scheme that is used of the utility model for：A kind of Electro Magnetic Compatibility of drive system of electric automobile
Band carries test system, including anechoic chamber, and the tested motor and electric machine controller being placed in anechoic chamber, is arranged at electric wave
Electrical source of power outside darkroom, the electrical source of power, tested motor are connected with electric machine controller by wire, in leading for anechoic chamber,
Line is additionally provided with hydraulic dynamometer, outside anechoic chamber, by being provided with wallboard connector at position in the anechoic chamber,
Be additionally provided with cold water storage cistern, boiler, hydraulic dynamometer controller and water pump, the hydraulic dynamometer and tested motor be connected to by
Measured motor is loaded, and the cold water storage cistern, boiler are connected by each self-corresponding water pipe with hydraulic dynamometer respectively, and every water pipe exists
Part outside anechoic chamber, is turned on the part in anechoic chamber, by ripples conduit, and two water pipes are located at the portion outside anechoic chamber,
Point be respectively arranged with water valve, the water pump is arranged on water pipe corresponding with cold water storage cistern, and water valve, water pump respectively with hydraulic dynamometer control
Device electrical connection processed.
As the preferred of such scheme, the tested motor is located on same testboard bay with hydraulic dynamometer, the electricity
Machine controller is located on test desk, facilitates mounting arrangements.
In addition, the electric machine controller is equipped with linear impedance stabilization network, linear impedance stabilization network and motor control
Device shares a test desk.
The beneficial effects of the utility model：The hydraulic dynamometer of electromagnetic disturbance transmitting directly be could be used without as tested motor
Load, be tested motor loading, while cold water storage cistern, boiler, hydraulic dynamometer controller, water pump, water valve are arranged at
Outside anechoic chamber, the water pipe being located at outside anechoic chamber, that cold water storage cistern, boiler are connected with hydraulic dynamometer is selected into ripples conduit,
So as to avoid the electromagnetism outside anechoic chamber, from entering by water pipe in anechoic chamber,.The harassing and wrecking shadow caused by load is thus not present
The problem of ringing test result, ingenious in design, novel, cost is low, test result is accurate.And traditional pass through electrical dynamometer
It is placed in anechoic chamber, is the mode of tested motor loading, because electrical dynamometer is strong harassing and wrecking source, it is necessary to tightly be shielded
Cover, and tightly shield that difficulty is larger, required cost is also higher, is extremely difficult to allow the harassing and wrecking of tested motor not influence test result
Purpose.
