Description
Technical field
The utility model is related to electric vehicle engineering fields, are specially a kind of electric automobile motor test system.
Background technology
With the rise of new energy industry, electric vehicle engineering is growing, and the application of electric vehicle is also more and more extensive.
In the actual travel of electric vehicle, it may appear that similar moment throw load operating mode, motor control at this time are different from normal row
It sails.And current Motor Measuring System fails to provide this analoglike operating mode, actual calibration is often ignored or directly exists
It is completed on real vehicle, there is some potential safety problems.
The content of the invention：
The purpose of this utility model is to provide a kind of electric automobile motor test system, the security that can demarcate vehicle
Higher, to overcome the problems, such as present in background technology.
To achieve these goals, the technical solution of the utility model is：
A kind of electric automobile motor test system, it is characterised in that：Including test loop and manipulation circuit, test loop connects
DC power supply and load motor controller are connect, manipulation circuit is equipped with the manipulation of switches part of series connection and testing of electric motors controller；
Load-relay is further included, the relay switch part of load-relay is arranged on test loop, load-relay
Relay coil be arranged on manipulation circuit on；Load motor controller for connecting load motor, use by testing of electric motors controller
In connection motor in electric automobile to be measured.
It is preferred that relay switch part one end connection DC power supply cathode output end, relay switch part it is another
The electrode input end of end connection load motor controller；The cathode output end of DC power supply and the cathode of load motor controller are defeated
Enter end connection.
It is preferred that further include console.
It is preferred that manipulation of switches part and testing of electric motors controller are arranged on console.
It is preferred that load-relay is arranged on console.
The beneficial effects of the utility model are：During Work condition analogue, by console manipulation of switches part disconnect, load after
Electric appliance because relay coil power down cause relay switch part disconnect, load motor controller dead electricity, load motor stalling, then by
The motor in electric automobile of survey loses load.The utility model is simple in structure, characteristics of compact layout, easy to operate, and system is easy to recover, can
With the moment throw load operating mode of realistic simulation vehicle reality, there is more comprehensive meaning for vehicle calibration.
Description of the drawings
Fig. 1 is the structure diagram of the utility model embodiment.
In figure：1- DC power supplies, 2- load motor controllers, 3- load-relays, 3.1- relay switch parts, 3.2- after
Electric apparatus coil, 4- consoles, 5- manipulation of switches parts, 6- testing of electric motors controllers.
Specific embodiment
The utility model is described further with reference to the accompanying drawings and examples.
A kind of electric automobile motor test system, it is characterised in that：Including test loop and manipulation circuit, test loop connects
DC power supply 1 and load motor controller 2 are connect, manipulation circuit is equipped with the manipulation of switches part 5 of series connection and testing of electric motors controller 6；
Further include load-relay 3, the relay switch part 3.1 of load-relay 3 is arranged on test loop, load after
The relay coil 3.2 of electric appliance 3 is arranged on manipulation circuit；Load motor controller 2 is used to connect load motor, testing of electric motors
Controller 6 is used to connect motor in electric automobile to be measured.
Relay switch part 3.1 one end connection DC power supply 1 cathode output end, relay switch part 3.1 it is another
The electrode input end of end connection load motor controller 2；The cathode output end of DC power supply 1 is negative with load motor controller 2
Pole input terminal connection.
Console 4 is further included, manipulation of switches part 5 and testing of electric motors controller 6 are arranged on console 4, load-relay 3
It can also be arranged on console 4, load-relay 3 can also be arranged on outside console 4.
During Work condition analogue, the manipulation of switches part 5 in console 4 is disconnected, load-relay 3 falls because of relay coil 3.2
So that relay switch part 3.1 disconnects, 2 dead electricity of load motor controller, load motor stalls electricity, then tested electric vehicle
Motor loses load.The utility model is simple in structure, characteristics of compact layout, easy to operate, and system is easy to recover, can be whole with realistic simulation
The moment throw load operating mode of vehicle reality has more comprehensive meaning for vehicle calibration.
It should be appreciated that for those of ordinary skills, can be improved or converted according to the above description,
And all these modifications and variations should all belong to the protection domain of the appended claims for the utility model.Do not make in this specification in detail
What is carefully described partly belongs to the prior art well known to professional and technical personnel in the field.
