Abstract
The utility model discloses a device for rapidly testing a power module and a drive unit of an electric vehicle. The device is composed of a computer, a drive signal controller, a drive signal collector and a power supply/ load module. The drive signal controller is connected with the computer; the drive signal controller is connected with the drive signal collector; and the power supply/ load module is connected with the computer and the drive signal collector and provides power to the computer and the drive signal collector. According to the device for rapidly testing the power module and the drive unit of the electric vehicle, whether the power module and the drive unit of the electric vehicle are deficient in function and performance or whether the problems, such as poor welding, wrong weldments, device damage and the like which influence driving quality, exist or not are evaluated by collecting, analyzing driving work information under the condition that test condition is set.
Description
Technical field
The utility model relates to a kind of power model and driver element device for quick testing of electric motor car.
Background technology
At present, electric automobile is in global fast development, and inverter is as its core drive assembly, and its performance directly affects dynamic property, economy and the comfortableness of car load.Power model and its driver element are the inverter critical components, and whether its quality not influence of light electric energy conversion normally carries out, and also affects car load and high-voltage safety danger whether occurs.
Based on above reason, it is just particularly important whether power model and driver element detect normally, traditional test has two shortcomings, the one, only for driver element, carry out the signal level detection, this detection lacks the test of power model and driver element integral body, can't guarantee the normal of both integrated rear signal level operations; The one, carry out the signal level detection for power model and driver element, this detection lacks the power level test, can't guarantee to be integrated in inverter system power level operating normal.
Summary of the invention
The purpose of this utility model is to solve the power model of electric motor car and the problems referred to above that drive the signal traditional detection to exist, and a kind of power model and driver element device for quick testing of electric motor car are provided.
The utility model is comprised of computing machine, driving signal controller, driving signal picker and power supply/load blocks; The driving signal controller is connected with computing machine, drives signal controller to be connected with driving signal picker, and power supply/load blocks is connected with the driving signal picker with computing machine respectively, to computing machine and the power supply of driving signal picker; Computing machine shows for testing operating mode editor and input and test data and duty; Driving signal controller is the instruction of accepting computing machine, and the device that drives working signal and accept the driving condition feedback signal is provided; Drive signal picker will reliably connect power model and the driver element sampled point of electric motor car and the output of power model driver and input signal are drawn to driving signal controller; Power supply/load blocks provides high voltage supply and the load in test.
Computing machine is for driving operating condition design and operational data to gather display terminal; Drive signal controller for accepting the host computer instruction, provide and drive working signal and accept the driving condition feedback signal device; Drive signal picker for guaranteeing and the device that drives the test point good contact, power supply/load blocks is for providing the device of power power-supply and power termination in test.
The beneficial effects of the utility model:
Assess the power model of electric motor car and the not enough or no failure welding that exists whether driver element exists function and aspect of performance by gathering, analyze the driving job information of setting under the test operating mode, wrong weldment, the impact such as device failure drives the problem of quality.
The accompanying drawing explanation
Fig. 1 is structured flowchart of the present utility model.
Embodiment
Refer to shown in Fig. 1, the utility model is comprised of computing machine 1, driving signal controller 2, driving signal picker 3 and power supply/load blocks 4; Driving signal controller 2 is connected with computing machine 1, drives signal controller 2 to be connected with driving signal picker 3, and power supply/load blocks 4 is connected with driving signal picker 3 with computing machine 1 respectively, to computing machine 1 and 3 power supplies of driving signal picker; Computing machine 1 shows for testing operating mode editor and input and test data and duty; Driving signal controller 2 is instructions of accepting computing machine 1, and the device that drives working signal and accept the driving condition feedback signal is provided; Drive signal picker 3 will reliably connect power model driver element and the power model sampled point of electric motor car and the output of power model driving and input signal are drawn to driving signal controller 2; Power supply/load blocks 4 provides high voltage supply and the load in test.
The utility model principle of work is as follows:
Workflow is as follows:
1, computing machine 1 starts the power model driven in signal picker 3 and drives device for quick testing after setting test operating mode, operating voltage and load, drives signal controller 2 and power supply/load blocks 4 to form starter gear;
2, drive signal controller 2 that computing machine 1 operating mode instruction is converted into and drives signal to export to driving signal picker 3, drive signal picker 3 will drive signal to input to power model and drive the work of power ratio control module, by driving signal picker 3 to drive the temperature of power module, the fault-signal that gather to feed back to power model, drive signal controller 2 to be processed simultaneously;
3, after driving signal picker 3 by the Information Monitoring Treatment Analysis, by test sample, be that the power model driver element of electric motor car and state and the result feedback of power model allow the tester understand the test sample situation to computing machine 1.
