Driver test system

Abstract

An embodiment of the invention discloses a driver test system, which comprises a test platform, an adjustable power supply unit and a feedback load unit. The test platform comprises an upper computerand a test unit. The test unit, the adjustable power supply unit and he feedback load unit are controlled by the upper computer; the direct voltage output by the adjustable power supply unit is adjustable to meet requirements of different types of drivers; the feedback load unit can simulate various types of loads to meet requirements of different test items; and the test unit can obtain data of the different test items. The test system can be compatible with measurement of a plurality of test items of different types of drivers. The test system is good in compatibility, high in university, low in cost and high in test efficiency. The test system does not use a slip motor, thereby greatly reducing power consumption and improving habitability of a workshop.

Description

technical field [0001] The invention relates to the technical field of testing equipment, in particular to a testing system for a driver. Background technique [0002] As a key component of an electric vehicle, the driver's safety and reliability directly affect the performance of the vehicle, which is life-threatening. Therefore, the driver of an electric vehicle must undergo a load test and an aging test to check product quality before leaving the factory. [0003] At present, for the on-load test and aging test of electric vehicle drives before leaving the factory, the general method in the industry is to use an energy-consuming slip motor with simple control and reliable performance as the load. Due to the large number of power, volume and models of electric vehicle drivers, in order to meet the test requirements of multiple models, it is necessary to design a variety of different test platforms in different power segments. The above electric vehicle driver on-load test...

AI Technical Summary

Problems solved by technology

[0004] 1. There are many types of motors and high prices: Since the load power of the motors is constant and cannot be adjusted, various types of motors are required to meet the full range of product tests, resulting in increased production costs

[0005] 2. High energy consumption and poor economy: When the motor is under load, it converts a large amount of electric energy into heat, which increases production costs and wastes resources. At the same time, it leads to an increase in the ambient temperature of the workshop and an increase in the cost of air conditioning.

[0006] 3. Poor flexibility: the motor is large in size and heavy in weight, so it is difficult to design it as a mobile device for on-site testing and use

[0007] 4. Loud noise: When the motor is running, it will generate a lot of noise and vibration, which will reduce the livability of the workshop and affect the production efficiency

[0008] 5. The number of platforms is large: the test uniformity is poor, and multiple test platforms need to be built, resulting in waste of cost resources and site resources
