Electric vehicle controller automatic test system

Abstract

The invention discloses an electric vehicle controller automatic test system, which relates to the technical field of electric vehicle tests. An auxiliary direct current regulated power supply is connected to a power supply end of a test cabinet. The test cabinet is electrically connected to a test motor set. The test cabinet is provided with a touch screen, an ammeter, a voltmeter and a junctionbox. A pulley of an active motor is connected to a pulley of a passive motor through a belt. An PLC and an expansion module are electrically connected to a built-in controller, a switching power supply, a loading module, a Hall data acquisition module, a relay, a data acquisition module, a discharge module, the touch screen, the ammeter and the voltmeter. The ammeter, the voltmeter, the switchingpower supply, the relay, the data acquisition module, the discharge module and the active motor are electrically connected to the junction box. The built-in controller and the loading module are connected to the passive motor through wires. The electric vehicle controller automatic test system can realize rapid detection, is accurate in detection data and simple in operation, and facilitates the quick connection and can realize automatic discharge.

Description

technical field [0001] As an important core component of electric vehicles, the vehicle controller needs to be fully functionally tested and tested and corrected for important parameters during the production process. At the same time, the device also has a variety of built-in protection mechanisms. During the test, short circuit, high power consumption, overvoltage, etc. will directly cut off the power and report an error to avoid damage to the controller. In this way, the quality stability and durability of the vehicle controller can be guaranteed, and the stability of the electric vehicle can be guaranteed for a long time. And it can realize fully automatic testing to improve production efficiency. [0002] At present, in the test of the vehicle controller, most of the controllers are tested by using tweezers to short-circuit the corresponding functional connectors, stepping on the load device of the test motor, and then manually observing the changes in the instrument and...

Problems solved by technology

This test method has unavoidable test shortcomings. First, engineers need to test on the bench all the time during the test process, and it is impossible to achieve automatic testing without unmanned monitoring. The test process is extremely cumbersome, and some characteristics such as undervoltage and current are very difficult. It is difficult to measure accurately, and the abnormal current of the test needs to be manually adjusted with a soldering iron. During the test process, human errors may cause mistesting or missed testing; secondly, a single professional engineer can only test a single controller at the same time, and cannot monitor at the same time There is a large waste of human resources for the testing of ten or more controllers
