Abstract

The invention discloses a complete-set aging test system and method for circuit boards of an automobile motor controller. An aging box is internally provided with an analog control unit which is used for being connected with a plurality of circuit boards to be tested and performing complete-set aging on the plurality of circuit boards to be tested; the analog control unit is controlled by a monitoring assembly to provide working signals required by the aging test of the plurality of circuit boards to be tested; the read test message generated by the plurality of to-be-tested circuit boards according to the working signals are sent to the monitoring assembly; and the monitoring assembly analyzes the test message so as to judge the aging states corresponding to the plurality of circuit boards to be tested according to the serial numbers of the plurality of circuit boards to be tested and the fault information. Compared with the prior art, complete-set aging of a plurality of circuit boards to be tested in the motor controller can be realized, and the aging fault of the controller can be positioned on a single controller circuit board, so that parallel dynamic aging of the complete-set circuit board is realized, the working efficiency of procedures is remarkably improved, and the aging fault of the circuit board in the controller is positioned.

Description

technical field [0001] The invention relates to the technical field of aging detection of automobile motor controllers, in particular to a complete aging test system and method for circuit boards of automobile motor controllers. Background technique [0002] Due to the pressure of energy depletion and environmental pollution, new energy electric vehicles are more and more popular. Among them, the motor controller is one of the key components of electric vehicles. Controlling the normal operation of the motor is the core of the electric drive system. Therefore, in order to verify the performance of the motor controller, its aging test is particularly important. A good motor controller aging method can evaluate the life and performance of the controller circuit board and improve the reliability of the product. The existing aging test method is to carry out the overall aging of the entire controller of the automobile motor, which cannot achieve the aging of the motor controlle...
