Problems solved by technology

But the current fast charging test for BMS controller can only be done manually
[0004] That is to say, the existing technology cannot effectively test the fast charging function in the HIL stage. At present, only a rough test can be carried out on the fast charging pile with a real vehicle. Hidden danger

Abstract

The invention discloses a fast charging pile simulation device and system for HIL testing. The device comprises a fast charging pile logic control module which is used for sequentially carrying out the physical connection state confirmation of a charging gun, the insulation detection of a high-voltage loop and the handshake state confirmation of a BMS controller of a vehicle after the insertion ofthe charging gun of a detected vehicle is detected, entering a charging stage after the parameter configuration is completed, and sending a charging notification, and a direct-current charging outputcontrol module which is used for controlling an HIL cabinet to simulate a charging pile to output charging voltage and current after receiving the charging notification. According to the invention, the automatic test of the fast charging function can be carried out through the HIL system, and a more efficient test method is provided.

Description

technical field [0001] The invention relates to the field of automatic testing, in particular to a fast-fill pile simulation device and system for HIL testing. Background technique [0002] At present, the test automation level of many control units is relatively low. For the popular hardware in the loop test system (Hardware in the Loop, hereinafter referred to as HIL), it is a very effective test method that can be as close as possible to the actual use situation. However, at present, when carrying out the full-function test of the new energy vehicle power battery management system (Battery Management System, hereinafter referred to as BMS) controller, the test of the fast charging part is very cumbersome, and it is also a very important part. Only sufficient, timely and effective identification Only by eliminating the failed part of the system can users ensure that users can use fast charging piles to charge electric vehicles normally, thereby avoiding user dissatisfactio...
