Embodiment 1

[0076] An embodiment of the present invention provides a test method for a battery management system.

[0077] Please refer to figure 1 , which is a schematic flowchart of a test method for a battery management system provided by an embodiment of the present invention, as shown in figure 1 As shown, the method includes the following steps:

[0078] S101. Obtain a target test case of the BMS in response to a test instruction.

[0079] The BMS testing method provided by the embodiment of the present invention can be applied to a BMS testing system.

[0080] Specifically, in the embodiment of the present invention, the target test cases of the BMS may include but not limited to: test items and test targets.

[0081] Wherein, the test target is used to indicate which part of the BMS is to be tested, for example, the entire BMS may be used as the test target; for another example, some units in the BMS may also be used as the test target. The test item is used to indicate which ...

Embodiment 2

[0116] Based on the battery management unit test method provided in the first embodiment above, the BMS test method can be realized by a BMS test system including a VT system, a CANOE system and a vTESTStudio system.

[0117] Among them, the CANOE system is an automotive network development software platform integrating bus simulation, recording and testing. Its integrated test environment provides strong support for the test system construction and automated test process. Specifically, the CANOE system may include: network communication and high-level protocol simulation, test process recording, test script generation, test panel development, test mode and function library integration, etc. The CANOE system can also provide flexible test panel design functions, users can intuitively control the test process and view the status of the BMS system. CANOE system supports different bus types such as CAN, LIN, FlexRay, MOST, J1939 and Ethernet at the same time.

Abstract

A testing method and system for use with a battery management unit: in response to a test command, acquiring a target test case of a battery management system (BMS) (S101); then acquiring a test script corresponding to the target test case, the test script comprising simulation signal information (S102); thereafter, generating a simulation signal according to the simulation signal information (S103); then outputting the simulation signal to the BMS (S104); acquiring state information of the BMS after input of the simulation signal (S105); thereby obtaining a test result of the BMS according to the state information (S106). Therefore, the testing method and system for use with a battery management unit may solve the problem in the existing technology of wasted labor and low test efficiency which are caused by means of testing personnel manually simulating a simulation signal.

Description

【Technical field】 [0001] The invention relates to the technical field of testing, in particular to a testing method and system for a battery management unit. 【Background technique】 [0002] In the prior art, when a battery management unit (Battery management system, BMS) needs to be tested, the tester generally needs to manually adjust and simulate the simulation signals of the BMS that meet the conditions, and manually input the simulated signals to the BMS, in order to realize the test of BMS based on these simulation signals. [0003] In the course of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0004] In the prior art, it is necessary to rely on the testers to manually simulate the simulation signal, and manually input the simulated simulation signal to the BMS. In this way, more labor costs are required, and the accuracy of the simulation signal manually simulated by the tester is relatively low....
