Embodiment Construction

[0069] The present invention will now be described in detail in conjunction with the accompanying drawings and specific embodiments.

[0070] The test method of the invention formulates detailed and comprehensive test content, and uses special protocol test equipment to complete the protocol consistency test.

[0071] The test content is shown in Table 1, including physical layer test, data link layer test and application layer test.

[0072] in,

[0073] The physical layer test mainly examines the communication rate supported by the device under test.

[0074] The data link layer test mainly examines the transmission mode, PGN / PDU identification, check code and link transmission status to ensure that the device under test can give a correct response and operate normally when the link layer is normal or abnormal .

[0075] Application layer testing includes:

[0076] The forward test and reverse test of the charging message mainly examine whether the format and transmissio...

Abstract

The invention discloses a method for testing consistency on a protocol for an electric automobile charger and battery management system. The method comprises the following steps of verifying whether the protocol for the electric automobile charger and battery management system is consistent to a standard or not by using protocol testing equipment; adjusting relevant electrical quantities by using a testing instrument; and testing data accuracy in a coordinating manner. Testing contents comprise protocol consistency testing, application function verification and data accuracy verification; and the protocol consistency testing comprises normal testing and negative testing on charging messages, a charging process and wrong messages. By the method for testing the consistency on the protocol for the electric automobile charger and battery management system, the testing contents are systemic and comprehensive; a technical support is provided for stably and reliably charging an electric automobile; and the method has an important actual significance.

Description

technical field [0001] The invention relates to an electric vehicle charger-battery management system protocol consistency testing method, which belongs to the field of testing and measurement. Background technique [0002] my country's social and economic development is facing severe challenges such as energy supply shortage and ecological environment pollution. Green, energy-saving and environmentally friendly electric vehicles are the main direction of the development of new energy vehicles in my country, and have broad development prospects. As the key equipment for the energy supply of electric vehicles and the two-way interaction with the power grid, the electric vehicle charger is an important basic support for the promotion and application of electric vehicles, and is also an important part of the commercialization and industrialization of electric vehicles. [0003] The electric vehicle charger-battery management system protocol realizes the charging of electric ve...
