Problems solved by technology

In this way, the charging function is realized on the surface, but in actual interconnection with electric vehicles or chargers, it may be difficult for the interconnection due to the consistency of protocol implementation, and it is also possible that when the protocol message is abnormal The function is affected, as encountered in the actual test, when the protocol message is abnormal, the device crashes
Therefore, the main problem of the current electric vehicle charger-battery management system protocol testing system and method is that it cannot systematically and comprehensively examine the consistency of the protocol implementation, which brings hidden dangers to the interconnection between the charger and the electric vehicle, and improves the use of electric vehicles.

Abstract

The invention relates to the technical field of new energy vehicles, in particular to a charging pile protocol consistency test system and method, a BMS simulation device is used for simulating a BMSsystem in an electric vehicle to communicate with a charging pile, a message database of multiple protocols is established in the BMS simulation device, various messages are stored in the message database. The protocols to which the messages belong are determined according to the periods, byte lengths and contents of the messages among different protocols, during testing, the BMS simulation devicedetects the messages from the charging pile in the whole process and sends corresponding reply messages to the charging pile by analyzing the contents of the messages so as to carry out dialogue, andafter a complete message reply process is carried out, the BMS simulation device counts all messages from the charging pile and analyzes the messages one by one to determine which protocol each message belongs to so as to judge the consistency of the protocols.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a charging pile protocol consistency testing system and method. 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 vehicles, coordinates a...
