Data processing method of virtual pile for battery management system test

Abstract

The invention provides a data processing method of a virtual pile for a battery management system test, a charging pile can be simulated to quickly send various messages to a BMS, the returned messages fed back by the BMS can be received and displayed, and the development efficiency can be improved. The virtual pile can connect with the BMS through a CAN card; the virtual pile can be separately driven to execute response operations with the BMS in a handshake start stage, a handshake recognition stage, a charging parameter configuration stage, a charging stage, a charging completed stage; in addition, interactive operations of the above stages can be controlled to be automatically executed in sequence; a message translation module of the virtual pile can translate to-be-sent data to a message appointed by a protocol, and the module also can translate the returned message received by the BMS and can display data obtained by translation or corresponding notice prompt information on an interface. A stage sending module of the virtual pile packages command starting signals which drive virtual pile and the BMS to execute response operations as buttons respectively, and the message sending speed and the correct rate can be improved.

Description

technical field [0001] The invention relates to a data processing method of a virtual pile used for testing a battery management system. Background technique [0002] At present, in the software development process of BMS (Battery Management System), it is necessary to receive or send messages for communication with charging piles. In the prior art, Zhou Ligong’s CAN card and its accompanying message sending program are used to send and receive messages in accordance with specific charging pile protocols. When sending messages, manual operations are required for message writing, data filling, sending and receiving, and translation, and it is impossible to use a computer to simulate the sending of pile charging-related messages received by the BMS. Therefore, it cannot meet the actual testing and upgrading needs in BMS development, resulting in low efficiency of developers, resulting in delayed project progress and long development time. Contents of the invention [0003] ...
