Abstract

The invention relates to the technical field of battery management, and discloses a development method and development device of a battery fault diagnostic program. The development method comprises the steps of detecting battery parameters, and determining a battery state of each battery parameter; determining a transition condition of battery state transition of each battery parameter; adopting the determined all battery states and transition conditions as state modules of a Stateflow model of a limited state machine and state transition conditions among all state modules respectively to establish the Stateflow model used for battery fault diagnosis, and configuring a battery protected code module for each state module of the Stateflow model. According to the development method and development device of the battery fault diagnostic program, a graphical development method based on Stateflow and modularized development thought are adopted, the program logic is brief and clear, the obtained Stateflow model is easy to transplant and upgrade, a test on the Stateflow model is conducted before BMS integral software and hardware finishes, and the BMS software development cycle is shortened.

Description

technical field [0001] The invention relates to the technical field of battery management, in particular to a method and device for developing a battery fault diagnosis program. Background technique [0002] Battery fault diagnosis is an important function of battery management. The battery fault diagnosis program can protect the battery pack under overcharge, over discharge, over temperature, over current and other fault states. At present, the program of lithium battery fault diagnosis generally adopts the "vertical integration" development mode (that is, the development mode that is mainly modularized and then hierarchical) together with the battery management system (Battery Management System, BMS) program. [0003] However, this "vertically integrated" development model has the following problems: [0004] 1) The portability of the battery fault diagnosis program is poor, and it is closely related to the underlying operating system, hardware driver, etc., which increas...
