Embodiment Construction
[0020] The fault simulation system of the present invention comprises: a man-machine interactive host computer system (1), a fault control unit (2), and an expandable fault occurrence unit (3). The human-computer interactive upper computer system (1) is a terminal input system, and the user can generate multiple fault or normal signals at the same time according to the needs of use, completely simulating the state of the battery management system when it is working normally. The upper computer communicates with the fault control unit (2) through the CAN bus, converts the commands input by the user into single-chip control commands, and then sends these commands to the fault occurrence unit (3) directly controlled by the fault control unit. The fault occurrence unit (3) is connected with the signal input end of the battery management system and the control command output end of the fault occurrence unit. In addition, the upper computer system (1) can also perform CAN communicat...

The invention provides a fault simulation system used for developing, marking and testing a battery management system, which relates to the technical field of fault monitoring and detection of the battery management system. The invention is characterized in that the fault simulation system comprises a host machine control system, a fault code, a fault control unit and a fault generation unit, wherein the host machine control system is connected with the fault control unit through a CAN bus, and outputs the fault information required by users to the fault control unit, the fault code is connected with the battery management system through the CAN bus, and reads the battery management system, the input end of the fault control unit is connected with the host machine control system through the CAN bus, the output end of the fault control unit is connected with the control signal input end of the fault generation unit, the control signal input end of the fault generation unit is connected with the control instruction output end of the fault control unit, and generated fault signals are connected with corresponding ports of the battery management system. The invention can simulate the generation of various faults and normal values of sensors, actuators and electric connection of the battery management system, in addition, the configurability and the expandability are realized, and the invention has the advantages of convenient operation, convenient observation and the like.
Description
technical field [0001] The fault simulation system used for the development, calibration and testing of the battery management system relates to the technical field of fault monitoring of the battery management system. Background technique [0002] At present, the OBD-II standard has been widely used in traditional internal combustion engine vehicles. The vehicle-mounted OBD-II system must carry out fault diagnosis for each sensor, actuator and subsystem of the electronic control system of the internal combustion engine. There are many types of diagnostic objects and possible faults. Whether in the development process of the electronic control system or the actual production process, it is necessary to debug and verify the developed fault diagnosis function online. The object-in-the-loop test will increase the test cost and bring inconvenience to the manufacture, use and maintenance of the equipment. Therefore, the fault simulation device is applied, which can simulate mo...
