Problems solved by technology

[0002] At present, when using an oscilloscope to test the control logic, there are many restrictions, and it is impossible to visually display the change process of each terminal, module, and parallel contactor. For example, the number of oscilloscope channels is limited (generally 4 channels), and it is impossible to test each module under multi-gun charging at the same time. and parallel contactor control sequence (the number of modules and parallel contactors needs to be tested by dozens of channels at the same time), which puts forward high requirements for testing

Embodiment

[0040] image 3 It is a star ring topology diagram, only displayed figure 2 Module+PCU+charging gun DC contactor status in the system topology, where 1~12 are modules, K1~K15 are parallel contactors in the PCU, 1#gun~6#gun are charging terminals, and Kz1~Kz6 are terminals corresponding to DC contacts device.

[0041] Remark:

[0042] 1. In the system topology, the PCU is the power distribution unit, which controls the module distribution path by closing or opening the parallel contactor;

[0043] 2. The IO board in the system topology controls the closing and opening of the K1-K15 parallel contactors in the PCU by receiving the commands from the monitoring board, and receives its feedback status at the same time.

[0044] The charging terminal will close the main output contactor when charging is started, and the control module will start up and output voltage and current. When one module does not meet the needs of the vehicle, other modules will be assigned to join the ch...

Abstract

The invention discloses a system, method and equipment for monitoring the internal state of a charging system. The system comprises a data acquisition module, a data analysis module, a data storage module and a display module, one end of the data acquisition module is connected to the charging system, the other end is connected with the data analysis module, the data analysis module is connected with the data storage module, and the data storage module is connected with the display module; according to the method, the real-time internal communication message of the charging system is obtained, analyzed and displayed in real time through the topology interface, the related state change curve graph is synchronously drawn, the internal operation state of the charging system is displayed in real time, and the man-machine interaction in the testing process is more friendly; communication message information of the terminal state, the module distribution state, the module output voltage and the parallel contactor driving feedback state is recorded and a curve is drawn, so that the problem reason can be preliminarily positioned.
