2. Functional requirements
1. The real and operational new energy power battery charge and discharge assembly fully demonstrates the structure and logical control relationship of the main components.
2. The main components are installed on the platform, and the electrical connection is the same as that of the real car. It can be easily disassembled, allowing students to master the disassembly and assembly points and safety protection of high-voltage system components during the disassembly and assembly process; provide courseware to talk about the main components Function and pin definition.
3. The BMS battery management system is installed on the teaching board, clearly marking the logic control relationships such as voltage acquisition line, temperature acquisition line, relay control line, and Hall current sensor acquisition line.
4. The power battery pack display (7 inch) is installed on the teaching board, you can observe the various parameters of the charging and discharging process, and master the control logic of the power battery pack charging and discharging process and the changing rules of the main component parameters.
5. Rely on the intelligent switch to reproduce the charging and discharging process control logic on the display.
6. The training platform is equipped with a discharge module to imitate the energy consumption process of the vehicle, and the size of the discharge current can be selected.
7. The power battery pack is equipped with a mechanical maintenance switch. After pulling out the mechanical maintenance switch, you can open the upper cover to observe; the high-voltage electrical connectors are made of Shenzhen Basba products and have reliable performance.
8. The translucent design of the power battery pack, with built-in LED lighting, is convenient for students to observe the internal structure of the battery.
9. The training platform is equipped with a 12V power grounding mechanical switch, which can disconnect the 12V grounding at any time and cut off the entire system power supply.
10. The output circuit of the power battery pack is additionally equipped with a mechanical disconnection emergency switch, which is suitable for easily disconnecting the main power circuit in an emergency.
11. The teaching board fully displays the working principle diagram of the power battery pack, charging and discharging, and installs the detection terminal. With the help of a multimeter and oscilloscope, it can detect the parameter changes in various states in real time.
12. The training platform is composed of a platform and a teaching board. The platform is placed horizontally and the main components are installed; 4 casters are installed at the bottom of the training platform to move flexibly, and the casters are equipped with self-locking devices to fix the position.
13. Equipped with an intelligent fault setting and assessment system, the teacher sets the fault, the students analyze and find the fault point, and the main parts are led out of the detection port to directly detect the fault location and master the actual vehicle fault handling ability;
