9. Supporting embedded new energy vehicle charging system teaching resource package software V1.0, the functions are as follows:
9.1.Based on the national standard AC charging, explain the DC charging principle of electric vehicles in multiple directions through 3D animation model, circuit principle, etc., and show all parts clearly. When learning through an independent system, a separate module can taken out for learning, with clear layers and intuitive and clear.
9.2. The main contents of the teaching resource package include: port definition, charging circuit diagram, charging sequence, vehicle connection, charging confirmation, charging process, stop charging and after-school exercises and other knowledge content detailed analysis.
9.3. Each knowledge system includes knowledge principles, structure display, and circuit demonstration. The circuit demonstration is displayed through interactive animation, and the circuit trend is dynamically demonstrated. A complete circuit diagram is decomposed into multiple circuit diagrams, and the working circuit is learned in sections to improve students' interest, with strong operability, detailed content and smooth demonstration.
9.4. Each module starts with questions, learns with questions, understands the structure of each component, learns its principles, and finally consolidates the knowledge through after-class exercises. The exercises have the function of correct judgment and analysis. The resource package and the company's equipment learning can enhance the understanding of knowledge through practical operation.
10. Equipped with Android+Windows dual-mode fault setting system, which is based on Android (Android) system and wireless network (WIFI). The system is based on Android system and wireless network (WiFi), and the intelligent fault setting and assessment system is designed as an app software that can run on any Android smart phone. Use the WiFi networking function of mobile phone or PC computer to set up wireless communication with the training platform or teaching board equipped with remote fault setting control system module. There are no less than 8 fault points.
11. AC charging is performed by simulating the whole vehicle load through high-power aluminum shell resistance.
