Teaching purpose
The e-Golf high-voltage battery system components are based on the e-Golf original vehicle power ternary lithium battery. The power battery pack truly presents the connection control relationship and installation position between the core components of the power battery pack. The training platform has an intelligent fault assessment system, which is suitable for the teaching of structural principle cognition and maintenance training of new energy pure electric vehicles in secondary and higher vocational and technical colleges, general education colleges and training institutions.
Product features
- Modular design: the power battery composition adopts modular design. The original vehicle power battery is installed and fixed on the power battery professional base. The base is designed with a low-voltage signal circuit and high-voltage output line card slot. The high-voltage line installation is equipped with safety signs, so as to identify in the teaching process.
- Keep the original vehicle line connection: the power battery pack and high-voltage line are connected by the original vehicle harness, and a parallel double plug for measurement is installed beside each harness plug, which greatly reduces the line loss in the signal detection process. The pin number of the parallel plug is marked, which corresponds to the pin number of the original circuit diagram, so as to meet the low-voltage signal of pure electric vehicle in the training process Detection needs. The related signals of the power battery pack are connected with the battery management controller through the original vehicle harness, which can meet the data diagnosis and dynamic data flow reading function in the process of practical teaching.
- Intelligent fault assessment system: it is composed of two independent systems: the teacher fault setting terminal and the student answering terminal. The system is installed on the mobile terminal. The mobile teaching terminal connected with Wi-Fi can connect with the fault setting module of the training platform for fault setting. After the fault setting is completed, the students use the mobile learning terminal for examination and answer, and the results after the assessment are automatically stored in the device execution module, which is convenient for teachers to query the scores of each student. The intelligent fault assessment system also has the functions of password management, fault name editing, assessment time setting, fault typesetting, and fault recovery testing.
- Product process standard: the equipment base frame is constructed with two kinds of integrated all-aluminum alloy profiles of 40mm × 40mm and 40mm × 80mm, which is oil-resistant, corrosion-resistant, and easy to clean. The table surface is paved with a color high-density composite board with a thickness of 20mm. The electrical installation part is manufactured in strict accordance with the EU CE electrical certification standard. The whole set of wiring harness adopts connectors with safety strength up to IP64 military industry level, The harness damage caused by long-term training can be directly replaced in sections to avoid worries
Supporting teaching tasks
Each set of equipment is equipped with a corresponding course resource package, which is reflected in the form of training tasks. Each training task includes six links: task description, task objective, knowledge preparation, task preparation, task implementation, and task assessment. Some examples are as follows:
Training task 1 tool cognition before disassembly and assembly of high voltage battery;
Training task 2: disassembly method and demonstration of high voltage battery protection cover;
Training task 3:the internal structure and composition of the high voltage battery pack ;
Training task 4: power management and vehicle power supply;
Training task 5: temperature sensor fault demonstration and measurement;
Training task 6: demonstration and measurement of single battery failure
Training task 7: internal capacitance and control circuit board;
Training task 8:lithium-ion battery structure characteristics;
