Teaching purpose
The e-Golf power electronic device system components are based on the high-voltage electric control box / main controller of the original e-Golf vehicle. The high-voltage electronic control assembly integrates two-level bidirectional AC inverter motor controller module, vehicle charger module, DC-DC converter module, and high-voltage distribution The training platform has intelligent fault assessment system, which is suitable for the teaching of structural principle cognition and maintenance training of new energy pure electric vehicle in Vocational and technical colleges, general education colleges and training institutions.
Product features
- Modular design: the high-voltage electric control box / main controller assembly adopts modular design. The original vehicle high-voltage electric control box / main controller, AC / DC charging port, cooling water pump of high-voltage main controller, and radiator of the liquid storage tank is fixed on a professional base. The base is designed with a low-voltage signal circuit and high-voltage output line slot, and a high-voltage line is provided with safety signs for identification of the teaching process.
- Retain the original vehicle line connection: e-Golf power electronic device system components are connected by the original vehicle harness, and parallel double plugs for measurement are installed next to each harness plug, which greatly reduces the line loss in the signal detection process. The parallel plug is marked with a pin number, which corresponds to the pin number of the original circuit diagram, so as to meet the requirements for pure electric vehicles in the training process It is necessary to detect the low voltage signal of the electric control box and the main controller. The relevant signals of the high-voltage electric cabinet / main controller are connected with the vehicle 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:
