Ⅰ.Product Overview:
The Platform is designed based on BYD E5 battery electric vehicle air conditioning system, and it includes evaporation box assembly, PTC heating control system, electric compressor, air conditioning controller assembly, condenser assembly, central control entertainment system (integrated air conditioning control), high and low pressure pipeline expansion valve assembly, etc., Used in combination with battery electric vehicle power battery management system integrated teaching bench,the platform is applicable to the principle teaching needs of battery electric vehicle air conditioning system in middle and higher vocational colleges.
Ⅱ.Functional Features:
1. This Platform uses BYD E5 original car air conditioning system.
2. The real and operational automobile air conditioning system fully demonstrates the composition structure and working process of the automobile air conditioning system.
- Configure the intelligent fault assessment function: it mainly consists of two independent systems, the teacher fault setting terminal and the student answer terminal, which are installed on the mobile terminal. Teachers can use mobile teaching terminal to connect with the fault setting module of integrated teaching AIDS for fault setting. After the fault setting is completed, students can use the mobile learning terminal to carry out the examination and answer questions. After the examination, the score is automatically stored in the module, which is convenient for the teacher to query the score of each student.
- In order to facilitate the identification and measurement of sensors and actuators, and to reduce plug damage caused by plug removal and insertion of sensors and actuators while restoring the detection scene of the real car, a detection end ≥5cm is required to be placed in parallel beside the plug of the original car wiring harness, and the detection end is made of transparent Acrylic material by laser engraving and flat jet painting, with the same shape as the plane shape of the original car plug. The measuring end adopts a special detection terminal, and marks the number of the measuring Angle and the name of the sensor and actuator. The electrical signals of each sensor, actuator and control unit pin can be detected directly on the measuring terminal, such as resistance, voltage, current and frequency signals. With the help of multimeter and oscilloscope, the parameter changes under various states can be detected in real-time.
- The Training platform frame is assembled by European standard aluminum profile , solid and reliable never change color. There are 4 casters installed at the bottom of the platform frame ,so it is flexible movement, while the casters with self-locking device, so position can be fixed.
- Pressure gauge and temperature meter are installed on the panel of the training platform, which can display the parameter changes of air conditioning pipeline pressure and inlet and outlet temperature in real time.
- The training platform provides a practical working platform for students to practice filling refrigerant and leak detection。
- The panel of the training platform is printed with circuit diagram and configured with detection port. With the help of multimeter and oscilloscope, the parameter changes under various states can be detected in real time.
- The Training platform is equipped with training instructions manual.
