XXH-006 Electric Vehicle Main Parts Structure and Performance Demonstration Training Box

About Feature Technical Parameter Basic Configuration

In order to have an in-depth understanding of the main components of electric vehicles, various relays, Hall sensors, temperature sensors, IGBE drive triodes used in electric vehicles are integrated in a training box, which has structures such as dissected relays. The demonstration also has a dynamic action demonstration of each sensor and relay, which truly reproduces the working principle and action process of each major component.

1. Know the structure and composition of each major component by observing the perception of the appearance of the main components of the electric vehicle.
2. By actually measuring the positive and negative electrodes of the battery, it can be known that the lithium iron phosphate battery single cell voltage is 3.2V, and the lithium ion single cell battery is 3.7V.
3. Through the actual operation and measurement, understand the role and use of the Hall current sensor.
4. The temperature sensor is heated by the temperature sensor heating system, and the data is collected through the internal battery temperature management system control board, and finally the temperature change value is reflected on the temperature meter.
5. By measuring the resistance of the temperature sensor during heating, it is found that the higher the temperature, the smaller the resistance of the sensor, that is, the temperature and the resistance are inversely proportional, that is, the negative temperature coefficient.
6. Through the test and measurement of IGBT amplification triode, it is found that IGBT triode has three characteristics of high current, high voltage and high frequency, which can fully meet the needs of DC-AC conversion of electric vehicles.
7. Through the actual measurement of the rotary transformer inside the motor, understand the working principle and advantages of measuring the number of revolutions of the motor.
8. Adjust the rotation speed of the rotary transformer rotor, and observe the change pattern of the input signal waveform and the two sets of output waveforms with an oscilloscope.
9. Actual connection operation and measurement of the main contactor (relay) detection terminal, observe the contact rule of the contact, and whether there is any relationship with the energization direction of the contactor coil.
10. Actual operation and measurement of the motor control contactor (relay), observe the contact rule of the contact, and whether there is any relationship with the energization direction of the contactor coil.
