Preferably, the terminal of point touch pen has a button, after pressing this button, controlling means receives behind the signal that the button was pressed, recycles when the point touch pen point touches, controlling means can control the alternating current-direct current charging process and suspend on the position of locating now, and the teacher can utilize this to pause and explain this module or alternating current-direct current charging process, until bounce the terminal button of point touch pen, after controlling means received the signal that the button kick-backed, the flow that alternating current charges or direct current charged continued to go on, can pass through the terminal button of point touch pen and adjust the progress as required, more nimble.
With reference to fig. 1 to 2, the operation process of the new energy vehicle charging pile practical training system 100 of the present invention is as follows: the charging practical training system 100 for the charging pile of the new energy automobile is placed, the electric pressure cooker is preheated first, and the air pressure of high-temperature and high-pressure gas is kept constant.
When a new energy automobile is charged in a direct current mode, a 9-hole direct current charging gun is inserted into the direct current charging port module 301, the voltage value of the detection point CC1 changes, the charging pile main controller module 201 judges whether the charging gun is completely connected with the direct current charging port module 301 or not according to the voltage change of the detection point CC1, and after the complete connection is confirmed (at the moment, the voltage of the CC1 is 4V), the 9-hole direct current charging gun is in an unpluggable state; meanwhile, the charging pile main controller module 201 controls the low-voltage direct-current switch module 204 to be closed, after the low-voltage direct-current switch module is closed, 12V auxiliary power is transmitted to the double-circuit power through the A + port of the direct-current charging port module 301, namely, the water lamp 60 from the A + port to the double-circuit power section is turned on, the double-circuit power is activated, the battery management system module 401 and the motor controller module 304 are awakened, and the work indicator lamps of the battery management system module 401 and the motor controller module 304 are turned on. Then, fill electric pile main controller module 201 closed direct current and fill electric pile control switch module 203, after the closure, fill the color-changing pipeline 50 between electric pile main controller module 201 and the direct current and fill electric pile control switch module 203 and change color and keep the normal bright state, and direct current fills the color-changing pipeline 50 between electric pile control switch module 203 to the direct current mouth module 301 and changes color.
Meanwhile, the motor controller module 304 detects the voltage state at the detection point CC2, and when it detects that the voltage at the detection point CC2 is changed from 12V to 6V, the motor controller module 304 sends a signal to the battery management system module 401 through the CAN signal (the water lamp 60 between the motor controller module 304 and the battery management system module 401 is turned on), and then the battery management system module 401 closes the main positive contactor module 3091 (actually, the control device controls the electromagnetic valve on the back side of the main positive contactor module 3091 to be opened, and the water lamp 60 between the battery management system module 401 and the main positive contactor module 3091 is turned on, and the direction is from the battery management system module 401 to the main positive contactor module 3091).
