You can start by connecting this line to the positive end of the bai. The voltage of the switch can then be measured. The main power cord is directly connected with the controller, and the electric door lock is directly connected with the output of the electric door lock.
Of course, the input end of the electric door lock is directly connected to the positive power supply. This connection allows the current to flow through the electric door lock with very little and can extend the life of the door lock.
Many electric motorcycles are connected with this, because the vehicle current is too large, which directly overburdens the electric door lock, and the lock will hang up quickly. If it's a small car, or a car that uses a direct electric door lock to control the power supply of the whole vehicle, just connect the electric door lock cable to the positive power supply of the controller.

You can connect the wire to the positive electrode first, and then measure the voltage to see if there is one. The main power line is directly connected to the controller, the electric door lock wire is connected to the output end of the electric door lock, and the input end of the electric door lock is of course directly connected to the power supply. This connection method makes the current flowing through the electric door lock very small, which can extend the life of the lock.
Many electric motorcycles use this connection, because the current of their vehicle is too large, and if you directly burden the electric door lock, the lock will soon hang up. If it is a small car or the car itself is the kind of car that directly controls the power supply of the whole vehicle with an electric door lock, you can directly combine the electric door lock wire and the positive power supply of the controller together.

Summary. Hello dear, positive and negative poles: 2 roots, thick red, thick black, positive and negative electrodes are all on the same plug, fine red is the lock wire.
Motor wires: 3, coarse yellow, coarse green, coarse blue.
Hall wire: 5, red, black, yellow, green, blue (fine).
The distinction is as follows: Generally, the three-speed plug of the key is the same as the hall plug of the motor, three wires in a row, two wires in a row One of the wires in the two-wire row is a common wire, that is, a negative wire.
The other is the control line, and the three-wire row is the three-gear display line. Use the multimeter to find the common line first and then find the one with positive voltage is the display line, after separating, these two wires are connected to the light-emitting diode or the display wire is connected to the display gear of the LCD instrument, and the remaining three are shorted with the common wire.
If the light-emitting diode or liquid crystal gear is extinguished, it means that this line is the control line, and the remaining two wires are also display lines, which are connected to these three display lines according to the speed of the vehicle.
What is the line of each line of the electric vehicle controller and how to distinguish it?
Hello, dear ask the user, hello, I'm yours, ask the car expert, your question has been received, and the answer is being sorted out for you urgently, please don't worry, typing is slow, about 5 to 3 minutes back, please wait a moment.

Electric Vehicle Controller Line:
1. Power cord 3ay, three wires, red, red, black.
2. The motor line, yellow, green, blue, generally connected to the corresponding color line, if it cannot rotate normally, it needs to be debugged with 36-phase wire connection.
3. Hall signal 6ay: generally the corresponding line corresponding to the street, red, black, yellow, green, and blue.
4. Variable speed line 3ay, three, red, black and green.
5. Brake line 2ay, two. Black, purple.
6. The cruising line is 2ay, which is quite a turning line, red and black.
7. The speed limit is generally white or blue alone, and the two lines are connected, which will limit a certain speed.
The electric motor control system of electric vehicles should choose a more suitable microprocessor system according to the complexity of its control algorithm. The simpler single-chip controller is selected, the complex DSP controller can be used, and the latest motor drive special chip can meet the motor control needs of some auxiliary systems. For electric vehicle motor controllers, it is generally more complex and suitable to use DSP processors.

The generous plug is a special plug for the anti-theft device, and the black is the negative pole for connecting the power supply of the anti-theft device;
Red is the positive pole of the power supply connected to the anti-theft device;
The blue is the detection method of connecting the electric door lock detection line (the electric door opening signal line when driving without key): when the electric door is opened, its output voltage is the same as the positive voltage of the power supply of the anti-theft device;
Yellow is to connect the anti-theft device tire rotation signal line, detection method: when the electric door is opened, rotate the rear wheel, the joint has a 5V voltage output;
The gray line is connected to the signal line of the immobilizer lock motor, the gray generally represents the high-level lock motor, and the blue generally represents the low-level lock motor, the detection method: the high-level lock motor, no voltage output after opening the electric door, the low-level lock motor, there is a 5V voltage output after opening the electric door lock.
The others don't know.

Someone twists the handlebar for you, turns the motor up, and then lets him hold the brake, whichever is fine, and it stops.
And then you unplug everything from the controller that you don't know about, and the motor changes.

With the popularization of electric vehicles, the engines of electric vehicles on the market today use AC motors. The power of the AC motor is provided by the on-board storage battery, which provides direct current to the vehicle through the on-board storage battery, but the normal motor needs AC power to work normally. Therefore, turning direct current into alternating current is the key to the work of electric vehicles.
There are 3 major modules of motor controller.
1. Electronic control module (electroniccontroller): It is a general term that includes hardware circuits and corresponding control software. The hardware circuit mainly includes the microprocessor and its minimum system, the monitoring circuit for the motor current, voltage, speed, temperature and other states, various hardware protection circuits, and the communication circuit that interacts with the data of external control units such as the vehicle controller and the battery management system.
The control software implements the corresponding control algorithm according to the characteristics of different types of motors.
2. Driver: The control signal of the microcontroller to the motor can be converted into the drive signal of the driving power converter, and the power signal and the control signal can be isolated.
3. Powerconverter: It plays the role of controlling the motor current. The power devices commonly used in electric vehicles include high-power transistors, gate-shut-off thyristors, power MOSFETs, insulated-gate bipolar transistors, and intelligent power modules.

Required components: AC contactor, intermediate relay, circuit breaker (air open or knife switch), travel switch, start button, stop button. There are a number of square copper core plastic wires, a float, a metal tube (and the float constitutes a lever), or without a metal tube, with pulleys and nylon ropes. >>>More
The speed can be adjusted by rotating the handlebar, i.e. by hand. >>>More
When there is little power consumption left, charging is generally about eight hours, and the specific car is different, so you have to estimate it yourself. >>>More
