How does an electric vehicle accelerator work? What is the principle of speed regulation of electric

At present, if you search for the electric vehicle accelerator, they all point to the controller of the electric vehicle, so there is no real accelerator, then the working principle of the controller is:

The controller works by turning direct current.

Chop into a square wave.

The peak voltage is almost the same as the battery voltage, so the wavewidth of the square wave becomes the key under the condition that the square wave period is determined.

Controlling the square wave"Duty cycle", you can adjust the average voltage to the motor, and the motor gets the electric power.

The size will also be different. In this way, the speed regulation is realized.

The principle of the electric vehicle accelerator, the introduction of the electric vehicle accelerator - the principle

The controller is divided into different power (that is, the size of the controller) and different voltages according to the model; The controller is mainly to accept the user's control instructions, the energy control from the battery to the motor, the controller is equivalent to the brain of the electric vehicle, the vehicle speed, vehicle condition, the user's control analysis and conversion to achieve the vehicle acceleration, deceleration, stop and other functions, the electric vehicle controller also has a strong protection function, to prevent the electric vehicle from flying and crashing, to prevent the user's power from being too low to ride, to prevent the motor from running out of phase, with the alarm can also be used to start the vehicle remotely, anti-theft lock motor alarm and so on.

There is a management chip inside the electric vehicle controller, written with a software program, according to different customer experience, it is very convenient to adjust at any time, starting strength, starting speed, electronic brake, intelligent delay, timing sleep, fault repair, efficiency matching, noise reduction adjustment can be extended more and more functions, making the user experience of electric vehicle design more humane.

In fact, the principle of the electric vehicle controller is mainly a current control circuit, which is responsible for driving the motor to rotate and can be controlled at any time.

By collecting the accelerator pedal position sensor signal, the rearranged accelerator signal is transmitted to the computer to improve the response performance of the engine, thereby improving the throttle sensitivity, speeding up the starting speed, improving the instantaneous acceleration performance of the vehicle, avoiding the sudden forward movement of the vehicle, and avoiding carbon deposition in the engine. The product has an exclusive design and safety features, which can be customized according to the driving habits and needs of the car owner. And the installation is very simple and quick.

It can be used by simply connecting the cable group with the electronic throttle connector, which can be installed in the entire line of electronic throttle car series! Most of the cars launched at present are designed with electronic throttle, and the depth of the throttle angle will affect the opening and closing of the butterfly mask. It's a fun way to make your ride!

Electromagnetic chuck controller: AC voltage 380V is stepped-down by the transformer and then passed through the rectifier.

After the rectification becomes 110V DC, it enters the suction cup through the control device, and the suction cup is magnetized at this time, and the reverse voltage line is passed into the demagnetization process, and the controller achieves the demagnetization function.

Access Controller: The access controller works in two modes. One is the inspection mode, and the other is the recognition mode. In patrol mode, the controller continuously sends the card reader to the card.

Send a query** and receive a reply command from the card reader.

This pattern is maintained until the card reader senses the card. When the card reader senses the card, the card reader produces different replies to the inspection command of the controller, and in this reply command, the card reader transmits the read proximity card internal code data to the access control controller, so that the access control controller enters the recognition mode.

In the recognition mode of the access controller, the access controller analyzes the internal code of the induction card, compares it with the card data stored in the device, and implements follow-up actions. After the access controller completes the action of receiving data, it will send a command to reply to the card reader, so that the card reader can restore the state, and at the same time, the access control controller will return to the inspection mode.

Energy performance of EMUs

1. Lead-acid battery.

Lead-acid gel batteries) are cheap in cost and stable in performance, and most of the electric vehicles on the market use this kind of battery.

2. Lithium-ion battery.

It is often called lithium battery) with high cost, but has the advantages of large specific energy, high specific power, small self-discharge, no memory effect, good cycling characteristics, wide operating temperature range, and no environmental pollution.

3. Crystalline battery, high cost, stable performance, electric vehicles using this type of battery on the market are not common, only a few businesses to configure this high-performance battery, safety factor.

Highest. The advantages of service life much higher than the first two types of batteries and the advantages of self-healing function are also the leading position in the industry, and the advantages are not possessed by lead-acid batteries, avoiding the disadvantages of lead-acid battery delamination.

Most of the electric vehicle handlebars used on the market are Hall handlebars, and the speed control signal it outputs is a voltage signal, and the output voltage of Hall handlebars depends on the magnetic field strength around Hall components. Turning the handle changes the strength of the magnetic field around the Hall element, which in turn changes the output voltage of the Hall handle. This voltage is then fed into the controller, and the controller modulates the PWM pulse width according to the size of the signal.

In this way, the ratio of the power tube to be turned on and off is controlled to control the speed of the motor.

Now electric vehicles are brushless, the principle of brushless speed regulation is through the single-chip microcomputer in the controller to detect the strength of the output model, and then the change of the signal into the drive signal of the power tube, the power tube to provide the corresponding current to the motor operation, the signal is weak to the output of the corresponding small current motor is relatively slow, on the contrary, the current of the motor will turn faster.
