How to connect the brake disconnection wire of the electric vehicle controller

The brake power line is generally used with yellow and green two-color wires, and the brake power off is also divided into high level brakes and low level brakes.

The electric vehicle controller is used to control the start, run, advance and retreat, speed, stop and other electronic devices of the electric vehicle motor core control device, it is like the brain of the electric vehicle, is an important part of the electric vehicle.

Motor lock system: in the alert state, the controller will automatically lock the motor when the alarm is given, the controller has almost no power consumption, there is no special requirement for the motor, and there is no impact on the normal implementation of the electric vehicle under battery undervoltage or other abnormal circumstances.

Self-test function: divided into dynamic self-test and static self-test, as long as the controller is in the power-on state, it will automatically detect the interface status related to it, such as the handlebar, brake handle or other external switches, etc., once the fault occurs, the controller will automatically implement protection, fully ensure the safety of riding, and the protection state of the controller will be automatically restored after troubleshooting.

The brake power failure on the controller is generally two wires, and there are also three wires! Some controllers have two brake power-off plugs such a good judgment (two exactly the same color of the line and plug is), the simplest and most direct judgment method, the brake power-off two wires touch a piece of the car power-off, plus the turn of the handle is not to go! Generally, the brake line is (black, green) or (black, gray), there is a purple line that does not need to move, generally a high brake, and the brake power off is generally not burned by the wrong controller,! ~

Summary. Hello, friend. Only one of the brake disconnection wires is a high-voltage power-off, and two are low-voltage power-offs.

Which wire of the electric vehicle controller is the power-off brake cable? How can you tell?

Hello, friend. Only one of the brake disconnection wires is a high-voltage power-off, and two are low-voltage power-offs.

Electric vehicle brake power loss is a purple line. 1. There are two wires on the power-off switch on the brake handle of the electric vehicle, connect the green wire of the break-off switch on the brake handle to the positive pole of the power indication on the dashboard, find a group of plug-ins with black wires and use a multimeter to measure the voltage value below 12V, and use a thin wire to power on the electric vehicle and twist the handlebar lightly to make the motor rotate slowly.

2. After the brake power line is cut, the vehicle will not have the brake power-off function, the rear brake light will not light up when braking, which will pose a threat to driving safety, when the brake power-off function is triggered, the controller stops working, and the power-off does not mean that the vehicle is not energized but that the controller stops output. 3, electric bicycles with its cheap, convenient, environmental protection functional advantages, by the urban low-income class favor, China's electric bicycles from the research and development to the mid-nineties of the last century small batch on the market, to 2012 since the production and sales, has been a substantial growth momentum year by year, due to the strong demand in recent years China's electric bicycle market has maintained a leapfrog growth.

There are two wires on the power off switch on the brake handle of the electric vehicle. Connect the green wire of the disconnect switch on the brake lever to the positive pole of the battery indicator on the instrument panel. Find a set of plug-ins with black lines (be careful, you are not allowed to choose a line with red or black colors in one plug-in).

useMultimeterMeasure its voltage value below 12V, in the electric vehicle energized and light twist the handlebar, so that the motor rotates slowly, at this time use a thin wire, artificially short the two wires of this plug-in, click to stop, is the brake off wire. Connect the black wire of the disconnect switch on the brake lever to the de-energized brake cable of the controller.

First of all, we need to understand that electric vehicle brakes are generally divided into two types, disc brakes.

and drum brakes, while the general electric car is a "front disc and rear drum" configuration. However, no matter what kind of brake, it is a consumable product because it is used every day.

to brake pads. With the passage of time, it will slowly become thinner, and after thinning, there will be a decrease in braking performance, which is one of the main reasons for the failure of many electric vehicle brakes. And at this time, if you want to solve the problem, there are only two options.

The first is to tighten the brake pads to bring them closer to the tires and increase friction.

However, this method is not reliable, because the worn brake pads will become stiffer, which will hurt the tires.

The second is to replace the brake pads with new ones, and this way is more reasonable. Therefore, many repairers choose to replace rather than repair, and this is to prolong the service life and better protect other accessories.

How to connect the electric vehicle brake disconnection wire:

1. The brake line of the controller is generally a single purple one, and there are purple and black together. Did your car not lose power if you bought it, or did it break down later.

2. If it is broken later, just change the brake switch. The brake switch is on 2 lines, and the color is connected to the color.

3. There are two brake wires behind the controller, as long as the two brake wires are put together, the car will be powered off, and the front brake handle also has two wires that have been figured out, and the back controller wires are connected, you just need to connect the back wires to the front brake wires for a long time!

There are two brake wires behind the controller, as long as the two brake wires are put together, the car will be powered off, and the front brake lever also has two wires that have been figured out, and the back controller's wires are connected, you just need to connect the back wires to the front brake wires for a long time!

Summary. Hello, glad to answer for you. Electric vehicle brake light wiring, electric vehicle left and right handbrake parts each have a switch, two switch circuits in parallel, normally open state, one end of the converter output terminal positive (this converter will reduce the battery voltage to the rated voltage of the brake light, generally 12V), the other end of the output is connected to the brake light and the controller respectively, that is, in the handbrake mechanical brake at the same time output signal to the controller to control the motor to stop and provide power for the brake light.

At both ends of the brake light, one end is as mentioned above, and the other end is connected to the negative pole of the converter output terminal. Usually the negative pole of the battery and the negative pole of the converter are connected together to form a common ground.

How to wire the brake light of the electric vehicle, it is the brake power off.

Brake power-off is an important function of the controller, many electric vehicles do not go away with electricity, and it is very likely to be related to it. So when repairing, the first thing we have to do is to eliminate it, and the switch is hidden on the handlebar.

Additional note: Brake power-off means that the brake signal line of the controller receives the corresponding signal, and the controller stops output, and the twist handle has no response at this time. It's not about turning off the power.

There are two types of brake power-offs: high brakes and low brakes.

The so-called high brake is to receive a voltage signal greater than 12V, and the output of the electric vehicle converter is 12V. Generally, it is not connected to the battery voltage, which is not safe.

The so-called low brake is the negative electrode of the low brake line grounding, and the original low brake line voltage of 5V is pulled down to 0V

They are essentially the same, but the connection is different, because the tail lights are lit up when braking. I was fortunate enough to see the schematic diagram of a certain brand of controller, in fact, the high brake is just a relay connected to the low brake, which converts the high level signal into a low level signal and connects it to the low brake.

How to distinguish between high brake line and low brake line.

1.Look at the controller label, but not every controller has it.

2.The high brake is a line, and the controller generally only has a single line for the instrument, and the color of the high brake is mostly yellow, yellow-green; The low brake is two, and the controller generally only has two reversing lines, they are both 5V lines, and the negative pole is connected to realize the function, so you can know it by docking and trying. Note:

The power supply of the alarm is also two, but the red and black wires are fixed.

3.Pinch the brake, multimeter measurement, there is a 12V is a high brake line.

How to wire the power cord and brake light.

It's very simple, just change it in the previous diagram. The tail lights are twin filament bulbs, one for the brakes and the other for the night market lights.

You look at the color of the wiring of the brake light, and you find the brake power cord.

For the electric vehicle brake line, the connection method is very simple, there are two wires or one wire from the controller, directly unload the front left and right brake handles, there is a power-off system line on the brake handle, the line has two wire connectors, one is the negative pole line, one is the high brake or low brake connection line, which depends on whether your electric vehicle is using high electric brake or low electric brake, and the controller should be matched to be connected correctly.

The two wires of the brake lever are distinguished, and most of the current electric vehicles use the brakes on the ground with two broken wires, one is the negative pole and the other is the brake power supply signal line. Only a few cars have three brake wires, which is a special brake handle. The two wires are easy to find, and there is a cable outlet in the middle of the brake handlebar that can be found along this line.

When the brake is powered off, it mainly plays the safety factor of the vehicle brake. When you encounter an obstacle, as long as you brake the brake, pinch the brake brake Minggao to separate the contact of the power-off system, and transmit the power-off signal to the controller, the controller does not work normally, the vehicle will not drive, and the front wheel or rear wheel will brake in time after the brake.

For example, the brake lever and the power-off system must be in contact with the controller cable to use normally.

The brake of the controller is found to be disconnected, and the original electric car is equipped with a high-point brake and a low-point brake. These two parts of the line is easy to find, the original car controller is installed with a high electric brake connection, when you change a controller, you have to check that the original controller is a high point brake on the high point brake line. Messy locust chop.

It is a low electric brake to connect the low electric brake line, some are with a negative electrode, some are without a negative electrode, it doesn't matter, as long as you are officially connected correctly, the debugging is normal, and there is a power-off function, it can be repaired.

This is easier to find, only if you follow the connection line of the front brake lever to find what color is, you can be sure if you have been going along to find what color is connected to the controller. For a new controller, you can connect the low-point brake to the low-point brake according to the indication on the old controller, and the high-point brake to the high-point brake, and it can basically be connected correctly.

The above methods are some of the search methods and wiring methods that I often encounter in repair, and you can check them one by one, this method is also relatively simple, so that it is easy to use. Although the method is simple, it must be carefully searched and not mistaken, if it is a high brake connected to a low brake vehicle will not go normally, or a low brake connected to a high brake is also the same car does not go, must be correctly connected to operate normally.
