How to connect the brake line of the electric vehicle, and which two lines of the controller are the

The general maintenance controller will be indicated in the manual, or the E-ABS (brake anti-lock braking system) is indicated, and the common ones are yellow lines and black lines (low brake controllers).

Controller brake disconnection wire confirmation. If the new controller does not have a manual or the reputation on the manual clearly indicates the brake power-off line, the manual experimental method can be used to determine the brake power-off line.

Find a set of plug-ins with black lines (be careful, you are not allowed to choose red and black lines in one plug-in) and use the multimeter.

Measure 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.

Distinguish between high and low level brakes of the 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.

The power-off switch on the brake lever of the electric vehicle is shown belowThere are two lines.

2. Connect the green wire of the disconnect switch on the brake lever to the positive pole of the power indication on the dashboard, as shown in the red line in the figure below.

3. Connect the black wire of the disconnect switch on the brake lever to the power-off brake wire of the controller. Line 7 on the left in the picture below, so it's connected.

Precautions. The purpose of braking is to slow down, either to reduce the speed or to bring the vehicle to a stop. The principle of braking is to convert the kinetic energy of the car into heat energy and consume it, and the kinetic energy comes from the power provided by the engine, which needs to be provided by the work of fuel combustion.

When driving, apply the brakes as little as possible, and braking is only for comfort or in an emergency.

Reasonably reduce the time and frequency of braking applications. The engine has a stagnation effect, in the case of non-emergency, it is necessary to make full use of the engine as much as possible to slow down, when the EFI engine is running passively, the computer will control less fuel injection or even no fuel injection, at this time the fuel consumption is very low, even far lower than the idle fuel consumption.

Generally speaking, one line of the electric vehicle controller is a high-level brake, and two are low-level brakes, and the two are not universal. High level braking is an external input of a brake signal to the controller and brake light.

The low level is that the controller first gives a braking signal (positive pole), and then returns another wire (negative pole) to the controller through the brake to complete the power off.

Similarly, the tail lights are only lit by grounding the negative pole of the brake handle. Therefore, the two can not be used universally, if you have to use it, you need to change the control mode of the bus, and change the negative control to positive control.

The controller brakes and disconnects the wire 2 generally one red and one black, which does not represent positive or negative, which is equivalent to a switch, when braking, the switch is closed and closed, giving the controller a signal. The new brake handle 3 lines, one of which is the middle line, the A line is open, the B line is off, a and B line which is off which is open, measure it yourself, if there is no three-use meter, then connect any two lines to try it.

The low-level control signal is to short-circuit the negative pole of the power supply through the signal line of the controller to stop the controller from working, then the tail light control line can only be the negative pole of the power supply, and in layman's terms, the positive pole of the tail lamp gun is directly connected to the power outlet of the electric lock, and the negative pole of the tail lamp can be controlled with the brake switch.

The simple model is that the power supply passes through the insurance, and then to the brake switch, when the brake pedal is pressed for braking, the switch is connected, and the electricity is sent to two brake lights and a high-mounted brake light, and is connected with the car body through the negative line to form a loop.

The function of the high-mounted brake light is to warn the vehicle driving behind to avoid rear-end accidents. Vehicles without high-mounted brake lights, especially cars and mini-cars with low chassis, are often not bright enough when braking due to the low position of the rear brake lights, and it is sometimes difficult for vehicles following them, especially drivers of trucks, buses and buses with higher chassis, to see clearly.

Therefore, the hidden danger of rear-end collision accidents is relatively large. A large number of research results have proved that high-mounted brake lights can effectively prevent and reduce the occurrence of car rear-end accidents.

There are 2 wires for high battery brakes, 1 for 12v and 1 for 9v, these 2 wires are connected to the high battery brake, and the low battery has only 1 wire The voltage and ground transfer are low battery brakes.

Generally, there are 5 threads, and it is OK to distinguish the color and size.

Add a 48V relay to control the brake light.

Electric vehicles are universal controllers for both 60V and 72V.

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.

Use a multimeter to measure its voltage value below 12V, and turn the handlebar lightly to make the motor rotate slowly, at this time, use thin wires, and artificially short the two wires of this plug-in.

The brake wire is generally used with yellow and green two-color wires:

Brake power outages are also divided into high-level braking, and low-level braking. 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.

The brake handle switch has two functions, one is the rear brake light switch, when you pinch the brake, the switch turns on the brake light and lights up, and the other is that the brake is powered off and the brake is provided to the controller to power off the signal, and the motor automatically loses power when you pinch the brake is safer.

The brakes are powered off! If you pinch the brake handlebar, the power will be cut off, just rely on these two wires!

Summary. 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. High-level braking is to connect the brake wire and the positive pole to the car and not go away (generally the black wire from the positive 12V converter).

Low-level braking is to connect the brake line and the negative pole to the car and not leave. It is to connect the yellow and green wires to one end of the brake power-off switch, and the other end of the switch to connect the black positive wire or negative wire.

There is only one brake line for the electric vehicle controller when it is powered off, but how to connect two wires on the brake handle?

The brake power line is generally used to roll yellow and green to remove the two-color line, and the brake power off is also divided into high-level brakes and low-level brakes. High-level braking is to connect the brake line and the positive pole to the car and not go away (generally the black wire that is shipped with the 12V converter shipped and left). Low-level braking is to connect the brake line and the negative pole to the car and not leave.

It is to connect the yellow and green wires to one end of the brake power-off switch, and the other end of the switch to connect the black positive wire or negative wire.

There is a low frequency line on the controller, as long as there is a positive pole into the controller can be powered off, a wire on the brake handle is connected to the positive pole, (you can be connected to the positive pole on the power indication on the instrument, because it is very close here, it is near the crack on the brake handle) Another wire is connected to the control only shouting device, when the brake handle is pinched, it is equivalent to sending the positive pole to the controller, and the power is off. Some rely on the negative electrode, if it is the source trace negative pole responsibility, on the contrary (prompt you, the green source electric vehicle is negative electrode power off) is generally the positive electrode power off.

Summary. 1. The so-called low brake or high brake of the controller is the meaning of brake power-off. 2. High brake:

The positive voltage of the battery is directly in contact with the high brake line. Low brake: that is, the low brake line is directly connected to the ground, in order to reduce interference, the ground wire is generally selected from the ground wire in the controller, so the low brake is generally two.

3. Generally, electric vehicles use low brakes, and high brakes are not used to suspend in the air, and they can be wrapped with tape. In your case, you can directly connect the two wires of the low brake with the two wires on the brake switch (because it is just a switch, you don't need to divide the positive and negative poles or anything when wiring, and you can directly connect the two wires separately).

There is only one brake line from the electric vehicle brake to the controller, how to connect the controller to the low brake.

Hello, happy to serve you!

1. The so-called low brake or high brake of the controller is the meaning of brake power-off. 2. High brake: The positive voltage of the battery can be directly in contact with the high brake line.

Low brake: that is, the low brake line is directly connected to the ground, in order to reduce interference, the ground wire is generally selected from the ground wire in the controller, so the low brake is generally two. 3.

In your case, it is okay to directly connect the two wires of the low brake with the two wires on the brake switch (because it is just a switch, you don't need to divide the positive and negative poles or anything when wiring, and the two wires can be directly docked separately).

Before, I connected the high electric brake on the control, and pinched the brake to go.

There is only one yellow brake wire on the car to the controller.

Can't you go now?

Pick up the high brake and pinch the brake to go.

Good. After connecting the brake line, you need to pinch the brake before you can go.

The controller brake line will not go when it is connected. It should be that one or two of the two brake switches are damaged, first disconnect the switch on one of the brake handles, and there are two situations after disconnecting, 1, you can go if you are disconnected, and the one that is disconnected is bad. 2, disconnect and don't go, the other may also be a jujube omen is broken, if you disconnect another bench to rent a can't work, so you have to set up another line.

It doesn't work even if it's disconnected, I've tried it.

How to wiring it. That might be a faulty controller, try another one.

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.
