Why does the display still light up when the electric car key is turned out

Car owners can turn on or off the car lock whistle feature by holding down the key and pressing this mute button next to the car.

On the issue of abnormal noise of automobiles, it is difficult for ordinary car owners to distinguish which ones are abnormal noises and which ones are reasonable abnormal noises. Only nearly 20% of the vehicles that went to the repair shop to detect abnormal noises really had problems. Models equipped with turbocharged engines distinguish between sound and natural suction; Models with engine guards may also make noises due to friction; After some car owners come into contact with different cars, it is likely that due to their lack of understanding of mechanical knowledge, they mistake reasonable abnormal noise as a vehicle failure.

Therefore, learn to distinguish the abnormal noise of the car and avoid wasting time and energy.

How to identify the sound of a car:

In practice, due to the limitations of working conditions, it is difficult to measure the sound of the car with special instruments, and the sound of the car can only be described and compared with the judgment of the sound in daily life. For example, the "rattle" sound caused by the dry friction of the bearing, and the "click" sound similar to the small hammer hitting the cement floor caused by the excessive valve clearance.

1. Correctly distinguish between normal and abnormal sounds.

The vibration of each mechanism in the work of the car will emit a variety of sounds, but the sound does not mean that the car is faulty, in order to avoid unnecessary disassembly, we must first distinguish between normal sound and abnormal noise. The normal vibration sound of each system component (such as the noise on the surface of the engine), the impact sound of the gear when shifting, the air intake sound and exhaust sound of using gas as the working source, and the gear meshing noise are all normal sounds. Abnormal noise (abnormal noise) can be divided into slight noise, general noise and malignant noise according to the impact on the performance of the car.

Slight noise, such as the flashover sound of high-voltage electric leakage, the slight loose sound of rolling bearings, etc., the general volume is small, the degree of wear of the parts is not large, and there is no significant change for a long time, and this kind of fault can still maintain the normal operation of the car without repair.

3. When diagnosing abnormal noise, attention should be paid to creating good auscultation conditions and trying to eliminate the interference of other noises, so as not to affect the accuracy of judgment.

It is best to consciously amplify or reduce the sound, that is, use a screw or other metal rod as a stestological instrument to contact the sound part to amplify the sound, or use a single cylinder fire cut-off to reduce the sound to meet the diagnostic needs. The auscultation site should be kept quiet to minimize human interference.

First of all, check whether the electric lock is faulty, and secondly, check whether there is a string problem in the wiring harness.

This is a normal situation, when the vehicle key is pulled out, the vehicle is not in a state of complete power failure, when the door is closed, press the lock button on the remote control, then the display screen will go out, and the lights in the car will also go out.

The battery life of the vehicle key: The service life is between 3 and 5 years, and the time may be shortened or extended depending on the frequency of use of the vehicle. The vehicle remote key battery uses a button cell battery.

In the after-sales of the 4S store or the general stationery store can be purchased, the replacement of the battery is also very simple, the owner can complete it by himself, when the remote control key is not sensitive, you need to consider what situation will cause the remote control key battery to run out of power for a long time to use the vehicle key, and very frequently, or more than six months, do not use the vehicle key. This will cause the vehicle key battery to run out of power.

When using the vehicle remote control key, you must pay attention to the use of the battery, otherwise it will have a certain impact on the use of the vehicle.

The electric car key is still bright when the display screen is still bright, the key switch is damaged or worn, and the switch fails due to short circuit of the electrical circuit. If the key switch is damaged or worn, and the switch contacts are not cut off after the key switch is turned off, it is recommended to replace the key switch.

If the remote control system of the electric vehicle is turned on and the key switch is unplugged, the electric vehicle can also be uninterrupted. It is advisable to check the remote control of the electric car. The electrical circuit is short-circuited and the switch fails, so it is recommended to find an after-sales service to check the circuit.

Generally, the cars that have such a situation are almost always cars with immobilizers. Of course, in addition to simple electric vehicles, today's two-wheeled electric vehicles are basically equipped with anti-theft devices. If you press the lightning sign twice in a second, which is what we usually call the remote start button, then the car does not need an electric door lock to power up the whole vehicle.

Because the remote control start cable of the immobilizer is directly connected to the positive pole of the battery end.

A remote control immobilizer is installed, and it is checked to see if the "keyless driving button" has been pressed by mistake"Check whether the power key (electric door lock) is faulty, check whether the battery car start lock is short-circuited, check whether the two wires in the electric door lock are broken, and check whether the alarm is short-circuited.

It may also be that the positive pole of the controller or line is connected to the electric door lock wire, but you have just changed the electric door lock, it is very likely that the wire is not connected correctly when the battery door lock is changed, and if the wire is wrong, the electric door lock will appear no matter which gear the instrument is electrified.

There are three main types of drive methods for electric vehicles:

One is in-wheel drive, one is mid-mounted, and one is suspended.

Electric bicycles on the market are mainly driven by wheels, and hubs are better at back-wheel drive, and front-wheel drive performance is relatively poor.

The voltage of the battery is too low to move the motor.

As a green sunrise industry, electric vehicles have been developing in China for ten years. In terms of electric bicycles, at the end of 2010, China's electric bicycles have reached 100 million, and the annual growth rate is 30%. In terms of energy consumption, e-bikes are only one-eighth of those of motorcycles.

1. One-twelfth of a car; In terms of occupied space, an electric bicycle occupies only one-twentieth of the space occupied by ordinary private cars.

From the perspective of development trends, the market prospects of the electric bicycle industry are still optimistic. Electric bicycles have been popular among the middle and low-income classes in urban areas for their inexpensive, convenient and environmentally friendly functional advantages. China's electric bicycles have been growing significantly year by year from research and development to small batches on the market in the mid-nineties of the last century, and production and sales since 2012.

Due to the strong demand, China's e-bike market has been growing by leaps and bounds.

Data show that in 1998, the national output was only 10,000 units, in 2002 it was 1.58 million units, and in 2003, China's electric bicycle output reached more than 4 million, ranking first in the world, with an average annual growth rate of more than 120% from 1998 to 2004. In 2009, production reached 23.69 million units, a year-on-year increase. Compared with 1998, it has increased by 437 times, and the development rate is quite amazing.

The average annual growth rate of electric bicycle production in the above statistical years was about 174%.

Hello! 1. The voltage of the battery is too low to move the motor, 2. The brake of the electric car is not released, 3. The controller.

The wire to the motor is disconnected, 4, and the controller is not matched with the motor.

The subject's question is: the electric car has electricity, and the LCD screen is also bright, but it can't be driven, what should I do?

Hello, this situation is often encountered in maintenance, there is electricity does not go, and the reasons for not going are probably as follows:

The battery head wire is oxidized and corroded, which will cause the overpower to be not strong, and the electricity that reaches the controller and meter is very weak.

Example: A few days ago, there was a 36V electric car, the key meter showed that there was also electricity, but when the OnePlus turned the handlebar, the meter showed that it was undervoltage, and the wheels would not rotate, check the battery, see the battery bulge, look at each battery stigma, one was repaired before, it may be that the battery stigma was broken, and people warped the stigma with tin to solder the wire, and now it is oxidized and corroded here, resulting in insufficient overpower, just connect it back again.

The battery voltage is too low, to reach the under-voltage value of the controller, the controller protection function, below the under-voltage value of the car can not be opened, usually this situation is that you open the key to have electricity, but sit on the power indication directly down to the end, which also leads to the car can not drive away.

The brake power-off switch is not in place, the controller is out of the power-off state, so the car can't be driven, the brake power-off switch is not returned to the reason that the brake handle is broken, the power-off switch spring head can not be pressed, the brake is not returned, the brake arm is rusty, stuck, etc. There is also a brake switch line water ingress and short circuit will be affected.

Solution: Find the place that causes the brake not to return and repair it, and push the brake handle out with your hand until it returns to the brake power-off switch. You can also temporarily cut the brake cord, you can drive away, and then go to the repair department for maintenance.

Find a new handlebar to connect the handlebar at the controller handlebar plug, test run, normal words indicate that there is a problem with the old handlebar or turnbar line.

Pick up the tripod and turn the wheel by hand, if the wheel rotates and is very heavy, then this situation is likely to be the controller is broken, and this needs to be checked to be determined.

First of all, open the seat, find the controller, see if the controller and the motor phase wire are burned together, if there is one, separate it, turn the wheel by hand, if it is normal, test it, if you can open it, wrap it with the burned leather wire, and don't let it stick together.

If there is no scorching, separate the phase wire of the motor and the controller, and rotate the wheel, if the wheel rotates flexibly, it means that the power tube of the controller is burned, and the controller is only replaced.

It is recommended that the subject start with a simple start, and if it still doesn't work, let the car repairer overhaul you.
