The electric car suddenly didn t respond, what happened when the electric car suddenly ran out of po

First see if the battery plug is plugged in, open the key to see if the instrument is normal, see if you can go to the car, and then remove the two wires of the main switch and screw them together directly, and then see if each instrument is normal? See if you can get in the car? Abnormal is the key switch, under normal circumstances, remove the seat, see if the controller insurance is urged, urge j to directly connect the two wires together, no urge is the controller's business!

Isn't there no electricity in the whole car! The horn doesn't go off, the light bulb doesn't come on! If yes, it's poor contact!

It is recommended to push down the car and kick it twice! Some cars don't work or work! Hehe) check if the battery plug is loose!

Whether the fuse is tightened or not! If there is electricity, don't run! That could be that your killer handle (brake switch) is not in good contact!

There's a power-off switch on the killer handle! These are all manifested in the root of the sudden inability to run!

First of all, look at the power displayed on the display screen, check whether the power cord and battery are plugged in, if not, please plug in a little tightly, if the electricity is still from time to time, then go to the seller to change a power cord, the electric car suddenly does not respond to most of the line problems.

It may be that the wiring on the battery is in poor contact.

In the process of riding an electric vehicle, sudden power outages often occur, is it accidental or inevitable?

I will tell you with my years of after-sales experience. It's a fuse problem

There are 5 possible reasons why an electric car suddenly runs out of power.

First, there is a problem with the wiring of the electric car.

The second is that the battery is broken (there is a virtual battery so the light can be turned on).

The third is that the brakes are not returning.

The fourth is that the controller is burned out by water.

The fifth is the failure of the transfer handle. If the whole car is out of power, it may be that the motor current is too large and the motor has tripped. At this point, power can be restored by disconnecting the circuit breaker under the base.

Suddenly the whole car is out of power, check the air switch and fuse is no problem. At this point, check whether the battery wiring or battery plug is disconnected, or if there is a problem with poor contact. Generally, it can be re-fixed by pulling the wire by hand or unplugging it, and check them one by one.

Batteries are the power of electric vehicles**, and most electric vehicles are currently equipped with lead-acid batteries (low cost and high cost performance). This kind of battery can be recharged and can be used repeatedly, so it is called "lead-acid battery". Lead-acid batteries will be vulcanized during use, and the working environment of lead-acid batteries in electric vehicles also makes lead-acid batteries more susceptible to vulcanization.

Your electric car should be in a place where the circuit has poor contact, such as the electrical contact point inside the key door; the output terminal of the battery; As well as the power connection cable of the control loop, etc., but it is not a big problem, the motor and the battery should be no problem. You can go to the after-sales service to check and repair it.

The electric car suddenly does not go away, but the solution with electricity is as follows:

1. In such a situation, the regulator is damaged and needs to be pushed to the nearest repair shop for repair;

2. The function of the regulator is to adjust the circuit of the whole vehicle, if there is no regulator, the electric vehicle cannot operate normally;

3. Most of the adjusters will be fixed under the back seat.

There are many possibilities for an electric car to not move after it is energized. One is the circuit problem, that is, the line to the motor is broken in the middle. Although the battery has electricity, the motor has no power, so it will not move.

A broken control brake line can also cause the motor to lock up, and the effect of controlling the brake line to break can be the same as that of a brake. You can open the circuit and check it. There are a lot of connectors inside that are bayonet.

Try to plug it in tightly. The wires that connect the motor are easy to find. It is the thickest.

It's also possible that your car was repaired, the line was not lined up well, the skin was worn out during the turn, and then the wire was burned out by the discharge.

If the multimeter also has a power supply, it will be more troublesome. One possibility is false voltage, that is, it looks like there is voltage, but the motor does not start. This is also a circuit problem, that is, the connector in the battery pack is loose and the connection is poor.

Although it can't be overcurrent, it will pull down the voltage when it is overcurrent, so check the battery pack to see if there is an ignition.

The controller burns out: If the battery car has power but can't go, in this case, the first thing to check is whether there is a problem with the controller of the battery car. If you smell a burning smell when you turn on the battery car, it is likely that the controller is burned out, and you should replace the new controller in time.

Battery aging: The battery aging will also cause the battery car to be unable to start after being fully charged, which is due to the fact that the output voltage of the battery becomes low after the battery aging, and the engine of the battery car cannot be started at this time. If it is a problem with the battery, you should find a professional to replace it in time, otherwise there will be potential safety hazards.

Precautions: Electric vehicles should be maintained every three months, the shell of the battery should be installed firmly without gaps, and the dust should be cleaned up in time to avoid dust entering the interior and attaching to the battery. Also pay attention not to release water into the battery, especially in rainy weather, to avoid water entering the battery, causing the battery to be damaged by the phenomenon of battery discharge and charging.

Pay attention to turning on the lights when riding an electric vehicle at night. When it is dark at night, the field of vision is small, if the speed of the electric car is fast, when you see the person in front of you, you may have already walked in front of you, and if you do not react in time, you are likely to hit someone.

Hello! The best troubleshooting method is for the electric vehicle to use if it has power: 1. Unplug the brake lever socket (normally open brake handle).

If the motor is running, it is a brake handle failure, and the brake handle should be replaced. The 5V voltage of the handle source is normal, detect the signal voltage of the handlebar, turn the handlebar, and the signal voltage should change from low to high. 2. Check whether the battery output of the electric vehicle is normal, if the output is too low, it proves that the battery is bad and the battery needs to be replaced urgently.

3. Pull out the brake line, if the car rotates, it proves that the brake lever is broken, and the brake lever must be replaced.

If there is an electric car with electricity, but the electric car does not go. One is the reason for the handlebar, 2 is the reason for the brake power failure, and the third is that the line can also cause electric vehicle failure.

There are 3 points that the electric car does not go a little, 1 point is a short circuit and open circuit, 2 the motor is broken, and 3 the controller is burned out.

There are many possibilities, one is that the brake is broken, the second is that the controller is broken, the third is that the motor is broken, and the fourth is that the handle is not working!

More than half of this fault in electric vehicles is caused by brake power-off, and it can be eliminated by carefully checking the fault of the brake power-off system.

The electric car has electricity, but suddenly it doesn't go, this kind of fault can be eliminated by checking the brake power failure.

Is it not that the brakes are not attributed.

1. The battery car is out of power, which is a common reason for calling the source shirt, so in this case, you have to see if the battery car has power, so that it can't be started.

2. There is a problem with the wiring of the battery car, if the battery car has electricity, it depends on whether there is a problem with the circuit connection of the cavity battery car. If there is a problem with the line connection, the battery car will not start.

3. There is a problem with the handle of the battery car: when there is a problem with the handle of the cracked electric car, there will also be a situation where the electric car does not respond.

Bad behavior refers to unethical and irregular behavior that is contrary to social norms that people recognize and abide by. Primary school students' physical and mental development is unstable, their self-consciousness, independence, self-control, perseverance, sense of responsibility, etc. are relatively poor, and they are easily affected by complex environments. If the family, school, and society do not give correct guidance, it is easy for them to become psychologically unbalanced, have different personalities, and produce undesirable results.

The *****Decision of the Communist Party of China on Deepening Educational Reform and Comprehensively Promoting Quality Education" clearly pointed out that it is necessary to "strengthen students' mental health education, cultivate students' indomitable will and spirit of hard work, and enhance the ability of young people to adapt to social life." The Ministry of Education issued the "Guiding Outline for Mental Health Education in Primary and Secondary Schools", which points out that it is necessary to "help students adapt to the new environment, new collective, new learning life and feel the joy of learning knowledge; Enjoy socializing with teachers and classmates, and experience friendship in humble and friendly interactions. Cultivate a sense of collectivity, be good at socializing with more classmates in class activities, improve a healthy personality that is cheerful, gregarious, happy to learn, and self-reliant, and cultivate the ability to participate in activities independently and automatically."

Primary school is the basic stage of children's development and the key period for the formation of behavioral habits. Schools, families, and society should strengthen education on primary school students' mental health, standardize behavior and habits, and help them form fine character and sound personality.

The display table of the electric car does not go:

1. The problem is not clear, there are two meters of the tram, one is the electricity meter and the other is the speedometer. The speedometer is divided into electronic and geared.

2. If the power meter does not go, there may be no electricity.

3. If the speedometer does not go, it may be that the electric car is in place.

4. The speedometer does not go, it may be that the speedometer line is broken, connect any of the three main lines of the brushless motor to the pulse speedometer line, if there is still no response, you can only change the meter.

5. The power gauge does not go, and the plug is connected.

Or the line, check and repair.

Check that the brake is most likely to have a problem when the power is off, or it is a handle problem, and the controller cable is loose.

2. The air switch trips, just push up the air switch. The reasons for the switch trip are: violent vibration tripping or excessive instantaneous current tripping.

Troubleshooting methods for electric vehicles that do not go away when they have electricity:

1. Unplug the brake lever socket (normally open brake handle), if the motor rotates, it is a brake handle fault problem, the brake lever should be replaced, the 5V voltage of the handle source is normal, check the signal voltage of the handlebar, and the signal voltage should change from low to high when the handle is running.

2. Check whether the output of the electric vehicle battery is normal, if the output is too low, it indicates that the battery is bad and the battery needs to be replaced urgently.

3. Pull out the brake line, if the car is running, it means that the brake lever is damaged, and the brake lever must be replaced.

I've had the same issue as well.

Well, it seems to be on the battery.

One of the triggers is broken.

Or poor contact.

More than 100 repairs.

Electric vehicles can go normally when they have electricity, but sometimes they suddenly don't go, which is generally the reason for this line.

1. There is a problem with the battery connection cable or battery plug. Generally, a certain connecting wire on the battery may be loose, or the terminal of a certain battery may be corroded and loose. The connecting wire will sometimes be rubbed by other things, etc., resulting in internal injuries to the power cord, which will cause the same consequences as the corrosion and loosening of the wiring head, the current is not forceful, it can turn when there is no load, but it will not work after the load, but the lights, horns, etc. can work normally.

If these problems occur, try pulling the wires or plugs by hand and fixing them one by one.

2. The air is turned on and tripped. Once the electric car does not move halfway, the first thing should be to check the air switch. The air switch is easy to trip, if it does, just push it up.

There are two reasons for a switch tripping: a trip with a violent vibration, or a trip with an instantaneous current that is too large.

It is caused by an open circuit or poor contact at the battery output outlet.

Sudden power failure indicator lights are not on, the fault is that there is an open circuit at the previous plug of the controller or a disconnection fault in the battery box, focus on checking whether the battery output plug is loose.

1. The power switch is damaged, resulting in the instrument being unable to be energized normally.

If the power switch has poor contact, or has been damaged, then the electric vehicle instrument will not be powered on properly. In this case, it is generally necessary to check the poor contact of the power cable and repair it. If it still doesn't work, you need to replace it with a new power switch.

Fight boy. 2. The fuse is blown out and the power supply cannot be supplied normally.

In some abnormal cases, the fuse may be blown out, which will lead to the inability to supply power to the instrument normally, so that the instrument is not displayed. In this case, the fault can be solved by replacing the fuse.

3. The battery connection line is not in good contact, resulting in unstable power supply.

Sometimes some users will find that the electric vehicle instrument will be displayed and will not be displayed, in fact, this is caused by poor contact of the battery connection cable. Because the connection line is not in good contact, the battery power supply will be unstable and will not be displayed. For this kind of problem, you need to check whether the cable is loose and reconnect it.

Fourth, the fuse is not turned on, resulting in the instrument not being displayed.

The current new national standard requires that the charging line and the battery output should be equipped with a fuse or circuit breaker, and sometimes the electric vehicle meter does not display, it is Sun Chong because the fuse is not opened. For this case, the solution is also very simple, and reopening it will solve the problem.

The electric car has electricity, but suddenly can't ride the inspection and maintenance method:

1. The built-in battery life is terminated, and the storage capacity is poor.

Stop using to charge, if the green light is displayed at the beginning of charging, open the battery compartment, detect the voltage of each battery, and replace the entire group of batteries if the use time has exceeded two years;

2. The starter is bad or damaged.

It should be inspected to determine that the starter is defective and should be replaced;

3. The battery and starter are normal, and the lock switch is poor.

The car lock is flooded and used for a long time, and it is easy to form a poor conduction of the switch, so replace the new car lock.
