The electric car has electricity, and it does not go when it goes: the starter is not in good contact, or the wire is about to break.
1. When the EMU has electricity, it does not go, several possible reasons and corresponding treatment methods:
1. Check the electric vehicle battery.
Whether the output is normal, if the output is too low, it proves that the battery is bad and needs to be replaced urgently.
2. Whether the controller is good or bad can be shorted by the positive 5V of the handle line, such as the turn of the handlebar, it means that the controller is fine, the easiest way is to smell whether the controller has a burnt smell, if there is a proof that the controller is broken.
3. Check the handlebar, use the wire short to connect the positive pole and signal line of the handlebar (to put it bluntly, let the handlebar short-circuit), if the car rotates to prove that the handlebar is broken, replace or repair.
4. Controller handlebar, air switch.
I have changed, the key plug has been tried and I don't need to connect it, the battery wire joints are tight, the distance can run out, the motor has also been checked that there is no problem, the positive and negative electrode solder joints of the power lock, and the red line are soldered, resulting in the car will have electricity and no electricity for a while. Just solder it tightly.
5. Check the quality of the motor, and the improper contact of the carbon brush of the motor will also cause the electricity to not go.
6. Pull out the brake line, if the car rotates, it proves that the brake handle is broken, and the brake lever must be replaced.
Extended information: 1. The battery is a kind of battery, also called a battery, and its working principle is to convert chemical energy into electrical energy. Usually people refer to batteries as lead-acid batteries.
That is, a kind of electrode is mainly made of lead and its oxide, and sulfuric acid solution is used as the electrolyte.
of batteries. 2. Battery refers to the battery that can be used after discharge. There are lead-acid batteries.
nickel-iron batteries and nickel-cadmium batteries, etc.
3. The positive electrode of the lead-acid battery is lead dioxide, and the negative electrode is lead and electrolyte.
It is a dilute sulfuric acid solution. When discharged (used), the positive and negative electrodes react with sulfuric acid to form lead sulfate, sulfuric acid solution concentration.
When it drops to a certain level, it must be recharged.
4. When charging with an external power supply, the electrode and solution can be restored to their original state, and they can continue to be used after charging.

The electric car has electricity, but it can't walk, it must be that the line is broken and you have to go to the repair shop for repair.
-
First of all, when you find that the electric car cannot start, of course, you must check the battery first. Check whether the output voltage of the battery is normal, if the voltage is too low, it is likely to be a battery problem, and it should be replaced in time.

The service life of the handlebar of an electric vehicle is 10-300,000 times, generally 3-5 years. There will be a notification when the handlebar is damaged, and at this time, there will be a flashlight icon on your dashboard that will keep flashing. There are two reasons for the damage of the handlebar, one is that the switch components inside are burned by a short circuit in water, and the other is the high-current discharge that is often screwed to the end, resulting in the burnout of the handlebar.
Thermal expansion and contraction lead to loosening of the line, and poor contact leads to the failure to go when there is electricity. The interface of the electric vehicle wire is basically based on plastic parts, and the plastic itself is affected by thermal expansion and cold contraction is more obvious, and the temperature is high in summer, and the interface expansion is not easy to occur in poor contact, but the temperature is low in winter, and the plastic parts are easy to shrink, and the interface will be loose. It is mainly manifested as a good and bad when twisting the handle.
The controller is damaged, as one of the core components of the electric vehicle, the controller is generally not easy to break, and it will only be damaged in the case of water ingress or poor heat dissipation, the main reason is high temperature. After the control is damaged, the meter screen will be black and the twist handle will be invalid. Workaround:
At this time, you can only replace a new controller, between 150-300 yuan.
-
Electric vehicles can go normally when they have electricity, but sometimes they suddenly don't go, which is generally the reason for this line.
-
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.

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.
-
The essence of whether the electric car can go is the rotation of the motor. Two-wheeled battery car, there is no clutch gear and the like, often are hub motors, and basically brushless, it can be said that the rotor of the motor is integrated with the wheels, as long as the motor can rotate normally, the wheels must be able to go, but the speed is a problem.
If the motor itself coil is burned, of course, the motor will not rotate or rotate abnormally, you can simply measure the motor coil and judge whether the resistance value is consistent. If it is a magnet problem, the current will be very large.
Common faults of electric vehicles.
1. The electric car suddenly ran out of power.
First of all, check whether the power supply has electricity, if not, then check whether the fuse is good, if the fuse is normal, the power supply is dead, then check whether the internal electrode connection of the power supply is loose, whether the battery is broken. If the power supply is powered, check whether the power cord and power lock are normal.
2. The electric car has electricity.
Short the positive red wire and the yellow line of the speed of the controller up, if the motor is running normally, the motor and the controller are good, if the motor does not rotate, the motor is bad or the controller is bad. If the motor and controller are normal and the motor does not rotate, it may be a problem with the handlebar and brake handlebar.
-
1. The controller is damaged
If the controller of the electric vehicle is damaged, the electric vehicle will not rotate even if there is electricity. Solution: Smell the controller for burnt smell, if the controller is really damaged, you need to replace it with a new one.
2. Motor failure:
If the motor of the electric vehicle fails, such as the improper contact of the carbon brush of the motor, it will also cause the electric vehicle to not go when it has power, and the damage to the motor hall will also cause the power to not go. Solution: Repair the motor or replace it with a new one.
3. The problem of turning the handle:
If there is a problem with the handlebar of the electric vehicle, such as using a short wire to turn the positive pole and the signal line, if the car rotates, it proves that the handlebar is broken, and the handle is broken, which will also cause the electric car to not be able to go even if it has electricity. Solution: Replace or repair the turner.
Precautions for riding electric vehicles.
Check the braking distance before riding, regularly check the wear of the brake pads, and replace the brake pads and liners in time. Regularly check the degree of wear and tear of the tires, check the tires for punctures and punctures, and minimize the number of tire repairs to prevent accidents caused by punctures during riding.
When you need to use the motorway to drive and overtake, please look in the left rearview mirror, honk the horn, hit the left turn signal to quickly overtake and then turn the right turn signal back to the non-motorized lane in time. When passing through the bus stop and taxi stand, please observe whether there are any vehicles entering the station before and after, give way three first, pass quickly, and do not stay at the station for a long time.

Electric cars just don't go when they have electricity, for the simple reason that they don't spend a penny to fix them themselves.
-
1. There is a problem with the battery BAI connection cable or battery plug. Generally zhi may be on the battery some.
The connecting cable is loose, or the inner terminal of a certain battery has capacity.
Corrosion loosening. 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 in the middle of the road, 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.
-
The electric car has electricity and does not go, and after checking it, I know that the problem is here.
-
The electric car has electricity, but suddenly it doesn't go, probably because there is a problem with our wiring. We'll definitely check it out before we ride it later.
-
Check whether the square plug on the battery is plugged in, in the place of the left and right brake handles, there is a power-off switch, that is, the brake power-off switch, he has poor contact, mainly because the kill handle is not well returned.
-
I tripped when I opened it, and the switch was quite hot and sometimes it couldn't be closed.
-
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.
-
The train lights are also on, but what is the matter if you don't go.
-
If the contact is poor, you can see if the plug of the battery has been sent!
-
I've had the same problem, well, it seems to be a broken trigger on the battery, or the contact is not working, and I have repaired more than 100 points.

There are three main reasons for the hermit: 1. Turn the handlebar, which directly controls the car to walk. Poor contact, or a problem with the handlebar, can cause this problem money.
Especially on rainy days, it is easy to get water, and there is a high chance of causing this failure. 2. The controller, including its line connection, must not be loose and should be tightened. The controller must be fixed with screws, and many electric vehicle controllers are found to be not fixed during maintenance, and long-term bumps are easy to loosen the internal parts of the controller, causing all kinds of failures.
3. The feedback signal of the motor hall is abnormal. This year, there is a lot of rain, and electric vehicles will enter the water if they are soaked and ridden in deep water for a long time. If the water ingress of the motor is not treated, it will cause internal rust in the long run, which will increase power consumption.

The air switch tripped, the power signal system failed, the brake power loss problem, the controller problem, the fuse problem.
1. The air switch tripped.
If an electric car, whether two-wheeled or three-wheeled, once it doesn't move halfway, the first one should check the air switch. The air switch is easy to trip, if it does, just push it up.
2. Power signal system failure.
The main thing is the fault of the burglar alarm. Nowadays, in order to pursue intelligence and high-end, many electric vehicles are equipped with burglar alarms and keyless driving functions. If there are too many things, it is easy to have problems.
There are too many functions, which can easily lead to complex lines and poor contact. If the electric door lock is damaged and the signal line of the controller electric door lock is not in good contact, turn on the keyless driving function of the anti-theft device, and you can do it.
3. Brake power failure.
If the brake switch is stuck or malfunctioning, it will cause the whole vehicle to have electricity and can't go, we can try to brake the car a few times.
4. Controller problems.
The "Flying Car" function on the controller is to adjust the output of the controller by means of an electric door lock. You can directly short the two wires of the controller, the power cable (thick red wire) and the power signal cable (thin red wire).
5. Fuse problems.
If the fuse blind wire is in poor contact with the two-wire stamping parts, or the whole vehicle has a short circuit problem, it will cause the fuse to blow out. The battery compartment can be removed, and the lid of the compartment can be opened to check whether the fuse is disconnected or short-circuited. If so, you can try shorting it.
It may be that the battery voltage is insufficient, sometimes, the voltage is not enough to mean that there is electricity, and the horn and lights can also be lit, but the starter cannot be brought up. The battery light is on as long as the key is placed in the ON place before the fire is lit. >>>More
