Why can t electric cars walk when they have electricity?

As follows: 1: Whether the forward and backward gear operations are displayed (see the display screen).

2: Whether the accelerator pedal is normal (whether the acceleration pedal is well connected with the controller.)

3: Whether the temperature sensor is damaged, whether the plug is unplugged and whether it is driving normally, if it is driving normally, it means that the temperature sensor is damaged.

4: Whether the encoder connection is intact, whether the contact is poor, whether the controller indicator light shows blue after unplugging the encoder, if the encoder is damaged, replace the encoder.

Note: The temperature sensor and the encoder are the two wires connected to the motor, the temperature sensor is two pins, and the encoder is four pins.

Electric vehicle. An electric vehicle (BEV) is a vehicle that is powered by an on-board power supply and driven by an electric motor to drive the wheels and meet the requirements of road traffic and safety regulations. Due to its small environmental impact compared to conventional vehicles, its prospects are widely promising, but the current technology is not yet mature.

Working principle: battery - current - power regulator - electric motor - power transmission system - drive car (road).

Chinese name. Electric vehicle.

Foreign name. blade electric vehicle

Class. Battery electric vehicles (BEVs).

How it works. Drive the car on.

Impetus. On-board power supply.

Those who are doing right, why don't they leave.

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.

1.The battery output is not normal.

The battery output of the electric vehicle is abnormal, such as if the battery output is too low, it will lead to battery failure, and then the phenomenon that the electric vehicle does not run away when it has power.

Solution: Replace the battery.

2.Brake bar problems.

Because the brake lever has a power-off brake, which is commonly known as a brake power-off, if the brake does not return, it will cause the electric vehicle to be energized and not go away.

Solution: Replace the brake lever.

3.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.

4.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.

5.The problem of the turnaround.

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.

The electric car has electricity, but if you don't leave, consider whether the power supply is disconnected.

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.

Answer: (1) 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. (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 the signal line (to put it bluntly, let the handlebar short-circuit), if the car rotates to prove that the handlebar is broken, and it needs to be replaced or repaired urgently, turn on the power and twist the handlebar with a universal meter to measure the positive wire and signal line. (4) Check the quality of the motor, and the carbon brush of the motor is not in contact with each other, which will also cause the electricity to not go. (5) Pull out the brake line, if the car rotates, it proves that the brake lever is broken, and the brake lever must be replaced.

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 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.

The signal source of brake power failure is formed after collecting the action of the brake switch, if the brake switch is stuck or malfunctioning, it will cause the whole vehicle to have electricity and can not go, we can try to brake the car several 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 is in poor contact with the two-wire stamping parts, or if 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.

First of all, when you find that the electric car cannot start, of course, you must check the battery first. At present, the common specifications on the market are 24V, 36V, 48V, 60V, 72V voltage, which can detect 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.

In addition, it is to check the brake wire, signal line and brake switch of the electric vehicle. If the electric vehicle rotates during the short circuit, it proves that the handle is broken and must be replaced or repaired in time.

You mean, ask if the electric car battery has electricity. But he doesn't go. What is the reason? There are several main reasons for this. One. The controller is not in good contact. So from him can not go. Two. He couldn't go back to the brake line when the brakes were powered off.

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.

The vast majority of these problems are caused by brake failures.

Because there is a power-off switch on the brake, every time the brake will be power-off to the motor (note that only the power of the motor is cut off, and the power supply in other places will not be affected), when the brake is not flexible, the power-off switch will not be closed, and it will always be in a power-off state. That is, it is common to have electricity and do not go.

Typically, there are several situations:

1.It is possible that there is a problem with the cable on the battery.

2.The terminal of a certain battery is corroded and loose.

3.Sometimes the cable will be rubbed by other things, etc., causing internal damage to the power cord, which can have the same consequences as corrosion and loosening of the terminal head.

4.The current is not forceful, it can turn when there is no load, but it can't work after load, but the lights and horns can work normally.

5.A section of the power cord is faulty, causing no power.

Virtual electricity does not provide power.

The battery works, but it still can't go, why is that?

There is no reason why the electric car can't go all at once.

I got in the water, and when it was dry, I was able to go.

There are several reasons why the car won't start: one. No oil. Two. Power. Three. No air intake.

Let's analyze these four items approximately:

One. No oil.

The reasons for the failure are:1The oil pump relay is working poorly. 2.The oil pump is not working well. 3.Out of gas.

Fault Detection: 1Detection of oil pump relays:

Turn on the key switch and don't hit the motor, you will hear a click, which means that the relay is working properly! If there is a continuous clicking sound, check whether the tie wire is loose. If the relay is judged to be damaged, the light relay can be interchanged with the oil pump relay.

Drive to the repair shop and buy a new relay.

2.Detection of oil pump: Generally, it is checked with an oil pressure gauge, because it is self-excluded.

There is no oil pressure gauge! The easiest way to do this is to remove the tubing and turn on the key switch on the position. Do not start the motor.

If the oil pipe is injected, it means that the oil pump is normal. On the contrary, it is not normal.

Two. Power. Cause of failure:

1.The head of the battery pile is loose. 2.

The high-voltage ignition coil is damaged. 3.The cylinder line is damaged.

4.Whether the starting relay is plugged in properly or not, it is damaged. 5.

Whether the insurance is burned out. 6.Whether the motor is working properly.

7.Whether the main output cable of the computer case is loose.

Fault Detection: 1Detection of loose battery pile head: observe whether the instrument is displayed, if the whole car has no electricity, open the hood, and observe whether the battery pile head connection is loose and oxidized. Loosen it with a wrench, and pour boiling water on the pile head for oxidation.

2.Detection of ignition coil: You can use a multimeter to check the resistance value of its primary and secondary coils, which should be within the conforming range, and the secondary resistance should be larger than the primary resistance!

But that's not sure if it's in good condition! Unplug the cylinder wire, observe it for flashover, and see if there is any leakage in the insulation! The jumping fire should be blue, and the sparks are thick and long!

3.Detection of steel wire: check the resistance value with a multimeter, which should be within the load range. Unplug the cylinder cord and observe it for a flashover. Or skip the fire and replace.

4.Detection of starting relay: There is a problem with the general relay, and there is no response when hitting the motor. Plug and unplug the relay again to see if it starts normally! Replace the relay or motor shorted.

5.Detection of the fuse: Open the fuse and observe whether the fuse indicator is normal and whether the fuse is burned. Replace the fuse.

6.Motor detection: mainly listen to whether the sound of the motor is normal. If the carbon brush of the motor is severely worn, it can be temporarily activated by hitting the motor with a hammer. Go back to the repair shop for replacement.

7.Whether the main output line of the computer box is loose: check whether the plug-in of the computer box and its wiring and each sensor is loose. Fastening is recommended.

Three, no air intake.

Cause of failure: Damage to the eccentric wheel and wear of the eccentric shaft, resulting in the intake and exhaust valves cannot be opened and closed.

Troubleshooting: Call a tow truck!

Hope, thank you.

Reasons why electric cars have electricity but can't run:

1. Controller damage: The controller of the electric vehicle is damaged, which will cause the electric vehicle to rotate even if there is electricity.

2. Motor failure: If the motor of the electric vehicle fails, such as the unreal contact of the motor carbon brush, 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.

3. The problem of the handlebar: If there is a problem with the handlebar of the electric vehicle, such as the positive pole and the signal line of the handlebar with a short wire short, such as the rotation of the car, it proves that the handlebar is broken, and the broken handlebar will also cause the electric vehicle to not be able to go even if it has electricity.

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.
