There is electricity, but it can t start, and the electric car has electricity but can t start

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.

1. The battery voltage of the car is low; Specific detection method: test the battery voltage with a three-purpose meter voltage level, if it is below 10V, it is recommended to replace it. If it is around 11V, it is barely used; Be prepared for replacement. It can be used above 12V;

2. Check whether it is caused by carbon deposits; If you travel about 20,000 km, focus on checking and cleaning the throttle;

3. Inspect, test and replace spark plugs;

4. Confirm the quality of the gasoline added;

5. Detecting the ignition switch;

6. Test and detect the starter, gasoline pump, sensor and other related components of the starting and oil supply system;

7. After powering on, do not start immediately, wait for 30 seconds to 1 minute, and then ignite; See if it works;

Regardless of any of the above situations, pay attention to the time when the car cannot be hit once, be sure to play again after an interval of 15-30 seconds to protect the battery but not generate power and prolong its service life.

It does not mean that as long as there is gas and electricity, you will definitely get on the car, and there are many that may cause you to not get on the car.

For example, the ignition timing of the engine is wrong, the cylinder pressure is insufficient, the engine is heavily carbonized, low-quality gasoline is used, and the engine mixture is too thick or too thin.

It is still a bluff to discuss the specific situation of the collapse, and there is a correct maintenance idea to gradually eliminate it, and the real cause of the failure will be found.

The electric vehicle has electricity but cannot be started, which may have the following reasons: 1. The electric vehicle has poor contact. 2. The brake is powered off. 3. The power supply circuit is not working. 4. Failure of the motor.

There are several possible reasons why electric vehicles do not go away with electricity and corresponding treatment methods:

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 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, the carbon brush of the motor is not in contact with the real will also cause the power to not go.

5) Pull out the brake cord, if the car rotates, it proves that the brake lever is broken, and the brake lever must be replaced.

It may be the reason why the gear is hanging in D gear and not pushing back to P gear. When the vehicle is first started, the transmission is very strong, and if the gear is hung in the D gear called the driving gear at this time, the instantaneous impact will bring great safety hazards. Therefore, car manufacturers are designed to start the vehicle only when the gears are in P and N gears.

It is also possible that the fuse responsible for starting the motor has burned out.

Automobile fuse is a kind of current fuse, commonly known as "fuse", when the circuit current exceeds 2 times the rated current of the fuse, it will blow in a few seconds, playing the role of circuit protection. It is often used for over-current protection of automotive circuits and industrial equipment.

Burnout phenomenon:

1. The battery has power but the vehicle cannot be started, but it must be noted that when the vehicle cannot be started, remember not to fire continuously, as continuous ignition will cause the battery to continue to discharge and cause the embarrassing situation of complete power.

2. During driving, the vehicle tachometer shows normal, but the speedometer shows zero, and the ABS alarm light lights up at the same time, which means that the fuse corresponding to the ABS is burned out. Some informal businesses will unplug the fuse of the management ABS when transporting vehicles, in order not to increase the mileage, but this brings great hidden dangers.

New energy pure electric, oil-electric hybrid is the use of oil to ignite, the car in the operation of the automatic charging of the battery, and then use electricity to assist the vehicle driving, each has its own advantages, the oil-electric hybrid power is stronger, the driving distance is long, there will be no power, pure electric electricity is used up to charge, it is said that the charging time is quite long. Pure hand-played, hope to adopt!

There are several reasons why a car has power but won't start

1.Mechanical or electrical faults. Poor contact of electronic ignition mechanical switches or switching circuits, or even oil circuit problems can affect the failure of the vehicle to start. Of course, the vehicle must be serviced and tested regularly.

2.There is also a type of vehicle that starts with one button and does not press the brake pedal (or pedals too lightly). For safety reasons, if the engine computer and PEPS system do not receive a brake switch signal, the system will refuse to provide a starter signal to the starter.

3.Faulty spark plugs. The role of spark plugs in car starting is still relatively large.

It's time to replace the car's spark plugs. If it is not enough to replace the spark plug at the first time, it is likely that the engine of the car will be scrapped in advance after a long time. Therefore, the spark plug should be replaced in time.

4.The battery voltage is low or aging. If the battery failure indicator is on, most of it is caused by a low battery, and rarely because of other problems.

You can measure the battery voltage with a multimeter. Most of the voltages are below and it is almost difficult for the car to start. If the voltage falls below volts, the battery will lose power.

If the battery is damaged, it must be repaired or replaced at a repair shop. Ransom Travel.

5.The concentration of the mixture does not meet the standard. If the circuit fault is eliminated, the vehicle mainly checks whether the fuel used meets the requirements, and also determines whether the oil quality is up to standard.

If the concentration of the mixture is not up to standard, it is not conducive to the cold start and heating of the engine. In this case, it is usually a problem with the fuel nozzles, which can be solved by replacing it with a new one.

It is necessary to pay attention to the lack of battery power, otherwise once the battery is de-energized, the life will be reduced by 80%. Of course, pay attention to the battery capacity, and save power for normal driving.

Poor line connection, speed control handlebar problem, brake locking problem, circuit or electronic failure, oil Jianxiang road failure, brake power-off device failure and other reasons will lead to the car has power but cannot start.

How to deal with the car when it has electricity but it can't start:

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

2. Check the controller, you can use the positive 5V short circuit 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 wire, if the car rotates to prove that the handle is broken, it needs to be replaced or repaired urgently, turn on the power and twist the handle with a universal meter to measure the positive pole wire and signal line.

4) Check the quality of the motor, the carbon brush of the motor is not in contact with the real will also cause the power to not go.

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

6. Check whether the spark plug needs to be replaced, generally the spark plug should be replaced once every 40,000 kilometers, but the specific material of the spark attack plug is related, and the platinum spark plug has the longest service life.

7. Check the fuel injector, if the fuel injector has too much carbon or even clogs the fuel injector, it will affect the atomization of gasoline, and there is no way to get on the car, so it is usually necessary to go to the 4S shop for maintenance.

8. Whether the intake pipe is blocked, when the car has electricity but can't turn on, we also have to check whether the intake pipe is blocked, if the intake pipe is blocked, the air can't come in, of course, it can't catch fire, because the combustion of gasoline is oxygen.

There may be several reasons why an electric vehicle cannot start when it is powered on:1. Poor contact of electric vehicles.

2.Turn off the power supply of Sotan brake. 3.

The power supply circuit is blocked. 4.Motor failure.

There are several possible causes of electric vehicle power failure and corresponding treatment methods: (1) check whether the battery output of the electric vehicle is normal; If the output is too low, the battery is broken and needs to be replaced urgently. (2) The quality of the controller can be short-circuited by the positive 5V of the handle wire.

If the handle is turned, the controller is normal. The easiest way is to smell if the controller has burned out, and if it is, it proves that the controller is broken. (3) Check the hand Kai leak Li handle, and use the wire short-circuit handle to stare at the delay pole and signal line (to put it bluntly, it is the short-circuit handle).

If the car turns and proves that the handle is broken and needs to be replaced or repaired urgently, turn on the power, turn the handle, and measure the positive pole and signal line with a multimeter. (4) Check whether the motor is good or bad. Improper contact of the carbon brushes of the motor can also lead to power outages.

5) Unplug the brake line. If the car turns, it proves that the brake lever is broken and the brake lever must be replaced.
