The car can t be charged, what is the reason why the car charger can t be charged?

1. Check the charger, there are two possibilities, the transformer is burned, the line is broken, and the possibility of short circuit is very small.

Second, the charger is in good condition, check the charging connector on the car, is it loose? If so, plug in the plug and flip it a few times, and at the same time see if the charging indicator is on? If it turns on at a certain angle, it means that the charging connector is desoldered and needs to be re-soldered.

Third, the battery aging, replace the new battery, generally for the motorcycle 6V or 12V battery, you can go to the motorcycle repair shop to let the master test the battery (there is a special battery tester) Fourth, the control circuit board is problematic, this is recommended not to check and repair yourself.

The causes of the failure are: fatigue damage of the battery, too long use time; Short circuit inside the battery; The active material on the battery plate falls off, and its capacity is reduced; Vulcanization of battery plates or hardening of negative plates, etc.

Handling of battery failure to charge: first connect the charging circuit firmly, and replace the charger when it is abnormal. When the battery is not charged (that is, there is no current, high voltage is displayed), the battery can be judged to be open.

If the battery voltage is lower than the normal value, the voltage does not rise much during charging, and the battery is still lower than the normal value after being placed for 1h after charging, the internal circuit of the battery can be determined. If the battery is used for a very short time (no more than 1 month), it is a quality failure in the assembly; If the battery is used for a long time and too much powder at the bottom is not observed, it is a short circuit caused by impurity crystallization; If there is too much powder accumulation at the bottom, it belongs to a chronic short circuit in the contact at the bottom of the battery. If the current of the battery is very small when charging, the voltage rises very quickly, up to about a single grid (the normal value is a single grid), the voltage drops quickly when discharging, and the battery is charged early, and the internal heating can be determined, then this phenomenon can determine the sulfation of the battery plates.

This is one of the main reasons why electric vehicles do not charge up.

I don't know what the reason is that the charging hole is not electrified, and I solve the solution

<> "Why Electric Cars Can't Be Charged.

There are 7 reasons why electric vehicles cannot be charged:

1. When the battery life is up, because after the internal damage of the battery, the internal resistance of the battery is larger, which will cause the charging current to become smaller, and the charger mistakenly thinks that it has been fully charged, and the solution is to go to the monopoly to replace the battery.

2. The charger itself is damaged, which is commonly caused by damage to the filter resistance or filter capacitor in the charger, and the solution is to replace or repair the charger.

3. The fuse is broken, if the fuse inside the battery is broken, the battery will be dead, and the solution is to go to the store to replace the fuse.

4. Poor contact, when the contact between the fuse tube and the fuse seat is poor, there will also be a situation where the charging is not charged or the charge is not satisfied, the solution is to adjust the position of the two, so that the contact is good, and the goods are sold messily, so that the problem of insufficient charge or charge can not be charged, if you will not adjust, you can go to the after-sales point to ask professionals to adjust.

5. Poor contact with the power supply, which is a very easy event, according to the survey data, 30% of users will not be charged or not charged because of poor contact with the power supply, the solution is to pull the power supply down, plug it back in, ensure that the contact is not hindered, and then see if it is not charged or not charged.

6. There is a problem with the positive and negative poles, and when the plug-in in the battery is in poor contact or the lead is broken, it will also lead to no voltage, especially whether the connection between the positive and negative poles of the dial is normal and has a great impact on the electric vehicle battery.

7. Open circuit, when the circuit board in the dial is broken, the battery is not fully charged or cannot be charged, it is very normal, the solution is to replace or repair the circuit board to ensure normal contact.

The battery cannot be charged because the battery has a loss of power, and it is easier to activate the battery by the following methods:

1. The battery used in the electric vehicle is composed of multiple batteries, and then the whole group of batteries can be charged in pieces, so that the battery can be woken up to the greatest extent and the battery can be activated.

2. If the battery cannot be charged, you can use the low-voltage charging method to charge the battery, you can choose a charger with a smaller model to charge the electric vehicle, and wait until the battery can be charged into the original charger of the electric vehicle.

3. If the battery has a serious power deficit, you can use a 12V charger to charge each battery, because the battery is placed for too long, so the charging time will be longer. It can also be charged with a charger from a smaller model.

In most cases, it is feasible to use this method, if the battery pack is 60V-20Ah, then you can choose a 48V-20Ah charger to charge, the charging time will take at least two hours for the voltage of the battery to rise significantly, and then you can change to a 60V-20Ah charger for charging.

4. Generally speaking, the battery of the electric vehicle can not be charged because the battery is damaged, in this case, you can use the charger with the repair function to charge, in this case, no matter what the voltage of the battery is, the charger with the repair function can charge the battery, and it is very convenient to use.

5. In the process of daily use of electric vehicles, the electric vehicle battery should not be charged after the electricity is used up, if the battery is in a state of power loss, there is a certain damage to the life of the battery, usually the battery can be charged when half of the battery is used.

The battery cannot be charged for the following reasons:

1. Line problems.

2. Aging of the battery.

3. The battery is short of liquid.

4. Irreversible sulfation of electric vehicle batteries.

5. Battery pack failure.

Hello car battery, it is generally a battery that cannot be charged, and it is recommended to replace a new battery during its service life. It is recommended to choose a camel brand battery with better quality.

Now the car battery is basically a maintenance-free battery, if there is a charge that cannot be charged, it should be the battery scrapped and needs to be replaced with a new one.

If this is the case for you, focus on checking the power storage capacity of the battery, which may be caused by the aging or damage of the battery.

If the car's battery can't be charged, it is likely that the battery is not working, or it is caused by a problem with the wiring.

Hello, the general situation is a generator problem, or it may be a line failure, which requires you to go to the repair shop for specific testing.

The battery is broken.

The battery is aging.

Or there is a problem with charging.

This situation may be the problem of the battery itself, if the substrate inside the battery is disconnected, it will lead to this situation, we first measure whether the power generation of the generator is normal, if the battery is still unable to store electricity, it means that the battery is a problem! The main and most common reason is that the plate is sulfated, which hinders the normal flow of electrons, resulting in the decline of battery capacity and gradual aging.

Regularly check the small holes in the battery cover for ventilation. If the hole is blocked, the gas generated cannot be discharged, and when the electrolyte expands, the battery shell will be broken, thereby reducing the life of the battery.

Check the level of the electrolyte regularly, and add the electrolyte in time when the level level drops.

If the vehicle is not used for a long time, the car should be started every 25 days and run at medium speed for about 20 minutes. Otherwise, the car will be left for too long and will be difficult to start.

The starting time of the car should not exceed 3 to 5 seconds each time, and the interval between starting again should not be less than 15 seconds. The main and most common reason is that the plate is sulfated, which hinders the normal flow of electrons, resulting in the decline of battery capacity and gradual aging.

Regularly check the small holes in the battery cover for ventilation. If the hole is blocked, the gas generated cannot be discharged, and when the electrolyte expands, the battery shell will be broken, thereby reducing the life of the battery.

If it can't be charged, it may be that the battery is damaged, or the charger is damaged, and the controller may be damaged, after this happens, you can replace a charger to try, if it still can't be charged, it may be that the battery or controller is damaged, the controller is an important part of the electric vehicle, this part can control the circuit of the whole car, if there is no such part, the electric car is unable to operate normally, the controller is generally fixed under the rear seat, if the controller is damaged, Can be replaced, this part can be disassembled and replaced separately, if the battery is damaged, then the battery needs to be replaced, the battery is a part used to store electric energy on the electric vehicle, this part is very important for the electric vehicle, if there is no battery, the electric car is also unable to drive normally, but the battery is a wearing part, with the increase of the number of charging and discharging, the performance of the battery will also decrease, so the battery needs to be replaced regularly, if you usually maintain the correct habits of using the car, It can effectively extend the service life of the battery, in the process of using electric vehicles, to prevent overcharging and over-discharging of electric vehicles, when just after riding, do not charge immediately, because the temperature of the battery is relatively high at this time, and immediate charging will make the temperature of the battery continue to rise, which is harmful to the battery.

The batteries used in the car are lead-acid batteries, and if it can't be charged, the main reason is the vulcanization of the plates. For batteries that have been used for a long time (more than three years), there is basically no value in repairing, and it is good to replace them with new ones; If it is a battery that has been used for a short time, the mild vulcanization of the plates caused by over-discharge in a short period of time can be repaired by devulcanization charging, but the capacity of the battery can only be restored to about 80% of the rated capacity.

Introduction to electric vehicle charging: check 1. Check whether the charging socket is normal When charging, check whether the socket of the charging station is working normally, so as to avoid the situation that the charging cannot be charged due to socket failure and looseness; 2. Check whether the charger is normal to avoid charging with the charger in series, use the charger adapted to the electric vehicle itself, and avoid using the charger of other models and models in series, resulting in invalid charging and even damage to the battery of the electric vehicle; 3. Charge frequently to avoid deep discharge of the battery, and the consumption of electric vehicles is relatively large, so you must charge frequently to avoid deep discharge. That is to say, after the electric car is used up, you must remember to charge it, remember to fully charge the battery, and don't wait until it runs out before rushing, which is easy to damage the battery; 4. Remember to close the lock when charging, don't forget to close the lock when charging, try to fill him with charging, pay attention to safety when taking the battery, and don't touch the two sections of the electrode with something or a key with water.

in case of danger; 5. If the electric vehicle is placed for a long time and does not need to be charged regularly, the electric vehicle should also be charged if it is not used for a long time, and it can be charged once every ten days and half a month, because the battery itself will be discharged, so do not place it in the case of power loss; 6. Charge in time, the charging time is at least 1 hour or more when charging, in order to keep the battery safe, pay attention to charging at any time, when there is no power, try not to use it, when the charging indicator is on, it is best to charge for one hour.

Questions. Same as not saying.

All faults to be troubled by loved ones.

Here I can only analyze the reasons with you.

If the car cannot be charged, the battery attenuation is serious. Aging of generator belts. The electrolyte in the battery is dried up, the plates are broken, the plates are short-circuited, and the terminals in the charging line are loose or corroded.

The batteries used in the car are lead-acid batteries, if they cannot be charged, it is recommended to replace them in time. When the battery starts the engine, it provides starting current to the starter, and when the generator is overloaded, it can assist the generator to supply power to the electrical equipment, and when the engine is at idle speed, it can supply power to the electrical equipment, which can protect the electrical appliances of the car.

If the EV charger is faulty or damaged, it will cause the EV to not be charged. The solution is to have the EV charger or replace it with a new one. The internal short circuit of the electric vehicle battery and the blown fuse will cause the electric vehicle to fail to charge.

The solution is to replace the fuse in the battery fuse tube.

Precautions for this debate of electric vehicles

Drivers should always check the circuit plugging points of electric vehicles to prevent ignition and heating of contact points caused by poor contact, and avoid short circuits and string accidents caused by aging and wear of circuits. In the normal use of electric vehicles, there are often all kinds of faults, in the maintenance to choose professional maintenance personnel, do not disassemble and repair without authorization, to ensure that the electrical circuits and protection devices are intact and effective.

Do not put the electric vehicle in the walkway or stairwell to charge, once a fire occurs, the flames and smoke will block the safety exit and escape passage of the building, and personnel cannot be evacuated quickly. During the process of starting and climbing the electric vehicle, pedals should be used to assist the walking, so as to prevent the starting current from being too large and the parts from being overloaded for a long time, causing the motor coil, line, battery and governor to overheat and damage the internal parts.
