If you can t charge it for 12 hours, why is it not enough to charge an electric car for 12 hours?

Dear Lenovo mobile phone users, hello!

I'm sorry for the inconvenience caused to your use,LenovoK860The normal charging time is2-3 hours,If it exceeds this range,And it can't be full,Please refer to the following suggestions:1、Please use the original charger and data cable for charging,If it is the original accessories for charging,If possible, you can replace other data cables to try,In order to rule out the abnormal cause of accessories; 2. It is recommended that you try to change the charging environment, and it is best to use the power supply for charging to avoid unstable voltage and current; 3. If you are powering on the phone for charging, please close the background program or restart the device for comparison, it is not excluded that the background program will consume more power; 4. It is recommended that you compare the charging in the standby state or the shutdown state to avoid charging the model while operating, which will generate the corresponding power consumption during operation, so as to prolong the charging time; 5. If it is invalid, it is recommended to try to restore the backup data to factory settings (please pay attention to back up the body contacts and short messages, otherwise there is a risk of loss), if the above operations cannot be solved and improved, it is recommended that you go to the Lenovo maintenance site in time for testing and maintenance. Lenovo authorized repair site inquiry.

The business hours of the maintenance site are usually from 9:00 to 18:00 from Monday to Sunday, and the stations will be slightly adjusted according to their own operations.

First of all, it is necessary to look at the charger and the charging circuit of the electric vehicle There is no problem, it may be that one of them has a problem, resulting in a long time of insufficient charging.

If you make sure that there is no problem with the above two, it may be a problem with the battery of the electric vehicle. You can check whether the battery is soldered or fused, and if so, you can re-solder or replace the battery.

If there is no problem with the battery, then you need to go to the after-sales or maintenance department to check which components of the electric vehicle have problems.

This can only be detected by professionals and professional testing.

The electric vehicle charger has a control circuit inside, and the light jumps when it is fully charged, and sometimes it will malfunction, and the light does not flip when it is fully charged. At this time, you have to unplug the power by yourself. It is a newer battery, which can be charged for up to 10 hours, and it is best not to exceed this time period.

In the case of normal output of the charger, it is likely to be caused by the lack of liquid in the battery, see if the battery is seriously heated, and the battery will be charged for a long time.

There could be the following reasons:1. The converter of the charger.

Damaged, can not be converted and charged, replace the charger resistor.

2. The battery is welded with a multimeter.

Check for stuffiness. 3. The charger insurance burns out, and the charger is replaced.

4. If the power cord and the battery socket fall off and the contact is poor, check and replace.

Battery precautions:

Electric vehicle batteries.

When you buy a new one, the battery will not be too full, as a consumable.

The store will often charge and maintain the new battery, unless you buy an old battery or an inferior battery. In the process of using, we can roughly estimate the distance that can be run according to the dashboard, so as to avoid the embarrassment of the power-off trolley.

Generally speaking, when the electric vehicle power display has reached the last grid of the book, it is ready to be charged. If the last trace of power is exhausted, it is easy to damage the life of the battery, many people are used to exhausting all the power before charging, but this will make the battery over-discharge, and the life is often less than half a year.

Summary. Hello, don't click to end, I'm textual to give you the full answer, 2-3 minutes.

Hello, don't click to end, I'm textual to give you the full answer, 2-3 minutes.

In this case, if it is charged normally for more than 12 hours and is not fully charged, then such a problem is mainly caused by the discharge inside the battery itself. This needs to be tested by the pure waiter, if the internal discharge of the battery is too noisy, then it needs to be replaced. If it is a new car and the first charge is more than 12 hours, this is normal and there is no problem.

Summary. First of all, you can check the problem of the charger, if the charger is still charging after charging for 12 hours, it may be that there is a problem with the charger, even if the battery is fully charged, the light will not jump; At this time, you can choose to change to a charger of the same model, if the display is normal after replacing the charger, then you can change the charger and continue to use it.

If the charger is still not fully charged for 12 hours after replacing the charger, then it should be a problem with the electric vehicle battery. It can be checked from the following aspects:

1. The battery fuse is blown or the battery connection line is in poor contact.

2. The battery is aging and bulging.

In either case, the battery needs to be replaced in time to avoid unnecessary trouble.

What should I do if the electric car is charged for 12 hours and is not fully charged.

Hello! I am your automotive consultant, a special guest teacher, and the cumulative service has exceeded 10,000 people.

You're good, I'm glad Chailing can answer for you. I've seen your question, I'm typing the answer, it takes a trillion to type, please wait! 

If you charge for 12 hours, the charger shows that it is still charging in Huaisou, it may be that there is a problem with the charger, even if the battery is fully charged, it will not jump the light; At this time, you can choose to change to a charger of the same model, if the display is normal after replacing the charger, then you can change the charger and continue to use it. If the charger is still not fully charged for 12 hours after replacing the charger, then it should be a problem with the electric vehicle battery. It can be checked from the following aspects:

Is there anything else you would like to consult? If not. Ma Pai Judgment is bothered, please help me like the spring sky.

Have a great day. Thank you!

If the car battery is not fully charged for 12 hours, it means that the battery charging voltage is not enough, or the battery is faulty.

When the mileage of the car battery reaches more than 50,000 kilometers, and it has not been fully charged for a long time, it means that the battery has aged and needs to be replaced with a new battery in time.

Attention needs to be taken when replacing the battery with a new one.

Need to choose the same model of battery, otherwise it can not be used normally, and in the process of battery replacement, you need to pay attention to the connection sequence of the positive and negative poles, the model of the battery can be queried through the manual of the car, at present, China's domestic battery brands are extraordinary, sail, Zhengye, etc., according to the different models of ** generally around 200 yuan to 1000 yuan, if it is an imported car, the battery ** will be slightly higher.

It may be that there is a problem with the battery. In fact, the service life of an electric vehicle is determined by the electric motor, followed by the battery; Generally, the motor has quality assurance, and it can be used normally; However, if the battery is used and charged improperly, the service life will be greatly reduced; Therefore, the use of the battery is specially introduced, and the following are the key points of the use of the battery: When the battery is stored, it should be stored after it is fully charged, and it should be taken out for discharge or used once or twice in about a month, and then charged and continued to be stored; This is conducive to prolonging the service life of the battery; Generally, the first three charges of a new battery are best in 8-12 hours, and then it can be mastered in 6-8 hours; It doesn't matter how fast or slow the battery is charged; The key is the discharge time; It can be used for a long time after discharge; As long as the battery can be charged and discharged, it can continue to be used; If you buy a big domestic brand, you can; If you can identify the quality of the product, you can also buy the brand products of small and medium-sized manufacturers; This is more cost-effective; Battery bulging is generally due to air leakage and deterioration, and it is usually the beginning of being unable to continue to use (because some less serious, or better quality batteries can still be barely used); If the battery is bulging, it has no effect on the life of the device; However, some batteries are prone to bursting after the bulging; In the small space of the equipment, it is easy to damage the equipment; Therefore, do not use the battery after the drumming; Generally, the life of the battery is determined by the number of times it is charged and discharged; Generally, the number of recharged batteries for repair and refurbishment is about 50 times, so when you buy, you will swear to tell you that the warranty is three months or half a year; Once the warranty period is over, it will definitely not be long; The number of charging and discharging of batteries produced by ordinary manufacturers is about 100-180 times; The term of use is about one to two years; The battery charged and discharged by a good manufacturer is about 200-300 times; The term of use is about two to three years; The imported and original batteries can be charged and discharged more than 500 times, and the service life is longer; The most taboo of general batteries is overcharging and overdischarging; As long as these two principles are followed, the maximum use and maximum service life of the battery can be used.

There are mainly the following reasons:1. The converter of the charger is damaged and cannot be converted and charged, replace the charger resistor.

2. The battery is welded with a multimeter.

Examine. 3. The charger insurance burns out, and the charger is replaced.

4. If the power cord and the battery socket fall off and the contact is poor, check and replace. Trouser legs.

Introduction:

A battery is a type of battery, also known as a storage battery, which works by converting chemical energy into electrical energy. Usually the battery referred to by the gods refers to the lead-acid battery, that is, a kind of electrode mainly made of lead and its oxide, and sulfuric acid solution as the electrolyte.

of batteries. A battery is a battery that can be recharged after discharging. There are lead-acid batteries.

nickel-iron batteries and nickel-cadmium batteries, etc. The positive electrode of a lead-acid battery is lead dioxide, and the negative electrode is lead, the electrolyte.

It is a dilute sulfuric acid solution.

When discharging (using), the positive and negative electrodes react with sulfuric acid to form lead sulfate, and when the concentration of sulfuric acid solution drops to a certain level, it must be charged. When charging with an external power source, the electrode and solution can be restored to their original state, and they can continue to be used after charging.

Summary. The reason why the battery is not fully charged after 12 hours is that the voltage of the battery charging is not enough, and the battery is aging. The voltage of the charge is not enough

If it is a 12V car battery, the voltage should be around when charging. Once below that voltage, it will be difficult for the battery to be fully charged.

What's going on with the battery heating up while charging.
