What s going on with a car battery charger not charging

When the car battery loses power, we only need to drive normally for one to two hours before we can restore the normal power. However, some friends reported that even after the car drove a distance, they found that the battery still could not be charged. So, what is the reason why the car battery does not charge, and what is the reason why the car battery does not store power, then we will give you a detailed statement.

If the car battery is not charged, it is likely to be due to deep discharge, that is to say, when the vehicle is turned off, the car equipment inside is still in a working state, resulting in the continuous consumption of battery power. For a long time, it will definitely exacerbate the attenuation of the car battery, and it is not true that the battery does not store electricity when the time comes. Therefore, you must make sure that the electronic devices have been turned off when you park, and I believe you don't want to see this situation (the battery does not store power).

The second is the aging of the generator belt, you must know that the engine directly drives the generator through the belt, and then the electricity generated is rectified and stabilized to directly charge the car battery. Therefore, if the belt is abnormal at this time, it will naturally lead to the situation that it cannot be charged, and it needs to be replaced in time. But this factor basically will not appear, because the car will check the generator belt for you during major maintenance, and if it ages to a certain extent, it will help you replace it with a new one.

My Foton pick-up van.

Do not charge the battery in the car.

The battery is good.

The generator went to check the line where he was normal.

Just don't charge the battery.

How did your car be repaired later, and I don't know what happened when I got on the car, can you tell me if it's a problem with the generator?

First of all, check whether the generator generates electricity.

Then check whether the silicon rectifier is normal.

Then check the battery.

There are many main reasons for the early failure of a vehicle's battery. For example:

1. The first is deep discharge: that is, when the vehicle has stopped, but the lighting or other electronic equipment on the car is still in working condition, so that the battery has been in a discharge state, and the battery service life will be greatly reduced if the battery is in a discharged state for a long time.

2. Electrolyte volatilization caused by overcharging or engine overheating: Since the electrolyte is prepared by special sulfuric acid and distilled water in a certain proportion, when the vehicle engine is overheated, the volatilization of distilled water will definitely be accelerated, so that the proportion of sulfuric acid and distilled water in the electrolyte is not coordinated, resulting in a shortened service life of the battery.

3. The generator belt is too loose and leads to insufficient charging: everyone must know that the generator of the car is to supply power to the electronic equipment on the car during the use of the vehicle, as well as to charge the battery, if the belt on the generator is too loose, it will cause the generator to charge the battery insufficiently, thus affecting the normal use of the battery.

4. The battery has not been maintained for a long time: when the vehicle has not been used for a long time, it cannot rely on the generator to charge the battery, and we need to maintain and charge the battery separately. Long-term parking may lead to the loss of battery power, and if the battery is not maintained, the service life of the battery will definitely be greatly reduced.

Maintenance of car batteries:

1. The car should be driven regularly:

Especially for new cars, it is recommended that the owner drive it regularly, the vehicle is parked for a long time so that the power in the battery slowly decreases, after a long time, it is easy to lose power, you can drive out for a period of time every few days, let the car battery be charged, try to keep the car battery in a full state, it is best to keep it at more than 20 minutes of driving time.

2. Try not to use electricity after the vehicle is turned off

Listening to songs after turning off is a more common phenomenon in the process of daily car use, especially when waiting for others, many people like to listen to songs, in the state of flame-off, the car consumes the power supply of the battery, if it is used for a long time, the power in the battery may be exhausted, and the phenomenon of failure to start, it is recommended that the owner does not use electrical equipment after the vehicle is turned off.

3. Clean the battery regularly

In the daily driving process, you need to clean the battery of the car, you can use a rag to wipe the dust, oil, white powder and other leakage dirt of the panel, positive and negative poles, do not use a wet cloth, if you do not handle it well, it is recommended that the owner go directly to the 4S shop or a professional repair shop for processing.

There is a problem with the circuit related to battery charging, and there are only a few things in this related circuit: the first generator, the second battery, and the third charging circuit. As long as there is a problem with 1 of them, there will be a problem, and which one is the specific one, and if there is a problem, it needs to be designed and measured.

I wish you a prosperous Year of the Tiger and good luck Hello friend, what are the following reasons for car battery not charging? First, if the vehicle battery can not be charged normally in the car, then this is a generator, the power generation is too low or does not generate electricity, this is the need to replace the new generator Second, if the battery is removed to charge, can not be charged, then this is generally the performance of battery aging, this situation needs to replace the new battery under normal circumstances, the service life of the battery is about 3 to 4 years, if it exceeds this service life, it is recommended to replace it in time.

If it's not a connectivity issue.

Batteries are consumables.

It should be the end of the service life.

Let's replace it with a new one.

Wishing you health and happiness.

I feel that I should start from the generator, is the generator's V-belt loose, or the generator does not generate electricity, and the generator is no problem, how about the line contact? Whether there is a scorched place, if not, just see if the battery of the car can be used, professional instruments to measure the battery to see if it can be stored on the battery, can not be charged, then can only change the battery, really can not find the reason, you have to the professional repair workshop, let the professional master help you repair.

1. Long-term parking of the vehicle: During the long-term parking of the vehicle, the power in the battery will be continuously released, and the battery will lose power after long-term parking, and the car cannot be started.

2. Car battery.

Reach the service life: the car battery has a certain service life, when the car is not replaced for a long time, there may be no power, by observing the color in the car battery can judge the use of the car battery, green represents normal, black means that the battery voltage is low, if it is white, it means that the service life of the car battery has arrived, and a new battery needs to be replaced.

3. Engine damage: automobile engine.

When the belt is loose or broken, it can not drive the generator to work, and there is a broken circuit phenomenon, and the generator wire is broken or the joint is loose, and the battery will only be discharged and not charged.

4. Battery electrolyte.

Insufficient: When the electrolyte of the car battery is insufficient, the storage of the battery is insufficient, and the electrolyte will volatilize in the process of daily use, so the owner needs to check the balance of the electrolyte in time, and the liquid level position of the electrolyte should be between the highest liquid level and the lowest liquid level.

5. Caused by the corrosion of the battery pile head: if the car battery is used for too long, the battery pile head may be corroded, resulting in the car battery being out of power, and the battery needs to be checked in time to deal with the corrosion to avoid abnormalities in use and affect the normal use of the car.

There may be several reasons why the car battery suddenly does not charge:

1. The tension of the generator belt is not enough and it is relaxed.

2. The generator condition device is broken and cannot generate electricity.

3. Generator line problems.

4. The battery is self-generated, and the life is long.

5. None of the above, that's the reason for the CPU.

The battery is not charged because of deep discharge, which means that when the vehicle is turned off, the car equipment inside is still in a working state, resulting in the continuous consumption of battery power. For a long time, it will aggravate the attenuation of the car battery, and it is not true that the battery does not store power when the time comes. So, always make sure your electronic devices are turned off when you park.

The car is parked for a long time, resulting in battery power loss: the car is in a state of stopping, but due to the discharge characteristics of the battery itself, the battery will be discharged even if the battery is not used. The other is the alarm device, when the vehicle triggers the alarm system, the power consumption is even greater.

There are also some high-end cars equipped with intelligent remote anti-theft system vehicles, due to the use of GPS positioning technology connected to the battery, it is also more likely to occur the situation of battery power depletion.

The most important thing to maintain a car battery is to develop good electricity habits, such as not listening to the radio loudly, charging the mobile phone, using the charging pump, etc. When the engine is turned off, the battery is easy to lose power for a long time, and the service life of the battery will be greatly reduced if the number of power outages increases.

In order to judge whether it is a problem with the battery or a problem with the charging circuit, you can measure the voltage of the battery in the two states of starting and non-starting, if the voltage is high when the engine is working and the voltage is low when the engine stops working, it means that the charging circuit is charging, but there is a problem with the battery, otherwise the charging circuit is not working.

The car battery suddenly does not charge, what is going on? Personally, I think that if the car battery suddenly does not charge, it may be that the battery has been damaged and cannot be charged.

In this case, you should first check whether there is a problem with the line, and then check whether there is a problem with the battery of the battery, but it is best to ask a professional to overhaul it.

First of all, it is necessary to determine whether the generator generates electricity or not. The life of the battery is generally 3 to 5 years larger. Check whether the battery is damaged. [If you have a problem with the car, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

It could be that the battery is broken or the wiring is not working.

The reasons why the car battery cannot be charged are: such as the electrolyte in the battery is dry, the plate is broken, the plate is short-circuited, etc., the most important and common reason is the sulfation of the plate, which hinders the normal flow of electrons, resulting in the decline of the battery capacity can not work normally and gradually aging.

We suggest that you can prevent the occurrence of car batteries not charging according to the following methods:

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.

Reasons why car batteries do not charge.

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.

Through the above introduction, you know the reason why the car battery does not charge. By the way, we will give some knowledge about the use and maintenance of car batteries and vehicle maintenance today.

When the engine is running at medium speed, the ammeter indicates discharge or the charging indicator light is on, indicating that the charging system is faulty. Here's why.

The connecting wire between the battery and the generator breaks or falls off.

If the generator does not generate electricity, it may be a short circuit or open circuit of the silicon diode, a short circuit, open circuit and lap iron fault in the stator winding or magnetic field winding, the brush is stuck in the brush holder or the insulation of the magnetic field "F" binding post is damaged and the tie iron is damaged.

<>1.Since you want to use a charging pile to charge a pure electric vehicle, the first step is naturally the matching of the charging gun and the charging interface, that is, the physical connection. Therefore, when the charging cable can be inserted into the car normally, it means that the charging foundation has been established, but plugging in does not mean that it can be charged.

The charging interface should also ensure that it can realize the transmission and conduction of large current, avoid socket heating and failure caused by excessive current, and meet the requirements of long service life, safety, waterproof and dustproof. In addition to the physical connection, there must also be a communication protocol between the charging station and the BEV. To put it simply, communication is the process of continuous communication and information exchange between charging piles and pure electric vehicles using "common language", and charging can only be carried out normally when the "mutual compatibility" standard is reached.

2.Possible causes include input/output undervoltage, input/output overvoltage, overtemperature, and short circuit. It is necessary to go to a designated repair station for repair or replacement.

The power battery is abnormally disconnected. The insulation circuit is faulty and the BMS main control box needs to be replaced. If the insulation is too low, check the insulation of the high-voltage line or the insulation of the control box.

The power cord bus is broken and needs to be replaced. The fuse blew out and needed to be replaced. The temperature of the battery pack is too high, the cooling fan is faulty, check the rear fan and replace it.

The temperature sensor is faulty and needs to be replaced. The current display is abnormal, the current sensor is faulty, and the current sensor needs to be replaced. The display is faulty and needs to be replaced.

3.When troubleshooting hardware faults, first check whether the charging fuse circuit and relay of the electric vehicle are normal. If everything is fine, continue to check that the charger unit is reasonably outputting 12 volts.

After the voltage display is normal, you can more accurately judge whether the charger is in good condition. However, if the voltage display is abnormal, it is necessary to replace the charger of the electric vehicle in time. If there is still a fault after replacement, the maintenance personnel can further check whether the connectors of each part of the hardware are connected correctly and intact, and if necessary, unplug the connector and reinstall it.
