What to do if the battery does not charge, what to do if the battery does not charge

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.

The battery is damaged. The battery needs to be replaced.

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, electric vehicle batteries.

Try not to run out of electricity and then recharge, 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.

The car battery cannot be charged, and the fault channel is checked as follows:

1. Battery leakage.

Fault phenomenon: common leakage phenomenon: first, the seal between the upper cover and the bottom groove is not good or due to collision, and the sealing glue cracks and causes leakage; the second is acid leakage from the cap valve; the third is acid leakage at the terminal; Fourth, acid leakage occurs in other parts.

Inspection and treatment of faults: first do a visual inspection to find out the location of acid leakage. Take the cover piece to see if there are traces of acid leakage around the cap valve, and then open the cap valve to observe whether there is any flowing electrolyte inside the battery.

After completing the above work, if no abnormality is found, an air tightness test should be done (put it in water to inflate and pressurize, and observe whether there are bubbles in the battery and emerge, if there are bubbles, it means that there is acid leakage). Finally, during the charging process, observe whether there is a flow of electrolyte generated, and if so, indicate the cause of production. If there is a flowing electrolyte during the charging process, it should be drained.

Second, the battery cannot be charged.

Fault phenomenon: first check whether the connection of the charging circuit is reliable, check whether the connection between the wire and the plug is intact, carefully check whether the socket and plug have the phenomenon of "ignition" arcing, whether there is line damage and disconnection, etc.

Check whether the charger is damaged and whether the charging parameters meet the requirements: that is, the initial charging current reaches only; The maximum charging voltage reaches only, the charging floating charge conversion current reaches only, and the floating charge voltage reaches only.

Check whether there is any drying phenomenon inside the battery, that is, whether the battery is seriously lacking liquid, and also check whether there is irreversible sulfation in the plate. The irreversible sulfation of the plates can be determined by measuring the change in the terminal voltage of the plate by charging and discharging. When charging, the voltage of the battery rises very quickly, and the voltage of some single cells is particularly high, which exceeds the normal value a lot; The voltage drops particularly quickly during discharge, and the battery stores no or very little power.

In the above situation, it can be judged that the battery has irreversible sulfation.

Fault inspection and treatment: first connect the charging circuit firmly, and replace the charger if it is abnormal. The dry battery should be supplemented with pure water or sulfuric acid, and the battery capacity should be repaired, charged, and discharged.

If irreversible sulfation is found, an equalization charge should be performed to restore the capacity. The maximum current should be controlled for the maintenance and charging of the dry battery after liquid filling, and the voltage of the three batteries should be above for 10-15 hours. If the voltage difference between the batteries is exceeded, it means that the batteries have been irreversibly sulfated out of sync.

For batteries that have irreversible sulfation, the entire battery group needs to be replaced or the battery needs to be activated.

It has been in the case of power loss, and the battery will be damaged and unusable after a long time.

The battery cannot be charged because it has not been charged for a long time, and you can go to the car repair shop to charge the high-voltage battery once and then charge it normally.

Maybe it's because the battery is broken, right?

You go to your local garage. Let the family take a look.

Replace a new battery with a high key can be solved, 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 is still in a working state, resulting in the consumption of battery power, for a long time will definitely aggravate the attenuation of the battery, when the battery does not store power, it is not true, in general, when the parking must ensure that the electronic equipment has been turned off.

How to charge the vehicle battery when it is dead?

If the car battery is not connected to all electrical components and has no other load, it will also damage about 1% of the electricity consumption every day, which is also the lithium battery life rate of the car battery.

Generally, the upper and lower batteries of the vehicle will be out of power for 2 months, and the battery will be out of power, which may endanger the application of automobile ignition and vehicle interception machinery and equipment.

If the battery is out of power and the car cannot be ignited, the charger can be used to charge the battery, and the battery jumper can also be selected to charge the battery. The battery electrodes of the two cars are connected with data cables, and then the other car is run so that the engine is idle at a high speed.

Then learn to run your car, if the battery is out of power, the car should be able to start quickly, and then the generator set will charge the battery.

When it comes to car generator battery charging, when the car battery is low but can still run the vehicle, it can also be charged with the help of the generator set under the condition of the vehicle.

There is a body part connected by several transmission belts under the engine cover is the generator set of the vehicle, after the engine is turned off, along with the operation of the automobile engine, the generator set is pushed to work, resulting in the amount of current, and the amount of current flows through the car regulator pipe to become electrical, and part of it will be given to the car household appliances application, and the unnecessary part will charge the battery.

The following are the reasons why the car battery is not charged: 1. Deep discharge: When the vehicle is turned off, the on-board equipment inside is still in a working state, resulting in the power of the battery being consumed.

This will exacerbate the attenuation of the car battery, and the battery will not be charged. So make sure your electronic devices are turned off when you park. 2. Aging of generator belt:

The engine is directly driven by the belt, and the generator is rectified and stabilized to directly charge the battery. If the belt is abnormal, it will not be charged and it will need to be replaced in time. Mould return.

Reasons why the car battery is not charging:

1.Unreliable connection of the charging cable: The power cord has fallen off from the battery socket and has poor contact. The charging cable connection is unreliable and the line is damaged. Just reconnect the charging cable. If the line is damaged, it must be replaced.

2.Damaged charger: The internal parts of the charger are short-circuited or damaged, and a new charger needs to be replaced.

3.Lack of liquid or damage to the battery: The battery is not liquid or pure enough, and excessive lead sulfate is deposited on the internal plates of the battery, resulting in an increase in the internal resistance of the battery and a decrease in capacity. Pure water needs to be replenished, then repaired, charged, discharged to restore battery capacity, or replaced.

4.Battery vulcanization. The batteries used in automobiles are all lead-acid batteries. For batteries that have been used for a long time (more than three years), there is basically no repair value. Just replace it with a new one.

If the battery is used for a short time, due to short-term over-discharge, the electrode sheet is slightly vulcanized, which can be repaired by desulfurization charging, but the battery capacity can only be restored to about 80% of the rated capacity.

The reasons why the battery is not charged are: 1. The battery attenuation is serious; 2. Aging of generator belt:3. The electrolyte in the battery dries up, the plate is broken, and the plate is short-circuited; 4. The terminal is loose or corroded in the charging line, which increases the resistance and decreases the current intensity. 5. The plate of Brother Shen's battery is vulcanized, and a wide layer of white aluminum sulfate grains with poor conductive function and blocking the gap of the plate will be produced on the surface. The batteries used in the car are lead-acid batteries, if they cannot be charged, it is recommended to replace them in time.

The function of the battery is: 1. When starting the engine, it provides starting current to the starter; 2. When the generator is overloaded, it can assist the generator to supply power to the electrical equipment; 3. When the engine is at idle speed, supply power to electrical equipment; 4. It can protect the electrical appliances of the car.

Replacing a new battery can be solved, 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 consumption of battery power, for a long time will definitely aggravate the attenuation of the battery, when the battery does not store power, it is not true, in general, when the car is parked, we must ensure that the electronic equipment has been turned off.

How to charge the car battery when it is dead?

The car battery will also lose about 1% of the electricity every day without connecting any electrical components and without any load, which is the self-discharge rate of the car battery. Generally, the battery of the car will run out of power for about two months, and the battery will be out of power, which will affect the start of the car and the use of on-board equipment.

If the battery is out of power and the car cannot start, you can use the charger to charge, or you can choose to skip the battery for charging. Interconnect the battery electrodes of the two cars with charging cables, and then start the other car so that its engine idles and idles. Then try to start your car, if the battery is out of power, the car should start up quickly, and then the generator will charge the battery.

When it comes to car generator charging, when the car battery is low but the car can still be started, you can also rely on the generator to charge the car while the car is running. Under the hood, there is a part connected by a plurality of belts is the generator of the car, after the car starts, with the operation of the engine, the generator is driven to work, and the current flows through the vehicle voltage regulator transformer, part of which will be provided to the vehicle electrical appliances, and the excess part will charge the battery.
