What should I do if the battery car charger does not turn light?

The causes and workarounds are as follows:

The battery is aging and cannot be charged; A new battery is required.

The charger is not a smart charger, and it does not have the function that the normal charging is red and the indicator light turns yellow-green after sufficient charge;

The output line of the charger is soldered, disconnected, or the plug and socket are not in good contact. Tests are used to find faults and troubleshoot them.

There are the following points that need special attention when using battery car batteries:

Do not buy retrofit batteries.

Charge within the specified time according to the product instruction manual.

The voltage of the pumping unit and the voltage of the battery are matched.

Do not charge the battery at home.

It may be that the charger is broken, or it may be that the battery is broken, and the battery capacity becomes low, resulting in the failure to meet the standard of lighting up.

How to solve the problem that the electric vehicle charger does not change the light is inseparable from these five reasons, and I have learned!

The first is that it's been aging for a long time. The second is broken, the third is not a smart charger, and the fourth is broken.

The battery is aging and cannot be charged; A new battery is required.

It may be that the battery is not working.

The battery car charger does not change the light (for example, it has always been yellow-green) has the following possibilities:

1. The battery is aging and cannot be charged; A new battery is required.

2. The charger is not a smart charger, and there is no function that the normal charging is red, and the indicator light turns yellow-green after sufficient charging;

3. The output line of the charger is soldered, disconnected, or the plug and socket are not in good contact. Tests are used to find faults and troubleshoot them.

This may be a problem with the charger detection circuit of the electric vehicle, the detection is not accurate, this problem will occur, you can change a charger to try it.

There may also be a problem with the battery, generally a battery that has been used for a long time, it should be almost life, or it is about to be damaged due to a long-term battery loss.

So while charging, you can touch the case of the battery with your hands. When the battery arrives at such a time, the battery shell will obviously feel hot when it is recharged.

Once the battery has the above problems, it should be replaced in time after testing, otherwise it may be dangerous.

The battery is faulty and cannot be charged normally. The line has poor contact. The charger is faulty or the indicator itself does not have a discoloration function.

When the EV charger is fully charged, first check whether there is a problem with the charger connector and whether the circuit board chip of the charger is abnormal.

The battery is aging. Or maybe the charger itself is faulty.

There is a problem with the automatic power off. At this time, it depends on the time to recharge. Otherwise, the battery will easily be flushed.

The charging of the electric car charger remains the same, and the light has been charging, in this case, it means that there is a problem with the charger of the electric vehicle, and he has not been charging, but his indicator light. I cannot be reminded. Charging is complete.

Reasons and solutions for the green light of the electric vehicle charger:

1. When the plug of the electric vehicle charger is faulty, when we are charging, we find that the charger does not turn green, we need to unplug it immediately, and then see if the plug is burned, because when the charging plug is burned, the charger will not change the green light.

2. The internal parts of the charger are faulty, so that the electric vehicle charger does not change the green light. If the internal components of the electric vehicle charger fall off, the parameters of the charger will be inaccurate, which will directly cause the electric vehicle to fail to charge normally, resulting in the situation that the electric vehicle does not change the light when charging.

3. If there is a problem with the circuit of the charger, when the internal circuit of the electric vehicle charger fails, even if the electric vehicle is fully charged, the light will not change. So at this time, we need to check the circuit of the charger.

Notes:

The battery car charger can not be mixed, because the charging voltage and battery of different chargers of electric vehicles are different, so the charging voltage and current of the electric vehicle charger must be the same as the original car to be used. Chargers with different charging voltages and currents can be mixed to risk damaging the EV battery.

In addition, it is also necessary to pay attention to the original charger of the electric vehicle when charging. Because if the charging voltage is not matched, it will cause a lot of damage to the battery, which will cause other problems to occur.

1. Electric vehicle charger failure:Electric vehicle charger Electric vehicle charger failure, which is generally manifested as internal components falling off or damaged, which will cause the charger to fail to jump normally, or even unable to charge, causing the charger to display a red light all the time. In this case, the only option is to replace the charger with a new one, rather than repairing it, because the charger is more troublesome to repair and it is more likely to cause problems again and cause the battery to overcharge.

In addition, it is important to note that replacing a new charger requires the consistency of matching voltage and current.

2. The charger current is too small, and the charging time is longThe battery cannot be effectively charged within the estimated time, causing the charger to not rotate, etc. The charging environment temperature is too high, resulting in the charging voltage of the battery end not reaching the limit voltage value, and the charging current is always maintained at a large value, which cannot be reduced to the inflection point current value, resulting in the charger not turning.

Precautions for EV charging.

No matter how far the distance is, it should be charged immediately after use, and charged as it is discharged, do not charge it until the power is completely used up, if the car is not used for a long time, it is also necessary to ensure that the battery is replenished once a month, which can not only protect the battery, but also extend its service life.

When the charging indicator turns from red to green, it means that the battery is fully charged, and the continuous charging time cannot exceed 12 hours, otherwise it is easy to cause deformation and damage to the battery. After driving long distances in summer, wait for half an hour before charging, do not charge outdoors in the sun, and it is best to charge indoors in winter.

The above content refers to People's Daily Online-Electric Vehicle Charging, pay attention to the "four don'ts".

The battery capacity fails, and the charge is always undercharged, so it is always displayed in the charge; Or the charging protection circuit of the charger is broken and loses its protection function.

You're not right, it's supposed to be a red light when charging, and a green light when it's full. A green light indicates that the battery is full or uncharged. You can see what the light is on when the charger is not charging, and when it is plugged into the power strip.

Cause of failure: 1. Battery failure. When the final voltage of the battery is lower than the rated final voltage, the charger always detects that it is not fully charged, so the charging does not stop.

2. The charger is faulty. When the actual output voltage of the charger is higher than the rated output voltage, there will also be a non-stop charging failure.

What happens when the electric car charger is charged and the second one remains the same?

1.The converter or fuse of the charger is damaged First check whether the charger is fault-free, the general charger damage is mainly the converter and the fuse are damaged, if the converter is damaged, it can not be charged directly, the correct way is to replace the converter or insurance. 2.

Battery failure Check whether the battery is obstructed, you can use a multimeter to check whether the battery is faulty, find the battery and repair it, if it can't be repaired, replace the battery. 3.Check whether the connecting cable has fallen off and connected the sail Jane Check whether the connecting line has fallen off and connected around the battery, which is generally manifested as the loose interface or the missing line is corroded, if this situation occurs, it needs to be replaced and wired again.

It may be that the charger is damaged, so it is recommended to use another charger to give it a try.

If the charger is damaged or mismatched, it may be that the charger is damaged, and it is recommended to use another charger to give it a try.

1. The voltage control of electrical appliances is too inferior, some cheap chargers, and some chips are not good.

2. The battery loses too much water and burns, the oxygen circulation is smooth, the battery is heated, and the charging current is increased at the same time, and the current can not drop below the current of the turning light, and it is always in the high-voltage stage. Even the current does not drop but rises, forming a vicious circle and thermal runaway.

3.The charger charges the battery, and it will show a green light as soon as the power is turned on, which may be a short block for the battery, but there will also be two other phenomena, one is that the charger has been damaged, and in some cases the charger is damaged and there is no display when the charger indicator is turned on, but some are directly displayed with a green light; Another kind of situation is caused by line problems, such as virtual connection of the line, or the circuit cannot form a circuit when the charger is connected to the power supply.

The charging of electric vehicles does not change the green light, it may be a problem with the battery, and it may be the reason for the charger.

If it is the cause of the battery, it is divided into several types:

1. The self-discharge of the battery is large, and its self-discharge current is larger than the current of the charger.

2. The amount of battery electrolyte is insufficient.

Only one or more batteries are disconnected (sudden drop in voltage).

When choosing a charger, you must see whether the charger is fully charged and truly automatically powered off, otherwise it will be easy to charge the battery after a long time.

If it is a problem with the battery, then it is necessary to consider replacing a new set of plates, or repairing it, as long as it is not a serious plate deformation, it can generally be repaired to 80-90% of the original capacity.

1. Charge as soon as you stop the car.

Many users will charge the electric vehicle as soon as they ride home, but they don't know that this charging method will accelerate the speed of battery water loss. The main reason for this is that the electric vehicle will emit a lot of heat when it is running, which will heat up the battery, which will cause the battery to be in a high temperature state when it is just stopped.

If it is charged at this time, the battery will continue to heat up one after another, resulting in water loss and reduced battery life. Therefore, users should not charge the car as soon as it is stopped, but should leave the car for half an hour and wait for the battery to cool down before charging.

2. The charging time is more than 12 hours.

Some users also charge their EVs overnight or all day, often for more than 12 hours. Although today's chargers have a certain amount of charging protection, in fact, after the battery is fully charged, there is still a weak current that will continue to float the battery.

Once the floating charge time is too long, it will also cause certain damage to the battery, thereby shortening the battery life. Therefore, the charging time of electric vehicles should not be too long, but should be controlled within 8 hours as much as possible.

It is possible that the battery is broken, or it may be the charger.

The reasons why the EV charger does not light up are mismatch between the battery and the charger, quality problems, blown out of the charger fuse, burned out internal capacitors of the charger, and so on.

1. The battery and charger do not match

A mismatched charger can cause the battery to move heat from the power supply while charging, resulting in hot heat.

2. Quality problems

When charging the battery of an electric vehicle, a large amount of hydrogen needs to be volatilized, but the new battery generally does not have this kind of hot condition, because it is processed by the manufacturer, and the temperature is constant.

3. The charger fuse is burned out.

The charger of the electric vehicle has been used for a long time, which may cause the fuse inside to burn out, once it burns out, the charger has no way to charge the battery normally, you can go to the repair shop for corresponding inspection.

4. The internal capacitor of the charger is burned out.

After using it for a long time, the capacitor may burn out, so it cannot be charged, and the indicator light will not be lit, so you need to go to the repair shop in time to find a maintenance master for testing or replace the charger with a new one.

Notes:

Constant current charging of electric vehicle charger means that when the battery is charged, the method of segmented constant current is used for charging, and the current is achieved by adjusting the charging chain. Its main feature is that the charging method has great adaptability, and the charging current can be selected and adjusted arbitrarily. As a result, batteries can be charged in a variety of situations and states.

It is particularly suitable for charging batteries that are connected in series by many cells in series in a long period of time with a low current, and is good for charging batteries with slower capacity recovery.

However, because the charging current of this charging method is too small at the beginning stage, and the charging current is too large again in the late stage of charging, so the whole charging process is long, the precipitation gas is more, the impact on the plate is large, the energy consumption is high, the efficiency is low (not more than 65), and the whole charging process must be supervised by a special person. Therefore, it is only used for the initial charging of the battery and when it is necessary to desulfurize and recharge quietly and coarsely with a small current for a long time.

1. The charger and the battery do not match, resulting in the electric vehicle charging does not jump the green light mixed charger, which will lead to the mismatch between the charger and the battery, causing the electric vehicle battery to overcharge, or even the situation that the charging does not jump the green light. For such a problem, the user needs to make a special charger for the special car, which can solve such a problem.

2. If a single battery of the battery pack fails, resulting in the failure of the single battery of the electric vehicle battery pack without jumping the green light for electric vehicle charging, then the charger will not jump the light during the charging process of the electric vehicle. For such problems, the general practice is to rematch the battery or replace it with a new battery, and the problem can be solved.

3. The internal components of the charger fall off, so that the charging status is not displayed abnormally, and the long-term shaking with the car will cause the internal components of the charger to fall off, resulting in inaccurate charger parameters and abnormal display of the charging status. For such a problem, the general solution is not to carry a charger with the car.
