How to fix an electric car charger that has been a green light? 20

1. Try a charger of the same type to see if it is the reason for the charger or the battery.

2. The problem of the charger is directly replaced with the charger, from the perspective of economy and practical convenience, the charger is not necessary to repair, that is, the professional maintenance personnel repair, and it cannot be guaranteed to be used normally after repair.

3. If there is less water in the battery, it will also produce the phenomenon that the light is always green, add some distilled water to the battery. If the battery is used for a long time, the only way to replace the battery is to replace it, and the battery warranty is only one year. ‍

The electric vehicle charger has always been a green light, which may be caused by the following circumstances: 1. Voltage detection circuit failure; 2. The power output wire is broken. The former needs to specifically detect the relevant circuit, and the latter only needs to use a multimeter to measure whether the output plug has a normal voltage.

It is estimated that there is a problem with the current detection circuit or detection resistor of the rotating lamp, and the specific fault point can only be judged by looking at the circuit.

It depends on what your charger looks like. Green is a state of charge or saturation. If it is in charge all the time, there is a problem with the battery. If the green color is unloaded, the battery line is faulty.

The lack of water in the battery is also a green light.

Turn on the charger and look at the fuse, the old-fashioned charger has two fuses, one for input and one for output. Find out the broken ones and solder them with jumpers.

The converter of the charger is damaged and cannot be converted and charged, replace the resistor of the charging attitude bridge.

When the power is found to be lower than about 30% during use, it should be charged in time. Long-term deep discharge (riding to the point where the system is forced to power off) or too shallow discharge (only riding 1 2km) will affect battery performance. Charge the battery when 70% of the battery is used up, and the battery performance is the best.

After the battery is used up, it should be fully charged in time, and the charger will show a green light to indicate that it is fully charged. Storing the battery for a long time or starting to use the battery before the battery is fully charged will affect the performance of the battery, and it is especially effective to use the battery for 3 hours after the charger turns green.

EV chargers have always been the green light because:

1. The converter of the charger is damaged and cannot be converted and charged, replace the charger resistor.

2. When the battery is opened, it is soldered and checked with a multimeter.

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.

Pay attention to the use of batteries and chargers.

1. When riding on bridges, climbing mountains, headwinds or riding with people, manpower should be supplemented. This avoids the effects of high currents on the battery and increases the charging range. Sun replied.

2. When electric vehicles start, they need to be ridden by manpower first, and then use electric drive after a certain speed. This avoids the impact of high currents on the battery, motor and drive, increases the range and extends the service life.

Q dear--- battery car pie vertical charger has been on the green light; 1. The green light is a sign that the battery is full, if the battery is out of power, the green light may not be available after plugging in the charger. 2.

Hello, I'm helping you sort out the answers to your questions, please wait a moment

Hello, a hail argument button turns on the green light, indicating that the battery is not short of power or the line between the charger and the battery is virtually connected or broken, as long as the charger has no current output, it is the stove with a green light. Yuan Qiao.

Questions. What's going on with the charger output plug and the two wires also have power?

If there is power in the plug and the line is not falsely connected, check whether the battery is damaged or the battery connection line is false.

Questions. The battery is also set to the river to reduce the amount that has been filled with another charge and some feeding.

Another charger can be charged, but there is a problem with this charger, the line is good, and the internal control board of the charger is broken.

Questions. There is no problem with the battery, I have charged it with another one by one, I bought a new charger and that's it, what is the problem with which department? Please indicate.

Now that the battery and power supply have been eliminated, the problem is that the original charger output line is virtually connected, or the charger itself is faulty.

Questions. What exactly are the areas that are problematic?

If the output cable is damaged, or there is a problem with the charger's internal circuit board, these two possibilities are.

The first aspect to consider is whether the charger is faulty, which is generally manifested as converter or insurance damage. If the converter has been damaged, then the charger can not be converted and charged normally, and this will lead to the electric vehicle charging has been green light charging can not be charged, 2, the battery pack a small battery failure, resulting in the electric vehicle charging has been green light to see if it can be repaired, 3, the battery wire end or battery plug off check it, I hope mine will help you.

Here's how to repair an EV charger that keeps the green light:

1. Check the socket and wires.

Electric vehicles will generally display a red light when charging, and a green light will not be displayed until it is fully charged. If the green light keeps showing the section, it may be a fault of the line, or the socket is not plugged in properly. At this time, you can check the wire to see if there is any damage; Or check that the socket is plugged in.

2. Replace the resistor.

If the charger keeps showing a green light, it is very likely that the charger's converter is broken, resulting in the inability to convert and charge. At this time, the charger should be disassembled and the resistor replaced.

3. Replace the charger.

Electric vehicles rarely have such failures, if the Wild Reputation charger keeps showing a green light, it may be because of the charger's internal wiring problems, such as broken fuses, poor line contact. When encountering this kind of problem, it is difficult for us to solve the ridge disassembly by ourselves, and we can replace it with a new charger.

4. Find a master for maintenance.

If you feel that there is no need to change the charger, you can find a professional master to repair it.

Here's why:

1. The charger indicator is problematic. The charger of the electric vehicle is made of two kinds of indicators, red and green, when fully charged, it will turn on the green light, and when it is not full, it will turn on the red light, if the charging indicator is damaged, then it may always be green or not on.

2. Other components of the charger are damaged. The charger contains different components, once damaged, it may cause the charger to keep the green light and not charge the power, the more common is that the converter has a problem and cannot be converted normally, and the fuse is burned out for a long time.

3. Battery failure. The battery is easy to age after a long period of use, or there are problems such as deformation and bulging, which will also cause the problem that the charger lights up green and cannot be charged.

4. Line failure. The more common line fault is that a certain part of the line is damaged or the position of the interface is falsely connected, resulting in the charger always turning on the green light, and there is no way to charge the battery normally.

A green light means that it is fully charged, or not charged. If you are chartering a car, then it is very likely that the line from the charging port of the car to the battery is broken.

That's because the battery of your electric car is broken, and my car has had such a problem.

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.

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

4. The power supply will let the wild line fall off from the battery socket and the battery socket of the forest shout, and the contact will be poor, and it will be checked and replaced.

Precautions should be taken when using batteries and chargers.

1. When riding on the bridge, climbing a hill, headwinding or taking people to ride, it should be supplemented by manpower riding. In this way, the impact of high current on the battery is avoided and the cruising range is increased.

2. When the electric vehicle just starts, it is necessary to ride by manpower first, and then use electric drive after a certain speed. This avoids high currents on the battery, motor, and drive.

to increase the cruising range and extend the service life.

The electric vehicle charger is plugged in to the power is a green light, most likely because the wire between the electric vehicle battery and the controller is burned out, or the contact is poor, the solution is to repair this strand of wire.

What to pay attention to when charging:

It is more appropriate to charge the new battery for about 6 hours. The specific charging time of a single charge of the first grip source is not very clear to everyone. Most people refer to the charging time of their mobile phones, but the battery of an electric car is completely different from that of a mobile phone.

Most of the batteries used in electric vehicles are lead-acid batteries, which have never been charged and discharged before leaving the factory.

Therefore, it is most appropriate to ensure that the new EV battery is charged for 6 hours so that the EV battery undergoes a relatively complete chemical reaction. As for charging for 8 hours, most of them can be charged a little more during the later application process.

The things you need to pay attention to when buying a car are as follows:

1. Confirm the purchasing ability

Determine the purchasing power, after buying a car does not affect the overall quality of life of the family, generally according to the average income of the family in the past three years, generally take out 20% of the family for three years, but Botan is not more than 10% of the value of the family's fixed assets.

2. Concerns:

The most important thing for a family car is safety, followed by affordability, because the safety of the car carries the life of a family, so safety is the top priority.

3. On-site confirmation:

According to the above two steps, basically determine the several models to buy, and go to the 4S store to confirm on the spot, including Duan Yinzhi test drive, inquiry, loan situation, maintenance and other related information.

Keeping the green light is either the charger is broken, or the battery is not really connected to the charger, such as not plugging in properly or the wire is broken.

I also have a charge.

The copy, the charging is normal, and the green light is on. As soon as it is charged, it will turn on the green light. It's full, and it's still green.

There is no problem with the resistance and capacitor, and it is suspected that there is a problem with the eight-pin chip integrated circuit, there is no handwriting on it, and I don't know what model. Depressed. Experts, please give me advice.

Thank you!!

Just go and repair the electric car, my previous charger is like this, or buy a new one.

The charger is malfunctioning.

If you will use a multimeter, first use the connection file to see if the output line is broken, and the possibility of disconnection accounts for about 40% of the charger failure.

If you really don't understand, ask a car mechanic to take a look, or just buy a new one.

1. The converter of the charger is damaged, and it cannot be changed and charged internally, and the resistor of the capacitive charger can be replaced.

2. The battery is welded and checked with a multimeter.

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

4. The power cord and the battery socket fall off and have poor contactCheck for replacement.

It depends on what your charger looks like. Green is a state of charge or saturation. If it is in charge all the time, there is a problem with the battery. If the green color is unloaded, the battery line is faulty.

1.It is the interface between the battery and the charger BAI that is broken.

Road or virtual connection Check the inside of the battery car, 2, the DAO output line of the charger is broken or the plug is connected to the virtual Open the charger to check whether the solder joints and the line are disconnected The charger and the electric vehicle are not in good contact See if it is loose Dial it twice with a tool See if the green light turns red It's OK If there is a problem with the battery, see what the problem is, see if it's a quality problem.

You can take it apart and see if you want to cut off the power to 1, see if the light foot of the charger has fallen off

The line (virtual welding) is generally the foot of the red light 2 If there is no dao problem above, it depends on whether the line connected to the battery inside is dropped or broken (can be measured with a universal meter) 3。。。 Then see if the line on the battery in the car is dropped or broken, generally just these kinds of problems, you can try, if it still doesn't work, you are asking, make the problem clearer, so that it can be better detected.

It is the loose wire behind the output plug of the charger that is open one by one.

Turning on the green light means that the electricity has not been rushed in, you can check from the flushing hole first, and replug the flushing plug when the power is turned on to see if the light reflects, and the second step is to check whether the flushing head has electricity (the flushing power has not been sent over). The third step is to check whether the electric vehicle flush port is also available (exclude whether the flush port to the battery line is good) If these three points are all right, then there is no reason not to charge.

Battery problem, the battery is broken, the protection board protects not charging, the new charger and the old charger have the same effect, and the green light is on when there is no load.

The new charger charges the old car, the battery type may be different, the charger voltage is low, the battery voltage is high, and the green light is on;

Maybe the output of the new charger is broken, and the green light is on at no load; If the green light is not on when there is no load, it is possible that the new car is a lithium battery with a different voltage.
