1. The charger is faulty

When the charger fails, it is usually because the internal components fall off or are damaged, which will cause the charger to fail to jump the light normally, or even fail to charge normally. In this case, the charger should be replaced in time, because it is more troublesome to repair, and it is easy to cause damage to the battery and even cause a fire.

2. The battery has a water loss fault

The overcharge of the lead-acid battery will cause the battery to lose water, resulting in the charger showing a red light all the time, the solution to this situation is to add some replenishment to the charger appropriately, be sure to find a professional maintenance personnel to add, do not replace it yourself.

3. There is a short circuit in one of the batteries of the battery pack

If one of the small batteries in the battery pack has a short circuit, the charger will not function properly while the EV is charging. The user can use the multimeter to detect first, and the lowest voltage display is the short-circuit battery, which can be solved by going to the maintenance station to replace it with a new one.

Charger maintenance tips:

1. Waterproof and moisture-proof. As a sub-product, accidental water ingress or exposure to humid air when not in use for a long time will cause varying degrees of corrosion or oxidation to the electronic components inside.

2. Drop-proof and shockproof. A mobile phone charger is actually a fragile component, and the internal components cannot withstand a beating. In particular, it is necessary to prevent accidental landing during use. Do not throw, knock or shake the charger.

Reasons why the charging lights are always green, and the charger is always green: 1The charger adapter or fuse is damaged, resulting in the charging light being green all the time and the charge cannot be charged.

2.If the charging light is always green, the first aspect to consider is whether the charger is faulty, which usually manifests as damage to the converter or insurance. If the converter has been damaged, then the charger will not be able to convert and charge normally, and this will cause the slag Lushen charging to be green and unable to charge.

If the insurance is damaged, it will be directly manifested as a failure to charge. In this regard, the correct solution is to replace the converter or insurance, but if it still can't be solved, you can only choose to change to a new charger. A small battery in the battery pack is faulty, resulting in the charging light being green and not charging.

3.Secondly, the aspect that needs to be considered is whether the battery is faulty, which is generally manifested as an open circuit fault of a small battery in the battery pack. And when this is charged, the charger will always show that the green light is not charged.

The headlamp charger keeps flashing red to indicate that it is charging. It is normal for the charger to keep flashing red light when charging, and the charging status indicator indicates that it is charging, and when it is fully charged, the charging status indicator will stop flashing or turn green;

If the power is sufficient, then it is a problem with the charger, the red light keeps on, and the headlamp power is also insufficient, then it may be caused by a problem with the internal battery of the headlamp itself.

Headlamp is an indispensable and important equipment in outdoor activities, such as night hiking, night camping, the first headlamp uses power-saving technology, such as LED cold light technology, and the innovation of lamp cup material on high-end headlamps, which are incomparable to civilian flashlights.

1. The internal components of the charger fall off, are damaged or malfunction, if this situation occurs after the charger is dropped, it can be determined that it is a problem with the charger, such as the converter is damaged, resulting in the charger being unable to jump the light and charge normally. 2. Battery polarization, water loss failure or short circuit of a group of batteries in the battery pack, and the charging voltage does not reach the limited voltage value, this requires finding a professional to add replenishment to the battery, re-disassemble the battery, or replace the new battery. Users can use a multimeter for testing, of course, it is generally not an electrical maintenance family, few people have this testing instrument, it is best to go to the maintenance site, let the professional master test and repair.

3. The model parameters of the charger are wrong, and the positive and negative contact wires of the charger are wrong, resulting in the charger burning out or short circuit. If the charger still keeps showing a red light, then it is a problem with the battery. Generally speaking, batteries of different brands cannot be mixed, and old and new batteries cannot be mixed.

4. Observe whether the battery is bulging or cracked, in this case, the battery should be replaced, and the total voltage and the voltage of a single battery should be measured with a universal meter. When a good battery is fully charged, it can only reach about 14V. If the voltage value is obviously too low, then there must be a problem with the battery, and it is recommended to replace the entire set of batteries.

Otherwise, it can be judged that it is still a problem with the charger.

It should be that the charger is faulty, after the common charger current limiting resistor burns out, the charger will appear to flash the traffic light alternately and the charger fan will not rotate when charging.

It should be noted that when replacing the charger, the positive and negative poles of the output line of the new charger and the old charger must be the same.

There are several reasons why the charger flashes red and green together.

1. The red light of the charger is on but does not flash, and the red light is still on after charging overnight, which means that the charger is energized. But the battery is not charging, there are two reasons, one is the battery charging plug is broken, the line is faulty and other physical reasons. The other is that the battery itself has been vulcanized, and the increase in internal resistance causes the electric vehicle battery to be charged, or it is fed.

2. The red light of the charger keeps flashing, and the red light does not flash after charging for a long time, but the green light does not light up. In this case, either the charger green light is broken, or the battery is overcharged and damaged, and at this moment you need to find a charger of the same model to verify it again to determine which one is broken.

3. The charger flashes red light and green light flashes, which means that the battery has not been used for a period of time, and the battery has electricity, which may be virtual electricity. At this point, you just have to wait for a while, and the green light will go out when the current comes up.

4. The green light of the charger has been on, and the green light has always indicated that the charging has sensed the current coming from the battery, but it has not been charged, and there are the following 3 situations: the first is that the charger itself has a circuit problem, resulting in an error signal received internally to turn on the green light, and the second is that the battery feed capacity becomes smaller but there is some weak current passing through, and the charger is "deceived" to cause it to turn on the green light.

It is normal for the charger to keep flashing red when charging, because this is the charging status indicator, which means that it is charging, and when it is fully charged, the charging status indicator will stop flashing or turn green.

How it works: The charging indicator of the charger is only caused by the detection voltage being too low. When charging, the charging current is relatively large, the red light is on, the green light will turn after charging for 10 seconds, and the voltage will turn green when the voltage rises to the detection voltage.

This means that the charger itself has a circuit to detect the voltage level inside, as long as it is modified on the original basis, it can meet your requirements.

1: Change the sampling resistance of the post-stage of the switching power supply, and increase the secondary voltage of the charger by 1V to the left and the right.

2: Change the charging current sampling resistance to make it smaller, so that its voltage is lower can also have an effect.

The phone can't turn on the red light may be due to the following reasons:

1.Low battery: If your phone's battery is too low, it may prevent your phone from turning on properly. At this point, you can connect your phone to the charger to charge it, wait for a while, and then try to turn it on.

2.System failure: If your phone's system is malfunctioning, it may cause your phone to not turn on properly. At this point, you can try to enter your phone's recovery mode for system repair or factory reset.

3.Hardware failure: If your phone's hardware fails, such as a damaged battery or motherboard, it may cause your phone to fail to turn on properly.

The phone automatically shuts down, and the charging indicator keeps turning on the red light but can't turn on the solution:

1.It may be that the battery is out of power, you can try to connect the computer with a data cable to charge for 30 minutes, and then restart to see if it can be turned on normally.

2.It may be an abnormal boot, you can try to force restart, press and hold the boot button for about 10 seconds to turn on and try to see if the phone can start successfully.

3.If none of the above methods work, you can try to replace the battery and rule out whether the battery is faulty.

You can try to press and hold the volume up, volume down, and shutdown buttons in the shutdown state, and let go when the boot screen appears, and you can enter recovery. Go to Recovery Chinese Clear Data to Empty All Data).
