Why does the charger heat up when charging

The power adapter converts the alternating current into direct current and adjusts the voltage to the specified voltage and then outputs it to the notebook charging module, the battery charging module will control the connection between the adapter and the battery according to the charging ratio set by the computer, if the battery power ratio is not reached, the battery will be charged, and a certain amount of power consumption will be generated in this process, so heat will be generated, which is a normal situation. If the overheating affects the use, it is recommended to go to the service center for testing.

When the charger is working, it provides DC charging for the mobile phone, and some energy will be lost in the process of AC to DC, and this energy will be emitted in the form of heat, so it is normal for the charger temperature to rise.

If the charger is severely hot and your hands are obviously hot, stop charging, back up your personal data (WeChat QQ and other apps need to be backed up separately), and bring your phone, charger, data cable, and relevant purchase voucher to a nearby Huawei customer service center for testing.

If you use a vivo mobile phone, when the charger is working, DC charging is provided for the mobile phone, and part of the energy will be lost in the process of converting AC to DC, which will be emitted in the form of heat, so you can feel the temperature by touching the charger, which is a common heating phenomenon, and you can refer to the following treatment methods when charging:

1. Use the standard charger and data cable for charging.

The standard charger has been rigorously tested to ensure both stable charging speed and safe use, so it is recommended to use the standard charger and data cable.

2. Do not let objects cover the surface of the charger.

Please do not let objects (such as: quilts, pillows, etc.) cover the surface of the charger, or paste stickers on the surface of the charger, which will affect the heat dissipation of the charger when charging.

3. Service center testing.

If the charger is more seriously heated, please stop charging, bring your mobile phone, charger set and purchase voucher to the vivo customer service center for testing, pay attention to WeChat *** "vivo" or "vivo customer service" to inquire about the address of the service center**, it is recommended to contact before going to ensure that there is a staff reception before going over, so as to avoid delaying the precious time to run in vain.

What's the deal with the charger heating up?

First of all, the degree of hotness of the charger is mainly related to the current intensity of the charger's output; Now we generally use 2A fast charging, and the difference between the temperature when charging and the non-working time is about 5°, so if you use a constant voltage flash charging charger, then the hotness must be more serious than the 2A fast charge.

Secondly, the high temperature of the charger also has a lot to do with the components of the charger, if the specifications of the switch tube used in the charger are not high, then the current will pass through, and the heat will be greater.

There is also a problem with the volume of the charger, in order to be easy to carry, the charger will pursue to make the product smaller, then the heat dissipation performance will be worse, and the requirements for electronic components will be higher.

Of course, copycat products are more likely to cause abnormal temperature increases; The stability of the output voltage of the cottage charger itself is not as good as the original charger, which will cause serious problems with the charger heating, so we should try to use the original mobile phone charger.

So what problems do we want to avoid when using the charger?

When we use the charger, we should avoid direct sunlight, keep away from heat sources, the charger shell and bottom should not cover items, and should be well ventilated.

When charging with the charger, the elderly and children should be avoided from touching the charger.

The metal contacts of the charger are live when unplugging and unplugging, and it is strictly forbidden to touch them with your hands, or contact the two contacts with conductive objects.

When charging, if the charger shell is hot (about 50) or smells smoking, it should be unplugged immediately, stop charging, and should not be used again.

Some mobile phones are not able to support charging while playing, so while charging, playing with the mobile phone, there will be a hot mobile phone, the charging plug or charging cable of the mobile phone problem, it is recommended to check whether the charging plug or charging cable is damaged or poor contact in time, if it is damaged, it needs to be replaced in time!

It is normal for an electric car's charger to get hot while charging.

It is normal for the charger of an electric vehicle to get hot while charging, but it is important to pay attention when it continues to heat up. Mainly because the current flow will flow when charging, and the charger heating is a common phenomenon. However, the heating of the charger is generally caused by the poor quality of the charger, common faults, incorrect chargers, crooked charging, aging of the battery, etc., which should not be taken lightly.

Aging of the battery. As the battery ages, only a small fraction of the charger's current goes to the battery. Although we didn't notice the difference from the outside, the temperature of the charger and the battery is not the same.

or ultra-high temperature, you must unplug the switching power supply immediately, find the cause, and then charge after solving the problem.

Charging method is wrong. When charging, never use it in rainy days or strong sunlight. The charger and battery are very susceptible to getting hot, and in severe cases, the battery can happen**.

What's the deal with the charger heating up?

Why is the pot hot when you cook?

The inside of the charger is hot.

This is normal.

Charger with large case.

The internal board is also large.

The heat dissipation would be better.
