If you are consulting Glory phone, handHeat is a common phenomenon when the machine is charging, especially to support fast charging, when charging, the current and voltage are larger, so the temperature will be higher than ordinary charging. To avoid serious heating of the mobile phone, you can use the following methods: It is recommended that you use the standard charger to charge.
However, I found in the process of use, although the charge is fast, but the charger becomes hot in a short time. Considering that it is normal for mobile phones to heat up while charging, because the conversion of electrical energy into heat is inevitable, especially when charging the phone at the same time, the temperature will rise.
The charger also gets hot during the normal charging process,Please use it in a well-ventilated environment, do not cover the charger with blankets, clothing or other insulating materials. When charging, the charger is charged at a high temperature. The reason for using the charger to charge heat is that when the charger is charging, the mobile phone and the charger have an energy conversion process, and the heat generated will be emitted, so there is fever when charging. Please use the phone as little as possible while charging.
Heat is a common phenomenon when charging mobile phones, especially support fast charging, super fast charging mobile phones, when charging, the current and voltage are larger, so the temperature will be higher than ordinary charging. If you are doing wireless chargingBecause there will be energy loss in the wireless transmission process, which will generate a certain amount of heat, there will be a phenomenon of heat when wireless charging, which is normal.
The mobile phone will have some heat when charging, which is normal, because in the charging process there will be a certain loss of electrical energy, this part of the electrical energy into heat will make the mobile phone and the charger to keep warm, such as the use of mobile phone temperature will be higher when charging.
There will be energy loss in the process of charging current transmission, resulting in a certain amount of heat; For mobile phones that support fast charging and super fast charging, the current and voltage are larger when charging, so the temperatureIt's hot. Why?
1, the charger heat is very hot reasons: energy conversion loss, efficiency problems, overload or overheating protection, ambient temperature and ventilation problems, equipment charging needs. Energy conversion loss: Energy conversion loss occurs when the charger converts electrical energy to the current and voltage suitable for charging the device. These losses are released in the form of heat, causing the charger to heat up.
2. If the following problems occur during charging of your Huawei mobile phone charger: The charger loses energy during voltage and current conversion, and the dissipated energy will cause the charger to heat up, which is generally chargedThe greater the flow, the greater the heat. If you are in a high ambient temperature or there are other heat sources near the charger, the temperature of the charger will also increase.
3, there may be several reasons why the mobile phone charger is hot. One possibility is that the charger itself is poorly designed, or the quality is not up to standard. If the heat dissipation performance of the charger is not good, it is easy to generate too much heat when working, resulting in very hot heat. Another possibility is that the charger output power is too large or improper use.
4, the reason for charging hair hot may be: the charger power is too large, the charger quality is poor, the charging line is askedProblems, mobile phone battery problems, etc. If the power of the charger is too large, the current will be relatively large when charging through the charger, causing the charger itself to heat up. At this time, if you touch the surface of the charger with your hand, you will feel very hot.
5, electric car charger hot reasons may have the following points: lack of electrolyte. Insufficient electrolyte will cause the resistance of the battery to increase during the charging and discharging process, generate heat, and affect the battery life. At this time, you can choose to add the electrolyte stock. The charger and battery do not match. Using a mismatched charger can cause the battery to heat up and even cause danger.Special car charger is recommended. The battery is aged or damaged.
6, the temperature is too high to accelerate the charging hair heat: when our mobile phone is charging, the power is lost in the process of conversion, and a part of the energy will be converted into heat, resulting in the charger plug hot situation. Although it is a normal phenomenon, the heat will speed up the aging of the charger. Therefore, when we use the charger to charge, try to avoid overheating of the charger.
1, Apple 18w fast chargeHeat is normal, so a large current will certainly generate heat, as long as it is not over temperature, there is no matter.
2, iphone11 with 18w fast charge is a normal phenomenon, because 18w fast charge is PD protocol, charging head output specific parameters are 9v and 2a. This parameter is compared with the Android terminal, which is the qc0 fast charge used in 13 years and 14 years, it seems that the charging power is high, but because the 9v step-down to about 4v (charging limit voltage), the step-down process will cause the mobile phone to heat up. The iPhone is a series of smart phones developed by Apple Inc., which is equipped with its iOS operating system.
3, if it is fast charge, the heat is normal for a long time, and fast charge is not suitable for long-term use. Or it has to add heat, and the volume will increase after adding heat. Generally charge the mobile phone 4000ma charging, full of heat is normal.
4, some heat is normal when the charger is charging, but if it is hot, it is not normal, one is that the charger itself current can not reach l000mA, to make the charger hot, the second is that the internal resistance of the charged battery changes can not stand the impact of 1000mA current, bringing the charger hot. There will be a certain amount of hair during the charger processHeat phenomenon, at normal room temperature, as long as it does not exceed 60 degrees Celsius is normal display will not damage the battery.
