The root cause of the high power wireless charging problem is that the high power wireless charging on the market now relies on high current to charge, but this situation is tantamount to increasing the resistance, thereby increasing its temperature, so it is necessary to use high heat absorption and high heat dissipation materials as the outer packaging, in addition, it is necessary to reduce the resistance accordingly. This will fundamentally reduce the fever.
In addition, the heat dissipation design of the phone will also shadowRing its temperature during wireless charging. If the heat dissipation system of the phone is not efficient enough, or the heat dissipation port is blocked, then the phone is more likely to get hot during the charging process. At the same time, the use of wireless charging for a long time or charging at high power will also exacerbate the heat of the phone. Finally, the use environment is also a factor that cannot be ignored.
Millet wireless charging mainly relies on the electromagnetic coil scheme for energy transfer, if there are too many obstacles between the coils, it will not only affect the charging power, but also lead to the aggravation of the heating problem, so it is also recommended that you put the heavy mobile phone when wireless chargingIt is better to take off the shell and let the phone "lie naked" on the wireless charging seat.
The battery caused by too much current is hot, if the battery is very hot, suspend the use, otherwise there will be a risk of explosion, the high current is strictly affecting the battery, but not too high temperature, the battery life is not affected. Wireless charging will not damage the mobile phone hardware, unless the power is too high, wireless charging will not affect the life, the heat is normal when the direct charge will also heat, but overheating is not good heat dissipation or wireless charging equipment has a problem.
Generally the use of metal heat dissipation can reduce the heat transfer to the mobile phone, thusPower, such as the standard charging head of the old iPad is this specification, if you have a charger, you can use the combination of the original charger data line to directly use the ipad charger.
1, as far as possible to improve your wireless charging conversion efficiency, optimize the control algorithm to enhance your heat dissipation effect, add heat sink or air cooling. The general wireless charging scheme will have a temperature control circuit and NTC thermistor, this function is mainly to prevent the circuit from generating too much heat in the process of working, burned components, etc.
2, wireless charging, mobile phone fever is a normal phenomenon, but overheating may be dangerous. Wireless charging technology uses the principle of magnetic coupling to transfer power between the transmitter and the receiver. In this process, part of the electrical energy will be converted into heat, causing the phone and charger to heat up. This is a common phenomenon of wireless charging and does not mean there is a danger.
3, the answer is: there will be harm, shorten life. We all know the characteristics of lithium batteries, lithium battery operating temperature is generally 0-40 ° C, if long-term in a high temperature state of 60 ° C, it will damage the battery.In fact, there are so many fundamental reasons for mobile phone wireless charging fever, know the reason, you can choose a more suitable product, rest assured that the bold enjoyment of wireless charging: the choice of solution.
1, it is recommended that you use the standard charger to charge the use of other third-party chargers, although you can also charge the phone, but due to differences in charging specifications or charging protocols, it may cause problems such as heating.
2, generally use metal heat dissipationThe method can reduce the heat transmission to the mobile phone, thus affecting the charging power of the mobile phone, and will inevitably increase the metal block on the circuit board or coil, which is similar to the notebook CPU plus copper tube heat dissipation. Or increase the active fan heat dissipation, and use the fan to cool the motherboard and coil, which can achieve the delay power reduction time.
3, x is Apple X, the reason for x wireless charging heat is the wrong charging posture, the solution: use the correct charging posture to charge. The iPhoneX (pronounced "iPhoneten" in English) was released at 1 am Beijing time on September 13, 2017Check out Apple's 10th anniversary special edition, unveiled at Apple's 2017 Fall Product Launch event at the Steve Jobs Theater at ApplePark's new headquarters.
4, does the subject want to ask "k60 wireless charging heat how to do"? Power off and use wired charging. You can try to power off and charge the phone without consuming energy. The energy loss of wireless charging technology is larger than that of wired, and the energy loss will cause heat, so wired chargers can be used.
5, if it is too hot, you can try to shut down the charge, or directly use the charger to charge the battery. The phone runs large for a long timeThe software causes the parts of the phone to be in a high strength state, which causes the phone to burn; Such as playing games for a long time, watching videos for a long time, etc. At this time, you can suspend the operation of large software and wait for the phone to return to normal temperature before continuing to run the software.
Wireless charging mainly relies on the electromagnetic coil scheme for energy transfer, if there are too many obstacles between the coils, it will not only affect the charging power, but also lead to the aggravation of the heating problem, so this is also recommendedWhen children's shoes are wireless charging, take off the heavy mobile phone case, and let the mobile phone "naked" on the wireless charging seat is better.
Personal think and charging equipment is related, millet 80W wireless charging base built-in cooling fan, charging the default open speed wireless charging mode (feel the noise can be manually closed), we can hear the fan in the process of charging "buzz" sound, hand near the bottom of the wireless charging base, can also feel the cool wind blowing out of the fan. I hope I can help you.
Nothing generally there is heat when charging the mobile phone at normal room temperature, the heat does not exceed60℃ is a normal phenomenon, it will not damage the battery.
If the noise is large, it may be the charger problem, you can change the charger to try charging. If the noise comes from the mobile phone, it may be a short circuit or leakage of the internal circuit of the mobile phone, or it may be a fault of the tail plug, and it needs to contact Xiaomi's after-sales service to repair the mobile phone to solve it.
It is usually connected to the vehicle's power system through the vehicle's cigarette lighter socket or USB interface, and the car charger has portability and flexibility, and can charge the device during driving or when parking, which is convenient for the user to keep the electronic device in the carPlenty of power. Although today's cars have developed a lot of their own charging methods, such as their own charging brackets, as well as wireless charging stations, etc., the car charger is still a necessary tool for many old drivers.
