1, you want to ask wireless charging body hot is whyIs the back of your iPhone's wireless charger hot? It's a normal phenomenon. When an iPhone is charged using a wireless charger, it is normal for the back of the phone to get hot. This is because when wireless charging, the phone's built-in battery will accept the electrical energy from the charger and convert it into electrical energy storage. In this process, part of the electrical energy will be converted into heat, causing the back of the phone to burn.
2, temperature control circuit. General wireless charging scheme will have a temperature control circuit and NTC thermistor, this function is mainly for wireless charging body hot to prevent electricityThe heat generated by the road in the process of working is too high, burning components, etc., and you can also control the power components after generating too much heat, reduce the power, thereby reducing the temperature. Selection of heating components. qi standard wireless charging is originally the use of electromagnetic induction, generate current, promote the circuit work.
3, if you are wireless charging, because there will be energy loss in the wireless transmission process, and then produce a certain amount of heat, there will be a phenomenon of wireless charging heat, this is normal.
4, the reasons for this situation are as follows wireless charging body hot : Too many background running procedures: you can properly close the background running; Caused by abnormal mobile phone charger: When replacing the mobile phone charger, it is necessary to replace the charger that matches the mobile phone according to the model of the mobile phone.
5, wireless charging mobile phone hot is a normal phenomenon. In the process of wireless charging, the hot mobile phone is the result of a variety of factors. The following will explain in detail why the mobile phone will be hot when wireless charging from the working principle, energy conversion efficiency, mobile phone heat dissipation design and use environment. First, the working principle of wireless charging involves electromagnetic induction or magnetic resonance, whichIs electric perm normal
[Pacific Auto network] not normal. Because the mobile wireless charging device of the mobile phone in wireless charging, the heat itself is serious, if the heat continues, it will cause irreversible damage to the components of the mobile phone, including the motherboard and battery, so the equipment manufacturer can only reduce the temperature rise by reducing the charging current, so when the temperature of the mobile phone reaches a certain threshold, its wireless charging efficiency will be very slow.
Measured, SAIC Roewe RX Weilai ET5 and BMW 7 Series support Apple fast charge protocol, so the test results are satisfactory, charging within 15 minutesThe amount reaches or exceeds 10%, and the charging efficiency is even higher than the direct use of wireless chargers.
This is the weakness must be slow, the original wireless charging is like this, occasionally used, usually they are using the data cable this is a decoration, with Apple's special charger is not hot, and very fast, the car wireless charging speed is slow, this may be because the car charger you use does not match your mobile phone model, so the charging is slow.
IfYou are conducting wireless charging, because there will be energy loss in the wireless transmission process, and then generate a certain amount of heat, there will be a phenomenon of heat when wireless charging, this 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.
【 Pacific Auto network 】 BMW 5 series wireless charging mobile phone hot is not normal. Since the mobile wireless charging device of the mobile phone is wireless charging, BenIf the heat continues, it will cause irreversible damage to the components inside the mobile phone, including the motherboard and battery, so the equipment manufacturer can only reduce the rise in temperature by reducing the charging current, so when the temperature of the mobile phone reaches a certain threshold, its wireless charging efficiency will be very slow.
Hot is a normal phenomenon. The current technology in the electromagnetic conversion process of wireless charging will lose a lot of electricity with heat, whether it is the receiving end or the transmitting end, there will be a certain energy loss.
1, BMW wireless charging mobile phone hot not more than 60 degrees is normal. Most BMW cars have a wireless charging pad in front of the shift lever, and you can charge your phone by simply placing the mobile phone that supports wireless charging on the charging pad. The reason why the battery is hot when charging is that the resistance is working when the power circuit is running during the charging process, and the resistance and current interact, and heat is inevitable. The resistance and current are mainly concentrated in the battery and the internal PCB board.
2, 【 Pacific Auto network 】 BMW 5 series wireless charging mobile phone hot is not normal. Thanks to mobile wirelessCharging equipment in wireless charging, the heat itself is serious, if the heat continues to cause irreversible damage to the mobile phone internal components including the motherboard, battery, so the equipment manufacturers can only reduce the charging current to reduce the temperature rise, so when the mobile phone temperature reaches a certain threshold, its wireless charging efficiency will be very slow.
3, BMW wireless charging mobile phone hot not more than 60 degrees is normal. Most BMW cars are equipped with a wireless charging pad in front of the shift lever, and you only need to put the mobile phone that supports wireless charging on the charging pad, you can charge the mobile phone.
4Overall, the 10 models that participated in the test and compared the more prominent performance is the BMW 7 series, which not only has a high charging efficiency, but also can effectively control the heat of the mobile phone, but it is a bit of a pity that the wireless charging function cannot be manually turned off. In contrast, the overall performance of long comfortable Da and BYD Seagull is relatively laggard, not only ranking at the bottom of charging efficiency, but also having certain problems with the control of mobile phone heat.
5, generally will not, the wireless charger current is generally small, will not cause too much damage to the battery. If it is an Apple wireless charger, it will discharge after 100% full, thenThen charge it again to 100% and repeat the process until the device is unplugged. But also to master the charging time, should not be too long.
