Wireless charging technology still needs continuous development, at present, the wireless charger is not practical, and itself is not convenient, so it needs continuous development and technical improvement.
Wireless charger is often not attached, but need to buy additional, so for many people, spend a few hundred yuan to buy a charging base is often not very cost-effective, and sometimes a charging base is difficult to reflect the real portability of wireless charging, often need to buy more than one, buy one or more at home, put one in the car, The company buys another one, and the manufacturer's own wireless chargerIt's not cheap.
Most mobile phones do not support wireless charging The concept of wireless charging mobile phones basically everyone knows, but there are not many mobile phones that support wireless charging, and most mobile phones that support wireless chargers are high-end flagship machines. According to the latest purchase report, most people now use mobile phones are about 2000 yuan, the cost of wireless charging is generally more expensive, and mobile phones in this price segment generally do not have wireless charging technology.
I'm using a stand wireless charger and a car wireless charger. One on the desk, one on the car, readily put the power can be added, convenientVery. Say no one uses the electronics factory workers! People who sit in the office like wireless charging, and they put it in the company every day and pick it up when there is news. The charge is slow, but the whole day is full. The staff of the Communications Department of the Ministry of Industry and Information Technology said that it is inevitable that the wireless charger has radiation, but since it has been listed, it means that it must meet international standards and will not cause great harm to the human body. For this view, He Guili, director of the Tel Laboratory of the Telecommunication Research Institute of the Ministry of Industry and Information Technology, agreed: "Wireless chargers as long as they are done in accordance with technical specifications, there will be no radiation harm to the human body." But there's one more.The key question.
Yes. The mobile phone is charged on the bed, resulting in heat that can not be dispersed in time, causing the battery temperature to be too high, the battery bulge will occur, and the battery will fire and explode directly in serious cases. Mobile phones, all known as mobile phones or wireless phones, were originally just a communication tool, and in the early days, there was the common name of mobile phones.
Many small partners may have the habit of playing mobile phones before going to bed, and then put the mobile phone on the bed to charge, which is also more dangerous: the phone will become hot during charging, such asIf it is accidentally rolled into the quilt, or accidentally pressed when sleeping, it is easy to bring safety problems, so it is still necessary to charge away from the bed.
When we charge the mobile phone, it is best to use their own original charger, because the original charger is the most suitable for their own mobile phone charger, if you use other chargers may damage our mobile phone, so that the mobile phone is easy to charge bad, bulging. In particular, it can not be charged in a high temperature environment, such as in the sun, where the temperature is very high, the mobile phone itself has a slow cooling function, if you play it again at this time, it is easy to cause an explosion.
2, first power off the wireless charger on the Haval dog. Secondly, add a cooling rack to the wireless charger. Finally restart the connection.
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, use the standard charger and data cable charging; Do not allow objects to cover the surface of the charger; In case of feverIf it is serious, please stop charging and take the device to vivo customer service center for testing. 5, there are several suggestions can effectively improve the phenomenon of charging heat, you can try subsequent use: use the standard charger and data cable charging, due to the specifications of the third-party charger and charging protocol is different, may bring heat to the phone and other problems. Please use the standard charger and data cable to charge to ensure stable charging speed and safe use.
6, other reasons for mobile phone charging heat: mobile phone is still in use when charging. The phone is not charged with the original charger.Charge your phone with a case.
1, under normal circumstances will not harm the mobile phone, wireless charging now the working frequency is done below 1M, so the signal of the mobile phone will not have an impact. Wireless charging has no effect on mobile phone battery life, and wired charging is basically the same, but the rate is lower, but the wireless charger conversion rate is still high, more energy saving.
2, no harm to mobile phones. The wireless charger uses the latest wireless chargeElectrical technology, through the use of alternating magnetic fields generated between the coils, the transmission of electrical energy, inductive coupling technology will be the bridge connecting the charging base station and equipment. 3, from the theory, wireless charging technology is safe and harmless to the human body, the resonance principle of wireless charging is magnetic field resonance, only in the same frequency resonance between the coil transmission, and other devices can not accept the band, in addition, the magnetic field used by wireless charging technology itself is harmless to the human body.
4, wireless charger is not harmful to the phone. The wireless charger uses electromagnetic induction technology, which is generated by using magnetism between coilsThe field transmits energy, which couples the current from the charging disc to the phone battery, and the charging process for the battery is no different from that of an ordinary wired charger.
5, basically no damage: wireless charging technology uses the principle of electromagnetic induction, through the magnetic field and electromagnetic field to transmit electricity, this process has no direct damage to the internal structure of the mobile phone battery. Modern mobile phones have built-in wireless receivers with voltage and current ratings, so wireless chargers are safe for mobile phone batteries under normal use.
For the human body: Wireless charging technology is safe and harmless to the human body. The resonance principle used by wireless charging is magnetic field resonance, which is transmitted only between coils resonating at the same frequency, and other devices cannot accept the band, in addition, the magnetic field used by wireless charging technology is itself harmless to the human body.
In fact, it is certain to tell you that the harm of wireless charging to the human body is very small, almost negligible. This is just like the Wi-Fi, mobile phones, televisions and other electronic products we use on a regular basis, and we do not exist in the launchThe radiation level between the device and the receiver is small, and the frequency that the body mainly absorbs is inconsistent with the charging frequency, so we can not worry about the harm of wireless charging.
Conclusion: Wireless chargers do produce electromagnetic radiation, although the value is usually small, but should be wary of its possible cumulative effect. With the popularity of wireless charging technology, users are exposed to more and more radiation sources in daily life, such as mobile phones, computers, WiFi, etc., and long-term accumulation may have an impact on health. Wireless charging Technology and controversy With the development of mobile Internet, the rise of wireless charging function has caused concern about electromagneticDiscussion of wave radiation.
Does wireless charging technology radiate the human body? Does it cause cancer? Tests have proved that wireless chargers can indeed produce electromagnetic radiation, but the value is relatively small. Now users are exposed to more and more radiation: computers, tablets, mobile phones, WiFi, televisions, microwave ovens... The cumulative radiation value is very high, and if the user lives in such a high radiation environment for a long time, it may cause serious harm to the body and mind.
In theory, wireless charging technology is safe and harmless to the human body, and the resonance principle used for wireless charging is magnetic field resonance, which only resonates at the same frequencyCoil to coil transmission, and other devices can not accept the band, in addition, wireless charging technology uses the magnetic field itself is harmless to the human body.
No, wireless charging does not degrade the battery's performance any faster. Battery manufacturers design the amount of energy stored in batteries to determine the amount of electricity we can use. The manufacturer sets a fixed upper cut-off voltage and lower cut-off voltage, and the electrical cycle between the two voltage ranges is achieved, as long as we choose the right voltage range, we can makeBattery cycles thousands of times.
Wireless charging does not affect the battery. Regardless of whether you use a wireless charger or a wired charger, even if you leave your hand on a wireless charging pad for a long time, or leave it on overnight, it is impossible to exceed the manufacturer's energy limit, and you cannot discharge power outside the manufacturer's lower cut-off limit.
Wireless charging itself will not cause damage to the battery, but the charging temperature is too high or too low and the charger material and other factors will have an impact, so it is recommended to use a regular genuine charger, and avoid a long time of fast charging. Wireless charging is a short-range wireless charging technologyCompared with traditional wired charging, it converts electromagnetic energy into electricity and transmits it directly to the receiver, so that the phone can be charged without connecting the charging line.
Wireless chargers have an impact on battery life. The use of wireless chargers has an impact on battery life mainly reflected in the following aspects: First, the wireless charger generates current through the electromagnetic field to charge the device, and its charging method may be slightly less efficient than wired charging. This means that some heat may be generated during the charging process.
Wireless charging does not affect battery life. Underhand wirelessThe working principle of charging, the factors affecting battery life, and how to safely use wireless charging are explained in detail. Wireless charging technology mainly transmits electrical energy through the principle of electromagnetic induction. In the process of wireless charging, there is no need for direct contact between the charger and the receiving device, but for energy transmission through the magnetic field.
