The charge efficiency is not high. Once the distance is a little far away, the efficiency of charging will be dramatically reduced, and a lot of time and resources need to be wasted to complete the charging, so the use is not meaningful. Safety issues in the charging process. High-power wireless charging equipment will produce a large amount of electromagnetic radiation, which will cause certain adverse effects on health, but also have interference effects on aircraft and communications. The first practical aspect.
Lack of wireless charging of mobile phonesAlthough the technical content of the equipment is high, the economic cost of the equipment is higher and the maintenance cost is large. Because of the realization of long-distance high-power wireless magnetoelectric conversion, the energy consumption of the equipment is high. As the distance and power of wireless charging devices increase, the loss of idle work will be greater.
Protection interface: Cable charging requires frequent insertion and removal of the charging cable. Long-term use may cause damage or wear of the interface. Wireless charging eliminates this problem, and the phone interface can remain in good condition for a longer time, extending the service life of the phone. Low charging efficiency: Compared with wired charging, wireless charging is less efficient.Reliance on a specific charging cable. Users no longer need to carry and connect a specific type of charging cable, and can charge at any time on multiple charging docks that support wireless charging.
Wireless charging may lead to accelerated battery wear and shorten battery life. Slow charging speed Wireless charging speed is relatively slow, temporarily can not be compared with wired charging. Wireless charging requires users to hold a charging board or use a special wireless charging seat, for frequent mobile phone users, charging while using the situation is very common, which may bring some inconvenience to use.
Wireless chargingThe advantages are: reduce the loss, high adaptation rate, the disadvantages are: the distance is too small, only the transition technology; The benefits of wireless charging reduce the loss. As we all know, when using wireless charging, you only need to connect the wireless charging board to the power supply first, and then place the device that supports wireless charging on the wireless charging board.
Low efficiency: energy storage and transmission efficiency is not as good as real contact. Slow charging speed: Due to low efficiency, the charging speed is slow at the same input power. High cost: the charger needs to have an electronic circuit to push the wireless coil, and the electrical device needs to have a power changeElectronic devices, both also need to have wireless coils, so the cost is higher than direct contact.
2, mobile phone wireless charging because there is no need to frequently plug and unplug the charging cable, so the mobile phone wireless charging experience data interface wear will be reduced a lot. At the same time, mobile phone wireless charging wireless charging experience coil is not exposed in the air, can also reduce the oxidation corrosion of the charging unit. The wired charging is often inserted and removed easily lead to wear, and the interface is exposed and easy to oxidizeCorrosion. Although wireless charging has many advantages, it is also found that there are many disadvantages in the actual use process.
3, convenient: wireless charging belongs to one-to-many charging, which solves the problem that the interface is not applicable, and also avoids the phenomenon of poor contact caused by repeated plugging and unplugging of the mobile phone interface, which can better protect the mobile phone interface. Safety: With a variety of protection functions, such as: overcharge and overdischarge, metal foreign body detection and other functions, always protect the safety of users.
4, one of the advantages of wireless charging is convenient. Compared with traditional charging methods, wireless charging can be used without plugging the charging cable, onlyYou need to place the phone on the charging dock. This process is very simple, allowing users to more easily charge. In addition, because the Mi Mix2s supports fast wireless charging, it can quickly fill the phone battery, thereby reducing the user's waiting time. However, there are drawbacks to wireless charging.
5, the shortcomings of mobile phone wireless charging although the technical content of the equipment is high, the economic cost of the equipment is high, and the maintenance cost is large. Because of the realization of long-distance high-power wireless magnetoelectric conversion, the energy consumption of the equipment is high. As the distance and power of wireless charging devices increase, the loss of idle work will increaseLarge.
6, the disadvantages of wireless charging efficiency is slightly lower: the general charger also has a transformer, but the wireless charging transformer composed of the transmitting coil and the receiving coil is limited in structure, and the energy transmission efficiency is theoretically slightly lower than that of the general charger. Slow charging speed: Due to the current mobile phone and other receiving devices, most limit the input power, so the charging speed is slow.
In addition to convenient wireless chargingCompared with the traditional charging method, the biggest advantage of wireless charging is convenient. When the mobile phone is out of power, it can be charged directly on the wireless charging cover plate, without inserting a cable, which is more convenient. I have a wireless charging module in the car, throw it directly into the car, and it will automatically charge. In addition to the advantages of convenience, wireless charging has many disadvantages.
Advantages: Convenience: no need to connect the charging cable, which can make the user more convenient to charge. Safety: It avoids the safety hazards caused by the charging cable and reduces the risk of fire. Avoid damage: Reduce the plug and unplug of the charging cable, can extend the charger and deviceThe service life. Disadvantages: Relatively slow: wireless charging is slower than wired charging, and the charging speed is slower.
Mobile phone wireless charging and wired charging, charging head and mobile phone need to increase the charging coil, and related support circuit. At the same time, high frequency wave circuits are also required to meet electromagnetic compatibility, so the overall price is higher than traditional wired charging.
The benefits of wireless charging reduce the loss As we all know, when using wireless charging, just connect the wireless charging board to the power supply, and then place the device that supports wireless charging on the wireless charging board. Wireless charging still requires a power connection, but it canIt can reduce the use of data lines and avoid a large amount of loss and waste of data lines, which is relatively an environmentally friendly charging method.
Low efficiency: energy storage and transmission efficiency is not as good as real contact. High cost: The charger needs to have an electronic circuit to promote the wireless coil, and the electrical device needs to have an electronic device to change the power, both also need to have a wireless coil, so the cost is higher than the direct contact. Slow charging speed: Due to low efficiency, the charging speed is slow at the same input power.
Convenience: non-contact, one-to-many charging compared with the general charger, reduces the trouble of plugging and unplugging at the same timeAlso avoid the interface is not applicable, poor contact and other phenomena, the elderly can also be very convenient to use. Versatility: A charger can charge multiple loads, and a family can buy a charger to meet the needs of the whole family.
1, my mobile phone is not the kind of positive and negative can plug the charging interface, especially when the wireless charger is the most practical, which greatly reduces the frequency of plugging and unplugging of my data cable, and I am livingIn first-tier cities, wireless charging is everywhere, and you never worry that your phone has no electricity in the middle, which gives you the feeling of using high-tech.
2, especially high B, but the cost is high. The charger needs an electronic circuit to push the wireless coil, and the electrical device needs an electronic device to change the power, both of which also need a wireless coil, so the cost is higher than that of direct contact.
3, iPhone SE2 is my first Chinese mobile phone, I feel the pain of not being able to use the Face Time phone function, and I have long been sure that the next iPhone must buy the Hong Kong versionAnd let my iPhone castrate my Face Time phone.
Protection interface: Wired charging requires frequent insertion and removal of the charging cable, long-term use may cause damage or wear of the interface. Wireless charging eliminates this problem, and the phone interface can remain in good condition for a longer time, extending the service life of the phone. Low charging efficiency: Compared with wired charging, wireless charging is less efficient. That means it takes longer for users to fully charge.
Wireless charger is good, convenient, safe and durable; The disadvantages are bondage, high price and low efficiency. Advantages of wireless charger: Convenient: wireless charging belongs to one-to-many charging, which solves the problem that the interface is not applicable, and also avoids the phenomenon of poor contact caused by repeated plugging and unplugging of the mobile phone interface, which can better protect the mobile phone interface.
The advantages of wireless charging are: reduce loss, high adaptation rate, the disadvantages are: the distance is too small, but the transition technology; Charging can not play with the mobile phone, etc., the specific content is as follows: The benefits of wireless charging reduce the loss as we all know when using wireless charging, just the first will be noConnect the cable charging board to the power supply, and then place the device that supports wireless charging on the wireless charging board.
