The charging power is about 5A, and the wireless charging function is very convenient in the car. It is not necessary to carry a charger during daily use. Once the phone battery is low, it can be directly placed in the charging position to complete the phone charging. But now most cars have them. oneThe Magotan model under the Volkswagen brand is a mid-sized sedan.
Magotan's wireless charging power is about 5A. The wireless charging function is very convenient and can save the trouble of carrying a charger in daily use. Simply place the phone in the charging position to complete the charging, which is a feature of most modern models. Magotan is a midsize three-compartment model, currently on sale as the 2020 model, with a 4T turbo engine and a 0T turbo engine with a dry dual-clutch transmission and a wet dual-clutch transmission, respectively.
The wireless charging power of Magton models is about 5A, whichThis function is very convenient, making it unnecessary to carry a charger in daily use. It is only necessary to place the phone in the charging position to complete the charging, and this feature is now adopted by many models.
Magotan's wireless charging function provides about 5A charging power, which is a big highlight of the vehicle's internal convenience. In daily use, there is no need to carry the charger with you, just place the phone gently in the designated charging area, and you can automatically start charging. In fact, wireless charging has become a common feature of modern cars, and Magotan is no exception. As a midsize sedan from FAW-Volkswagen, Magotan offersA variety of power options.
Magan (Check the transaction price | model details) Wireless charging power is about 5A, there is a charging area under the new Magan center control, put the mobile phone in the charging area under the center control, you can easily charge. Compared with usb charging, wireless charging function will be much more convenient.
Legal analysis: The development of the standard is to regulate the use of wireless charging equipment, avoid harmful interference to all types of radio services carried out in accordance with the law, and maintain the order of air waves. Radio is a public resource, just like road resources, which need to be used rationally and not interfere with others, and the same is true for low-power wireless charging.
High-power wireless charging devices are prohibited mainly because they interfere too much with wireless signals. At present, wireless charging technology has beenIt is very mature and stable, without any problems in safety, but due to the amplification of power, it will bring some unexpected troubles to production and consumption in terms of signal interference.
Because there are now relevant policies to limit the power of wireless charging, although it is in the stage of soliciting opinions, but it may also affect the planning of the later manufacturers, the highest wireless charging rated power is 50W. And Xiaomi's 120W has not yet been mass produced and has been criticized, feeling very aggrieved. After all, the policy has not yet been implemented, and it is too early to speak.
Recently, the Ministry of Industry and Information Technology issued the "wireless charging (Wireless charging)Interim Provisions for Radio Management of Power Transmission Equipment (Draft for Comment), the interim provisions clearly indicate that the rated transmission power requirements of wireless charging are less than 50W. This is to prevent wireless devices from interfering with each other.
But just now, the Ministry of Industry and Information Technology suddenly came out with new news. From next year, the power of mobile wireless charging equipment will be less than 50W, which also seems to reflect the wireless fast charging technology of mobile phone products will be limited. Mobile phone wireless fast charge may be the highest will also be fixed at 50W, of course, there is certainly a reason for such restrictions.
The charger is aging or faulty. According to relevant information, the Huawei 50W wireless Fast charger displays 50W power when it is properly charged. If it is less than 50W, the charger may be aging or faulty due to prolonged use.
If wireless charging is at night, the situation of limited power is normal, which is a point that Huawei considers specifically for users. After all, when we charge at night, we will charge all night, so there will be some damage to the battery.
According to my understanding of the charger, the power consumption of the charger must be greater than or equal to the power consumption of the device, but if the charger power exceeds the power consumption required by the device, the device will not accelerate charging. Therefore, if the maximum power of the Huawei wireless charger is 40W, and the power of the charging head is 66W, the 40W fast charging cannot be achieved, but may cause safety problems such as overheating of the charger.
The application environment is harsh wireless charging transmitter is generally distributedPlaced on the ground of the parking space, if the parking space is outdoor, it is necessary to ensure that it can still work effectively even in harsh environments such as lightning, rain and snow, high temperature exposure, and low temperature freezing. Even indoors, you need to consider the possibility of being run over by wheels or trampled by pedestrians.
Wireless charging is through an electromagnetic field. Not the radiation risk of high-power fast charging. Only slow charge. It'll take a few hours. Hours. Why save a few seconds plugging in a socket? And wireless charging to improve efficiency requires precise berths. And wired charging actually requires very low parking accuracy, long wires ah. In addition to wired charging there arePlenty of room for improvement. Like a plug that comes off easily without being crushed.
The principle of wireless charging is magnetic induction, the magnetic flux of the magnetic field must be very large, the charging efficiency is low, which is harmful to human health and interferes with electronic equipment. And most of the cars don't have sensors.
Electric vehicle charging needs to be fast, wireless charging power is difficult to meet the standard of wired charging, in addition, wireless car charging because it belongs to high-power electromagnetic field, safety is also questioned.
