Ministry of Industry and Information Technology: Wireless fast charge must be less than 50w, why do this requirement?

1, for the reason why there is such a provision, the Ministry of Industry and Information Technology said: this is to regulate the orderly use of radio spectrum resources by wireless charging (power transmission) equipment, to avoid harmful interference to all types of radio services carried out in accordance with the law, and to maintain the order of air waves. I personally think that the use of radio frequency resources really needs to be more rational and orderly, otherwise there may be interference with radio signals, which will have adverse effects.

2, the author believes that this may be Xiaomi's first compliance with the Ministry of Industry and Information Technology on the "wireless charging (power transmission) equipment radio management interimProvisions (Draft for comment). The regulation requires that from January 1, 2022, mobile and portable wireless charging devices are required to have rated transmission power of no more than 50W. Although it is only a draft for comments, there is news that the 50W wireless fast charge cap policy has begun to be implemented.

3, Huawei P50 Pro support 50W Huawei Wireless Super fast charge, support wireless reverse charging. Note: You need to purchase a Huawei Super Fast Charging vertical wireless charger (Max 50W) or Huawei Super Fast Charging Wireless Car Charger (Max 50W) separately and with a specific 66W Huawei Super Fast chargerOver 3 hours. The advantage is that the charging current and power are lower, and the impact on the battery life of electric vehicles and the impact on the grid are smaller. The disadvantage is that the charging time of electric vehicles is longer, and it is difficult to meet the emergency demand for electric energy supplement.

2, the home charging method is directly from the low-voltage lighting circuit, the charging power is small, and the standard grid power supply of 220V/16A specifications is supplied. The typical charging time is 8 ~ 10h. This charging method has no special requirements for the power grid, and can be used as long as the power supply quality can meet the lighting requirements.

3, the main package of charging mode of new energy vehiclesIncludes portable charging, home charging and public charging. Portable charging is done by connecting to a home outlet using the portable charging cable that comes with the car. Home charging refers to the home charging pile provided by the user when purchasing an electric vehicle. Public charging refers to columnar charging piles or wall-mounted charging piles installed in parking lots.

4, 【 Pacific Auto network 】 The charging method of new energy vehicles includes conventional charging method and fast charging method. Conventional charging methods include constant current charging method, constant voltage charging method and stage charging method. The electric energy supplement of pure electric vehicles can be divided into two modes, namely, charging mode andPower change mode. Among them, electrical change is also known as mechanical charging, which is to achieve the purpose of electric vehicle electric energy supplement by directly replacing the charged power battery.

5, there are many ways to charge electric vehicles, mainly including the following ways: The use of portable chargers carried with the car: This charger can be charged by household power supply, very convenient. However, the charging speed is relatively slow, so it is more suitable as a way to replenish power. Home charging pile: When buying an electric vehicle, it is generally given a home charging pile along with the car, and the technician will install and debug it at the door.

6. strThe charging methods of ong new energy vehicles are diversified, mainly including portable, home and public charging three modes.

How big is Huawei wireless car charger plug

1, the car charger can be described as full of science and technology, not only the built-in fan cooling system, but also added an infrared sensor, as long as the phone is close, the body clip arm will automatically stretch and shrink, it is very convenient to use. In addition, it is also designed with DC circle and USB-C two input interfaces for owners to choose, practical. Today I will share with you this Huawei carDisassemble the wireless charge and see how its internal workmanship is designed.

2, HUAWEI's car charging technology is also excellent, Huawei HUAWEI Super fast charger car charger is equipped with dual USB interface, the maximum output power of 25W, free of the original fast charge data cable, for the journey of mobile phones and other electronic devices to provide convenient charging services.

3, z***s2021-02-14 Huawei 50 watt wireless car charger received the goods on the second day of the New Year, the Spring Festival can be delivered on time, Jingdong's logistics is really great. Open the package charger work fine, the front has been worried about the armrestThe cigarette lighter in the box is too long from the air conditioning position, afraid that the line is not enough, the result is that the line of the cigarette lighter plug is long enough, the length of one meter four. I use my own clip on the air conditioner, very secure.

4. Huawei mate50 supports wireless charging. Huawei Mate50 can support wireless charging, can support 40W Huawei Wireless Super fast charge, you need to purchase Huawei Super Fast charge vertical wireless charger or Huawei Super Fast charge wireless car charger, and use with a specific 66W Huawei Super fast charger. The Mate50 can also support wireless reverse charging, among current Android flagship phonesFor wired charging and wireless charging speed is very fast.

Wireless charging in cars is not widespread

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. And there's plenty of room for improvement in wired charging. Like a plug that comes off easily without being crushed.

Wireless charging technology has not been widely popular reasons: the number of terminals is less two years ago, Nokia Lumia 920 built-in Qi wireless charging technology, and randomly equipped with wireless charging board, but no other manufacturers followed up. Although some third-party manufacturers have also launched wireless charging accessories, but need to install a special shell, it is not compatible with other digital devices, the use of inconvenient form.

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. Most of the cars didn't pick upReceiving induction device.

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. In recent years, we can almost forget the existence of network cables, because mobile phones, tablets are basically built-in WIFI, some ultra-thin laptop computers have given up the traditional LAN interface, wireless network to some extent has replaced the cable. But why isn't wireless charging as popular as WIFI? First of all,The low number of terminals is the first problem.

Because the charger and the appliance transfer energy through the magnetic field, there is no wire connection between the two, so the charger and the appliance can be exposed without conducting contact. According to Baidu Encyclopedia, the wireless charging of mobile phone charging is actually low-power wireless charging, that is, electromagnetic induction charging, and wireless charging in the car is actually the output of electromagnetic induction wireless charging in the car.
