1, the amount of charging within minutes reaches or exceeds 10%, and the charging efficiency is even higher than the direct use of wireless chargers. In contrast, the Deep Blue SL0 and Wei Blue Mountain DHT-PHEV are obviously not too friendly to the Apple iPhone 13 Pro, with a 15-minute charge of 3%Compared with other test models, the gap is large.
2, "Electric vehicle wireless charging system Part 2: Communication Protocol between Vehicle charger and charging device" (GB/T 38772), "Electric vehicle wireless charging system Part 3: Special requirements" (GB/T 38773), "Electric vehicle wireless charging System Part 4: Electromagnetic environmental limits and test methods (GB/T 38774) a total of 4 national standards.
3, Millet and Huawei's highest charging efficiency need the mobile phone to support their own protocol, so weIt is in an ideal situation that infrared wireless charging can be carried out for devices 30 meters away, and the power of 400W reaches the device here only 85W. I don't know, it's really not practical at this stage.
To a certain extent, the user's biggest concern is whether wireless charging will produce a large amount of electromagnetic radiation, which will affect human health. This infrared wireless charging device in the process of work, if the transmission route is blocked, it will automatically reduce the power for protection. But considering that it does not yet have the ability to distinguish the human body from other physical objects, soThe effect will be greatly reduced when used in the partition wall.
At the same time, the South Korean government also subsidized the Korean telecom company, the roadside public phone booths into electric vehicle charging stations, not only to solve the problem of low utilization rate of phone booths, high maintenance fees, but also to solve the problem of inconvenient charging of electric vehicles. Next, the South Korean government plans to focus on solving the problem of long charging times for electric vehicles.
Kia Kia Motor Company, is the earliest car manufacturer in South Korea, founded in December 1944, Kia Motors formerly known as Kyungsung Precision Industry), located in Yeongdeungpo-gu, Seoul, moved to Busan during the Korean War, started as a small factory that made bicycle parts by hand, and in March 1952 produced the first bicycle in Korea, named Sanli, and the company was renamed Kia Industries.
Performance: EMUI0.0 (based on Android9), maximum support 256GB expansion, the new Kirin 980 dual-core NPU processor. It achieves comprehensive improvement of performance and energy efficiency, brings excellent game experience and battery life experience of full frame, powerful and efficient operation, wisdom, intelligence and perception system bring you fastAnd convenient life.
GarminVivofit The antithesis of Samsung GearFit is the GarminVivofit activity tracker. The device doesn't support notifications, GPS or a bright display. In fact, you don't need to charge it every night, as the device's built-in battery will last a full year.
Currently, MassachusettsThe institute of Technology has improved the effective distance of wireless charging to about two meters through resonant sensing technology, which is named "WiTricity", one of the researchers has since left to start a business and develop a system, but the price is more expensive, reaching $995 (about 6240 yuan).
Generally about 0.9-2 meters high-power wireless charging transmission distance up to 5 meters wireless charging technology can be divided into low-power wireless charging and high-power wireless charging two ways. Low-power wireless charging often uses electromagnetic induction, such as the Qi method of charging mobile phones, but ZTE's electricityThe inductive mode of wireless charging for motor vehicles.
The distance is greater than 10 cm, and the conversion efficiency is only about 60%, that is, the sent power is 1000W, and the received power is only 600W.
Limitation: large volume; Small power WiFi wireless charging: ten meters away Advantages: go with the charge, in line with the concept of wireless charging Disadvantages: charging object positioning is not easy, waste of power Ultrasonic wireless charging: effective range close to 5 meters Advantages: technology is very safe; The receiver is cheap and small; Can be used for data transmission. Cons: The final product may not workMeets expectations in terms of price, power, speed and safety.
The core magnetic resonance medium and long distance wireless charging developed by Spurotin can successfully achieve wireless charging within one meter.
If the charging efficiency is relatively normal and harmless to the human body, the farthest distance that can be done now should be 5-10cm, and the domestic micro goose technology and Qualcomm should be able to do it. And this is not the public familiar with Qi wireless charging, is magnetic resonance wireless charging, based on the principle of magnetic resonance. Although there are also wireless charging technologies that are 1 meter or even farther away, the current charging power of these areIt is too small, the charging speed is too slow, and it is difficult to put into daily use.
1, set the wireless reverse charging open to manual open, that is, it must be opened manually in the setting of Huawei car automatic sensor wireless charger can be opened and closed intelligent, so aseptic bumpy road conditions, built-in infrared sensor, near the mobile phone, clamping arm automatic opening and closing lock, strong clamping force mobile phone is not easy to fall off, can easily deal with various bumps, touch the left sensor easy to unlock. The phone can be taken out manually, which isThe sample operation is convenient and the room is closed freely.
2, Replace the adapter: if the fever is serious, it is recommended to buy a regular manufacturer adapter, with the support to use. If there is still heat under constant temperature, it is necessary to power off and cool down first, and then restart. Charging cable selection: Replace other charging cables to test wireless charging and confirm whether the problem is caused by the charging cable. Optimize the charging environment: Keep the wireless charger working area clean, flat and free of interference, while temporarily removing the phone case or choosing a thin case.
3, wireless charger frequently pick up and down will not hurt the battery, because now the battery is basicallyUsing lithium batteries, there is no limit to the number of charges. One of the biggest characteristics of lithium batteries is long life, durable, low self-discharge rate, no memory effect, and can have high power tolerance. The current of the wireless charger is generally small and will not cause much damage to the battery.
