Convenience: non-contact car wireless charging characteristics , one-to-many charging compared with the general charger, reduce car wireless charging characteristics The trouble of plugging, but also to avoid the interface is not applicable, poor contact and other phenomena, the elderly can also be very convenient to use. (2) Versatility: a charger can charge multiple loads, and a family can buy a charger to meet the needs of the whole family.
The equipment using wireless magnetic induction charging can be invisible, the equipment wear rate is low, the application range is wide, and the public charging area is relatively reduced. High technical content, easy to operate, can implement relatively long distance radio energy conversion. Disadvantages of wireless charging: Although the technical content of the equipment is high, the economic cost of the equipment is higherElectrified roads ". Why so many attributes? This is because Sweden, Italy and the United States are also interested in this technology.
The maximum charging efficiency of Xiaomi and Huawei requires the mobile phone to support its own protocol, so we separately tested the situation of Huawei Mate 30 with Huawei wireless charging mobile phone bracket and Xiaomi 10 with Xiaomi wireless charging mobile phone bracket. The standard test uses the iPhone 11 pro with all wireless charging phone stands, and the rule is that the phone stays lit and the test charges 10% on all products under test (the phone battery is from 40% to 50%).
Compared with the electromagnetic induction type, the characteristics of the electromagnetic resonance type are obviously more in line with the needs of electric vehicle wireless charging. Soon after the technology demonstration was announced, WiTricity received offers from Audi, BMW, Chrysler, Jaguar, Nissan and Toyota to work with it. However, after receiving financial support, the development of wireless charging technology applied to electric vehicles has not been as good as expected.
The vehicle only needs 10 seconds to accelerate 100 km/h, with a top speed of 140 km/h, in WLTP test modeThe range can reach about 389 kilometers, which is 30% more than the range of the old model. It takes only 30 minutes to charge the 145km range with 50kW charging, and 9 hours and 25 minutes with 7kW charging to fully charge the vehicle. However, this powerful and popular small electric car starts at €20,000 in Europe, which is a bit expensive.
3, Wireless charging technology; Wireless charge technology is derived from radio energy transmission technology, which can be divided into two ways: low-power wireless charging and high-power wireless charging. Low-power wireless charging usually adopts electromagnetic induction, such as the Qi method of charging mobile phones, but ZTE's electric vehicle wireless charging method adopts induction [1].
4, automobile wireless charging technologyIt is an electric vehicle charging method that does not rely on charging cables, and realizes non-contact power transmission through electromagnetic induction, electromagnetic resonance, radio frequency and other ways to avoid safety hazards such as leakage and electricity running. Compared with traditional wired charging, it has the advantages of convenient use and no supervision, but the power is smaller and the transmission efficiency is slightly lower. Electric vehicle wireless charging mainly has two ways: electromagnetic induction and magnetic resonance.
The convenience of wireless fast charging does not bring a significant increase in charging speed, but may be slightly lower than wired fast charging. The power output of the wireless fast charger to the wireless base is not the final output power of wireless charging, but the input power of the wireless charger. The charging speed of wireless chargers installed on new energy vehicles is limited, which may be due to compatibility issues between external chargers and on-board charging systems.
However, in terms of current technological development, the efficiency of wireless charging is lower than that of wired charging. If wireless charging is used, there is no exposed connector when wireless charging of electric vehicles, completely avoiding leakage and electricity runningSecurity risks. And wireless charging can hide the power supply and transformer underground, so that the car can be charged in the parking lot or on the street special charging points, so wireless charging is very convenient.
The amount of charging within minutes has reached or exceeded 10%, and the charging efficiency is even higher than the direct use of wireless chargers. In contrast, the Deep Blue SL0 Long comfortable Da and Wei brand Blue Mountain DHT-PHEV are obviously not too friendly for Apple iPhone 13 Pro, with a 15-minute charge of 3%, which is a large gap compared with other test models.
First of all, the millet wireless charger carefully unbox, insideTake out the charger and place the wireless charger on a flat desktop. Secondly, there is a special Xiaomi charging head and charging cable in the package, and the charger is connected to the wireless charger with the charging cable, and a mobile phone supporting wireless charging is placed on the wireless charger. Finally, you can see that the phone is charging.
Xiaomi car charger fast charging version is very small, the use of all-metal material, the appearance of full texture. When inserted into the car, there will be a circle of white lights around. Before driving 20 minutes, the power can basically remain good, and now the use of millet car charger effect is very good, can be fullTens of percent of the electricity, the same as the original fast charge.
The mobile phones supported by Xiaomi wireless car charger are as follows: In addition to charging Xiaomi MIX 2S, Xiaomi wireless charger can also be compatible with mobile devices that meet the Qi wireless charging standard, including iPhone X, Samsung Galay S9 and other mobile phones. Features, millet wireless charger supports two charging modes, 5W universal charge and 7 point 5W fast charge. Sales information, millet wireless charger price of 99 yuan.
