But the advantages of wireless charging are also very obvious. Since there is no need to plug and unplug the charging gun, the convenience of charging is significantly improved, and the risk of electric shock is reduced. More importantly, if dynamic wireless charging mode is deployed, it can greatly reduce the amount of battery power carried by electric vehicles, reduce the cost of the vehicle, and completely solve the user's driving range anxiety.
Second, wireless chargingIf electric technology wants to be truly popular, it also has high requirements for the precise positioning and intelligence of vehicles. Only when the vehicle is precisely parked in the charging space can the ground system establish a channel with the vehicle's on-board system and achieve charging. In the case of precise positioning, the same footprint, the number of electric vehicles using wireless charging compared with the traditional charging pile charging will be greatly increased, greatly improving the space utilization and charging efficiency.
Wireless charging of electric vehicles is very strange to consumers, it is like we look at the concept car is a future scene. However, if it can be achieved, it can greatly alleviate the inconvenience of charging?
Mobile phone wireless charging is not popular, mainly because the wireless charging experience is very rubbish. Of course, the high price is also a very important factor. In terms of experience, mobile phone wireless charging has shortcomings. Compared with wired charging, wireless charging of mobile phones is not only slow, but also very inconvenient to use wireless charging. Slow charging speed: Since the Samsung Note 7 explosion, mobile phone wireless charging power has been castrated by manufacturers.
Wireless charging Charging speed is extremely slow, which is hard. Now is the world of high-power fast charging, although each fast charging solution is not the same, but the power is fundamentallyMaintained at about 18w, high and even to 24w, used to fill within one and a half hours, but now to return to the past, 5w 8w maximum 10w charging speed, is not acceptable, but also can not move, the position is biased, the speed is lower.
And now most of the mobile phones on the market are metal back cover, wireless charging needs glass or ceramic back cover, in a wide range of can not meet the needs of most people.The disadvantage of wireless charging is that most of the efficiency of wireless charging is relatively low. Because relying on electromagnetic induction to charge, oftenThe speed is relatively slow, and sometimes it is necessary to quickly fill the mobile phone, so it is obvious that wireless charging is not as fast as directly using the mobile phone to charge the data line.
Wireless charging support for the factory flagship machine, the price is too expensive, which should be a very important factor. Looking at all the models that support wireless charging on the market at present, most of them belong to the flagship positioning and are expensive, such as Samsung Galaxy series, Apple iPhone X, iPhone8 series, the price of these products is often five or six thousand yuan, or even higher, which is destined to have a relatively small audience.
Slow wireless charging In terms of efficiency, wireless charging is still relatively low. At present, the wireless charging used by mobile phones is not really wireless charging, but the way the data cable is connected to the charging pad and the phone is charged on the charging pad. Wireless charging is not popular, mainly due to its own limitations. In the mobile phone sector, only Samsung has 15W wireless charging power.
Wireless shared charging can not be recognized by the market because of himIt was just invented, so there are still very few people who know this, so it is not recognized by people. And it's kind of a hassle, you know, lending it out and giving it back takes time. Whether it is communication, payment, travel or ordering, the importance of mobile phones has covered every corner of life. When wallets and card bags are lost, phones are increasingly indispensable.
The main thing is the difference in values: for some young people, buying a higher-priced mobile phone may represent their pursuit and values for fashion, technology, quality, etc., while using a shared charging bank may be considered a low-end, cheap choiceTheir values don't match.
In contrast, the shared charging treasure is usually only a small, scene-dependent life tool, can not symbolize the social status of consumers, so it will be ignored by some consumers. Secondly, when consumers choose to buy mobile phones or shared charging banks, they usually consider the practicality and use experience of the products.
Uneven service quality: Because the competition in the shared charging treasure market is very fierce, many shared charging treasure operators do not hesitate to fight a price war, which leads to the uneven service quality of many shared charging treasure. Environmental impact: Manufacturing, transportation,Maintenance and recycling will have a certain impact on the environment.
