3, wireless charging technology mainly through electromagnetic induction, magnetic resonance and other ways to achieve non-contact power transmission. For electric vehicles, electromagnetic induction and magnetic resonance are the two main wireless charging methods.Electromagnetic induction wireless charging is suitable for fixed parking Spaces and charging when the vehicle is parked, while magnetic resonance can achieve mobile charging, but it requires large-scale upgrading of road facilities and has a high cost.
4, secondly, wireless charging power is low and the cost is high. The current passenger car wireless charging power is up to 11kW, the efficiency is lower than wired charging, the equipment cost is more significant, a 3kW wireless charging system price of more than 10,000, and the same efficiency of AC slow charging pile only more than 1,000. The high cost and low efficiency make the popularization of wireless charging technology face serious challenges. Plus, wireless charging beltThe resulting receiving current instability problem. The cost issue. Road construction, at present, there are only a handful of roads in the world that can implement and lay charging coils, and the renovation and construction of roads also require many aspects of planning and design.
Second, the power of wireless charging is low and the cost is high. The current passenger car wireless charging power is up to 11kW, the efficiency is lower than wired charging, the equipment cost is more significant, a 3kW wireless charging system price of more than 10,000, and the same efficiency of AC slow charging pile only more than 1,000. The high cost and low efficiency make the popularization of wireless charging technology face serious challenges. Furthermore, noneThe problem of electromagnetic radiation caused by line charging cannot be ignored.
The current technical bottleneck is mainly on the battery. Now the most used lithium battery in China, the disadvantage is that the cost is very high, almost the cost of a battery and the original cost of the same level of traditional cars; The second is that the power can not meet the requirements of the use of modern cars, that is, the driving range is short, and charging is very troublesome, if the fast charge must have a special charging station, but now the supporting facilities are not perfect.
1, efficiency problem Wireless charging is subject to the development of technology, charging efficiency is still relatively poor, because the wireless charging itself is small power, and the actual performance is not stable.
2, the disadvantages of wireless charger: bound: wireless charging needs to be adsorbed on the charging base, can not be moved at will, the user is more bound than wired charging. High price: The principle of wireless charging is different, resulting in the cost of wireless chargers is usually higher than that of wired chargers.
3, disadvantages: the charging speed is relatively slow. In the era of fast mobile phone charging, wireless charging is very slow. Now most of noneLine charging only supports 5W charging, and slightly faster charging is only 5W. And wireless charging really can not meet our needs.
4, another major drawback of wireless charging is that it tends to limit us to a relatively close distance, and sometimes the wireless charger must put the phone in that position, if it moves, the phone can not be charged at all. If some friends like to sit and play mobile phones, then wireless charging at this time limits the posture of playing mobile phones, which is very inconvenient.
Advantages: Convenience. Just put the mobile phone in the designated position of the car wireless charging affect the car , you can wireless charging, no need to use the data line to connect the mobile phone and the car, it is very convenient to use. Good compatibility. The use of data cable charging needs to select the appropriate wireless charging cable according to the mobile phone charging port, such as type-c and Apple data cable, and wireless charging does not need to distinguish, can be unlimited compatible. Cons: Slow charging speed.
The advantage of automobile wireless charging technology is electric vehiclesWireless charging has no exposed connector, can adapt to a variety of harsh environments and weather, to avoid leakage, electricity and other safety hazards. The disadvantage is that the power is small, it can only be slowly charged, and the transmission efficiency is lower than that of wired charging. Inductive charging is more stringent for vehicle location. In addition, compared with the charging pile, the cost is higher, and the charging standards of various brands are different.
This wireless charging technology is superior to electromagnetic induction wireless charging technology, which not only extends the transmission distance, but also does not require the position between the coils to be completely consistent. In addition to the above two wireless charging technologies, there are also electric field coupling wireless charging technology and microwave resonance wireless charging technology. Although wireless charging technology has some years of development, many problems restrict its universal application. Wireless charging opens up a new charging mode for smart phones, getting rid of the shackles of traditional charging data cables.
Advantages and disadvantages of wired charging and wireless charging The advantages of wired charging are fast charging speed, good stability, and data transmission can also be carried out at the same time. The disadvantage is that the connection line is required and the use is not convenient enough. The advantage of wireless charging is that it is easy to use, does not require a cable, and only needs to put the device on the charging base to charge. The disadvantage is that the charging speed is slow, the charging efficiency is also low, and the charging bottom is also requiredThe equipment placed on the seat is not flexible enough.
1, as long as the mobile phone has wireless charging function, any mobile phone can be wireless charging, without limiting the mobile phone brand. Mobile phone wireless charging is very convenient, just need to power the vehicle, and then put the phone on the charging panel can be achieved. Can car wireless charging be installed? Can be added. You just need to buy a wireless charging module and connect the module's connection port to the vehicle's cigarette lighter through a transfer switch.
2, carWireless charging As long as the mobile phone supports wireless charging function can be charged, if the mobile phone does not support, you need to connect a wireless charging patch on the mobile phone. At present, the car charger basically uses the QI protocol (wireless charging standard), and the mobile phone and the car charger that meet this protocol can be matched for charging. So as long as the transmitter and receiver are QI certified, they can basically be charged.
3, the use of wireless charger is very simple, only need to place the phone on the wireless charger can be. During the charging process, the phone does not need to use a data cable connection, and does not produce interference or dangerous wiresOften convenient and safe.
4, as long as the mobile phone with wireless charging function, any mobile phone can use wireless charging, will not limit the brand of mobile phone, mobile phone wireless charging is very convenient to use, only need to power the vehicle, and then put the mobile phone on the charging panel, it can be achieved.
5, fixed wireless charger. The owner needs to buy a suitable wireless charger equipment, and then fix the wireless charger on the vehicle, and the fixed position should be convenient for the owner to take. Connect the cigarette lighter. One end of the USB data cable of the wireless charging device is connected to the wireless charger, and the other end is connected to the car cigarette lighter interface. Put it in your phone. Put your phone in a wireless charger and it will start charging.
6, the steps to use wireless charging on the car are quite simple. First, fix the in-car wireless charger in the appropriate location in the cab to ensure that it is stable and easy to use. Then, plug one end of the USB data cable of the wireless charger into the cigarette port of the car, and connect the other end to the wireless charger. Then, adjust the position of the wireless charger to ensure that it is firm and does not slide. Finally, place the phone on a wireless charger to start charging.
