1, 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 be largeReduce the amount of battery power carried by electric vehicles, reduce the cost of the vehicle, and completely solve the user's driving range anxiety.
2, secondly, wireless charging technology wants to be truly popular, and it also has high requirements for accurate 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.
3, small workWireless charging often uses electromagnetic induction, such as the Qi method of charging mobile phones, but ZTE's electric vehicle wireless charging method uses induction. High-power wireless charging High-power wireless charging usually adopts a resonant mode (most electric vehicle charging in this way) by the power supply device (charger) to transmit energy to the electric device, the device uses the received energy to charge the battery, and at the same time for its own operation.
4, the wireless charging of electric vehicles is very strange to consumers, it is like we look at the concept car is a future scene. But if it could be achieved it would greatly ease chargingng> the topic; The process of wireless charging will produce huge wireless charging future energy loss and a lot of heat (the same as the charging pile) wireless charging future , with the increase of power, the release of heat will be more wireless charging future , This has also become a major technical difficulty in improving wireless charging power (the greater the power, the hotter). 2, and it needs to be understood that the development of mobile phone wireless charging also represents the continuous progress and update of human science and technology, to usLife brings great convenience. Of course, the significance of early wireless charging for humans may not be very obvious, but it should be noted that the development goal of wireless charging is "energy WIFI", which is simply to keep up with the communication signal, so that the charging process does not affect the user's normal use experience.
3, in addition to the advantages, wireless charging also has some shortcomings. First of all, wireless charging is not very efficient. After a long time of use, it becomes difficult to fill due to the damage of excessive electrical energy. Secondly, the charging distance of the wireless charger also has a certain limit. Some traditional charging cables are available in lengthIt can be longer, so users need to weigh it carefully. In general, wireless charging technology provides another way to charge. In any case, we believe that with the development of science and technology and society, Apple's two-way wireless charging technology will gradually become popular. Compared with traditional wired charging, it is more convenient and flexible, and can bring more convenience and innovation to people's lives. Siri, Face ID, Apple Pay, Apple Watch and other technologies are all invented by Apple. Apple's two-way wireless charging technology will play an important role in future technical applications. 5, the emergence of wireless charging technology has brought us a lot of convenience, we do not have to drag a line to walk around, only need to put the mobile phone on the table can be transmitted, its principle is a total of three kinds, divided into electromagnetic induction magnetic resonance and radio wave type. Electromagnetic induction refers to the alternating current in the primary coil, which can produce a current in the secondary coil.
BatteryBattery life improves the current future of wireless charging , Intel Haswell chips have significantly improved battery life Future of wireless charging , up to 12 hours. If the battery technology can achieve a leap in the future, the use time of more than 24 hours on a single charge, and even support 2-3 days of battery life, it will greatly improve the portability and performance of the laptop, and greatly reduce the dependence on the power supply. The freedom of wireless connectivity Wireless connectivity is already widespread, but the future will be even more free and unfettered.
Improved battery life:Existing Intel Haswell chips have significantly improved battery life, but the goal in the future is to reach 24 hours or more. This means that users can carry out longer mobile office without frequent charging, which greatly improves the portability of the future of wireless charging. The convenience of wireless connectivity: Wireless technology will go further, laptops will no longer be limited to physical connectivity, and wireless charging and wireless peripheral connectivity will become the norm.
