1, advantages: convenient. Just put the phone in the designated position of the car, you can wireless charging, no need to use the data cable to connect the phone and the car, it is very convenient to use. Good compatibility. The use of data cable charging needs to choose the appropriate cable according to the mobile phone charging port, such as type-c and Apple data cable, and wireless charging does not need to distinguish, canIt's infinitely compatible. Cons: Slow charging speed.
2, the advantage of automobile wireless charging technology is that there is no exposed connector for electric vehicle wireless charging, which can adapt to a variety of harsh environments and weather, and avoid safety hazards such as leakage and electricity running. 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.
3, the advantages and disadvantages of wired charging and wireless charging The advantages of wired charging is fast charging speed, good stability, but also at the same time for data transmissionLose. 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 device needs to be placed on the charging base, which is not flexible enough.
4, this wireless charging technology is superior to electromagnetic induction wireless charging technology, 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. Wireless charging technology is notAlthough there are some years of development, but many problems restrict its general application. Wireless charging opens up a new charging mode for smart phones, getting rid of the shackles of traditional charging data cables.
5, durable: the power transmission element is not exposed, so it will not be eroded by moisture and oxygen in the air; There is no contact, so there is no loss caused by mechanical wear and flaring during connection and separation. Convenient: there is no need to connect with wires when charging, as long as it is placed near the charger, there is no need to occupy multiple power sockets, and there is no trouble of multiple wires winding each other.
6, obviously, wireless chargingCharge fast and charge slowly. The power that the charging head wired outputs to the wireless fast charge base is not the wireless fast charge output power but the wireless fast charge input power. Charging time of more than 2 hours of wireless fast charge, not as fast as the wired fast charge of 1 hour and 30 minutes, is not fast charge. Unexpectedly, the wireless fast charging efficiency of 60% when the 18W is charged for 2 and a half hours.
In general, the conversion efficiency of car wireless chargers is limited, but by choosing a reasonable charger, we can improve the situation. Although the speed of wireless fast charging is not fast, it is not too slow, and consumers should pay attention to the power and actual charging of the charger when purchasingEfficiency. In fact, it has to be said that the current wireless charger does have a lot of shortcomings, and in the actual use of the process, there is indeed a slow charging speed, wireless charger is relatively less embarrassing situation, it is precisely because of this, these technologies need to continue to improve, I believe that the future one day wireless router will become more and more convenient, But also can realize the true sense of wireless charging.
1. Reasons for slow wireless charging of new energy vehicle mobile phoneThe reason is as follows: the external charger, this charger is also divided into many kinds of charging power, in the case of vehicle support, the greater the power, the faster. The reason for the car internal charger needs to be checked. The cause of the mobile phone battery, the balance of the battery and the temperature will affect the speed of charging.
2, most of today's mobile phones support wireless charging. You just need to put the phone on the wireless charging pad and charge it. Although the speed of wireless charging is slower than that of wired, wireless charging is simpler and faster to a certain extent. If this technology is used in our new energy vehicles, noIs it particularly interesting? Recently, the National Standards Management Committee issued four national standards on wireless charging of electric vehicles.
3, followed by the fever problem. I believe many people will have this experience, the mobile phone on the car wireless charging a few minutes, the body will be hot. At this time, the mobile phone that is charging is like a time bomb, which can only be cooled down by blowing on the air conditioner outlet for a long time.
4, because the AC charging pile charging power is small, so the efficiency is low, the charging time takes about 5-8 hours, the longest or even more than 30 hours. Fit model almost100% of new energy vehicles can be charged in this way, but due to the slow charging speed, it is more suitable for vehicles with a long shutdown time or plug-in hybrid models with small battery capacity, such as Trumpche GS4PHEV, BYD Song DM, BMW X1PHEV and so on.
5, the use of automatic wireless charging method. The principle of charging is to configure a charging pad at the charging place, and also configure a charging pad at the bottom of the car, and install a micro-navigation system on the car to ensure the accurate docking of the two pads, so as to start charging. Somewhat similar to the current mobile phone charging, put the phone on the charging mat can be. It's a kind ofNew charging methods, there are still many places to improve. New energy vehicles are the future direction of development.
1, the speed of charging is related to the size of the output current of the charger, the output current is fast, and the opposite is slow. The slow charging of the cigarette lighter you use is most likely caused by the small output current of the charging head inserted into the cigarette lighter. Cigarette lighter is a device in a car. The traditional cigarette lighter draws electricity from the car's power source,Heating metal electric heating sheet or metal electric heating wire and other electric heating units for lighting smoke ignition source.
2, the most intuitive difference is the difference in power, the power of a car charge is 10 watts, the power of another car charge is 20 watts, which also leads to the difference in its charging speed, 20w wireless car charging speed is much faster than 10w. The appearance of the car charger is different, the front panel ring indicator of the 10w wireless car charger is replaced with a blue indicator, and there is no on-board charger.
3, the principle is relatively simple, is the first wireless charging device plugged into the socket, the electricityIt can be converted into a special signal source, and the mobile phone within the radiation range of the signal source can automatically identify the signal, and when the mobile phone receives this signal, it can be converted into electricity to complete the charging.
4, the most direct difference is the output power is not the same, the output power of a car charger is 10 watts, the output power of another car charger is 20 watts, which also causes the charging rate is not the same, 20w wireless car charging rate is much more than 10w. The appearance Settings of the car charger are different, and the ring display light of the front face control panel of the 10w wireless car charger is changed to the dark blue display light, and there areAdditional car stop charger.
