1, wireless charging is through the electromagnetic field. Not the radiation risk of high-power fast charging. Only slow charge. It'll take a few hours. Hours. Why save a few seconds plugging in a socket? And wireless charging to improve efficiency requires precise berths. And wired charging actually requires very low parking accuracy, long wires ah. And there's plenty of room for improvement in wired charging. Like make it easyFalling off is not afraid to crush the plug. 2, wireless charging technology has not been widely popular reasons are: the number of terminals less two years ago Nokia Lumia 920 built-in Qi wireless charging technology, and randomly equipped with wireless charging board, but no other manufacturers follow up. Although some third-party manufacturers have also launched wireless charging accessories, but need to install a special shell, it is not compatible with other digital devices, the use of inconvenient form.
3, the principle of wireless charging is magnetic induction, the magnetic flux of the magnetic field must be very large, the charging efficiency is low, which is bad for human health and dry for electronic equipmentBother. And most of the cars don't have sensors.
4, electric vehicle charging needs to be fast, wireless charging power is difficult to meet the standard of wired charging, in addition, the car wireless charging because it belongs to high-power electromagnetic field, safety is also questioned. 5, the status of wireless charging products: The number of terminals is small and the standards are different in recent years, we can almost forget the existence of network cables, because mobile phones, tablets are basically built-in WIFI, some ultra-thin laptops have given up the traditional LAN interface, wireless network to some extent has replaced the cable. But why wireless chargingIsn't the technology as pervasive as WIFI? First, the small number of terminals is the first problem.
1, the charging time should pay attention to, it is recommended to use slow charging new energy vehicles to use slow charging generally takes 8-10 hours, and fast charging can charge 80% of the electricity in half an hour, and can be filled in 2 hours. However, fast charging of larger current and power will have a greater impact on the battery pack, charging too fast will also form a virtual battery, and over time will make the life of the power battery decline. theIf time permits, it is recommended that you preferentially choose the slow charging mode.
2, new energy vehicle charging and maintenance knowledge selection of new energy vehicles with the advantages of low cost of use, cheap maintenance, no tail number restriction requirements, no emission pollution, new energy vehicles have been vigorously promoted by the state, and have introduced multiple preferential policies. Among them, pure electric vehicles and hybrid electric vehicles are two more common on the market at present.
3, new energy vehicle charging precautions New energy vehicle charging voltage is high current, electricity safety is particularly important, so the switch on the car should be turned off when charging. And pay attention to try not to charge in direct sunlight in summer or in a high temperature environment after a long time of driving, and try to avoid charging operations in unsheltered wet open air or rainstorm weather. When charging, keep away from inflammable and explosive materials, equipment with electromagnetic influence, regulate operation, and pay attention to safety.
4, new energy vehicle charging precautions: vehicle charging system with high voltage, unauthorized modification of vehicle charging system components, vehicle charging equipment or touching damaged parts may lead to electrocution.
5, new energy vehicle charging method 1 to maintain the battery full electric state, ride electric moped every day, no matter 1050km, should be added to charge, so that the battery is in a "full state" for a long time, and on the same day, used up idle for a few days and then charged, prone to plate vulcanization, capacity decline 2 for regular deep discharge recommendations.
6, electric vehicles can be charged by fast charging, slow charging and other ways. The slow charging power is low, the charging time is long, and it is suitable for charging when the driving stops for a long time; Fast charging power is high, charging time is short, suitable for temporary emergency recharge. If there are slow charging conditions, try to choose slow charging as the main. If there is no slow charge condition, it is recommended to slow charge at least once a month to balance.
1, the charging speed is slightly slower Wireless charging slow charge fast charge : Compared with the wired charging bank wireless charging slow charge fast charge , even with fast charge wireless charging slow charge fast charge , the charging speed of the wireless charging bank will be slightly slower wireless charging slow charge fast charge , especially for devices with large capacity batteries, the charging time is longer. Compatibility limitations: Wireless charging bank requires devices to support Qi or other wireless charging standards, and devices that do not support wireless charging technology cannot enjoy its convenience.
2, Apple cable charge well. The advantage of magnetic magnet is that close to adsorption, adsorption can be charged, the charger automatically aligns the position of the charging coil, to solve the problem of wireless charging slow charge fast charge traditional wireless charging requires manual alignment; But it is still a wired form, and the power is not as good as wired charging, soTo the critical moment or wired charging is more realistic. If the MagSafe magnetic charger wants to turn into a regular one, it will depend on when the iPhone removes the charging port.
3, cable charging is good. In the case of the same charging time, the power of the commonly used wired battery charger is 93% after charging, and the power of the wireless charger is 88% after charging. Obviously, there is still a gap in the charging efficiency of wireless chargers, and there is still room for further improvement in technology.
4, the second kind of wireless charging, its working principle is the most used electromagnetic induction, wireless charging less line bondage, each time
