Advantages of wireless charging: one: reduce loss. It is well known to use wireless chargingYou only need to connect the wireless charging board to the power supply first, and then place the device that supports wireless charging on the wireless charging board. Although wireless charging still needs to be connected to the power supply, it can reduce the use of data lines and avoid a large amount of loss and waste of data lines, which is relatively an environmentally friendly charging method. Two: high adaptation rate.
The advantages of wireless charging are: reduce loss, high adaptation rate, the disadvantages are: the distance is too small, but the transition technology; Charging can not play with the mobile phone, etc., the specific content is as follows: The benefits of wireless charging reduce loss as we all know when using wireless charging, you only need to connect the wireless charging board firstPower supply, and then place the device that supports wireless charging on the wireless charging board.
Mobile phone wireless charging has the advantages of convenience, flexibility, and protection interface, and the disadvantages are low charging efficiency, slow charging speed, and high cost. Benefits Convenience: Wireless charging of mobile phones eliminates the hassle of using a charging cable. Users only need to place the phone on the charging dock, without plugging or unplugging the charging cable, to start charging. This makes the charging process easier and faster. Flexibility: Wireless charging eliminates the need for a specific charging cable.
The advantages and disadvantages of wireless charging are as follows: Advantages: Wireless charging can reduce wired chargingWhen the plug plug, thereby extending the service life of the mobile phone charging interface; Wireless charging technology is suitable for a variety of device types; Wireless charging enables a cleaner, cleaner device appearance, eliminating the clutter of traditional cables.
Advantages and disadvantages of wireless charging of mobile phones: Benefits: Lightning cable wear reduction On the other hand, the popularity of wireless charging of iphones will reduce the use of cables. The wear on the cable will be reduced to almost zero.
System: The disadvantages of iOS 10 wireless charging are: low efficiency: the efficiency of energy storage and transmission is less than real contact. Slow charging speed: due to effectLow rate, under the same input power, the charging speed is slow. Although wireless charging can be unplugged, the distance between the phone and the charger is very small. However, the electromagnetic energy loss is still not small, and the power received by the general mobile phone is about 75% of the power sent by the charger.
1, increase the output, you can select materials from the equipment, choose a good electromagnetic coil. Because the transmitter and receiver of wireless charging are covered with wireless charging coils, the coils will have losses when working, and good materials will be usedQuality can reduce coil loss, which can greatly improve the efficiency of wireless charging. In terms of loss reduction, you can optimize the line and component selection to deal with. Streamline and optimize the line, and select good materials for components to reduce output losses.
2, wireless charger charging speed is slow, there are the following possibilities: 1, wireless charger wireless charging power itself is not large. 2, the wireless charging receiver of the mobile phone, the charging current supported is not large. It is recommended to change a high-power wireless charging board, such as a certain meter, which has more than ten coils, although it is not opened at the same time, the effect will be good.
3, if the user bought wirelessThe charger is a wireless fast charger, then the charging head may not be used, such as the charging head power is relatively small, so the charging speed is relatively slow. If the user is the use of a matching charging head, but also the use of wireless fast charging appliances, when charging does not show fast charging, you can shut down the phone and restart it, and then re-charge to try, generally can solve the problem.
4, the loss of components affects the internal resistance of wireless charging fast and slow components, and the conversion efficiency of the system is high. The selection of components such as triode with small internal resistance can greatly improve the efficiency of wireless charging. But the internal resistance is lowThe cost will be relatively high.
5, low charging efficiency Since it is for mobile phone charging, charging speed is of course the first, even if you can do the application of "wireless", but for the most basic requirements of charging speed can not be reached, then the experience will probably be a discount.
1, wireless charger charging speed is slow, there are the following possibilities: 1, wireless charger wireless charging power itself is not large. 2. Cell phoneWireless charging receiver, support charging current is not large. It is recommended to change a high-power wireless charging board, such as a certain meter, which has more than ten coils, although it is not opened at the same time, the effect will be good.
2, low charging efficiency: compared with wired charging, wireless charging efficiency is low. That means it takes longer for users to fully charge. In addition, since wireless charging requires energy conversion between transmit and receive, it may lead to reduced battery life. Slow charging speed: Due to the low efficiency of wireless charging, the charging speed is relatively slow. This makes it take longer for users to finishTo charge.
3, low charging efficiency Since it is for mobile phone charging, charging speed is of course the first, even if you can do the application of "wireless", but for the most basic requirements of charging speed can not be reached, then the experience will probably be a discount.
4, wireless charging than wired charging more damage to the battery. In fact, we all know that as long as it is charged, it will cause damage to the battery, but wireless charging and wired charging are compared, wireless charging will cause more damage to the battery, because wireless charging will generate more heat, and the heat generated will cause more damage to the batteryThe use of good materials can reduce coil loss, which can greatly improve the efficiency of wireless charging. In terms of loss reduction, you can optimize the line and component selection to deal with. Streamline and optimize the line, and select good materials for components to reduce output losses.
First replace the charger or test with another device to ensure that the charger can work properly, and be careful not to place anything between the iPhone and the charger. If the iPhone does not charge or charges slowly, and the iPhone has a thick protective case, metal protective case, or battery case, remove the protective case or battery firstShell.
Here's how to make sure charging works as well as possible: Place the charger on a flat surface. Make sure there are no metal objects nearby. Use a USB-C charger with at least 12 watts, preferably 20 watts or higher. Remove thick covers, especially if they contain metal parts. If you still want to use a case, select one that contains MagSafe magnets.
For example: 99 yuan millet wireless charger is 20W, then the choice of power plug is best not less than 20W, otherwise it will be discounted from the power plug. ifThe 20W Xiaomi wireless charger is equipped with a 5W Apple original power plug to wireless charge the iPhone with 5W wireless charging receiving power, so the final charging power is only 5W.
The reasons for the slow wireless charging of mobile phones in new energy vehicles are as follows: The reason for the external charger, the 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. handThe cause of the battery, the balance of the battery and the temperature will affect the speed of charging.
【 Pacific Auto network 】 Song pro wireless charging is not charged in the reason: the vehicle does not turn on the wireless charging function. The fuse for wireless charging is blown. The phone is not positioned correctly. Song pro wireless charging support Apple, BYD Song Pro is an SUV owned by BYD, BYD Song pro length, width and height are 4650 mm, 1860 mm, 1700 mm, wheelbase is 2712 mm.
Whether the vehicle configuration has a mobile phone wireless charging module, because the same modelCars come in multiple configurations, so you need to understand the configuration of your car. Mobile phone with wireless charging function, the market mobile phone configuration is uneven, to use wireless charging must be mobile phone with wireless charging function. If the above two are met, you need to charge your car after the power, and then the mobile phone with wireless charging function is placed in the charging area, then it enters the charging state.
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. Wouldn't it be interesting to use this technology in our new energy vehicles? Recently, the National Standards Management Committee issued four national standards on wireless charging of electric vehicles.
Wireless fast charge is neither fast nor slow. Wireless fast charge is much faster than wireless fast charge, and slower than wired fast charge. 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 over 2 hours wirelessly fastCharging, not as fast as the wired fast charge for 1 hour and 30 minutes, is not a fast charge. Unexpectedly, the wireless fast charging efficiency of 60% when the 18W is charged for 2 and a half hours.
Different, the wireless charger will have a loss when charging, and the loss is between 30-40 percent. So the ordinary charger is faster than the wireless charger. There are already fast chargers and fast wireless chargers, but the results are the same. For example, the fast charging Samsung S8 takes 90 minutes, then the fast wireless charger takes 190 minutes, which is the result of my own actual testing.
In addition to convenient advantages, noneThe disadvantages of line charging are many. For example, the charging time is too slow, Samsung Note 5 fully charged at least 6 hours or so; If you use a fast charge, it will be full in a little more than 2 hours. Although wireless charging also supports fast charging now, it is still not as fast as wired charging, after all, wired charging already supports 40W fast charging, and wireless fast charging is only 15W.
Wireless charging has the requirement of the distance between the mobile phone and the wireless charging panel, so a very thick mobile phone protective case or back bracket will cause the distance to exceed the effective receiving range or "virtual charging" phenomenon. Thickness distance/charging Angle/metal barrier, will be on the wireless charging bodyIt makes a big difference.
If the cross-brand change to Huawei mobile phone, Apple mobile phone, this wireless charger may not make much sense, or slow charging or incompatible, charging stability and charging efficiency are greatly reduced, and some will damage the mobile phone battery. So weigh, wireless charging start value is not high.
Because now the mobile phone has fast charging, compared with the wireless charging speed is relatively slow, so the mobile phone manufacturers do not blow wireless charging, hear less and feel that it is not popular. In fact, now high-end models are wireless charging as standard, there are also many cars with no factoryLine charging. The main reason is that the wireless charging current is too small. Wireless charging is limited to material problems and technical problems resulting in low efficiency.
