Wireless charging Qi certification test content includes: Compliance test (Compliance test) and compatibility test (InteropeIt is convenient to show pff to prompt the user to charge.
Use the wireless charging aging test fixture to test the wireless charging area on the left side of the product and show "PFF", that is, 5W mode PASS, 5W and 10W mode fail, the product supports ordinary 5W, not Apple 5W and Samsung 10W. When charging the iPhone wireless, although the Apple 5W fast charge is not supported, it can also be used for ordinary wireless charging in 5W (BPP) mode.
This PFF vehicle is the product of the height reduction of the modern specification of the outer space launch pad, breaking the Galileo andThe trend toward increasingly complex and expensive probes like Cassini. An article written by the designer about PFF appeared in the September and October 1994 issue of The Planetary Report, a bimonthly newsletter from the planetary research community. How much money will be needed for the project is uncertain.
1, the principle of wireless reverse charging is to use the power of the device itself to charge other devices. Some smartphones and other devices have reverse charging capabilities.Wireless charge conversion test , which allows them to use their own power to charge other devices. For example, if you have a mobile phone that supports wireless reverse charging, you can put another device on the back of it and let it draw power from the phone's battery.
2, wireless reverse charging refers to the wireless charge conversion test : the mobile phone as a wireless charging base, to support wireless chargingElectrical devices (such as wireless charge conversion test : watches, wristbands, mobile phones, etc.) are charged. Wireless reverse charging technology, derived from radio energy transmission technology, can be divided into low-power wireless charging and high-power wireless charging two ways. Low-power wireless charging often uses electromagnetic induction, such as the Qi method of charging mobile phones, but ZTE's electric vehicle wireless charging method uses induction.
3, wireless reverse charging means: the mobile phone as a mobile power to charge other devices, first with OTG line plus mobile phone data line to connect the two mobile phones,Then change the USB connection mode in the notification bar to reverse charging on the phone of the power supply side. Here, there is a premise that the phone of the power supply side supports OTG. If the other phone does not support reverse charging, the supporting end will automatically supply power.
1, different, the wireless charger will have a loss when charging, 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 chargesAppliances, but the result is 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.
2, different. Moreover, according to different wireless charger manufacturers now, the current and frequency are not the same. (The students themselves bought one online, it is said that the speed is relatively fast. The way to make it is to connect the metal pole of the wireless charger receiving device to the metal sheet of the charging electrode of your own phone, and then drag the wire outside to receive from the outside.) The fever is due to the high current in the charger, which leads toObvious fever. 3, charging speed may be limited Although many wireless chargers have achieved fast charging, in some cases, their charging speed may still not be as fast as traditional wired charging methods. Especially in the case of low power and the need for fast charging, wireless charging may not meet the needs of users. Higher cost Compared to wired chargers, wireless chargers are usually more expensive.
4, Hello! Using the original charger is faster, and wireless charging is slower.
First is a wireless charging pad for testing wireless charge conversion test , it needs to be able to support all wireless charge conversion test mainstream charging protocols, Examples include Qi, AirFuel, and PMA. In addition, an ammeter is required, and its main function is to test the current consumed by the wireless charging pad when charging. When we run the test, we need toDecide which phone you want to test.
Therefore, in the test must consider the charger, interface line and battery three aspects of the match, in order to ensure the accuracy of the charging efficiency. Then, through a test device with a charge control chip, the fast charge efficiency of different mobile phones is evaluated by wireless charge conversion test . Test equipment will record the battery voltage, current, charging time, charging speed and other key data of each mobile phone, and then comprehensively calculate the charging efficiency of each mobile phone.
First, the machine evaluates the phone's batteryThe loss test is done by simulating the user usage scenario. Testers will use the phone for a certain period of time for different operations, including music, video, games, etc., to test the wear and tear of the phone in different scenarios. At the same time, it is also necessary to consider various network environments, such as 4G, 5G, WIFI, etc., in order to test the battery consumption under different networks.
In the horizontal evaluation, we use the following three methods to evaluate. Standby test Standby test is one of the most basic tests to evaluate the performance of a mobile phone battery. The test requires the phone to constantly turn on the screen and conduct various application tests to measure the phonePerformance of power management, such as standby time, battery consumption, etc. For the standby test, we used a test program during the test and set the brightness of the phone to the same standard value.
The answer is that you need to pass the test. Machine horizontal evaluation is specialized in a variety of testing institutions, the agency through the mobile phone's level is strictly tested, and finally obtained whether the level is accurate.
1, in the wireless charging efficiency test, IWe need several major tools and equipment. The first is a wireless charging pad for testing, which needs to be able to support all the major charging protocols, such as Qi, AirFuel, and PMA. In addition, an ammeter is required, and its main function is to test the current consumed by the wireless charging pad when charging. When testing, we need to first decide which phone to test.
2, you first look at the power of the charger is how much W, how much output current is, and then how much mah cell phone battery capacity, capacity = current * time, see the theoretical charging time and the actual chargingHow much difference between, you can get a rough idea of efficiency.
3. In order to simulate the real use environment, we use Apple iPhone 13 Pro and Huawei P50 Pro as fixed test machines. During the test, the power of the two mobile phones is first exhausted, and then they are respectively placed on the wireless charging board of the car for 15 minutes to test their charging efficiency. After charging, the back of the two phones was measured with an infrared thermometer to test the heat generated by the body.
4, plug the wireless charger into the power supply, and check whether the wireless charger is working properly. Such asIf the wireless charger does not work properly, you can try to replace the charger or check whether the cable of the charger is damaged. Place your iPhone on a wireless charger and watch to see if it starts charging. If the phone does not start charging, you can try adjusting the position of the phone or repositioning the phone. Check whether wireless charging is enabled on your phone.
