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. Next, the fast charging efficiency of different mobile phones is evaluated through a test device with a charge control chip. 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.
The maximum charging efficiency of Xiaomi and Huawei requires the mobile phone to support its own protocol, so we separately tested the situation of Huawei Mate 30 with Huawei wireless charging mobile phone bracket and Xiaomi 10 with Xiaomi wireless charging mobile phone bracket. The standard test uses the iPhone 11 pro with all wireless charging phone stands, and the rule is to keep the phone lit, and test the time required to charge 10% (from 40% to 50% of the phone charge) on all products under test.
In the horizontal evaluation, we use the following three methods to evaluate. Standby test Standby testThe temperature control, power, continuity, etc. have been adjusted to the greatest extent, and strive to make the wireless charging experience the best.
2, wireless charging refers to the charger on the terminal device that needs to be charged without the traditional charging power cord, using the latest wireless charging technology, through the use of the magnetic field generated between the coils, the magic transmission of electrical energy, inductive coupling technology will become a bridge connecting the charging base station and equipment. How to use: Connect the USB cable and plug it into the socket.
3, wireless charging is also known as inductive charging, non-contact inductive charging, from wireless power transmission technologyThe technique is to use near-field induction, that is, inductive coupling, 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.
1. In the comparison of wireless charging functions, you can find the wireless charging test template , and 6 out of 10 models support manual closing of wireless charging functions Wireless charging test template , and Hao platinum GT also supports language closure, the overall performance is excellent. Slightly regrettably, the BMW Z Buick Veran Pro GS, Chery Arezer 8 and Tesla Model 3 do not support closing.
2, millet and Huawei's maximum charging efficiency need the mobile phone to support their own protocol, so we separately tested the wireless charging test template Huawei Mate 30 with Huawei wireless charging mobile phone bracket and Xiaomi 10 with Xiaomi wireless charging mobile phone bracketSituation. The standard test uses the iPhone 11 pro with all wireless charging phone stands, and the rule is to keep the phone lit, and test the time required to charge 10% (from 40% to 50% of the phone charge) on all products under test. 3, in summary, Keysight E4980A/AL precision LCR table with its high precision, wide impedance range, fast measurement and multi-fixture selection, has become the ideal choice for wireless charging system coil test, to ensure the high efficiency and high reliability of the system provides a strong support.
4, in performanceIn tests, the Lauco USB-C 12-in-1 hub performed reliably, with no problems with fast device insertion or wireless charging. Even when connected to multiple devices at the same time, such as monitors, external storage devices, ipads, iphones, MacBook chargers, it can stay calm and not overheat. This hub is undoubtedly the ideal choice for travel storage, replacing the traditional hub location.
5, Tesla test charging robot) Of course, wireless charging from the power point of view, the highest sample product is 22kW, and the supercharge is 10More than 0 kW compared to a lot slower wireless charge test template ; However, this does not prevent the practical convenience in many scenarios, such as when the vehicle is placed in the parking lot and when it is parked in the garage at home, the non-inductive effect brought by wireless charging can really make the vehicle charge "all the time", and is not worried about the "recharge" problem.
1, whether it is charging the iPhone13 with 15W full blood, or charging the iPhone13 with the actual speed of close to 5V1A, the machine is always in a warm state. The biggest killer of batteries is electricity, and this temperature is enough to cause damage to batteries. 2, Conclusion: Apple's official MagSafe wireless external battery, with the characteristics of small, portable and durable, became a wise choice for me to solve the power anxiety on business trips. I was pleased with the improved battery life after replacing the iPhone 13, but when it came to going out for a long time, IStart looking for a lightweight backup power source that can support MagSafe wireless charging. After screening, I finally chose the official external battery.
3, compared with the all-inclusive Pro version, MagEZ Case in the daily commute will have a more comfortable experience, feel relatively more thin, of course, if the habitual hand slider, it is still recommended to use the all-inclusive Pro model.
To summarizeSaid wireless charging test template , Keysight E4980A/AL precision LCR table with its high precision, wide impedance range, fast measurement and multi-fixture selection, Become the wireless charging test template Wireless charging test template The ideal choice for wireless charging system coil test Wireless charging test template provides strong support to ensure the high efficiency and high reliability of the system wireless charging test template .
Inductance under testThe resistance value of the device is zero, and there is a short-circuit fault inside it. The size of the DC resistance value of the inductor under test is directly related to the enamelled wire diameter and the number of coils wound. As long as the resistance value can be measured, it can be considered that the inductor under test is normal. Note: If you need to determine accurate inductance and resistance values, please use special inductance testing instruments such as: impedance tester, LCR tester, digital bridge, etc.
1, plug the wireless charger into the power supply, and check that noLine charger is working properly. If 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.
2, the most intuitive way is to use a wireless charger to try to know, generally can be used normally. Compared with wired charging, the biggest convenience of wireless charging is that you can charge your phone without using a data cable.
3, check whether the mobile phone supports wireless charging methods: check the mobile phone manual, check the mobile phone Settings, check the mobile phone appearance, official inquiries, third-party applications, etc. In the specification parameters of the manual, there will be a relevant introduction to wireless charging of mobile phones. If the phone supports wireless charging, it will be clearly explained in the manual. View Phone Settings In your phone's Settings, you can find options such as battery or wireless and networking.
4, the phone case is too thick will affect the mobile phone charging coil and wireless charger induction, resulting in normal charging. Therefore it is recommended to protect the mobile phoneAfter the shell is removed, use the wireless charger to charge; The charging coil area in the mobile phone is small, and if the mobile phone is placed incorrectly when wireless charging is used, it will also lead to normal charging. The wireless charging coil is located in the center of the back of the phone, and can be placed on the surface of the wireless charger according to the position.
