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 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.
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.) feverBecause the current in the charger is large, resulting in obvious heating.
3, Hello! Using the original charger is faster, and wireless charging is slower.
4, slow charging speed: due to the low efficiency of wireless charging, the charging speed is relatively slow. This causes users to have to wait longer to complete the charge. High cost: Wireless charging technology is relatively new compared to wired charging technology, so its cost is higher. This also means that wireless chargers may cost more than wired chargers.
1, the amount of charging within minutes reaches or exceeds 10%, and the charging efficiency is even higher than the direct use of wireless chargers. In contrast, the Deep Blue SL0 Long comfortable Da and Wei brand Blue Mountain DHT-PHEV are obviously not too friendly for Apple iPhone 13 Pro, with a 15-minute charge of 3%, which is a large gap compared with other test models.
2, "Electric vehicle wireless charging system Part 2: Communication protocol between vehicle charger and charging equipment."(GB/T 38772)," Electric vehicle wireless charging system Part 3: Special requirements "(GB/T 38773)," Electric vehicle wireless charging system Part 4: electromagnetic environmental limits and test methods "(GB/T 38774) a total of 4 national standards.
3, the highest charging efficiency of Xiaomi and Huawei require the mobile phone to support their own protocols, so we separately tested the Huawei Mate 30 with Huawei wireless charging mobile phone bracket and Xiaomi 10 with Xiaomi wireless charging mobile phone bracket. The standard test uses iPhonThe e 11 pro comes with all wireless charging phone stands, and the rule is that the phone stays lit, and the time required to charge 10% (from 40% to 50% of the phone's battery) is tested on all products under test.
4, the storage space part, the performance of the two cars are quite satisfactory. Due to the design of the shield, there are a lot of storage space under the center console of the two cars. Xopeng P7 is equipped with the function of wireless charging of mobile phones, but Tesla reserves the USB charging port harness in the cover plate is more humane. If the wiring is directly connected in the armrest on Xopeng P7,Charging "?
The charging speed is slow, which is more than 2-3 times slower than the usual line charging speed. Stable wireless charging Here, the concept of "stable wireless charging" is proposed. In the test for the upcoming McGeek new energy disc, our engineers have carried out the maximum debugging of temperature control, power, continuity, etc. during the charging process, and strive to make the wireless charging experience the best.
Wireless charging methods include electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, etc. Wireless charging of mobile phones mostly uses the principle of electromagnetic induction. Electromagnetic induction type noneWire charging: When the current of the power supply passes through the coil (the power supply coil of the wireless charger), a magnetic field will be generated, and other unenergized coils (the electric coil of the mobile phone) will be close to the magnetic field, and the current will be generated to charge the mobile phone.
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, magical 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.
Advantages:The advantage of wireless chargers is that we can charge the phone while using it, no longer need to unplug the data cable. In addition, it can be taken at any time, which is more convenient than charging with a data cable. At the same time, it can provide certain support for the phone, making the phone charge more stable. Disadvantages: One disadvantage of wireless chargers is that the charging speed is relatively slow, and most wireless chargers only support 5W or 5W charging power.
If the vivo mobile phone is used, wireless charging is also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, the device that needs to be charged can be charged by contacting the wireless charger after being energized.
2, therefore, in the test must consider the charger,The matching of the interface line and the battery can 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.
3. First of all, the battery loss test of the mobile phone is completed by simulating the user's use scenario. Testers will use the phone for a certain period of time for different operations, including music, video, games, etc., to test the phoneWear and tear 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.
4. In the horizontal evaluation, we adopted the following three methods for evaluation. 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 keep the screen on and perform various application tests to measure the phone's power management performance, such as standby time and battery consumption. For the standby test, we used a test program during the test and set the brightness of the phone to phaseThe same standard value.
5. First of all, the machine horizontal evaluation adopts the practical use test method with strong targeting and strict test conditions to evaluate the battery life of various brands of mobile phones. The computer horizontal evaluation will use a mobile phone to simulate the actual use of the day, such as using the Internet, making phone calls, playing games, etc., so that the simulated use picture is closer to the reality and the data is more accurate. Secondly, the computer horizontal evaluation also uses professional measuring tools, such as electricity meters, radiometers, etc., to measure the battery life of the mobile phone.
