Today to share the knowledge of wireless charging short circuit test, which will also explain the wireless charger tester, if you happen to solve the problem you are now facing, don't forget to pay attention to the site, now start!
< ul>Wireless charging coil test good or bad method is as follows: test the resistance value of the coil, resistance value within a certain range is a good product. Test the Q value of the coil, the higher the Q value, the better the performance. Test the coil temperature rise, the lower the temperature rise, the better the performance. Test the efficiency of the coil, the higher the efficiency, the better the performance.
The secondary winding is broken, the wireless charging coil has two windings, one is the main winding, one is the secondary winding, after the secondary winding is damaged, it will cause the main winding to heat, and the output has no voltage.
In order to simulate the real use environment, we use Apple iPhone 13 Pro andHuawei P50 Pro two mobile phones 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.
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 equipmentWill record the battery voltage, current, charging time, charging speed and other key data of each phone, and then comprehensively calculate the charging efficiency of each phone.
Plug the wireless charger into the power supply and check that the wireless 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.
If your mobile phone cannot use wireless charging, please follow the following steps: Check whether the mobile phone is overheating, it is recommended to charge in a good heat dissipation environment. Check whether the wireless charger indicator light is on normally, and check whether the connection between the charging base, data cable, charger, and power supply is in poor contactRe-insert.
Different brands of models due to the difference in coil position, may lead to low charging efficiency or can not be charged, please put the mobile phone wireless charging area correctly in the wireless charger induction area to try. Please do not use too thick or magnetic insulation material/metal material case, these cases may affect the charging efficiency or can not be charged, or even overheating to cause the phone can not be charged or damaged.
Replace the wireless charger: When our mobile phone has such a situation, it is likely that we have a problem with the charger, at this time we can replace a wireless charger to try (original wireless charger)Or usb data cable) restore factory Settings: if the fault is still on after the boot, we can try to restore factory Settings on the phone at this time.
Apple 12 wireless charging does not work for the following reasons: Buying and using a wireless charger is not compatible. A charger that supports the Qi wireless charging standard is required for wireless charging. Make sure the charger is working properly and meets the wireless charging requirements of the Apple 12. There is a physical barrier between the wireless charger and the iPhone 12.
1, in the case of power failure, measure the European Union gear, the red and black probe measures the live line and the ground line, the meter becomes low resistance, that is, short circuit. Second, in the case of electricity, the voltage block and the red and black probe are used to measure the fire line and the ground line, and the meter becomes zero voltage, that is, the open circuit. In the case of power, the voltage block and the red and black probe are used to measure the live line and the ground line, and the meter has voltage, that is, ground. The meter has no voltage, which means it is not grounded.
2, check the plug-in and plug to ensure that the connection is normal. Installation Tips When installing the detector, remember to connect at least 3 meters of detection cable and set it up in the airAnd keep a 20cm distance from the ground or wall. This can avoid the detector empty and false alarm. Blinking yellow If the detector is blinking yellow, the detection cable may be short-circuited with the housing or ground wire. Check the feeder heads and connectors to make sure they are connected properly.
3, the abnormal increase in the current in the line may mean that there is a short circuit or ground fault. The fault indicator can immediately alarm when the current exceeds the preset threshold, so that you can detect the hidden trouble in advance. This article will introduce the working principle and characteristics of the two fault indicators to help you choose the right product. Overcurrent principle The fault indicator using the overcurrent principle can be preciseQuasi-monitoring of short circuits and ground faults. It immediately alarms when the current exceeds the preset threshold, so that you can find hidden dangers in advance.
4, first turn off the power supply, use the resistance of the multimeter to measure the on-off line, such as zero resistance, that is, short circuit; If the resistance is infinite, the circuit is broken. Then send the power supply, use the voltage file of the multimeter to measure the voltage of the electrical appliance, if there is 220V, it is normal; There is no voltage between the metal shell of the electrical appliance and the ground wire, and if there is, it is leakage. Short circuit, its resistance is basically zero, with a multimeter resistance can be measured. Disconnect the circuit when measuring.
5, this article will focus on the introductionThese two provisions help readers better understand the design and implementation of grounding systems. In an effective grounding system, the grounding conductors (wires) of electrical installations in power plants and substations must undergo rigorous thermal stability checks to ensure safe operation under the current of a grounding fault (short circuit).
There is a problem with the charger or charging cable, there is a problem with the phone battery. There is a problem with the charger or charging cable: Make sure you are using an Apple certified charger and charging cable and check itCheck for damage or wear. Mobile phone battery problems: Mobile phone battery has been aging or damaged, will also cause wireless charging can not work properly, the battery needs to be replaced.
Apple 12 wireless charging does not work for the following reasons: Buying and using a wireless charger is not compatible. A charger that supports the Qi wireless charging standard is required for wireless charging. Make sure the charger is working properly and meets the wireless charging requirements of the Apple 12. There is a physical barrier between the wireless charger and the iPhone 12.
The reasons for the failure of the Apple 15 wireless charging may be as follows: The device is not aligned to chargeA surname If the device is not properly placed in the center of the charger, or there is a physical barrier, it may cause charging failure. The charger is not connected to power. Make sure the wireless charger is plugged into the power adapter and connected to the power supply. The power adapter is faulty. If the power adapter fails, it may affect the work of the wireless charger.
1, recently, Green Link launched a popular desktop wireless charger (modelCD186), Apple Android general, support 5W and Apple 5W, Samsung 10W wireless fast charge, the key is that the price is only 49 yuan, cost-effective can be said to crush the market similar 99 yuan products. In order to understand the workmanship of this product, the next thing to bring you is its unpacking.
