This article gives you a talk about millet wireless car charging a power abnormal sound, and millet wireless car charging does not enter the corresponding knowledge points, I hope to help you, do not forget to collect this site. < / p > < h2 > the article directory list: < / h2 > < ul > < li style = 'margin - bottom: 3 px; list-style: none'>1, Millet balance car charging always ring
1, flat and balanced car charging drops ring, I think it is likely that your charging car may be broken, and sometimes broken, it may be this kind of thing may drop ring.
2, electric vehicle charging sound is due to the charger cooling fan lack of oil or broken leaf caused. Find the problem. Car abnormal sound this problem, the average owner is veryIf it can be your charging car, it may be broken, and sometimes if it is broken, it may be this kind of thing, it may drop.
The sound of electric vehicle charging is caused by the lack of oil or broken blades of the charger cooling fan. Find the problem. Car abnormal sound This problem, ordinary owners are difficult to distinguish which is the fault abnormal sound, which is reasonable abnormal sound. To the repair shop to detect the abnormal sound of the vehicle, only nearly 20% of the car really out of the problem.
One is that the charger is broken, the second is that the charging interface in the balance car is in poor contact, and the third is that the battery is aging. Correctly distinguish between normal and abnormal soundsOften sound. The vibration of the various organs of the car at work will make a variety of sounds, but the sound does not mean that the car is faulty, in order to avoid unnecessary disassembly, we must first distinguish between normal and abnormal sounds.
1, millet charger. If it is wireless charging, sometimes he has some sound is very normal, so do not worry about this is also a normal phenomenon when he charges. If the sound is larger, you can go to the millet after-sales service to consult and checkOne moment.
2, the circuit is designed with a switching power supply, in which the switching transformer will make a squeaking noise, which is the sound of the magnetic core is not tight and the oscillation frequency is higher. It's a transformer. They all make sounds just big and small. The squeak emitted by the high-frequency transformer is not loud and has no effect on the circuit and can be ignored.
3, the charging treasure emits a sizzling sound is the low-frequency clutter generated in the switching power supply, which is heard by the human ear through the inductor core vibration. Normal switching power supply design will try to avoid such a situation, hear such a sound is a product flawDefects generally do not affect use. As Xiaomi is a big brand, the chance of such a mistake is not high. There are many imitation products of Xiaomi charging treasure on the market, and the quality is naturally less than the original products.
4, this is a quality problem, indicating that the quality is not good, and the charging treasure is also the same voltage as the mobile phone battery. There is a DC_DC circuit inside to boost the 5 volt voltage so that it can be filled with useful products. Generally, the load current of poor quality is different, and the sound is different.
5, squeak, is the sound of the rectifier element, normal. Xiaomi mobile power uses LG/ Samsung's top lithium-ion battery cellTexas Instruments' latest USB intelligent control chip and charge and discharge chip. Due to the use of the latest USB intelligent control chip and charge and discharge chip of Texas Instruments, this mobile power supply has multiple protection functions, such as temperature protection, short circuit protection, input overvoltage protection, input anti-reverse protection and so on.
6, poor contact: the plug of the charging treasure is not strictly in contact with the power socket, causing the virtual connection to squeak. Poor inductance quality: the changing current flowing through the inductance coil will have the effect of electromagnetic force, and if the inductance quality is poor, it will emit an obvious high-frequency sound, which does not affect the use of the sound.
2, electric vehicle charging sound is due to the charger cooling fan lack of oil orCaused by broken leaves. Find the problem. Car abnormal sound This problem, ordinary owners are difficult to distinguish which is the fault abnormal sound, which is reasonable abnormal sound. To the repair shop to detect the abnormal sound of the vehicle, only nearly 20% of the car really out of the problem.
3, millet balance car charging has been ringing indicates that the internal circuit board short circuit, or there have been components damaged, the system issued an alarm, need to open inspection and processing. Charging is a Chinese term referring to the process of replenishing a device such as a battery. The principle is to let the direct current pass in the opposite direction of the discharge to restore the active substance in the battery. It has extended meanings like study, workLet's wait.
4, No. 9 balance car and No. 9 balance car Plus charging, there are five grid power ICONS in the battery box, each grid represents 20%. When it is full of 40%, two grids are steady on and three grids are blinking back and forth; When it is full of 60%, three grids are steady on, and two grids are blinking back and forth; When fully charged, the five cell ICONS flash back and forth together.
Millet wireless car charge a power with abnormal sound introduction to talk about it here, thank you for taking the time to read the content of this site, more about millet wireless car charge does not enter the electricity, millet wireless car charge a power with abnormal sound information do not forget to find in this site.
