Today to share the knowledge of large coil car wireless charging, which will also explain the wireless charging coil winding equipment, if you happen to solve the problem you are now facing, don't forget to pay attention to the site, start now!
< ul>Same size. The same size and as close as possible, otherwise it will have no effect, low conversion efficiency.
According to the principles of physics, the stronger the electromagnetic coil, the stronger the magnetic field emitted, and then the reception of the mobile phone is also related, the stronger the magnetic field, the stronger the charging ability will be.
iphone8 has been rumored to have wireless charging function, and then the folk exposed the design drawings, the pattern drawn above, the middle of the iphone a large oval line diagram, is suspected to be used to support wireless charging electromagnetic induction coil.
The thicker the copper strip of the same material, the larger the cross-sectional area, the smaller the resistance, the resistance R = ρL/S. ρ indicates electricityThe resistivity of the resistance is determined by its own nature, L indicates the length of the resistance, S indicates the cross-sectional area of the resistance) the thickness of the copper strip is good enough, too thick waste, too thin resistance is easy to burn.
Disadvantages of wireless charging efficiency is slightly lower: the general charger also has a transformer, but the wireless charging transformer composed of the transmitting coil and the receiving coil is limited in structure, and the energy transmission efficiency is theoretically slightly lower than that of the general charger. Slow charging speed: Due to the current mobile phone and other receiving devices, most limit the input power, so the charging speed is slow.
In terms of increasing output, materials can be selected from the equipmentThe rate is lower than that of wired charging. Inductive charging is more stringent for vehicle location. In addition, compared with the charging pile, the cost is higher, and the charging standards of various brands are different.
Advantages: convenient. Just put the phone in the designated position of the car, you can wireless charging, no need to use the data cable to connect the phone and the car, it is very convenient to use. Good compatibility. The use of data cable charging needs to choose the appropriate cable according to the mobile phone charging port, such as type-c and Apple data cable, and wireless charging does not need to distinguish, can be unlimited compatible. Cons: Slow charging speed.
Wired charging and wirelessThe advantages and disadvantages of wired charging are fast charging speed, good stability, and data transmission can also be carried out at the same time. The disadvantage is that the connection line is required and the use is not convenient enough. The advantage of wireless charging is that it is easy to use, does not require a cable, and only needs to put the device on the charging base to charge. The disadvantage is that the charging speed is slow, the charging efficiency is also low, and the device needs to be placed on the charging base, which is not flexible enough.
This wireless charging technology is superior to electromagnetic induction wireless charging technology, which not only extends the transmission distance, but also does not require the position between the coils to be completely consistent. In addition to the two wireless charging technologies mentioned above, there areElectric field coupling wireless charging technology, microwave resonance wireless charging technology. Although wireless charging technology has some years of development, many problems restrict its universal application. Wireless charging opens up a new charging mode for smart phones, getting rid of the shackles of traditional charging data cables.
Nowadays, many mobile phones that support wireless charging are electromagnetic induction, and the advantage of this inductive charging is that the energy conversion rate is high. However, for the wireless charging system, the charging efficiency is directly related to the distance between the transmitting coil and the receiving coil, the position deviation, etc. Once the position of the two coils is slightly wrong,It will seriously affect the efficiency of wireless charging, and can only achieve one-to-one charging.
Electric vehicle wireless charging technology has become a hot electric vehicle to become the mainstream, the problem of battery life has not stopped, in order to solve the battery life problem, the various car companies have also tried their best to find a way to solve this problem, in addition to the power change and fast charge, in fact, there is a different way, that is, road charging, Let the car run along the road.
TeslaThe logic behind the wireless charging technology applied by Germany's WIFERION in the modified Model 3 is electromagnetic induction wireless charging. At present, the modified Tesla Model 3 can achieve a maximum of 12KW wireless charging power, the fastest one hour to make up 80 kilometers, full may take about 6 hours.
The wireless charging process will definitely heat up. As long as the temperature is not very high, no problem, you see if there is something around the block, because many times love to put some things on it. Low-power wireless charging often uses electromagnetic induction, such as onThe Qi method of mobile phone charging, but ZTE's electric vehicle wireless charging method uses induction.
In general, the car wireless mobile phone holder for its practicality and canIt provides a safer mobile phone use environment for drivers. If you are looking for a stable and convenient mobile phone mount solution, choosing a car mount with wireless charging function is undoubtedly a wise choice, which will effectively enhance the driving experience and reduce the distractions of driving.
If you want to try the voice control function, and there is no need for charging speed, 360 is a good cost-effective choice; Although the price is the cheapest, but no electric clamp arm is relatively big hard injury, after all, lose this function, you may not need to buy a wireless charging mobile phone holder, it is better to see the ordinaryThe stent is cost-effective, and it is much better to increase the budget to buy the experience.
For the iPhone X used by the author, it is also very useful to equip the car with a mobile phone stand with wireless charging, and the two-in-one function is more classy than the original.
What are the requirements of the mobile phone wireless charging bracket The mobile phone needs to support wireless charging First of all, it needs the mobile phone to support wireless charging, if the mobile phone does not support the function, then the connection will not be charged, can only be used as a bracket. At present, the main flagship models are supported by this feature, but there are stillA few do not.
Slow charging speed. Wireless charging, while convenient, is relatively slow because it can only receive electrical energy through an electromagnetic field within the coil. The base tends to heat up. In the process of wireless charging, due to certain losses, the charging position may be hot, which may bring security risks in serious cases.
The advantage of automobile wireless charging technology is that electric vehicle wireless charging has no exposed connector, which can adapt to a variety of harsh environments and weatherAvoid leakage, electricity and other safety hazards. The disadvantage is that the power is small, it can only be slowly charged, and the transmission efficiency is lower than that of wired charging. Inductive charging is more stringent for vehicle location. In addition, compared with the charging pile, the cost is higher, and the charging standards of various brands are different.
has an effect. The car wireless charging bracket may affect the compass function of the phone, navigation accuracy, battery life, etc., so it is sure to have an impact on the phone, but the impact can be large or small. If the magnetic adsorption is used, the impact may be larger, but if the ordinary physical structure is used, the impact is less.
Slow charging speed: Due to the current mobile phone and other receiving devices, most limit the input power, so the charging speed is slow. High cost: The charger needs to have an electronic circuit to push the coil, and the electrical device needs to have an electronic device to convert power, both also need to have a coil, and need a high-frequency filter circuit to meet FCC and other specifications, so the cost is higher than direct contact.
If the car charger is not compatible with your mobile phone, it will not be charged, and the charging current will be small. If compatible, the car charger quality is too poor, the output current is too small, the charging effect is not obvious, will feel noCharge it. Your car wireless charging is faulty, and there may be some problems with your phone's battery.
