1, does the question want to ask "How many Hertz is the wireless charging frequency of mobile phones in Germany"? 100-145kHz, 6765~6795kHz, 13553~13567kHz. The use frequency of mobile and portable wireless charging equipment is 100~145kHz, 6765~6795kHz, 13553~13567kHz, and the rated transmission power is required to be less than 50W.
2, wireless charging, using the principle of electromagnetic induction, the working frequency is very low, and the risk is small. If you're still worried, you can choose and defend your plan.
3, w. At present, domestic mobile phones have supported 50W wireless charging, and 50W is also wireless chargingThe upper limit of the provisional standard, but even so, the frequency of use of wireless chargers is still not as good as the traditional charger, and Samsung launched a 15W wireless charger at this time, which is really confusing.
4, in order to effectively reduce the adverse effects of electromagnetic radiation on health. For mobile phones: under normal circumstances, it will not harm the mobile phone, and the working frequency of wireless charging is now below 1M, so it will not affect the signal of the mobile phone. Wireless charging has no effect on mobile phone battery life, and wired charging is basically the same, but the rate is lower, but the wireless charger conversion rate is still very high, more savingEnergy consumption.
5, wireless charging, and even remote sensing charging. Its principle is electromagnetic induction, which is usually used in small power situations and does not require electrode contact points. There are induction coils in the small column and electricity, there are induction coils in the electric toothbrush insertion part, and there are plastic insulation outside, there is no electrical contact, and the induction obtains electricity to charge the battery and drive the small motor.
6, because the current working frequency of wireless charging is less than 1M, it will not affect the signal of the mobile phone. On the contrary, wireless chargers not only reduce the use of data lines, but also make charging methods more free and more securep>
For example, Tesla models turn on FSD to automatically recharge the vehicle after arriving at the destination; Unmanned buses, express vehicles, etc., can also be completely unmanned management; Or you do not have time to find a charging pile for your car, you can send the vehicle to find its own wireless charging pile "foraging"; Wireless charging can also solve the problem that many vehicle charging plugs are not shared at present, just like mobile phones, cars, SUVs, trucks, etcVehicles of the same type and different brands can be charged using the same charging pad.
First of all, Tesla's wireless charging technology uses the principle of electromagnetic induction. The technology transmits energy through special electromagnetic fields, allowing Tesla cars to charge themselves when parked. This technology is not only efficient, but can also greatly reduce charging time. Secondly, the wireless charging technology of Tesla cars also has the characteristics of intelligence.
According to media reports, Tesla recently launched a $300 "wireless charging platform" that can charge up to three devices simultaneously. This is wireless chargingThe pad can provide up to 15 watts of charging power for each device that supports the Qi wireless charging protocol, including iPhone, Android or AirPods headphones. According to Tesla's official website, the charging pad has been opened for pre-sale and will begin shipping in February 2023.1, suggestion: reduce the charging current, is the voltage normal; Put the receiving coil against emissionThe coil is closer; Re-match the circuit of the transceiver coil, it is best to test whether the two ends are the same frequency; Consider redesigning the coil.
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 bought to the metal sheet of the charging electrode of your own phone, and then connect the wireDrag it outside and receive it from outside. The heat is caused by the large current in the charger, which leads to obvious heat.
Hello! Using the original charger is faster, and wireless charging is slower.
Low charging efficiency Since it is for mobile phone charging, the speed of charging is of course the first, even if you can do "wireless" in the application way, but for the most basic requirements of charging speed can not be reached, then the experience will probably be a discount.
The iPhone8 takes about 5 hours to charge with 5W, and nearly 4 hours with 5W. Xiaomi MIX2s has been evaluatedAfter a little more than 3 hours full, the actual charging power is about 8W, and the speed of wireless charging is actually improving. I know there is a micro goose compatible with Qi air wireless charge, iPhone8 as long as 2 and a half hours full, probably because it is different technology speed is faster, and this is not fast charge.
1, the relevant standards for wireless charging have not yet been introduced, and according to the specification documents of the wireless charging Alliance, the working frequency of wireless charging products is setIn theory, the level of electromagnetic radiation is comparable to that of ordinary small appliances, and this standard is lower than the electromagnetic field exposure limit for products exposed to the public promulgated by the International Commission on Non-Ionizing Radiation Protection (ICNIRP), which has been reviewed and approved by expert committees in more than 35 countries.
2, wireless charging, using the principle of electromagnetic induction, the working frequency is very low, and the risk is small. If you're still worried, you can choose and defend your plan.
3, wireless charging is usually not harmful to mobile phone batteries. Wireless charging channels electrical energy through electromagnetic inductionIt is converted into special energy and transferred between magnetic fields to achieve the charging of the mobile phone battery. This charging method does not require the use of data cables, making charging more convenient and safe. Under normal circumstances, wireless charging operates at a frequency below 1MHz and will not affect the phone's communication signal.
