The logic behind the wireless charging technology applied by the German WIFERION, which was acquired by Tesla, 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.
For example, the FSD is enabled on the Tesla modelAutomatic recharge of vehicles behind the ground; 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 and other different types of different brands of vehicles can use the same charging plate.
First of all, Tesla's wireless charging technology uses the principle of electromagnetic induction. The technology transmits energy through special electromagnetic fields to keep Tesla cars in parkThe car charges automatically. 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 wireless charging 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, this charging pad has been opened for pre-sale, and will be available in 202The goods will be shipped in February, 2013.Magnetic resonance is an efficient and safe wireless charging method. It generates magnetic field resonance through the resonator to achieve efficient energy transmission. The advantages of this method include high efficiency, long distance transmission and security, but the technical requirements are high, the cost is relatively high, and it has not been applied on a large scale. In general, wireless charging technology is showing broad development prospects, is expected to become the mainstream of electric vehicle charging.
The charging process of the Tesla takes about 12 hours, but when using a home charger, the voltage may drop due to the transformer load peakThus affecting the charging speed. To increase efficiency, it is recommended to install a special wall-mounted charger, which will reduce the charging time to about 9 hours. The optional dual built-in charger can further shorten the charging cycle, and it only takes about 4 hours to full charge.
The basic principle of wireless charging is to convert the current into a magnetic field, which is transmitted through the air and then converted into a current to be transmitted to the intelligent terminal. When the system works, the input end converts the AC mains into direct current through the full bridge rectifier circuit, or uses 24V DCThe electrical end directly supplies power to the system. After passing through the power management module, the output direct current is converted into high-frequency alternating current through the 2M active crystal oscillator inverter to supply the primary winding.
Wireless charging system mainly adopts the principle of electromagnetic induction. Wireless charger refers to the charger that does not need to be connected to 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, the magic transmission of electrical energy, inductive coupling technology will become a bridge connecting the charging base station and equipment.
Wireless charging is also known as inductive charging or non-contact inductive charging, based on electromagnetic inductionThe technology of strong> wireless charge money principle , this fully shows our country's superb technology, so wireless charging can be done without data cable. With the improvement of science and technology, a variety of mobile phones are also more and more, there is a mobile phone charging method is very strange, is mobile phone wireless charging, wireless charging is the current into the magnetic field, the magnetic field through the air and then converted into current transmission to the charging device process.
Because it does not need to be in direct contact with the data line, it will not be eroded by water and oxygen, and mechanical grinding is directly avoided without contactDamage and tripping, so it is relatively safer than charging the data line.
In fact, it has to be said that the wireless charger does bid farewell to the bondage of the charger line, and it is precisely because of this that it becomes more convenient and convenient, so most people prefer this charging method.1, however, portable wifi needs to rely on the operator's mobile network, which requires users to recharge the data or order a monthly package. Package prices vary by brand and choice.For frequent users, monthly plans are often more economical; Users with occasional use or temporary needs can choose to recharge their data. There are various ways to recharge, which can be completed by App, recharge card or electronic payment.
2. The reason for charging money for portable wifi is that portable wifi needs to use the mobile network provided by the operator, so it needs to recharge the traffic or purchase a monthly package. Different package prices are different, in general, if the user needs to often use the portable wifi Internet access, then choose a monthly package will be more cost-effective, and for light users or temporary needs of users, chooseData top-up plans would be more appropriate.
3, first of all, users need to buy portable WiFi devices, the price of these devices may vary depending on the brand, features, performance and other factors. Some operators may offer rental services, but this usually requires a certain deposit or rent. Second, users need to pay a monthly fee or data fee. These fees depend on the plan and service provider chosen by the user.
4, portable WIFI needs to handle Internet traffic package, so to pay to the business hall, no traffic, you need to charge money.
5, portable wifiIt needs to be topped up because it relies on the carrier's mobile network services. Users can choose different top-up methods according to their needs. Some brands provide App recharge, just download the corresponding App, select the package or enter personal information to complete; Some brands support the purchase of prepaid cards or through online payment methods such as Alipay and wechat.
Confirm whether the mobile phone is hot charging speed and mobile phone state has a greater relationship, charging if the mobile phone temperature is high, comprehensive charging bodyTest, security, equipment life and other multiple factors, the actual charging power will be adjusted intelligently, at this time the charging will be slow, please try to avoid charging while running high-power software, such as playing games, brushing short videos, live broadcasting and so on.
During the charging process, the temperature of the phone will change to a certain extent, especially when the phone is charging, it also runs some high-power programs, which will make the temperature rise significantly, which will lead to slow charging. In summer, the weather is hot, the ambient temperature is high, and the heat dissipation of the mobile phone is difficult, so the charging speed will be relatively slow compared with the winter when the ambient temperature is low, which is a normal phenomenon. It is recommended that you try to charge your phone at room temperature,It is recommended to close high-power applications running in the background during charging.
If you use vivo mobile phone, the temperature of the mobile phone will affect the charging time; Low temperature will affect the activity of lithium electrons, resulting in a slowing down of the charging speed, but also affect the normal standby time of the equipment; Charging in a high temperature environment will affect the heat dissipation of the device, and higher temperatures are unfavorable to the battery and will also affect the charging speed.

1, wireless charging is usually not harmful to mobile phone batteries. Wireless charging converts electrical energy into special energy through electromagnetic induction and transfers it between magnetic fields to achieve charging of mobile phone batteries. 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.
2, however, the Qi standard electromagnetic induction technology has limitations, such as short transmission distance, affected by the placement position, which is its main problem. Factors that affect battery life Although there are concerns that wireless fast charging will harmBattery life, but in fact wireless fast charge itself will not. Battery life is affected by a variety of factors, such as faulty charging habits (excessive discharge and frequent charging), high temperatures, and non-compliant charging devices.
3, wireless charging bank does not harm the mobile phone battery. Because the working frequency of wireless charging is now below 1M, it will not affect the signal of the mobile phone. On the contrary, wireless chargers not only reduce the use of data cables, but also make charging methods more free and safer.
