If you can transmit power over a longer distance advantages of wireless car charging , and can transmit more power advantages of wireless car charging , here is another medium range wireless charging technology wireless car chargingAdvantages The electromagnetic resonance technology that can transmit energy over a longer distance. Its advantage is that the transmission distance is much greater than the electromagnetic induction, can carry out more than 10cm electromagnetic induction energy transmission, even in the larger distance of the transmission distance, the transmission power can still reach several kilowatts.
Electric vehicle wireless charging technology mainly uses the advantages of wireless car charging mutual inductance in the law of electromagnetic induction. It is also similar to a transformer, which inputs from the primary coil and then generates an induced current on the secondary coil. It mainly depends on the energy transfer between electricity and electricityTransfer, convert electricity into magnetism, and then induce electricity. Wireless charging is simply to charge electrical equipment through electromagnetic fields or electromagnetic waves without being connected by physical wires.
Not only Japan, there are many countries are researching wireless charging roads, at the end of last year, the world's fourth largest automobile manufacturer Stellantis announced on the official website that their innovative dynamic induction charging technology has proved successful after years of research and months of testing. The road for the wireless charging test of cars "Aren"a del Futuro" is officially opened. So now wireless charging technology is also a very hot ranks.
For pure trams, the most reliable solution now is electromagnetic induction, which is more stable and reliable. Although magnetic resonance can have a higher power distance advantage (a few centimeters to a few meters), it is difficult to control, technical difficulty is high, and it is not easy to use for electric vehicles (this may be the development direction of wireless charging in the future).
The electric vehicle wireless charging technology is in the form of a high-frequency alternating magnetic field through a power supply guide rail buried under the groundThe electric energy is transmitted to the electric energy picking mechanism at the receiving end of the vehicle running in a certain range from the ground up, and then the vehicle energy storage equipment is supplied. When charging begins, the power transmitter PTx generates an alternating current through its coils, which creates an alternating magnetic field according to Faraday's Law.
The wireless charging principle of the car is by converting electrical energy into electromagnetic waves, which are then sent to the receiver, and then the electromagnetic waves are converted into electrical energy. Charging technology is not complex, mainly the use of electromagnetic induction and magnetic resonance, but the biggest difficulty of wireless charging is that the lack of a unified standard, charging time is too long, efficiency is too low, high cost.

It also has a metal shell. 6, the configuration of the maximum 20W wireless charging power is still unchanged, the electric clamp arm is canceled, but the material is upgraded to zinc alloy, compared with the electric clamp arm can be said to be less scientific and technological sense, but reduce the operation time waiting for the electric clamp arm, just like the automatic and manual transmission models, notIt must be who is better and who is worse, just different preferences.
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 takeAbout six hours.
For example, Tesla models turn on FSD to automatically replenish 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 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. thisThe 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 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 earsAirplane. According to Tesla's official website, the charging pad has been opened for pre-sale and will begin shipping in February 2023.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 advantage of automobile wireless charging technology is that there is no exposed connector for wireless charging of electric vehicles, which can adapt to a variety of harsh environments and weather, and avoid safety hazards such as leakage and electricity running. 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.
Advantages: convenient. Just put the phone in the designated position of the car, you can wireless charging, no need to use a data cable to connect the phone and the car, it is very easy to useIt's convenient. 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.
Advantages and disadvantages of wired charging and wireless charging The advantages 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, and the charging efficiency is also low,At the same time, the device needs to be placed on the charging base, which is not flexible enough.
Wireless charging good. In wireless charging, the charger and the charged device do not need direct contact, easy to use, strong environmental adaptability, avoiding the physical interface, so there will be no interface wear, sparks, leakage and other problems, in addition, wireless charging can also achieve high voltage, high current, high power charging. The cable is charged. Wireless charging also requires a wired charger, but also more wireless charging board.
Wireless charging is better.The convenience of wireless charging Wireless charging provides users with great convenience. For example, some public places, such as cafes, restaurants and airports, offer wireless charging services where users simply place their phones on the charging mat without carrying additional charging cables. In addition, wireless charging technology is also being applied to furniture and cars, allowing users to charge at any time at home and in the car.
Cable charging is good. In the case of the same charging time, the power of the commonly used wired battery charger is 93% after charging, and the power of the wireless charger is 88% after charging. Obviously, wireless chargers still exist in terms of charging efficiencyThere is still room for further improvement in technology.
Today we will talk about the advantages and disadvantages of wireless charging treasure and wired charging treasure, as well as their applicable scenarios. Advantages and disadvantages of wireless charging treasure: Advantages: Easy to operate: wireless charging treasure is really very convenient, because it through the electromagnetic induction wireless technology, you only need to put the device that supports wireless charging on it, it can automatically charge you, eliminating the tedious plug-in steps.
Wired faster, although wireless charging is a very practical function, but only some users, wired charging faster, wireless chargingThe electricity is more flexible, gets rid of the bondage of the wire, picks up and puts down freely, and can charge quickly without alignment. Both sides have their advantages and disadvantages and can make up for each other.
Apple mobile phone general we are better with direct charging, its charging effect is also a direct point, wireless charging is now a relatively novel way, but I still accept wired charging is better. I always feel that the money will charge the efficiency of the battery will be higher.
