Today to share with you wireless charging what way good knowledge, which will also explain the advantages of wireless charging, if you happen to solve the problem you are now facing, don't forget to pay attention to the site, now start!
< ul>1, static wireless charging Static wireless charging technology is to charge the car when the electric vehicle stops, according to its characteristics, usually suitable for shopping malls/residential parking lots and other occasions.Radiation-type radio energy transmission technology transmits energy through the far field, mainly including radio wave and laser mode, which is suitable for long-distance wireless transmission, due to its low efficiency/low power characteristics, are not mature.
2, wireless charging can be divided into low-power wireless charging and high-power wireless charging two ways, low-power wireless charging often uses electromagnetic induction, such as mobile phone charging. High-power wireless charging often uses magnetic resonance, and the power supply device (charger) transmits energy to the power device, which uses the received energy to charge the battery and at the same time for its own operation.
3, the current wireless charging mode mainly includes three types: electromagnetic induction, magnetic field resonance, radio wave.
4, electric vehicle wireless charging technology mainly uses the 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 relies on the energy transmission between electricity and electricity, converts electricity into magnetism, and then induces electricity. Wireless charging is simply to charge electrical equipment through electromagnetic fields or electromagnetic waves without being connected by physical wires.
5, wireless charging technologyDerived from radio energy transmission technology, it can be divided into two ways of low-power wireless charging and high-power wireless charging. Low-power wireless charging often uses electromagnetic induction, such as the Qi method of charging mobile phones, but ZTE's electric vehicle wireless charging method uses induction.
6, there are five new energy pure electric charging methods, one is constant voltage constant current charging, the second is fast charging, the third is wireless charging, the fourth is to replace the charging technology, the fifth is mobile charging. Pure electric vehicle charging mode Constant voltage constant current charging mode Constant voltage constant current charging mode is very limited, only about 15 A.
If you use vivo mobile phone, you can refer to the following information: wireless charging, also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, you do not need to transfer electricity to the device like the traditional wired charger, but the device that needs to be charged can be charged by contacting the wireless charging base.
Wireless charging, also known as inductive charging, non-contact inductive charging, from wireless power transmission technology, is the use of near-field induction, that is, inductive coupling, by the power supply equipmentThe transfer of energy to an electrical device, which uses the received energy to charge the battery and at the same time for its own operation.
Wireless charging, also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, it is not necessary to transmit electricity to the device like the traditional wired charger, but the device that needs to be charged can be charged by contacting the wireless charging base.
Wireless charging refers to the charger on the terminal device that needs to be charged without the traditional charging power cord, using the latest wireless charging technology, by using the magnetic field generated between the coilsMagical transmission of electrical energy, inductive coupling technology will become a bridge connecting charging base stations and equipment. How to use: Connect the USB cable and plug it into the socket.
Wireless reverse charging refers to: the mobile phone as a wireless charging base, to support wireless charging devices (such as: watches, bracelets, mobile phones, etc.) to charge. Wireless reverse charging technology, derived from radio energy transmission technology, can be divided into low-power wireless charging and high-power wireless charging two ways. Low-power wireless charging often uses electromagnetic induction, such as the Qi method of charging mobile phones, but ZTE's electric vehicle wireless charging method is adoptedUse induction.
Wireless charging, also known as inductive charging, non-contact inductive charging, is the use of near-field induction, that is, inductive coupling, by the power supply device (charger) to transmit energy to the power device, the device uses the received energy to charge the battery, and at the same time for its own operation.
Electric vehicle wireless charging technology has become a hot electric vehicle to become the mainstream, the problem of battery life has not stopped, in solving the battery life problemOn the other hand, various car companies are also trying their best to find a way to solve this problem, in addition to changing electricity and fast charging, in fact, there is a different way, that is, road charging, so that the car runs while rushing on the road.
The logic behind the wireless charging technology applied by Germany's WIFERION, which Tesla acquired, 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.
Wireless charging process will definitely be hot. 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 the Qi method of charging mobile phones, but ZTE's electric vehicle wireless charging method uses induction.
It is reported that at present, mainstream car companies at home and abroad have laid out automobile wireless charging technology, and the state has also promulgated four national standards such as "Electric vehicle wireless charging system Part 1: General Requirements"; New energy Automobile Industry Development Plan(2021-2035) also pointed out that it is necessary to strengthen the research and development of new charging technologies such as intelligent and orderly charging, high-power charging, and wireless charging.
For electric vehicles, wireless charging is mostly through the power supply coil arranged on the ground and the electric coil at the bottom of the vehicle, and the magnetic resonance generated between the coils replaces the traditional power lines for charging the vehicle. This charging method requires higher spacing between the supply and receiving coils. The huge demand for wireless charging technology for electric vehicles makes the research and development of related technologies quite active.
Wireless charging technology for electric vehicles, that is, through electromagnetic sensing
