1, how the car wireless charging vehicle wireless charging How to use the car wireless charging method is: the car wireless charging fixed in the drivingA suitable position for the steering chamber; Connect one end of the USB data cable of the wireless charger to the car cigarette port and the other end to the wireless charger; After fixing the position of the wireless charger, make sure that it is stable and will not slide, put the phone on and charge it.
2, first of all, the car wireless charger fixed to the appropriate position in the cab, the wireless charger data cable connector connected to the car's cigarette lighter interface, the other end is connected to the wireless charger, fixed after the wireless charger, ensure that the wireless charger will not slip, the wireless charger can be used normally.
3, in the use of wireless charger, firstMake sure to select a device that is compatible with the vehicle and secure it in a location within the vehicle that is easily accessible, such as a storage compartment in front of the passenger. One end of the USB cable is connected to the wireless charger, and the other end is connected to the car's cigarette lighter interface. Finally, just place the phone on the charging pad and enjoy the convenience of wireless charging immediately.
2, secondly, wireless charging technology wants to be really popular, for the carThe precise positioning and intelligence of the vehicle also have higher requirements. Only when the vehicle is precisely parked in the charging space can the ground system establish a channel with the vehicle's on-board system and achieve charging. In the case of precise positioning, the same footprint, the number of electric vehicles using wireless charging compared with the traditional charging pile charging will be greatly increased, greatly improving the space utilization and charging efficiency.
3, 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. High-power wireless charging High-power wireless charging is often usedWill get some relief.
2, electromagnetic induction - the primary coil of a certain frequency of alternating current, through electromagnetic induction in the secondary coil clock to produce a certain current, so as to transfer energy from the transmission end to the receiving end.
3, as long as the driver drives the car over the wireless charger, the system will automatically charge the car. A domestic electric vehicle company is also studying wireless charging technology, which has entered the experimental stage and may be mass-produced in the near future. In fact, wireless charging technology is not a tall technology, it is the use of electromagnetic induction principle or magnetic field resonance principle, to achieve no electricityLine transfer.
4, clearly raise the charging power limit of mobile phones and other mobile devices to 80W, and stipulate that the management provisions also apply to the wireless charging of electric vehicles. This has undoubtedly injected new impetus into the development of wireless charging technology for electric vehicles. In short, electric vehicle wireless charging technology still faces many challenges, but its development prospects are broad. With the continuous breakthrough of technology and the gradual expansion of the market, we believe that we will usher in a more convenient and efficient era of electric vehicle charging in the future.
5, electric vehicle wireless charging technology has become a hot electric vehicle to become the mainstream, about the problem of battery lifeIt has not stopped, in order to solve the problem of battery life, the 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 on the road while rushing.
6, at present, SAIC Roewe, Beiqi new energy, BYD and other mainstream car companies are also conducting research and development tests on electric vehicle wireless charging. Although there is no production model that supports wireless charging in China, I think it should be coming soon.
1. The electric vehicle wireless charging technology transmits electric energy in the form of high-frequency alternating magnetic field through the power supply guide rail buried under the ground to the electric energy picking mechanism running in a certain range of the vehicle receiving end, and then supplies power to the vehicle energy storage equipment. 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.
2, nuclear magnetic resonance technology (magnetic resonance technology) is behind the wireless charging of electric vehiclesThe power of technological innovation, which cleverly uses magnetic field changes to achieve wireless transmission of energy. In the wireless charging system, one coil is installed as a base component and the other is cleverly integrated into the vehicle structure.
3, 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 simply means that it is used by electromagnetic fields or electromagnetic waves without being connected by a physical wireElectrical equipment is charged.
4, electric vehicle charging methods are mainly divided into two kinds. One is the principle of electromagnetic induction, yes, that is, the electromagnetic induction of junior high school physics, the principle is very simple, but rely on this principle for wireless charging, to achieve it is a matter of recent years, mobile phones such as lumia 920 in 2012 to formally introduce this technology to the mobile phone industry.
5, the wireless charging principle of the car is to convert electrical energy into electromagnetic waves, and then sent to the receiver, and then convert electromagnetic waves into electrical energy. Charging technology is not complicated, mainly using electromagnetic induction and magnetic resonance,However, the biggest difficulty of wireless charging is the lack of a unified standard, the charging time is too long, the efficiency is too low, and the cost is high.
