But the advantages of wireless charging are also very obvious. Since there is no need to plug and unplug the charging gun, the convenience of charging is significantly improved, and the risk of electric shock is reduced. More importantly, if dynamic wireless charging mode is deployed, it can greatly reduce the amount of battery power carried by electric vehicles, reduce the cost of the vehicle, and completely solve the user's driving range anxiety.
Low-power wireless charging often uses electromagnetic induction, such as the Qi way of charging mobile phones, but inXing's electric vehicle wireless charging method is inductive. High-power wireless charging High-power wireless charging usually adopts a resonant mode (most electric vehicle charging in this way) by the power supply device (charger) to transmit energy to the electric device, the device uses the received energy to charge the battery, and at the same time for its own operation.
Secondly, wireless charging technology wants to be truly popular, and it also has high requirements for the precise positioning and intelligence of vehicles. 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 precisionIn the case of positioning, the footprint is the same, and the number of electric vehicles using wireless charging will be greatly increased compared with the traditional charging pile, which greatly improves the space utilization and charging efficiency.
Wireless charging of electric vehicles is very strange to consumers, it is like we look at the concept car is a future scene. However, if it can be achieved, it can greatly alleviate the impact of inconvenient charging.
Electric vehicle wireless charging technology is delivered at high frequency through a power supply guide rail buried under the groundIn the form of variable magnetic field, the 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 Car wireless charging upgrade , and then power the vehicle energy storage equipment. When charging begins the power transmitter PTx generates an alternating current through its coils, thus generating an alternating magnetic field according to Faraday's Law.
The breakthrough of the technology is to find a way to "catch" electromagnetic waves, that is, to use the "resonance" principle of physics - two objects with the same vibration frequencyIt can transfer energy efficiently. The system consists of the main circuit located outside the car and the secondary circuit, rectifier and drive system located inside the car.
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.
is achieved by using the principle of electromagnetic induction. The principle of in-car wireless charging technology is through the use of electromagnetismTo achieve the principle of induction. Specifically, the wireless charger has a coil inside, and when this coil is connected to the power supply, it generates a magnetic field. The mobile phone or device placed above the wireless charger also has a coil inside, when the coil is close to the wireless charger coil, it will sense the magnetic field, thus generating a current to achieve 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. High-power wireless charging usually adopts a resonant mode (most electric vehicles are charged in this way) by the power supply device (charger) to transmit energy to the device that uses electricity.
How to wireless charging the car wireless charging How to use the car wireless charging method is: the car wireless charging is fixed in the appropriate position in the cab; 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.
First fix the wireless charging device on the car in a suitableThen plug the wireless charger's data wire into the interface of the cigarette lighter, and after the other end of the interface is connected to the wireless charger, check again whether the placement position is suitable to ensure that it will not slip off during driving, you can use wireless charging normally.
On the right side of the wireless charging panel is the switch, press this switch to power the panel, and put the phone on it. Many cars will be equipped with wireless charging function, and many mobile phones support wireless charging function, which is not a rare function. Trumpchi is a self-owned brand, which has a lot of cars and SUVs. Trumpchi
