1, 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 battery power carried by electric vehicles, reduce the cost of the vehicle, and completely solve the problemUsers' range anxiety.
2, secondly, wireless charging technology wants to be truly popular, and it also has high requirements for accurate 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 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, compared with the traditional wired charging method, wireless charging with no charger connection, voltage stabilityFixed, anti-surge and other advantages have become an important development direction of electric vehicle charging. In addition to the advantages of convenience, safety, reliability and small footprint, it also has the following six advantages: Wireless charging of electric vehicles can improve information and intelligence and reduce labor costs.
4, 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 usually adopts a resonant mode (most electric vehicle charging uses this mode) by the power supply device (charger) to transmit energy to the useAn electrical device that uses the received energy to charge a battery and at the same time for its own operation.
5. The race to build a universal wireless charging technology is in full swing. New and exciting advances in wireless charging technology and products continue to emerge - some companies are focused on one technology, while others support multiple technologies. But the lack of interoperability between the various technologies is still a big problem, because there is no unified wireless charging standard. The idea of wireless power transmission has been around for years.
6, it can be predicted that the future of wireless charging technology will becomeElectric time. Secondly, the wireless charging technology of Tesla cars also has the characteristics of intelligence.
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.
At present, two wireless charging methods of electromagnetic induction and magnetic resonance are used more frequently in the field of electric vehicles. The formerIt is necessary to install the power supply coil in the chassis and the ground respectively, and charge the vehicle through the principle of electromagnetic induction. The latter also requires a transmitter panel and an on-board receiving panel to charge the battery of the electric vehicle through a resonance effect. From the point of view of charging methods, it is mainly divided into static and dynamic wireless charging methods.
[Pacific Auto Network] Tesla model3 has wireless charging. Wireless charging transmits power wirelessly through a process called magnetic induction that occurs between the transmitter coil (charging base) and the receiver coil (mobile phone). This magnetic field generated by the transmitter coil is generated in the receiver coilInductive voltage, used to charge cell phone batteries.
Wireless charging technology is crucial to improving the convenience of electric vehicles, and Tesla chose Plulless's device to improve the user's driving experience. The owner only needs to park the vehicle in the designated position, without manually connecting the charging line, and the device automatically charges, which saves time and is efficient. Tesla's decision demonstrates their emphasis on and investment in wireless charging technology.
Wireless charging technology mainly through electromagnetic induction, magnetic resonance and other ways to achieve non-contact power transmission. For electric vehicles, electromagnetic induction is currently usedResponse and magnetic resonance type two wireless charging methods. Electromagnetic induction wireless charging is suitable for fixed parking Spaces and charging when the vehicle is parked, while magnetic resonance can achieve mobile charging, but it requires large-scale upgrading of road facilities and has a high cost.
W. The Tesla wireless charging board comes standard with a 65-watt USB-C power adapter with 30 coils that can charge three devices that support the Qi protocol, with a single power of up to 15W. Tesla is an American electric vehicle and energy company that manufactures and sells electric vehicles, solar panels, and energy storage equipment.
You can first check whether to start the power, if not charged, you can contact the 4S shop for inspection and maintenance. Tesla (TSLA) is an American electric vehicle and energy companyTesla, which has a market capitalization of $2.1 billion, makes and sells electric cars, solar panels and energy storage equipment.
