Tesla acquired the German WIFERION, on a modified version of the Model 3The application of wireless charging technology, the logic behind 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.
First of all, Tesla's wireless charging technology uses the principle of electromagnetic induction. The 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.
Wireless charger refers to the charger that does not need to be connected to the terminal device that needs to be charged without the traditional charging power cord, using the latest wireless charging technology, wireless charging technology obtained 20 patents in 2007, a variety of devices can use a charging base station, Wired charging for cell phones, MP3 players, power tools and other power adapters will no longer exist.
The charging process of Tesla takes about 12 hours, but when using a home charger, the voltage may drop due to the peak load of the transformer, which affects the charging speed. For promotionCompared with the previous wireless charging method, the air separation charging technology no longer relies on the charging base, whether it is a handheld mobile phone or a mobile phone in a pocket, wireless charging can be achieved. In addition, this technology also supports multiple devices charging at the same time, even if there is an object blocking, it will not affect the effect of air charging. The application range of air separation charging technology is also more extensive. In their blog announcement, Xiaomi revealed the breakthrough system, which not only charges multiple devices simultaneously, but also penetrates barriers and, through clever rectifier circuits, converts these millimeter waves into a source of power to charge the phone's battery. Back to fourYears ago, Disney used Tesla's coil circuit as a basis for demonstrating the potential of wireless energy transmission.
Xiaomi wireless charging treasure can support charging for 3 devices at the same time, multi-channel charging is very powerful, of course, it has such a convenient charging characteristics, it will inevitably sacrifice a little thing.
1, from the theory, wireless charging technology is safe and harmless to the human body, and wireless charging uses resonanceThe principle is magnetic resonance, which is transmitted only between coils resonating at the same frequency, and other devices cannot accept the band, in addition, the magnetic field used by wireless charging technology is itself harmless to the human body.
2, the principle is through the use of the magnetic field generated between the coils, generate current, for transmission.
3, mobile phone wireless charging system mainly uses the principle of electromagnetic induction, energy coupling through the coil to achieve energy transfer. When the system works, the input end converts the AC mains into direct current through the full bridge rectifier circuit, or uses the 24V direct current end to supply power to the system directly. Wireless charging technology is a specialPower supply mode, it does not need a power cord, relies on electromagnetic wave propagation, and then converts electromagnetic wave energy into electricity, and finally realizes wireless charging.
4, charging base: ensure that the wireless charger or charging base used is compatible with your Huawei mobile phone, and supports the Qi wireless charging standard. Under normal circumstances, you can find the applicable wireless charging equipment on Huawei's official website or relevant third-party sales channels. Charging efficiency: Although the development of wireless charging technology has a high efficiency, there may still be a certain energy loss compared with wired charging.
5, buy wireless chargingDevice: Choose a wireless charger that matches your phone model and brand. It should be noted that the charger should comply with the Qi standard, which is a widely used wireless charging technology. Plug the wireless charger: Plug the wireless charger into a power outlet, and then plug the charger's power adapter into the charger. Prepare the phone: Find the wireless charger compatible location on the back of the phone.
1, electromagnetic induction charging technology: This wireless charging technology through the electromagnetic induction principle to achieve energy transmission. fillingA certain distance should be maintained between the electric base and the charging device, and the charging device should be placed on the charging base for charging. This technology has high charging efficiency and is suitable for small electronic products such as mobile devices.
2, Bluetooth charging: Bluetooth charging is a relatively new wireless charging technology, through the Bluetooth signal transmission of energy, the charger and the mobile phone wireless connection, and the energy transfer to the mobile phone for charging. Inductive charging: This technology transmits energy through inductive electromagnetic fields, and there needs to be a certain distance between the phone and the charger, and the phone can be wireless only when the charger is placed within a certain rangeCharge up.
3, wireless charging methods include electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, wireless charging of mobile phones mostly uses the principle of electromagnetic induction. Electromagnetic induction wireless charging, when the current of the power supply through the coil (wireless charger's power supply coil) will generate a magnetic field, other unenergized coil (mobile phone side of the electric coil) close to the magnetic field will generate current, charging the mobile phone.
4, there are four basic principles of wireless charging, respectively, electromagnetic induction charging, magnetic resonance charging, radio wave charging, electric field coupling charging, on the marketThe main mainstream standards are Qi standard, PMA standard, A4WP standard, iNPOFi technology and Wi-Po technology. Let's take a look at the principle of wireless charging.
5, radio wave type. This is a more mature technology, similar to the early use of ore radios, mainly composed of microwave transmitters and microwave receivers, can capture the radio wave energy bouncing off the wall, while adjusting with the load while maintaining a stable DC voltage. This method requires only a transmitter mounted on the wall plug, and can be installed in any low-voltage product"Mosquito type receiver.
6, convenient: charging does not need to be connected with a wire, as long as it is placed near the charger. Technically, a charger can power multiple electrical devices, and in the case of multiple electrical devices, it can save multiple chargers, do not occupy multiple power sockets, and there is no trouble of multiple wires winding each other.
OPPO wireless flash charging technologyOPPO is keen to capture the new needs of users for wireless charging methods, especially in the field of wireless flash charging. After years of research and development breakthroughs, OPPO has successfully wireless wired VOOC flash charging technology and launched 30W wireless VOOC flash charging. The core of this technology is real-time communication regulation and VOOC isolated charge pump, which enables constant voltage and constant current direct charge, ensuring efficient and safe power input to the battery.
OPPO recently officially announced that the high-profile Reno4 series will be officially released on June 5, of which the most eye-catching highlight is undoubtedly 65W super flash charging technologyThe lowering of the art. The charging speed of this mobile phone is the fastest in the Reno digital series so far, and with its four core technologies, including dual cell design, dual cell MMT process, and dual BTB interface, it achieves the perfect combination of efficient charging and safe discharge.W Super flash charge is the fastest charging innovation of the Reno digital series so far, it has four core technologies, the first is the dual cell design, in this way, OPPO realizes the dual guarantee of efficient charging and safe discharge.
