1, Tesla acquired the German WIFERION, in the modified version of the Model 3 application of wireless charging technology, behind the logic 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.
2, and recently Apple has continuously begun to poach Tesla's vehicle designers, great ambitions to seriously build cars.
3, onlyAt this stage, the power of wireless charging is low, the charging speed is slow, the charging time is long, and it can only be slowly charged, and it can not achieve fast charging, and the energy conversion efficiency is not as high as the plug-in charging efficiency. For example, BMW's wireless charging power is only 3kw, and the wireless charging scheme made by a domestic electric vehicle company can reach a maximum power of 11kw. Such charging power, compared with the current stage of the charging pile power, is still very low.
4. It's true. This way of charging is very fresh and convenient, but there are concerns about radiation. In this regard, Fox Ling Ling intelligent Technology Co., LTD. Chief engineer Mo Guifu solution wireless charging technology radiation is verySmall, far less than the radiation of mobile phones, the installation of the receiver will not affect the normal use of electric bicycles.
Connect the charger to the power supply. Please use the power adapter that comes with you or the power adapter recommended by the manufacturer. Place the charger on a horizontal surface. Place the iPhone on the charger with the display facing up. For best performance, place your phoneThe center of the charger.
Put the mobile phone with wireless charging function on the wireless charging board, the position should be placed, you can charge, note that some wireless charging panel supports different mobile phone models, you should choose wireless charging panel according to your mobile phone model.
There are four basic principles of wireless charging, respectively, electromagnetic induction charging, magnetic resonance charging, radio wave charging, electric field coupling charging, the mainstream standards on the market mainly Qi standard, PMA standard, A4WP standard, iNPOFi technology and Wi-Po technology. Let's take a look at the principle of wireless charging.
Low-power wireless charging often uses electromagnetic induction, such as the Qi method of charging mobile phones, and ZTE's electric vehicle wireless charging uses induction mode. High-power wireless charging usually uses resonance (most electric vehicles are charged this way) to transfer energy from the power supply device (charger) to the electrical device. The device uses the received energy to charge the battery and at the same time provide energy for the battery's own operation.
At present, consumptionThe main wireless charging standards in the field include the Wireless Charging Alliance's Qi, 4AWP and PMA three standards. In terms of market size, Qi is undoubtedly the most popular at present, and the latest standard of Qi can achieve a wireless charging distance of 7 to 45 mm, which is a small breakthrough. A4WP's wireless charging technology, called "Rezence", uses resonant coupling technology, and although it has occasionally appeared at some consumer electronics shows, it has not yet been officially commercialized.
Qi wireless charging, simply put, is a use of electromagnetic induction principle, through the Qi standard for mobile phones, cameras and other small equipment wirelessThe technology of charging. This standard is formulated by the world-renowned organization Wireless Power Alliance (WPC), and has been widely accepted and applied by the industry, including Apple, Samsung, Nokia and other global giants have adopted Qi as the wireless charging standard for their devices.
Wireless fast charging mobile phones are Xiaomi Huawei P40, Mate30, Mate30 pro and so on. Wireless charging technology Because the charger and the electrical device transmit energy by magnetic field, the two are not connected by wires, so the charger and the electrical device can be no conductive contact exposed. The principle of fast charging of mobile phones is to increase the charging voltage
