As for the electromagnetic wireless charging scheme, aluminum can also be used to replace copper as raw materials to a certain extent, thereby reducing manufacturing costs.
For pure trams, the most reliable solution now is electromagnetic induction, which is more stable and reliable. Although magnetic resonance can have a higher power distance advantage (a few centimeters to a few meters), it is difficult to control, technical difficulty is high, and it is not easy to use for electric vehicles (this may be the development direction of wireless charging in the future).
It is worth mentioning that the Ministry of Industry and Information Technology recently released "wireless charging.Fast charging cannot be achieved, and the power 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.
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. The current modified Tesla Model 3 can achieve up to 12KW wireless charging powerThe fastest one hour to make up 80 kilometers, full may take about 6 hours.
Is true. This way of charging is very fresh and convenient, but there are concerns about radiation. In this regard, the radiation of wireless charging technology is very small, far lower than the radiation of mobile phones, and the installation of the receiver will not affect the normal use of electric bicycles.
To answer this question, we need to start from the development of wireless charging and its principle. History of the development of wireless charging In the 1830s, Michael Faraday discovered that changes in the surrounding magnetic field will be in the middle of the wireGenerate electricity. In the 1890s, Nikola Tesla, an assistant to Edison's spectral radiation research project, proposed the idea of wireless power transmission.
1, mobile phones that support wireless charging are: millet Samsung S10 series, millet MIX2S, millet MIX2S, Huawei Mate20PRO, iPhoneX, iPhone8 and iPhone8Plus. Wireless charging technology is derived from radio energy transmission technology, which can be divided into small power withoutLine charging and high-power wireless charging two ways.
2, many vivo/iQOO models of mobile phones support wireless charging function, Including iQOO 11 Pro, X90 Pro, X90 Pro, X Fold, iQOO 10 Pro, X80 Pro Snapdragon, X80 Pro Guet, X Fold, X Note, iQOO 9 Pro, X70 Pro, iQOO 8 Pro, etc. It brings convenient charging experience to users.
3, OPPO support wireless chargingElectricity mobile phone, oppoFindXoppoFindX3pro, oppoFindX3neo, oppoFindXopporenoopporeno8pro, oppoFindX5pro, oppoaceoppofindn, oppox2021. The opporeno8 is a smartphone released by OPPO.
4, Apple supports wireless charging models are iPhone8 series, iPhoneX series, iPhone11 series, iPhone12 series, the iPhone13 series and the iPhone 2 and later versions. When Apple supports wireless charging, because the induction coil is added to the back of the phone, it is charged by radio magnetic induction, and the Apple phone supports 15W wireless charging, and the efficiency is close to fast charging.
5, for which mobile phones support wireless charging, the following is a list of wireless charging devices of some mainstream brands: vivo/iQOO: iQOO 11 Pro, X90 Pro, X90 Pro, X Fold, iQOO 10 Pro, X80Pro (Snapdragon and Guet), X Fold, X Note, iQOO 9 Pro, X70 Pro, iQOO 8 Pro.
1, mobile phone wireless charging refers to the charger and the electrical device between the two can charge the phone without wire connection. 2, wireless charging, also known as inductive charging, non-contact inductive charging, from wireless power transmission technology, is the use of near-field induction, that is, inductive coupling, powered byThe device (charger) transmits energy to an electrical device, which uses the received energy to charge the battery and at the same time for its own operation.
3, wireless charging means to provide electrical energy for electronic devices through wireless means. Wireless charging is a modern technology that does not require a traditional physical cable connection to charge electronic devices. The basic principle is to use electromagnetic induction or radio waves to transmit energy. This technology uses a charging dock or charger to wirelessly sense the device to transfer power. The specific principles and technical implementation of wireless charging have many waysStyle.
