Application environment Harsh wireless charging transmitter is generally arranged on the ground of the parking space, if the parking space is outdoor, you need to ensure that even in lightning, rain and snow, high temperature exposure, low temperature freezing and other harsh environment can still work effectively. Even indoors, you need to consider the possibility of being run over by wheels or trampled by pedestrians.
Wireless charging mobile phone popularity limited factors Wireless charging mobile phone Why rare? On the one hand, the inconvenience of its use form is an important factor. The early Nokia Lumia 920 is insideIt has not been widely popularized, and to use WiFi wireless charging, the premise is that the mobile phone must be supported, and the WiFi must also be upgraded.
Wireless charging has another advantage is to save power, wireless charging device performance reception of about 70%, and wired charging device is equal, but it has a full automatic shutdown function, to avoid unnecessary energy consumption. Moreover, this performance reception rate is constantly improving, and will soon reach 98%.
In general, wireless charging can not be as far away as WiFi, only close to the charging surface because of magnetic resonance. thisThe use of this method is actually relatively reliable, and it is also relatively simple when on the mobile phone. Only close to the mobile phone can really be full of mobile phone power, wireless charging technology has been constantly developing. It will certainly deal with all the power equipment and will not let it be troubled.
Environmental interference: If there is other wireless signal interference around your wireless charger, such as WIFI, Bluetooth, etc., these may cause wireless charging instability. Mobile phone protective case problem: If your mobile phone uses a heavy protective case, this may affect the stability of wireless charging, it is recommended to use thin and lightThe protective case or directly bare the phone for wireless charging. To solve the above problems, you can try the following measures: Wireless charging.
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.
Compare to passUnified charging method, wireless charging system can indeed greatly improve the convenience of charging, to stop and charge, and wireless charging equipment for lower space requirements. In addition, relying on magnetic resonance wireless charging, it can theoretically be charged while walking, and even is expected to solve the range anxiety of pure electric vehicles.
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 and technical difficulty, and it is not easy to use for electric vehicles.This may be the future direction of wireless charging).
As soon as the driver moves the car over the wireless charger, the system will automatically charge the car. A domestic electric vehicle company is also studying wireless charging technology, which has entered the experimental stage and may be mass-produced in the near future. In fact, wireless charging technology is not a tall technology, it is the use of electromagnetic induction principle or magnetic field resonance principle, to achieve the wireless transmission of electric energy.
