Since the birth of smart phones, they are constantly advancing with the times in terms of charging. So far, they have not only realized wireless charging, but also realized fast charging of 100 watt. According to a newly exposed Huawei patent, they will be able to usher in another major change in the near future.
As can be seen from the exposure news, this Huawei patent still belongs to the category of wireless charging, but the medium is changed to laser, so it not only realizes long-distance charging, but also far exceeds the current wireless charging technology. At the same time, Huawei has also considered the safety issue, so it can automatically interrupt the charging when the laser meets the human eye.
Laser charging technology is a technology for long-distance energy transmission by using optical fiber, which was jointly developed by Lockheed Martin and laser power supply company of the United States. The laser charging system developed by it uses optical fiber lighter than copper wire for energy transmission, which can provide uninterrupted and safe energy for UAV. In essence, laser charging actually uses laser beams and batteries to realize long-distance wireless charging by converting light energy into electric energy, which can usually be applied to the battery life of drones and the charging of portable appliances. The laser remote charging system mainly consists of a laser transmitter and a laser receiver.
