The US Federal Communications Commission (FCC) has approved the world's first "long range" wireless charging transmitter with commercial conditions. The product came from WattUp Mid Field, a wireless charging transmitter owned by NASDAQ-listed Energous. Energous' share price rose 257% on two days. WattUp Mid Field wireless charging technology can transmit power within 1 meter, which means that in the future we can put the charger in the cabinet, desk, and then automatically charge within one meter, and can support multiple devices at the same time. Charge over long distances. Engerous's major shareholder, Dialog, is Apple's important supplier of power management chips, and the prospects for future cooperation are expected.
Compared with the "contact wireless charging technology" of Apple's mobile phone, the wireless charging technology within 1 meter has a wider application range. However, there is public opinion that although the wireless charging technology within 1 meter is better than the contact wireless charging technology, there are still limitations in practical applications, and the range is too small for the person using the mobile phone to move largely.
According to another source, the company is also developing long-distance wireless charging technology from China. It has realized a charging distance of 5 meters from the air. If a hidden transmitter is installed at home, consumers will hold the mobile phone. Charging is achieved when you walk around at home.
The comparison shows that the portable communication technology company has a longer charging distance than the US Energous company, and the application prospect is broader. The difference is that China's energy-carrying company uses electromagnetic super-surface materials, mobile tracking, multi-point focusing technology, which is better and safer than Energous.
The company has more than 20 patents in long-distance wireless charging technology, and signed a cooperation agreement with Haier Wireless in early 2017. At the end of the year, it joined the National Household Appliance Technology Standard Innovation Base. The company is currently accelerating the application of long-range wireless charging technology in joint research institutes, including smartphones, tablets, Internet of Things (IoT) devices, small wearable devices, and virtual reality (VR)/amplified reality (AR) devices. Wait.
At present, the technology upgrade of smart phones is in a state of stagnation, and these remote wireless charging technologies may become the next major innovation point of smart phones. The consumer demand of the masses is unstoppable, and the era of long-distance wireless charging is coming.
