Motorola announces dream wireless charging technology (but is it still a long way off?)

Just enter a rechargeable room, and it will be charged automatically! Complete wireless charging is a dream of humankind!

Following Xiaomi and Oppo, Motorola will also showcase its wireless charging technology. It features the ability to charge several devices at once, and the charging range is quite broad.

In May this year, Motorola worked with GuRu, founded by a group of engineers at the California Institute of Technology (CalTech), to develop a wireless power solution called ” Space Charging .”

It was already clear that Motorola was working in this technology area. Still, it was first shown in a live presentation at the parent company Lenovo’s “Tech World” event this week. The exhibition begins with a central charging station with an enterprise router installed, and four smartphones appear. Place each in the holder to indicate that the battery indicator is charging.

This video shows distances from 1 meter to 3 meters to show the ability to charge long distances using space charging. Even at about 1.5 meters from the base station, any device equipped with a compatible chip can be charged.

The device is automatically charged when you enter the base station’s room without physically placing your smartphone in a specific charger. Still, the technology and image of WiFi and mesh networks are similar.

Motorola is a “charging cable is not required, must also do not have to consider the location of power” explanation. Furthermore, this charging base covers a wide range of 100 degrees and can be charged even if obstacles, such as paper and leather. Moreover, the base station is equipped with a “phased array consisting of 1,600 antennas.”

Even more interesting is the built-in “biomonitoring” that identifies when someone enters the room. After recognizing the human body, it is possible to stop or avoid part of the charging beam.

The speed of wireless charging for Motorola this time remains a mystery. Space charging seems to be at most 5W, but this seems to be quite subtle compared to the average fast charging speed of 18W. By the way, Oppo’s wireless charging solution is 7.5W, and Xiaomi is 5W.

Various companies are announcing smartphones equipped with wireless charging technology, and Oppo announced “Wireless Air Charging” in February this year, but the range of support is only 10 cm. Xiaomi’s “Mi Air Charge Technology” allows multiple devices to be charged at the same time but has not yet been commercialized. Ossia has also been certified by the US Federal Communications Commission for its Cota wireless power system, but with a charging range of up to about 1 meter.

And Motorola’s space charging technology and other wireless charging solutions are unlikely to be readily available to the general public. This is partly due to the different regulations in each region and country of the United States. In the case of Ossia, the chargeable range is limited in the United States but not in the EU or the United Kingdom. Gadget makers are working hard every day to bring this technology to market, but there are still many challenges and regulatory hurdles.

Also, I would like you to consider that in the early days, wireless charging technology did not fall into the pitfalls of proprietary technology (technical modification, duplication, etc., are legally or technically restricted to monopolize the technology).

It’s a dream to be charged automatically when you enter the room, but it doesn’t seem practical yet.
