How to perk up your battery life is one of the most critical concerns for all smartphone users. The phase of wireless charging is almost here, with car makers, airports, and restaurant chains setting up charging stations. You can merely place your phone on the table to renew the battery, instead of having to carry a charger and plug it in.Wireless charging technology is becoming increasingly trendy in devices like phones and tablets.
How Does Wireless Charging Work?
Wireless charging uses an electromagnetic field to transfer energy between two connecting objects, viz. a device and a charger. Wireless chargers produce an irregular magnetic field through the transmitter coil. It produces a sporadic voltage/current using the magnetic field in the gadget.Nearly all wireless chargers work at nearly 40% efficiency, where a decent cable can supply twice that quantity.
The worldwide wireless charging market size is predicted to attain USD 22.25 billion by 2022, according to Grand View Research, Inc. The industry is noticeably driven by the augmented need for hassle-free charging pads. Healthcare and military services sectors have lately witnessed the high adoption of this technology. This will certainly provide new growth avenues for market development during the forecast period (2015-2022).
Asia Pacific dominates the wireless charging market at this time. It held for 35% of the total revenue in 2014. It is the most profitable region for consumer electronics (laptops and smartphones) and most skilled sector for manufacturing hybrid electric vehicles.
Wireless Charging Technologies
Technologies covered in the industry involve:
- Radio Frequency (RF)
Being an extremely mature technology, inductive has expanded drastically and consumed almost 50% revenue shares of the wireless charging market in 2014. Important standards such as PMA (Power Matters Alliance) and WPC (Wireless Power Consortium) use inductive technology.
Resonant and Radio Frequency (RF) are rising at a productive pace in the industry. Resonant technology enables powering the devices across small distances. Also, this technology allows numerous devices to be charged concurrently. RF technology will gain preference by small devices; for instance medical implants and wearables.
Glance at the Future
In the future, wall-sized charging stations can charge numerous devices in multiple rooms with no definite positioning or closeness. New wireless charging standards can be a game-changer in the near future.
