Introduction
In this world, we are becoming more and more connected to our devices, and the continued shift toward the adoption of wireless power technology is changing how we interact with our gadgets. If you’ve ever suffered due to cords (not being available, or carried a wrong or damaged port) or waited in vain for an available outlet, you’ll appreciate the magic of wireless power.
This convenience is moving beyond the confines of smartphones into larger applications such as electric vehicles, promising a future when charging is as easy as placing the device on a wireless charger. The blog covers an important point about the evolution of wireless charging, its current applications and its bright future.
The Rise of Qi Charging
Fast forward to the early 2000s when the Institute of Electrical and Electronics Engineers, or IEEE, published standards for wireless charging. The Qi standard from WPC (Wireless Power Consortium), which was out in 2008, became a staple for wireless power applications. Devices such as smartphones, smartwatches, and wireless earbuds could now be wirelessly charged on simple charging pads without needing to plug them. Some brands quickly embraced this technology, causing a shift in the way we think about charging.

Recent Development
Wireless power technology has already gone through a good level of advancement in the last few years:
•Efficiency Improved: The initial wirelessly charged technology solutions were somewhat not as efficient as they are now. Nevertheless, with the utilization of resonant inductive coupling, scientists accelerated the rate at which power is transmitted highly.
• Faster Charging Speed: The implication is that newer systems can charge faster, some almost similar to the traditional wired charging method.
• Creative Designs: From car mounts to bedside tables to embedded fixtures, innovative designs are making it easier to integrate wireless charging into our daily life.
Growing adoption beyond Smartphones:
Wireless Electric Vehicle Charging (WEVC)
As the number of EVs grows, so does their need for efficient charging solutions. Wireless charging pads embedded into garages, driveways or parking spots are a highly exciting solution. Just think of pulling your EV into your driveway or parking space and letting it charge wirelessly (automatically) without fumbling for a charging cable and the right plug! Such an easy form of convenience and accessibility. One also experiences ease of use – one forgets the hassle of pulling out a charging cable; and goes and parks on top of a wireless EV charging spot. One also doesn’t need to worry about the wear and tear related to constantly having to use the plug for everyday charging.

Charging wirelessly on a massive scale can transform public transport and urban infrastructure. A couple of projects are underway testing the ‘continuous’ dynamic wireless charging solution for the EVs, where wireless charging-enabled EVs will be continuously charged while driving on the road which is equipped with wireless charging transmitters.
Restaurants, hotels, stadiums, parking centres, airports, malls and many such destinations are looking to install wireless charging stations allowing customers to drive in and power up their devices without waiting to plug their EVs and sit tied to a wall charging port).
Future of Wireless Power Technology
Gradually but the future is going to be wireless. More and more application sectors are adopting wireless power. In addition to mobile devices (smartphones, smart watches, wireless earphones), wearables, and other consumer devices, we are seeing growing adoption of wireless power across computing devices, home appliances, e-mobility (electric vehicles, e-bikes/e-scooters, micro-mobility), robotic devices, medical/healthcare devices, industrial, retail, IoT, defence, and other devices.
Considering the various form factor and power characteristics and requirements ofeach application devices, the overall wireless power technology market will see adoption of various type of wireless power solutions – low/high/ultra-high frequency solutions, including NFC Wireless Charging, RF-based, infrared-based and other emerging technologies. Market is expected to see a adoption of industry-standard based as well as proprietary-based wireless power-based technologies.
From power perspective, we see solution for less than 1W to more than 200kW wireless power solution. From distant perspective, we have tightly coupled to long distance-based wireless power solutions (less than 1 inch to couple of miles away).
Challenges and Considerations
However with promise comes obstacles. While going forward with its promises, the wireless power technology has several challenges to face:
• Cost: Investment in such systems might be costly at first. However, as the technology continues developing, it should be more cost-effective soon.
• Energy Efficiency: Wireless charging has improved much but is much less energy efficient compared to the wired mode of charging. Energy-based improvement in transfer rates still remains in research.
• Interference: Functions might be affected by interference from other devices, creating difficulties while designing universal wireless power systems.
