Breakthrough in Wireless Charging Market: Researchers Develop an Approach that could Make Wireless Charging Easier and More practical
Posted On April 16, 2022
The fundamentals of wireless power transfer have long been in place. However, current solutions cannot help charge devices anywhere within the world. Moreover, if a single huge transmitter is used to cover a vast region, it causes undesirable electromagnetic exposure. Thus, making it impossible to manage the power flow to specific devices. The solution is that the receiving devices must be in a known place, and the transmitter and receiver must be precisely aligned if multiple small transmitters are employed. This means the system must either use permanent charging stations or include position sensors, communication protocols, and processing to track each device's location.
A novel study might have managed to address these issues. The team developed a power transfer method that works regardless of the transmitter and receiver's position and orientation. The basic concept is where transmission is organized in a grid, and the current flow in opposing directions in surrounding transmitters—for instance, a clockwise loop in one transmitter and counter-clockwise loops in its neighbors. The approach could help advance the Wireless Charging Market as it would make wireless charging more cost-effective and accessible.
A novel power transfer method allows users to charge electronics without the use of wires or connectors. Phones and laptops, kitchen appliances, and warehouse robots can all receive power from the charging area. The power transfer continues even while the device is in motion. This may lead to the technology one day being used to fuel electric vehicles while drivers are on the road.
A receiver captures the magnetic flux between positive and negative transmitters atop the grid of transmitters. This provides an electric current to charge the device. This results in a grid of 'positive' and 'negative' transmitting coils connected by a magnetic flux.
The best thing about the method is that it's both sophisticated and straightforward. No high-end processor is needed or a lot of computations to make the transmitters intelligent.
The system is essentially an electromagnetic system. The approach helps it figure out how to electromagnetically detect the receiver's presence and position.
Although the technology is essentially ready for real-world use, commercial packaging and certification are still required. Meanwhile, the team will continue to improve and refine this technique. According to researchers, there are pilot programs on electrifying highways all over the world. In the future, researchers would work towards increasing the system's power level from 1 kW to around 20 kW. This would facilitate the technology to be utilized to charge electric automobiles. Electric vehicles are a fantastic example of this technology in action.
