Electric cars, plug-in hybrid vehicles, robots and industrial machines will soon no longer have to be supplied with electricity via cables, because the wireless transmission of high outputs is now making real progress.
The signs of a wireless future begin with this technology becoming a larger market.
Everything works towards one goal: The power cables that were needed to charge electric vehicles and in industrial applications inevitably end up in the rubbish bin of history.
They are being replaced by wireless power transmission, according to Techpally – a technology that is making rapid progress, thanks to intensive investments in research and development.
Is there Hope for Wireless power transmission?
Wireless power transmission has already found its way into consumer products and caused a sensation.
This not only applies to smartphones, but for a long time also to electric toothbrushes and similar devices, which offer real advantages over their predecessors, says chaktty.
In the industrial sector, on the other hand, progress has been somewhat hesitant with wireless energy transmission, because the power to be transmitted here is in the kilowatt range, while it is a few watts for the small devices in the consumer market.
According to businesspally magazine, the industry demands better management modules, a consistent, standardized design architecture and more robust materials.
Wireless energy transmission and IoT
The pursuit of wireless transmission of high performance has increased in recent years – parallel to the growth in industrial automation and autonomous systems.
Wireless energy transmission will also play an important role in the Industrial Internet of Things (IoT).
This means there’s going to be rapidly growing inventory of networked machines, computers and sensors that will make everything possible more intelligent and efficient – from healthcare to aircraft to energy generation, Techpally boss affirmed.
Wireless energy transmission will not only make these applications more mobile.
By forgoing plugs and sockets, they can also be completely sealed so that they can work reliably under the most varied of demanding environmental conditions.
Just imagine: industrial robots will be able to move autonomously from one station to another to be where they are needed, and they will recharge when and where it suits best.
The future of wireless power transmission is here
The future belongs to wireless power transmission, emphasizes chaktty, Senior Systems Engineer at Texas Instruments, who works on the elementary components that systems need for wireless power transmission.
When we free autonomous applications in factories, in robotics as well as in aerospace and automotive applications of cables, the most diverse possibilities open up.
Cables snaking across floors and tables have been a common sight since power tools and other industrial electrical appliances first arrived more than a hundred years ago.
However, all sorts of problems arose with these cables as well.
Not only do they hinder the mobility of a device, but they also create weak points in technical devices, no matter how carefully worked out, because water, dirt and air can penetrate into connectors, not to mention the wear and tear on devices due to continuous plugging in and out.
Last but not least, in factories and other areas, cables pose a significant hazard to people and machines having to move around them.
Since the appearance of these first electrical innovations, the idea of wireless power transmission had been a dream, but its realization initially seemed utopian.
The eccentric and brilliant inventor Nikola Tesla came up with the vision of a wireless power supply network that would span the globe and be tapped by machines that need a power supply.
However, his experiments failed. Others made slow advances in the transmission of electricity during the 20th century, but it is only in the last few years that the possibilities of wireless energy transmission have really been realized.
