Support for wireless e-bike charging development

23 October 2019 Power Electronics / Power Management

Companies wishing to tap the comfort and maintenance-free advantages of wireless battery charging for the market of e-bikes and other small electrical vehicles, have the option of turning to Würth Elektronik for development and component support.

For many years now, the company has been actively participating in many committees for the wireless power sector, and possesses one of the largest portfolios of coils for inductive power transmission. Besides standard solutions – for example according to the Qi standard – Würth Elektronik also offers solutions for many other applications, with a special focus on technology for charging battery packs for electric vehicles.

Würth supports electronics developers in how to implement their individual charging concepts. Besides providing expert know-how in the form of training seminars or on-the-spot development support, the company has also designed many development kits that help manufacturers to bring their products to the market more swiftly.

“When a battery pack is charged by cable, you have to reckon with between 2000 and 5000 plug cycles over the battery’s life cycle. Especially because users generally recharge batteries that are not fully discharged on the go to ensure mobility, in many cases the charging sockets and plugs wear out faster than the actual batteries themselves,” explains Sven Lerche, business development manager: New Mobility.

“Repairing charging sockets or charging devices is rarely an economically viable option, and wireless charging is an extremely attractive alternative. Then you’ve also got a number of other advantages like the high convenience factor, the fully enclosed design, and the insensitivity to environmental factors.”

Würth Elektronik emphasises that three popular misconceptions about wireless power are unfounded – for example, that wireless charging suffers from a low electrical efficiency. When the recommended position of the device is even only roughly adhered to – an aspect that can be enhanced by the mechanical design – then the efficiency is about 95%. What’s more, the fear of getting an electric shock or suffering burns is also unfounded: the industrial standards prescribe an automatic switch-off device that cuts in as soon as a foreign body gets between the charging coil and the receiver coil. The technical effort required for this is minimal.

Lastly, wireless power is not expensive, according to the company: the plug and socket are replaced by wireless power coils and slightly more sophisticated electronics, which ultimately can even result in a cost-neutral solution.
