Charging e-bike batteries without a cable


Companies wishing to tap into wireless battery charging for e-bikes and other small electrical vehicles can now turn to Würth Elektronik for support.

For many years now, the supplier of electronic and electromechanical components 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 worldwide. 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 Elektronik 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 2,000 and 5,000 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 at Würth Elektronik eiSos. “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.”
