Belander was invested and established by the former Samsung high-end R & D talents. In 2011, it began to develop and design wireless charging scheme. As the first provider of R & D and application wireless charging scheme in the industry, it is currently developing WPC Qi A4wp and PMA wireless charging schemes have been successfully applied to smart wearable devices, including smart watches, smart bracelets, glasses, backpacks, shoes and other wearable products.
At present, the most widely used wireless charging technology in intelligent wearable products is WPC Qi standard. Qi wireless charging scheme is divided into two parts: transmitting and receiving. The main functions and technical parameters are as follows.
