Wireless charging technology uses non-contact mediums to transmit power over a distance through metal coils and receivers, providing power to devices. The dominant wireless charging standard widely recognized by the industry is the Qi standard established by the Wireless Power Consortium (WPC). It is a short-range, low-power wireless inductive power transfer interconnection standard applicable to mobile devices such as smartphones. It is a convenient wireless charging method for users. With the rapid development in infrastructure, wearable devices, and other fields, wireless charging technology has found applications in these areas. Predictions suggest that the wireless charging market will grow to nearly $15 billion annually by 2024. Wireless charging technology brings significant benefits to users and public infrastructure.

In particular, the global Battery Management System (BMS) market is expected to experience exponential growth in the next five years. Currently, electric vehicles (EVs), hybrid electric vehicles (HEVs), and plug-in hybrid electric vehicles (PHEVs) all require charging, and the trend in the development of these vehicles is expected to drive the growth of the BMS market. To address the growing trend of electric vehicles, we are committed to developing robust and high-performance solutions for the automotive BMS market. This aligns with the emerging trend of harnessing energy storage.

So, how can wireless charging technology be applied to expand this emerging energy storage system? This article will start by explaining the basic principles of wireless power transmission, focusing on the analysis and application of the four ways of wireless charging and their comparative features. Concurrently, it will discuss the gradual shift from flexible wireless charging technology to a new initiative and examples of high-power energy storage.
