B&PLUS Enters New Domain of Wireless Power Transfer, Fully Launches Microwave Power Transfer Business

B&PLUS Inc. (Head Office: Hiki-gun, Saitama; President: Atsushi Kameda), a specialized manufacturer of wireless power transfer solutions, is accelerating the development of wireless power transfer products for various fields and applications, leveraging its expertise in lean startup development to establish the wireless power transfer market.

Wireless power transfer encompasses three major technological domains: electromagnetic induction and electric field coupling methods suitable for short distances, and the microwave method capable of long-distance power transfer.

B&PLUS is advancing technological development in each of these areas and launched its wireless power transfer business utilizing microwaves last month. As a technology capable of achieving transmission distances more than 10 times greater than conventional methods, the company plans to sequentially release experimental units for the 920MHz and 5.7GHz bands for developers within 2026.

■ Background for Business Launch

Due to the recent labor shortage in Japan's manufacturing sector, there is an increasing demand for automation of manufacturing processes. Previously, B&PLUS released electromagnetic induction products for AGVs and AMRs that handle manufacturing process automation (Related Article). Furthermore, as an initiative to enhance productivity in manufacturing sites, predictive maintenance, which reduces production line downtime, is gaining attention. In particular, there is a growing need for wireless sensors that eliminate the need for wiring as a means of predictive maintenance for rotating or moving parts in manufacturing equipment. To meet these user needs, B&PLUS has launched a business for microwave wireless power transfer, which can achieve transmission distances more than 10 times greater than conventional methods.

■ Features of B&PLUS's Microwave Power Transfer

One of the challenges in microwave power transfer is improving the efficiency of the transmission antenna and increasing the output of the receiving antenna. However, B&PLUS aims for a more high-output power transfer system overall through high-efficiency antenna design and high-power circuit design suitable for microwave power transfer. Furthermore, we will achieve high cost-performance to enable developers of predictive maintenance systems to use it easily for experiments.

■ Future Plans

We plan to sequentially release wireless power transfer units for the 920MHz and 5.7GHz bands, which can be used in test environments such as anechoic chambers, within the year. Concurrently, for users considering the introduction of these units, we will establish a demo environment for these power transfer units at our wireless power transfer showroom in Omiya City, Saitama Prefecture, and conduct demonstrations and business negotiations.
