Powercast is set to disrupt the Japanese market through a strategic partnership with B&Plus, bringing its advanced RF wireless power solutions to one of the most competitive and technologically sophisticated markets worldwide. By eliminating battery dependency, this collaboration helps businesses reduce costs, minimize waste, and align with the country’s long-term sustainability goals.
(Pittsburgh, Pennsylvania) February 18, 2025 — As Japan accelerates its commitment to net-zero emissions by 2050, the world’s fifth-largest energy consumer faces mounting pressure to optimize efficiency and reduce reliance on traditional power sources, driving an unprecedented demand for innovative energy solutions. (1-2) Powercast and B&Plus are addressing this challenge with a strategic partnership, bringing their cutting-edge solutions to one of the most advanced and competitive markets. “Powercast has already demonstrated the impact of RF wireless power through global deployments, including North America, other countries in Asia and more. Our partnership with B&Plus marks the next step in expanding adoption in Japan, bringing our technology to even more industries seeking sustainable, battery-free solutions,” states Charles Greene, COO & CTO of Powercast Corporation.
Powercast is entering a high-stakes environment with the ambition of amplifying its role as a global player. By integrating its RF wireless power into B&Plus’s product designs, the collaboration offers a battery-free alternative that enhances efficiency and reduces reliance on traditional batteries—reshaping industrial and IoT applications with a more sustainable approach to energy consumption.
Redefining Smart Buildings with Wireless, Battery-Free Power Solutions
In a densely populated megacity like Tokyo, sustainability isn't just a goal—it’s a necessity. With over 37 million people living and working in a space where every square meter matters, efficient energy use is critical. (3)
Traditional batteries, often discarded after a short lifespan, contribute to electronic waste and require costly maintenance. The global lithium-ion battery industry is projected to generate up to 1.0 gigaton of CO₂ emissions annually within the next decade, highlighting the urgent need for smarter, more sustainable power solutions. (4)
By eliminating the need for disposable batteries, Powercast’s wireless power solutions offer a smarter, greener approach to energy consumption. Buildings across Tokyo can benefit from battery-free, wirelessly powered sensors that optimize energy use in real-time. "If nobody’s in a room, you can automatically turn the lights off, adjust the HVAC, and save kilowatts of energy—all with small, battery-free sensors,” points out Greene. “The problem has never been the sensors; it’s been the hassle of running around changing batteries. Wireless power solves that."
As Japan advances toward its net-zero target, cutting-edge technologies like RF wireless power will play a pivotal role in shaping a more sustainable future.
Wireless Power Applications: Transforming IoT and Consumer Electronics
From Japan’s advanced industrial IoT ecosystems to its globally renowned consumer electronics sector, wireless power is reshaping energy distribution and consumption—aligning with the nation's push for efficiency, sustainability, and technological leadership.
- IoT: Wireless Power Transfer (WPT) is revolutionizing industrial automation by enabling seamless energy delivery to sensors and IoT devices in hard-to-reach locations. Unlike traditional wired or battery-powered solutions, it reduces maintenance costs, enhances system reliability, and improves operational efficiency. Additionally, WPT offers a more scalable and environmentally friendly alternative, minimizing electronic waste and supporting the next generation of smart, energy-efficient industrial systems. (5)
- Consumer Electronics: From smart home sensors to fitness trackers, WPT is eliminating the need for constant charging or disposable batteries, enabling battery-free devices and wearables.
One of Powercast’s most notable integrations is in Samsung’s globally distributed TV remote controls, showcasing its ability to power mass-market consumer electronics with reliability and efficiency. Beyond remotes, Powercast’s technology powers keyboards, mice, smart home sensors, and even illuminated packaging—providing a sustainable alternative to traditional battery-powered devices. These capabilities open doors for further innovation, allowing manufacturers to reduce waste, lower costs, and extend product lifespans.
“Achieving net-zero emissions requires more than renewables—it demands smarter energy use. With B&Plus’s market expertise and Powercast’s wireless power technology, we’re eliminating unnecessary waste at the source and driving real change in industrial efficiency,” explains Greene.
Powering the Future: How Powercast and B&Plus Are Redefining Energy Efficiency
Powercast has cemented its position as a leader in wireless power solutions, driving innovation in sustainability, efficiency, and design across multiple industries. With 300+ patents and 25 million chips shipped, the company is among the few dedicated to RF wireless power, delivering solutions for a diverse range of applications—from industrial sensors and automotive systems to wearables and consumer electronics.
“With Japan’s strong commitment to sustainability and energy efficiency, our partnership with B&Plus comes at the perfect time. We’re here to help businesses embrace wireless power and move toward a smarter, battery-free future,” highlights Greene.
While Powercast provides engineering and product development expertise, B&Plus leverages its deep market knowledge to drive adoption. To showcase the impact of wireless power firsthand, Powercast solutions are now available for demonstration at B&Plus’s showroom in Saitama, Japan (3-1-2 4F, Omiya-ku Miya-cho, Saitamashi,Saitama-ken, Japan 330-0802), where businesses can experience how this technology can transform their operations.
“We have historically developed products using short-range wireless power but have not had long-range RF wireless power until now thanks to our partnership with Powercast,” mentions Atsushi Kameda, CEO of B&Plus. “We chose Powercast’s RF technology because of their 20+ year track record, their RF transmitters and receivers are easy to integrate into systems, and their engineering and manufacturing expertise will help us solve wireless challenges for customers in Japan.”
