GOOD DESIGN AWARD 2025 CEREMONY

Established in 1957 by the Japan Institute of Design Promotion, the Good Design Award is Japan's only comprehensive design evaluation and promotion system. Its renowned G-mark is globally acknowledged by both consumers and designers as a symbol of "Good Design." The award's evaluation focuses not only on product aesthetics but also on usability, innovation, and positive impacts on society and the environment.

The judging committee praised EP Cube highly, "This product, with its highly modular and user-friendly design, skillfully integrates complex energy storage technology into daily life. It lowers the threshold for households to use clean energy and serves as an outstanding example in promoting energy democratization. The system's compact form factor seamlessly blends into home environments, while its intelligent disaster early warning capabilities provide households with crucial peace of mind."

The core of EP Cube lies in its revolutionary stackable, expandable modular design. Users can customize system capacity according to household energy needs. This "configure on demand" concept completely breaks through the limitations of fixed capacity in traditional energy storage equipment.

Particularly worth mentioning is how EP Cube demonstrates thoughtful humanized design considering the Japanese market's high requirements for space utilization and operational convenience. Its compact design efficiently adapts to limited installation spaces and harmonizes with various home environments. The HMI display allows users to check crucial information like battery level and operational status in real-time, significantly enhancing daily convenience and intuitiveness. Additionally, users can remotely monitor solar power generation, battery storage, and household electricity consumption in real-time through the EP Cube App, set system behaviors, check weather conditions, and prepare energy backups in advance before severe weather arrives. The system can automatically stores emergency power when disaster alerts are issued, ensuring reliable backup during outages.

Beyond excellent hardware and software design, EP Cube makes a solid commitment to users with robust quality. The product comes with a 15-year warranty and guarantees that the battery capacity will remain no less than 60% during the warranty period. This policy, far exceeding industry standards, aims to provide users with peace of mind across cycles, redefining the quality standards for home energy storage products.

It is reported that the award-winning EP Cube will be publicly displayed at the "Good Design Award Winning Works Exhibition" at Tokyo Garden Theater starting November 1st. Visitors worldwide will have the opportunity to experience this home energy storage product that combines exceptional design, user-friendly details, and reliable performance.

"We are truly honored that EP Cube has received recognition from the Good Design Award," said Andy Yin, Founder and CEO of EP Cube. "This proves that our team's relentless efforts in integrating 'Design Thinking' with 'Sustainable Technology' have been acknowledged by international authority. EP Cube is not just a product; it carries our mission to 'make clean energy worldwide.' We will take this opportunity to continue deepening product development and design innovation."
