From Installation to Deployment: Yamato Mobility & Mfg. and Gigawatts Begin Joint Development of Portable Level 2 EV Chargers

Yamato Mobility & Mfg. Co., Ltd. (Headquarters: Kawagoe City, Saitama Prefecture, CEO: Akitoshi Suzuki, hereinafter "Yamato Mobility"), which develops, manufactures, and sells resin products and logistics equipment, and operates a mobility business, and Gigawatts Inc. (Headquarters: Chuo-ku, Tokyo, Representative Director: Tomoki Shibata, hereinafter "Gigawatts"), which handles everything from the design and manufacturing to sales and after-sales service of EV chargers, are pleased to announce the commencement of joint development and demonstration testing of a portable Level 2 EV charger.

■ Background of the Portable EV Charger: Eliminating the Hassle of Moving Vehicles to Maximize On-site Efficiency

Traditional fixed Level 2 chargers require extensive installation work, such as foundation work and anchor fixing to the ground. Furthermore, vehicles needed to be moved to a specific space for charging. Especially in sites with limited space and operating on a minute-by-minute basis, this "vehicle exchange work" was a major factor in reducing operational efficiency. The product jointly developed by the two companies can be introduced without extensive installation work if a 200V outlet is available (*). Instead of moving the vehicle, the charger moves to the vehicle. This reversed concept enables efficient energy replenishment without interrupting the current workflow. (*If a 200V power source is not available, simple electrical work is required separately.)

■ Fusion of Yamato Mobility's "On-site Knowledge" and Gigawatts' "Development Technology"

This project is a practical value creation project that highly integrates Yamato Mobility's "on-site capabilities," which are deeply familiar with on-site challenges, and Gigawatts' "vertically integrated technology."

【Yamato Mobility: Synergy of 3 Business Units Shaping On-site Knowledge】

Logistics Business Unit: 【Pursuit of Overwhelming Maneuverability】 Achieved "smooth entry into narrow spaces" that was difficult with fixed or conventional portable chargers, through cart technology developed from a professional perspective. Its agile operability, manageable with one hand, enables efficient operation in limited spaces.

Resin Business Unit: 【Lightweight, Highly Durable, High-Quality Casing】 Developed a dedicated casing that protects the precision charging board using proprietary resin molding technology. Compared to metal, it is lightweight, resistant to impact and rust, providing a robust exterior that supports continuous operation in harsh outdoor environments.

Mobility Business Unit: 【Verification of Business Viability and Practicality】 Promotes commercialization based on on-site knowledge gained from the front lines of actual vehicle operations. Refines it into a practical solution from the perspective of "how to operate to best assist the site."

【Gigawatts: "Compact Circuit Board" and Integrated System Responding Promptly to On-site Needs】

Integrated Technical Foundation: 【Advanced Miniaturization and Reliable Maintenance】 Provides the "compact charging circuit board" which is essential for realizing portability. The system, which handles everything from design and development to after-sales service in-house, allows for rapid reflection of on-site needs into products and supports business continuity with thorough maintenance even after introduction.

FAQ

What is the main advantage of this new portable EV charger compared to traditional ones?

The main advantage is that it eliminates the need for large-scale installation work, such as foundation construction. It can be used simply by plugging into a 200V outlet, and the charger can be brought to the vehicle, saving the hassle of moving the vehicle and improving on-site efficiency.

Does the portable charger require any electrical work?

If a 200V power outlet is available, no additional electrical work is required. However, if a 200V power source is not available, simple electrical work will be necessary.

What are the key contributions of Yamato Mobility and Gigawatts to this project?

Yamato Mobility contributes its deep on-site knowledge and expertise in logistics, resin manufacturing, and mobility operations to ensure practical usability and maneuverability. Gigawatts provides its advanced development technology, particularly its compact charging circuit board, and its integrated system for design, manufacturing, and after-sales service.

Is the portable charger designed for outdoor use?

Yes, the casing is made using proprietary resin molding technology, making it lightweight, durable, and resistant to impact and rust, suitable for continuous operation in harsh outdoor environments.

What is the goal of the joint development and demonstration testing?

The goal is to develop a practical portable Level 2 EV charger that maximizes on-site efficiency by eliminating installation hassles and the need to move vehicles, and to verify its effectiveness through demonstration testing.
