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.
