From Installation to Placement: Yamato Mobility & Mfg. and Jigowatts Begin Joint Development of Portable AC EV Chargers

Yamato Mobility & Mfg. Co., Ltd. (Headquarters: Kawagoe City, Saitama Prefecture; Representative Director CEO: Akihisa Suzuki; hereinafter "Yamato Mobility"), which develops resin, logistics equipment manufacturing and sales, and mobility businesses, and Jigowatts Co., Ltd. (Headquarters: Chuo-ku, Tokyo; Representative Director: Tomoki Shibata; hereinafter "Jigowatts"), which handles EV charger design, manufacturing, sales, and after-sales service consistently, are pleased to announce the start of joint development and demonstration experiments for portable AC EV chargers.

Background of the Birth of Portable EV Chargers: Eliminating the hassle of moving vehicles and maximizing on-site efficiency

Conventional fixed AC chargers require extensive installation work, such as foundation work and anchor fixing to the ground. Furthermore, vehicles need to be moved to a specific space for charging, and especially in time-sensitive operational sites with limited space, this "vehicle swapping work" was a major factor in reducing operational efficiency. The product jointly developed by both 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 revolutionary idea enables efficient energy supply without interrupting current workflows. (*Simple electrical work is required separately if a 200V power source is not available)

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

This project is a practical value creation project where Yamato Mobility's "on-site capabilities," which are well-versed in on-site challenges, and Jigowatts' "vertically integrated technology" are highly integrated.

[Yamato Mobility: Synergy of 3 Business Units that Shape On-site Knowledge]

Logistics Business Unit: [Pursuit of overwhelming maneuverability] Realizes "smooth entry into narrow vehicle spaces," which was difficult with fixed or conventional portable chargers, with dolly technology developed from a professional perspective. Its light operability, manageable with one hand, enables efficient operation in limited spaces.

Resin Business Unit: [Lightweight, highly durable, high-quality casing] Develops a dedicated casing that protects precise charging boards using proprietary resin molding technology. Lighter than metal, resistant to impact and rust, it provides 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 at the forefront of actual vehicle operations. It refines practical solutions from the perspective of "how to operate to best assist the site."

[Jigowatts: "Compact Board" and Integrated System that Responds Immediately to On-site Needs]

Integrated Technology Platform: [Advanced miniaturization and reliable maintenance] Provides a "compact charging board," which is essential for realizing portability.

With an integrated system that handles everything from design and development to after-sales service in-house, it quickly reflects on-site needs into products and supports business continuity with thorough maintenance even after introduction.
