Daihen

Daihen is a Japanese industrial equipment company operating across three areas presented on its official website: Energy Management, Factory Automation, and Material Processing. Its portfolio includes equipment for electric power distribution and transformation, renewable-energy and storage applications, electric-vehicle charging, industrial robotics and automated transport, plasma power, welding, and cutting. The company website identifies the corporate entity as 株式会社ダイヘン and presents product, company, business, investor-relations, sustainability, and recruitment information. In Energy Management, Daihen lists transformers, power receiving and substation systems, equipment for renewable generation and storage, V2X systems, lightning-protection products, and EV charging systems. Its charging range includes conventional and rapid chargers as well as wireless charging. The official product page describes chargers for commercial and fleet settings, including models with external control of charging power and a rapid-charging product with a reservation function. Factory Automation offerings include industrial robots, robot peripherals, clean and wafer-transport robots, autonomous transport vehicles, and wireless charging systems for automated guided vehicles. In Material Processing, the company lists plasma-generation power supplies and automatic matching units, welding and cutting machines, torches, wire feeders, and related equipment. These product categories position Daihen as an industrial technology supplier serving power infrastructure, manufacturing automation, and joining and cutting processes. The supplied official-site material does not establish the company’s founding date, founder, headquarters, ownership structure, listing status, or the geographic extent of its markets. Those details are therefore left unspecified here. The site provides corporate information and domestic and overseas affiliate sections, but their presence alone does not establish particular operating locations. Daihen’s current public-facing portfolio and corporate information are available through its Japanese-language website.

Daihen’s official website presents the company as a Japanese industrial equipment business with a portfolio organized into Energy Management, Factory Automation, and Material Processing. The supplied company-information page links to corporate philosophy, a message from the top executive, an executive list, company overview, company history, governance, domestic locations, and domestic and overseas affiliates. The page does not itself provide the details contained in those sections, so this dossier does not assign a founding date, founder, or specific headquarters. The company’s current product catalog shows a broad industrial scope. Energy Management products include industrial and large transformers, power receiving and substation systems, equipment for renewable generation and storage, V2X systems, lightning-protection products, and EV charging equipment. The charging catalog covers ordinary, rapid, and wireless charging, including the D-Broad EV wireless charging system. The company describes wireless charging as supporting charging while a vehicle is parked and also presents a system for charging while driving. Factory Automation products include industrial robots, peripheral fixtures and sensors, welding torches and power sources, clean transport robots, wafer and flat-panel transport robots, autonomous transport vehicles, and wireless charging for automated guided vehicles. Material Processing includes plasma-generation power supplies and automatic matching units, welding and cutting machines, torches, wire-feeding equipment, and related products. The catalog also names Welbee Co-R, a dissimilar-material joining process, and copper-alloy 3D additive manufacturing technology. The official site’s EV charging information documents product and application development through dated notices. In September 2024, Daihen announced that a social implementation demonstration using its D-Broad EV system had been selected for a Japanese Ministry of the Environment program related to transport-sector decarbonization. In January 2025, the page listed an announcement of a NEDO Energy-Saving Technology Development Award Best Collaboration Award. These notices indicate public activity around EV charging and energy-saving technology, without establishing broader commercial outcomes. The supplied homepage also displays notices dated in 2026, including a planned exhibition and the market launch of an autonomous robot named VIVACE. Because the provided material does not clarify the timing or subsequent status of those announcements, they are not treated here as completed historical events. Overall, the available evidence supports a description of Daihen as an active, diversified industrial equipment company; further corporate-history, ownership, and leadership details require the linked company-information records.
