Frequently asked questions
How does the company structure its operating businesses?
The group is organized around three primary business divisions, called the 'three business spears': Automotive Electronics, Energy Solutions, and Home Electronics. Supporting these are three manufacturing principles focused on quality, people, and supply-chain collaboration. The divisions are supplemented by an internal R&D unit, the Technology Innovation Incubation Room, which develops foundational technologies.
What proprietary technology does Diamond Electric Holdings develop in-house?
The company's internal Technology Innovation Incubation Room focuses on several core technology platforms. These include environmentally friendly combustion technology, insulated bidirectional power conversion technology, and advanced reactor technology. The group integrates these into products such as residential storage battery systems and a V2X-compatible onboard charger for vehicles.
