Tellhow Sci-Tech, also known as 泰豪科技 and Tellhow, is a Chinese commercial company established in July 1988. The company’s website presents its business around military equipment and emergency equipment, describing itself as a scaled enterprise in military equipment and a specialist in emergency equipment. Its listed-company identity is associated with 泰豪科技股份有限公司, whose Shanghai Stock Exchange ticker is 600590. The military-equipment business develops and services communications command systems, electro-optical detection products, and related military information technologies. The company’s published product portfolio includes communications and command systems, satellite navigation and vehicle electronics, electro-optical imaging and precision tracking equipment, military power stations, generator sets, military air-conditioning products, and ammunition-related products and systems. Its website also describes a research and industrialization collaboration with Tsinghua University in defense science and technology. In emergency equipment and power-related businesses, Tellhow describes work on intelligent emergency power and intelligent power distribution. Its energy-internet offering includes power trading, energy IoT, energy-efficiency management, microgrid control, intelligent operations and maintenance, and related services for government, utilities, parks, and commercial and industrial users. The power-grid business focuses on information systems and software, monitoring and data applications, distribution-network and dispatching systems, and related integration services. The company also identifies overseas power engineering as a platform for international development, covering engineering contracting, equipment supply, project investment, and integrated services across project stages. The official website lists contact locations in Nanchang, Jiangxi, and Beijing. It presents the company as active in China while also pursuing overseas power projects. The available evidence does not identify a founder, current controlling owner, or named executives, and does not establish a single parent company.

History

Tellhow Sci-Tech traces its corporate history to July 1988, when the company was established, according to the supplied Chinese Wikipedia evidence. The available materials do not identify the founders or provide a detailed account of the company’s earliest operations. They do establish that the company later became associated with 泰豪科技股份有限公司, described by that source as China’s first listed company in the smart-building electrical industry. The evidence does not specify the listing date, so no date is assigned here. The company’s current official presentation emphasizes two principal areas: military equipment and emergency equipment. In military equipment, Tellhow describes research, development, and services for communications command systems and electro-optical detection, alongside military information technology. Its product information spans command and communications systems, satellite navigation, vehicle electronics, electro-optical imaging, tracking and measurement products, military power systems, and air-conditioning equipment. The portfolio also includes ammunition and related systems. The official site describes a joint research institute with Tsinghua University, framing the collaboration around defense research and production, industry-academia-research cooperation, talent development, technology commercialization, and development of needed products and projects. The emergency-equipment business focuses on intelligent emergency power and intelligent power distribution. The company also presents an energy-internet business serving government, the power sector, parks, and industrial and commercial customers. Its described services include electricity sales and trading, trading simulation, energy-efficiency management, microgrid control, intelligent operations and maintenance, and energy-related information services. In power-grid products, it highlights information systems and software, monitoring and data applications, distribution-network operations and management systems, dispatching and control applications, and system-integration services. The site further describes overseas power engineering as a channel for international development, with activities in engineering contracting, equipment supply, investment, and integrated project services. The official website gives a Nanchang, Jiangxi contact address for the smart/emergency-equipment page and a Beijing contact address for the military-equipment page. These references document operating contacts rather than establishing a definitive corporate-headquarters structure. The supplied evidence identifies the company as listed under ticker 600590 but does not provide current ownership, a controlling shareholder, leadership names, or a chronology of acquisitions and management changes. It also contains no substantiated company scandals or dated recent corporate announcements. Accordingly, the history here is limited to the dated founding fact and the business development and capabilities stated in the official materials.
