Hubei Changhai New Energy Technology Co., Ltd.

The 712th Research Institute of China Shipbuilding Industry Corporation is located in Wuhan, a city known as the thoroughfare to nine provinces, near the scenic South Lake of Wuchang. It was established in April 1963 and is a specialized research institute in China for ship electric propulsion systems and devices. It is a national key research institute, with main specialties including electric propulsion systems and control, motors, switchgear, power electronics, chemical power sources, and insulating chemical materials.
Hubei Changhai New Energy Technology Co., Ltd. (hereinafter referred to as Changhai New Energy Technology) was established in March 2006 and is affiliated with the 712th Research Institute of China Shipbuilding Industry Corporation. It is a high-tech enterprise developed on the basis of the military and civilian product development work of the 712th Research Institute over more than 20 years of reform and opening up, inheriting the fine tradition of product quality first and utilizing technology. The company is mainly engaged in the research and development, production, sales, and technical services of chemical power sources and insulating chemical products. The company's products include both military and civilian products, contributing to the construction and service of the shipbuilding industry as well as to the development of the national economy.
In the mid-1980s, the company took the lead in developing fully sealed valve-regulated lead-acid battery technology in China. In 1992, this technology was listed by the State Science and Technology Commission as a project in the "Key Promotion Plan for Scientific and Technological Achievements"; after years of effort, we have developed dozens of varieties in three major series: GFM, FM, and railway. The products are widely used in fields such as electric power, communications, railways, ships, and uninterruptible power supplies, and have won user praise for their excellent product quality and good reputation.
As an upgraded product, valve-regulated sealed lead-acid batteries have a wide range of applications. In terms of power batteries, our company is a leading developer of power batteries in the shipbuilding industry. Since the "Ninth Five-Year Plan", the company has applied new design concepts, developed multiple new technologies, and developed multiple types of high-performance batteries that have been equipped and used by the military. The company's military products have long led the research of domestically advanced power batteries and motor insulation structures. The technical level has been recognized by all parties, and the products led by the company have been equipped by the military and highly praised, with their technical level reaching international advanced standards.
In terms of insulating chemicals, the company has been committed to the design of various motor insulation structures and the research and development of various heat-resistant, voltage-resistant, and special environment-resistant insulating materials for many years. It has successfully designed insulation structures for a series of propulsion motors and charging generators, insulation structures for kilovolt-level variable-frequency adjustable-speed synchronous motors, and insulation structures for other high-specification permanent magnet motors and high-temperature superconducting motors. At present, the company's insulation products cover Class B, F, H, and C insulating varnishes, Class F and H mica tapes, mica foils, and other mica composite products, as well as polyurethane chemical materials. Many products have reached the level of similar foreign products and filled domestic gaps.
