New Hainan Client, Nanhai Net, Nanguo Metropolis Daily News on July 10 (Reporter Wang Hui) On July 10, Hainan Jinpan Intelligent Technology Co., Ltd. (hereinafter referred to as “Jinpan Technology“) “energy storage equipment” series of new The launch of the product and the world‘s first direct-mounted 35kV large-capacity energy storage equipment using all-liquid cooling and heat management technology was held in Guilin. At the meeting, the series of energy storage products such as medium and high voltage direct-mounted (cascade) energy storage systems and low-voltage energy storage systems were officially unveiled, which marked that the core energy storage products of Jinpan Technology have entered the commercialization process.
“Our country strives to achieve carbon peaking by 2030 and carbon neutrality by 2060. Green and low-carbon development of energy is the key.” At the press conference, Li Zhiyuan, chairman of Jinpan Technology, said that the transformation and upgrading of the energy industry is the realization of “double carbon”. The important path and inevitable choice of the goal. The power system will present a “double high” characteristic of high proportion of renewable energy and high proportion of power electronics, and will face a series of new challenges in terms of supply and demand balance, system regulation, distribution network operation, control and protection, and construction costs. Energy storage will play an important role in the load balancing of the new power system with new energy as the main body.”

The reporter from the new Hainan client learned at the scene that the medium and high voltage direct-mounted (cascade) energy storage system products released by Jinpan Technology are the first in the world to use full liquid cooling technology, which can be used on the power generation side, power grid side and industrial and commercial users. It is widely used in different application scenarios such as side.

Compared with low-voltage energy storage systems, medium and high voltage direct-mounted (cascade) energy storage system products do not require electrical equipment such as step-up transformers and DC combiner cabinets, which can effectively reduce the cost of energy storage system products and improve the efficiency of charge-discharge cycles. The land area is reduced, and the investment cost of energy storage projects is correspondingly reduced. “The use of full liquid cooling technology has lower power consumption and higher heat exchange efficiency, reducing the risk of battery thermal runaway.” Xi Xiaolong, general manager of Jinpan Technology Energy Storage Company, introduced.
Xi Xiaolong said that the low-voltage energy storage system products use battery active balancing technology, which can effectively increase battery life and improve safety. “The energy storage converter (PCS), a key component of energy storage system products, has obtained a test report issued by a third-party organization with relevant qualifications.”
The realization of sophisticated technology is not easy. According to Cai Xu, professor of Shanghai Jiaotong University and chief expert of Jinpan Technology, my country’s energy storage industry has entered a period of rapid development, “Due to the constraints of system security, my country’s large-capacity energy storage equipment has been developing slowly, and energy storage systems are urgently needed. The reform of the structure meets the challenge of large-capacity single-unit energy storage.” It is of great significance to successfully tackle and apply the high-voltage direct-mounted single-unit large-capacity energy storage technology.
Since the second half of last year, Jinpan Technology has started to invest in the research and development of high-end new energy storage equipment and the construction of digital energy storage equipment factories. Thanks to years of technical accumulation in power transmission and distribution and power electronic products, in less than a year, it has completed the research and development of the world‘s leading fully liquid-cooled 35KV high-voltage cascaded energy storage products, and successfully passed the model of the State Grid Electric Power Research Institute. Test certification. At present, the above products have achieved external sales orders, and the total amount of orders for medium and high voltage direct-mounted (cascade) energy storage system products is 134.6992 million yuan.
At the press conference, Jinpan Technology and China General Nuclear Power New Energy Investment Co., Ltd. also signed the delivery contract of “China Guangdong Nuclear Power Hainan Baisha Bangxi Energy Storage Project Full Liquid-cooled 12.5MW/25MWh 35kV High-Voltage Cascade Energy Storage System Equipment” to deepen the new energy storage system with practical actions. Energy and zero carbon industry cooperation.

It is worth mentioning that the digital factory of Jinpan Technology Guilin energy storage series products has been completed and put into production, which has laid the foundation for the efficient and high-quality delivery of equipment. This digital factory project is an upgraded version of the Haikou dry-type transformer digital factory that Jinpan Technology will put into production in 2020. After full production, it can achieve an annual output of 1.2GWh of energy storage products.
During the interview, the reporter from the New Hainan Client specially visited the digital factory of energy storage equipment, high-end dry-type transformer digital factory and complete digital factory built by Jinpan Technology in Guilin.
Walking into the gate of the digital factory base, there are only a few workers in the spacious and tidy workshop, and more intelligent equipment is operating in an orderly manner, and the automatic unmanned trolley shuttles back and forth to transport materials, and the production process and route data are displayed on the electronic screen. Clear and controllable… Many processes are full of high-tech content.
The reporter saw in the dry-type transformer digital factory that the factory integrates simulation, sensing technology, automated production lines, etc. with transformer design and manufacturing technology. Cut stacking, the finished product is automatically transferred and flipped, which subverts the traditional mode of manual stacking in the industry. The technician told reporters, “This equipment field is leading in China. After the overall transformation, the production capacity of the factory has increased by more than 100%, and the production efficiency and product quality have been greatly improved.”

The commissioning of the digital factory for energy storage equipment and the release of a series of products are an important step for Jinpan Technology to carefully lay out its energy storage business. The company said that the energy storage business will become one of the company’s new core businesses in the future.
