Recently, Shenzhen Bluesea Intelligent Manufacturing Technology Co., Ltd. (“Bluesea Intelligent”) successfully delivered a 26 PPM ESS module automated production line built for Ginlong Technologies. Ginlong Technologies (Solis; SZSE: 300763) is a globally leading inverter manufacturer and energy storage system solution provider. It ranked among the global top three in PV inverter shipments for three consecutive years from 2022 to 2024, with products sold in more than 100 countries and regions. The choice by a leading customer demonstrates Bluesea Intelligent’s full-line delivery capability in ESS module PACK automation equipment. The line is fully compatible with mainstream cells including 100Ah, 314Ah, 392Ah, 587Ah, 628Ah and 684Ah. It primarily produces 1P104S and 1P52S modules and is also compatible with other mainstream module processes. Actual line throughput reaches 26 PPM, with reserved space for retrofit to 1,175Ah large cells, providing a replicable benchmark for ESS industry production line construction under the “mass-produce one generation while pre-developing the next” model.

As a national-level specialized, refined, distinctive and innovative “Little Giant” enterprise, Bluesea Intelligent was founded in 2016. It focuses on the R&D and manufacturing of ESS battery module PACK automated production lines, lean process consulting and MES construction. With full-line equipment as its core, it is building an ESS PACK ecosystem service alliance and is regarded by the industry as a leading company representing the “last mile” of intelligent lithium battery manufacturing.

Full Compatibility with 1,000Ah-Class Cells: Production of 1,175Ah and Below

Bluesea Intelligent’s ESS module PACK automated production line supports full-specification production of 1,000Ah-class (1,175Ah) and below cells available on the market. The main compatible specifications are as follows:

Note: The dimensions in the table above are public reference specifications of mainstream ESS cells on the market (subject to actual specifications from each cell manufacturer). Bluesea Intelligent’s production line can customize fixtures and process recipes according to customers’ actual cell dimensions to achieve rapid changeover.

Through modular fixture design, servo flexible positioning and parameterized process recipes, Bluesea Intelligent helps ESS companies quickly switch between cells of different capacities and dimensions within cell iteration cycles, without reinvesting in an entire production line. In the Ginlong Technologies project, for example, the line is compatible with 100Ah, 314Ah, 587Ah and 684Ah cells and reserves space for 1,175Ah upgrades. Changeover time for the cell section and module section is no more than 24 hours, and changeover time under existing recipes is no more than 4 hours. One-click changeover is supported, significantly improving equipment reuse rate and overall benefits.

12–48 PPM Full Capacity Coverage, Mixed-Line Production of Prismatic and Cylindrical Cells

In terms of line takt time, Bluesea Intelligent can provide capacity configurations across the full 12–48 PPM range, covering different needs from small-batch flexible lines for commercial and industrial (C&I) energy storage to large-scale mass production lines for utility-scale energy storage. The 26 PPM module line for Ginlong Technologies adopts a flexible modular design, with overhead logistics on some material flow routes and reserved room for capacity expansion. In the future, with additional configurations and machines, capacity can be expanded upward to 36 PPM. The line’s first-pass yield is no less than 99%, OEE no less than 80%, and line utilization rate no less than 90%. It covers the full process, including cell loading, barcode scanning and OCV testing, plasma cleaning, module stacking, CCS welding, PACK assembly, EOL testing, charge/discharge aging, and finished product packaging.

Ranked No. 1 in Shipments, Serving More Than 300 Customers

According to industry sources, Bluesea Intelligent ranks first in the industry in both the shipment volume of automated production lines for large-cell ESS module PACK and the number of customers served for ESS battery module PACK automation equipment. To date, Bluesea Intelligent has served more than 300 customers, including many leading domestic ESS companies such as CATL, EVE Energy, Ganfeng Lithium, Tianjin Lishen, Youpai Energy, Growatt, Infore Environment, Huayou Energy, Midea Hiconics, Hongying Co., Ltd., Chuangming Battery, Wotaitong, Changhong Sanjie, EcoFlow, Hello Tech, Daqin Digital Energy, Lvda Energy, Yongtai Digital Energy, and battery manufacturers. Its products and production lines are deployed across major new energy industry clusters nationwide.

Bluesea Intelligent is also actively promoting equipment exports. In just a few years, its new energy battery module PACK lines have been exported to the United States, Germany, the United Kingdom, Saudi Arabia, India and other countries. It has established overseas branches and after-sales service teams to ensure smooth project delivery and implementation overseas.

Three Bases in Synergy: Shenzhen Headquarters + Ninghai and Jiangmen Manufacturing Bases

The continuous improvement of capacity and delivery capability is backed by Bluesea Intelligent’s “three bases” strategic layout: Shenzhen headquarters serves as the R&D and operations center; the Ninghai production base was established and put into operation early on; the two bases continuously deliver mature production lines. The Jiangmen production base, located in Zhongxing Energy Storage Smart Valley, Muzhou Town, Xinhui District, Jiangmen City, was recently completed and put into operation, further enhancing the company’s local delivery and rapid response capabilities in the Greater Bay Area and South China.

Looking ahead, Bluesea Intelligent aims to become the first listed company in the ESS module PACK automated production line niche. Driven by both capital and industry, it will continue to increase R&D investment and capacity building to help more ESS companies achieve high-quality, high-efficiency scaled production.

Industry analysts believe that competition in the ESS module PACK automation equipment sector has shifted from standalone equipment to all-round competition in full-line solutions, delivery capability and service systems. With years of deep industry experience, full-stack line capabilities and full compatibility with 1,000Ah-class cells, Bluesea Intelligent is expected to continue expanding its lead in the era of large-cell energy storage.
