The project is a multi-line manufacturing system with a designed annual capacity in the GWh range. It covers the full production sequence, including electrode preparation, cell assembly, formation, and automated testing, with line-level control and production data managed through an integrated PLC and SCADA architecture.
The scope goes beyond conventional machine supply. TOB NEW ENERGY designed, manufactured, integrated, and validated the production line, then supported installation, commissioning, and production ramp-up at the customer's overseas site. The project illustrates how the company now operates: as a turnkey battery manufacturing engineering partner whose work covers process planning, equipment selection, production-line integration, factory acceptance testing, site acceptance support, and production ramp-up.
Because the customer's identity, plant location, and certain production parameters are protected by confidentiality agreements, specific figures are not disclosed in this announcement.

A GWh-Scale Battery Manufacturing Project
Large battery programs differ from laboratory or pilot projects in several structural ways: the number of machines involved, the complexity of material flow between stations, and the level of automation required to hold process consistency across millions of cells.
This project was designed as an integrated manufacturing system rather than a set of independent lines. Electrode production equipment, cell assembly stations, formation and aging systems, and testing equipment were engineered together so that line speed, buffer capacity, and process parameters remain synchronized from coating through final grading. The automation layer collects data at each critical step, allowing operators to track production in real time and maintain traceability from material batch to finished cell.
At GWh scale, this integration is not optional. A single mismatch between coating line speed and downstream drying or calendering capacity can create bottlenecks that reduce effective output far below the line's nominal capacity. The project's engineering effort therefore started at line architecture and production flow design, not at individual machine specification.

FAT and Engineering Validation
FAT is the formal verification stage performed at the supplier's manufacturing site before shipment. During FAT, the customer's representatives and the supplier jointly verify that each machine, and the line as a system, meets the contract specification under controlled conditions.
For this GWh project, the FAT program covered a broad set of acceptance criteria:
•Mechanical accuracy, alignment, and long-run stability of individual equipment
•Electrical installation quality, control response, and safety protection
•Automation interlocking across material transfer and process stations
•Communication integrity between PLCs, sensors, and the SCADA layer
•Data acquisition accuracy for production parameters and traceability records
•Safety functions and emergency-stop behavior under simulated fault conditions
Because the contract involved production lines rather than single machines, FAT also included integrated validation across stations. Electrodes, cells, and test samples were moved through multiple linked processes to confirm that the equipment could operate as one continuous system, not merely as separate machines that each passed individual tests.
FAT results were checked against the customer's approved technical specifications and the acceptance criteria defined in the project agreement. Every verification step produced records that became part of the formal handover documentation.

From FAT to Overseas Commissioning
The distinction between FAT and site work matters in international battery projects. FAT confirms that equipment is ready to ship. It does not confirm that a line will perform inside a customer's building, connected to that customer's utilities, environment, and operating team.
After FAT was successfully completed at TOB's manufacturing facility, TOB's core engineering team continued to support the project on-site overseas for more than three months during installation, commissioning, site acceptance testing (SAT), and production ramp-up.
During this phase, the team's responsibilities included mechanical installation and alignment, connection and tuning of electrical and automation systems, validation of material flow under production conditions, and coordinated testing with the customer's process and quality teams. SAT is a different discipline from FAT: equipment must now perform with real production material, in real ambient conditions, at real line speed, and under the supervision of operators who will run it every day.
The ramp-up period then moves the line from initial production to stable output. Issues that appear during ramp-up are rarely about single-machine performance. More often they involve throughput balancing, parameter drift over consecutive shifts, defect detection thresholds, and the speed at which operators learn to respond to line events. The presence of an experienced commissioning team during this window is one of the main reasons projects reach stable production on schedule.

Engineering Across the Battery Production Line
A turnkey lithium-ion line is best understood as a chain of engineering disciplines rather than a collection of machines.
The process chain begins with slurry mixing, where material rheology and dispersion quality determine everything that follows. Coating and drying control electrode weight, thickness, and adhesion. Calendering sets electrode density. Slitting and notching define dimensional consistency. Assembly determines alignment, sealing quality, and mechanical integrity. Formation builds the solid electrolyte interface that governs cycle life, and testing confirms that cells meet specification before shipment.
Each step requires equipment designed for its process, but the engineering value lies in the connections between steps. A coater that produces excellent electrode on its own is of limited value if the drying profile upstream or the calendering pressure downstream is not matched to the coating formulation. In this project, TOB's process and automation engineers worked across the full chain to define parameters at the system level rather than at the level of individual machines.
Factory planning matters equally. Line layout, material flow, buffer sizing, dry-room conditions, and utility connections all influence whether nominal capacity becomes real output. These decisions are made before equipment arrives, which is why turnkey engineering begins with process design and plant planning rather than equipment procurement.

Managing Integration Risk at GWh Scale
Large-scale battery lines fail most often at the interfaces: between machines, between process steps, and between supplier knowledge and customer operations. Naming these interfaces makes the risk manageable.
Typical integration points on a GWh-scale line include:
•Mechanical interfaces between material handling and process equipment
•Electrical and safety interfaces across independently supplied stations
•PLC communication between machine-level controls and line-level supervisory systems
•MES or SCADA integration for production data and traceability
•Material transfer between electrode production, assembly, and formation areas
•Process parameter synchronization across linked equipment
•Quality feedback loops that connect inline inspection results to line control
•Operator training and shift-to-shift consistency during ramp-up
In a multi-vendor project, responsibility for these interfaces is often divided, which makes them the most common source of schedule delay. In this project, TOB held responsibility across equipment supply, automation integration, and commissioning. That structure does not remove every risk, but it ensures that interface issues are resolved by the organization that owns the design decisions, rather than debated between separate suppliers on site.

Expanding Into Turnkey Battery Manufacturing Engineering
The GWh project reflects a broader shift in TOB NEW ENERGY's role. The company continues to supply individual machines, laboratory systems, and materials, but it is increasingly engaged as a partner for complete manufacturing capacity: process definition, line architecture, equipment manufacturing, automation, validation, and commissioning support.
This direction builds on engineering foundations that predate the current company structure. TOB NEW ENERGY was established in 2012, and its founding team entered the battery equipment industry in 2002. The company's engineers have worked across laboratory research, pilot-line validation, and production-scale projects, which gives its line design work a practical basis: equipment is specified by people who have operated comparable processes, not only designed them.
The company's turnkey battery production line projects cover coin cell laboratory lines, cylindrical and pouch cell pilot lines, and production lines for cylindrical, pouch, and prismatic formats, as well as sodium-ion and supercapacitor systems. The integration capability demonstrated in this GWh project extends the same engineering model to larger manufacturing environments.

Technology Consulting Beyond Equipment Supply
One notable element of this project is the expansion of TOB's consulting role beyond the equipment it supplied. The engagement included technology consulting on process planning, equipment configuration, and production readiness, helping the customer translate cell and process requirements into an operational factory.
For overseas customers entering or expanding battery manufacturing, this type of consulting reduces risk in two ways. First, it provides access to process knowledge that is normally accumulated only through years of operating production lines. Second, it creates a single point of accountability: the same organization that advises on process design also builds the equipment and supports commissioning, so recommendations are tested against real machine behavior rather than left as abstract advice.
The distinction is important. A consultant who does not supply equipment can give recommendations without responsibility for their outcome. An equipment supplier who does not understand process engineering can deliver machines without knowing whether they will produce the customer's target cell. The combination of both capabilities, structured as engineering services rather than as sales support, is the direction the company intends to continue developing.

Global Battery Manufacturing Experience
The GWh project adds another reference point to TOB NEW ENERGY's international portfolio, which already spans laboratory lines, pilot lines, and production-scale systems delivered to customers in Europe, the United States, India, Korea, Southeast Asia, Australia, and South America.
The company has designed and delivered more than 200 battery and supercapacitor production lines, ranging from research-scale configurations to industrial production facilities. Recent deliveries include sodium-ion laboratory lines, cylindrical and pouch pilot lines, and supercapacitor production systems, alongside the GWh-scale lithium-ion program described here.
For customers planning new battery capacity, the practical value of this history is reference evidence. Equipment claims can be checked against delivered projects, commissioning methods can be reviewed through past engagements, and line concepts can be compared with systems already running in commercial use.
