Pilot Line Prismatic Battery Automatic Electrolyte Filling Machine

Product Overview

This system is an automatic electrolyte filling machine engineered for precise, quantitative filling of prismatic power batteries on pilot production lines. It combines fixture-based battery positioning, vacuum-assisted electrolyte injection, nitrogen filling and dwell stages in one controlled workflow. The result is a practical production tool for operations that require efficient filling, straightforward manual handling, and stable repeatability across continuous shifts.

The equipment is designed for prismatic battery manufacturing processes where electrolyte dosing directly affects downstream cell consistency. It is suited to pilot-scale development, process validation, and pre-production work involving power-cell formats. One operator manually loads and unloads fixtures while the unit automatically clamps, evacuates, fills, and cycles the prepared fixture through nitrogen and dwell positions.

Built around a defined vacuum source, controlled pneumatic supply, mechanical transmission, and an operating system, this unit is configured for demanding routine operation. Its maximum utilization rate is at least 95% based on continuous 24-hour production statistics, while its dosing precision target supports controlled, repeatable electrolyte filling under the stated test conditions.

Key Features

• Vacuum-Assisted Filling Method: The system first evacuates the cell and then injects electrolyte using an absorption-based process. This sequence supports controlled filling of prismatic power batteries within a repeatable automated cycle.

• Precision Quantitative Dosing: Filling accuracy is specified at +/-3 per thousand. The stated verification method uses empty shells, one fill per filling head, one sampling event, and 20 samples per filling head.

• Twelve-Position Fixture Capacity: The supplied fixture is based on a battery measuring 207 mm high, 135 mm wide, and 29 mm thick, with an electrolyte amount of 300 g. One fixture can load or unload 12 pieces at a time, supporting efficient batch handling by a single operator.

• Automated Clamp Positioning: After manual fixture loading, the fixture is automatically positioned and clamped before the vacuum and filling operation begins. This mechanical sequence provides a consistent operating basis for each cycle.

• Configurable Process Stages: Vacuum intensity, pressure-holding time, standing time, and the number of cycles can be set for the vacuum, nitrogen-fill, and dwell sequence. Nitrogen requirements are determined by the customer's process requirements.

• Pilot-Line Throughput: Maximum efficiency is 1 PPM, with actual output dependent on cell dimensions, cell capacity, and electrolyte weight. Larger electrolyte fill quantities reduce achievable efficiency, enabling buyers to evaluate capacity against their specific cell process.

• Continuous-Production Focus: The equipment is specified for a utilization rate of at least 95%, calculated from continuous 24-hour production data. This makes uptime a defined purchasing consideration rather than an unspecified operating claim.

• Defined Utility Interface: The unit operates from AC220V power with a 1.5KW load, requires compressed air at 0.4-0.6Mpa and 100L/min flow, and uses a vacuum source rated at -0.095Mpa. Clear utility requirements simplify pilot-line installation planning.
