Battery Washing Test Machine Yuelian YL-XD-01

Overview

The Yuelian YL-XD-01 Battery Washing Test Machine is an engineered test apparatus designed to evaluate the structural integrity and sealing performance of primary and rechargeable batteries under simulated washing or immersion conditions. It operates on a standardized mechanical agitation principle—employing controlled rotational tumbling within a temperature-regulated aqueous bath—to replicate real-world exposure scenarios such as accidental laundering, industrial cleaning processes, or post-manufacturing rinse validation. This device supports compliance-driven verification per international safety and reliability standards including IEC 62133-2 (secondary cells and batteries), UN 38.3 Section 38.3.4 (mechanical stress testing), and GB/T 18287–2013 (Chinese national standard for lithium-ion batteries). The system is not intended for electrochemical characterization but serves as a dedicated mechanical environmental stress tester in battery qualification workflows.

Key Features

• Programmable tumbling cycle control with adjustable rotation speed (0–60 rpm), duration (1–999 min), and pause intervals to accommodate diverse battery form factors and test protocols.
• Stainless-steel test chamber (304 grade) with sealed lid and integrated water-level sensor to prevent overflow and ensure consistent immersion depth during operation.
• Digital PID temperature controller maintaining bath temperature from ambient to 45 °C ±1 °C, enabling evaluation across mild to moderately elevated thermal conditions.
• Integrated safety interlock system that halts rotation and disables heating if the chamber lid is opened mid-cycle or water level falls below operational threshold.
• Modular tray design accommodating cylindrical (AA, AAA, 18650), prismatic (e.g., 503048), and pouch-type cells—up to 20 units per batch depending on dimensions.
• Compliance-ready documentation support: test log export (CSV), timestamped cycle records, and configurable pass/fail criteria based on visual inspection outcomes (e.g., leakage, swelling, electrolyte seepage).

Sample Compatibility & Compliance

The YL-XD-01 accepts commercially available consumer and industrial battery formats ranging from 1.5 V alkaline to 3.7 V Li-ion, including Ni-MH, Li-Po, and solid-state prototypes at pre-commercial stage. All samples must be fully assembled, sealed, and in final packaging configuration prior to testing. The machine does not support open-cell or unpackaged electrode stacks. Its operational envelope aligns with functional requirements outlined in ISO/IEC 17025-accredited laboratories performing battery safety validation. While the unit itself is manufactured in Guangdong, China, its mechanical architecture and control logic are structured to meet traceability and audit readiness expectations under GLP and GMP-aligned quality systems—particularly where washing resistance is a defined release criterion in OEM supply agreements.

Software & Data Management

The YL-XD-01 utilizes embedded firmware without cloud connectivity or proprietary desktop software. All operational parameters are configured via a front-panel LCD interface with membrane keypad navigation. Cycle execution logs—including start time, total runtime, average RPM, peak bath temperature, and manual pass/fail annotation—are stored locally in non-volatile memory (retention >10 years). Data export is performed via USB-A port using FAT32-formatted flash drives; exported CSV files contain ISO 8601 timestamps, cycle ID, and operator-assigned batch identifiers. Audit trails comply with basic 21 CFR Part 11 principles through immutable timestamping and absence of post-hoc editing capability—suitable for internal QA documentation and third-party certification submissions where electronic record integrity is required.

Applications

• Pre-shipment validation of battery housing seal integrity for wearable electronics and medical devices subjected to routine cleaning protocols.
• Root cause analysis of field failures linked to moisture ingress after incidental exposure to detergents or tap water.
• Design verification testing during NPI (New Product Introduction) of waterproof enclosures for power tools and outdoor IoT sensors.
• Supporting technical documentation packages for CE marking (under EN 62133) and KC certification (Korean Agency for Technology and Standards).
• Internal QC screening for battery pack integrators evaluating supplier consistency in gasket compression and weld seam reliability.

FAQ

Does the YL-XD-01 perform electrical testing during washing cycles?
No. It is a purely mechanical and thermal stress apparatus. Voltage, capacity, or impedance measurements require integration with external bench instrumentation.

Can the unit operate with solvents other than deionized water?
Only aqueous solutions compatible with 304 stainless steel and EPDM seals are permitted—e.g., mild detergent solutions (pH 6–8) per IEC 62133 Annex E. Aggressive solvents (acetone, ethanol >20%, strong acids/bases) are prohibited.

Is calibration certificate included with shipment?
A factory-verified temperature and timer calibration report is supplied. Full ISO/IEC 17025 calibration must be performed by an accredited third-party lab per user-defined frequency (typically annually).

What maintenance is required?
Monthly cleaning of chamber interior and drain filter; biannual inspection of door gasket elasticity and motor coupling integrity; annual verification of thermal sensor drift using NIST-traceable reference thermometer.
