Overview
The Jianhu JH-Series Dielectric Breakdown Tester is an industrial-grade high-voltage testing instrument engineered for precise measurement of dielectric strength and insulation breakdown voltage in electrochemical cells—particularly lithium-ion, solid-state, and pouch-type batteries. It operates on the principle of controlled voltage ramping across a defined electrode gap under standardized atmospheric or inert-gas conditions, detecting the critical electric field threshold at which insulating materials (e.g., separators, electrolyte membranes, or cell casings) undergo irreversible electrical failure. Designed in accordance with IEC 62368-1, UL 1642, and GB/T 31241 safety test protocols, this system supports both research-grade characterization and production-line quality assurance workflows. Its architecture integrates galvanically isolated high-voltage output stages, real-time leakage current monitoring (<1 µA resolution), and programmable dwell time control to ensure repeatable, traceable, and auditable test execution—essential for ISO/IEC 17025-accredited laboratories and GMP-compliant battery manufacturing facilities.
Key Features
- Programmable voltage ramp modes: continuous linear ramp, stepwise incremental ramp, and hold-at-threshold testing—configurable per ASTM D149 and IEC 60243 standards.
- Wide output range: 0–10 kV DC / 0–5 kV AC (rms), adjustable in 10 V increments; calibrated accuracy ±1% of full scale with NIST-traceable certification options.
- Dual-channel real-time acquisition: simultaneous sampling of applied voltage and leakage current at ≥10 kHz sampling rate, enabling microsecond-level breakdown event capture.
- Integrated safety interlocks: automatic shutdown upon ground fault detection, overcurrent tripping (<5 mA threshold), door-open sensing, and emergency stop circuit compliant with EN 61010-1.
- Modular electrode fixtures: interchangeable stainless-steel needle, sphere-to-sphere, and parallel-plate configurations for flexible sample mounting—compatible with cylindrical, prismatic, and pouch cell formats.
- Robust enclosure: IP2X-rated flame-retardant ABS housing with reinforced HV shielding, CE-marked and RoHS-compliant construction.
Sample Compatibility & Compliance
The JH-Series accommodates battery samples ranging from 18650 cylindrical cells to large-format EV modules (up to 500 mm × 300 mm footprint). Electrode spacing is manually adjustable from 0.1 mm to 25 mm, supporting both thin-film separator evaluation and full-cell casing integrity verification. All test procedures align with internationally recognized regulatory frameworks—including UN 38.3 Section 3.3.1.5 (external short-circuit simulation), IEEE 1625/1626 (rechargeable battery safety), and China’s GB/T 36276–2018 for power battery safety requirements. Optional inert-atmosphere glove box integration enables testing under argon or nitrogen environments—critical for air-sensitive solid electrolytes. Documentation packages include full traceability logs, calibration certificates, and test report templates pre-formatted for FDA 21 CFR Part 11 electronic signature readiness.
Software & Data Management
The embedded Windows-based control software (JH-TestSuite v4.2) provides intuitive test sequence programming, live waveform visualization, and automated pass/fail classification based on user-defined voltage-current thresholds. All raw data—including time-stamped voltage, current, temperature (via optional PT100 input), and environmental humidity—are stored in ASCII CSV and XML formats for third-party analysis (MATLAB, Python Pandas, LabVIEW). Audit trails record operator ID, timestamp, parameter changes, and system events—fully compliant with GLP and ISO 17025 documentation requirements. Remote operation via Ethernet or RS-232 allows centralized fleet management across multi-site QA labs; API support enables integration into MES/QMS platforms such as Siemens Opcenter or ETQ Reliance.
Applications
- R&D validation of novel separator coatings (e.g., Al₂O₃, PVDF-HFP) under accelerated voltage stress.
- Batch release testing of commercial LiCoO₂ and NMC cathode cells prior to module assembly.
- Failure mode analysis during thermal runaway propagation studies (coupled with external calorimetry).
- Qualification of encapsulation materials for flexible printed batteries and micro-energy harvesters.
- Supplier qualification audits requiring documented dielectric performance history per AIAG CQI-17 guidelines.
