Overview
The JH-Insulation Breakdown Voltage Tester for Batteries is a precision high-voltage dielectric strength testing system engineered for quantitative assessment of electrical insulation integrity in electrochemical cells and battery modules. Operating on the principle of controlled DC or AC voltage ramping (per IEC 62660-1, UL 1642, and GB/T 31485), the instrument applies programmable voltage stress across electrode interfaces—such as separator-electrode assemblies or cell casing-to-terminal configurations—to determine the threshold at which dielectric failure occurs. Unlike generic hipot testers, this system integrates real-time current monitoring with sub-millisecond arc detection logic, enabling precise identification of onset-of-breakdown events critical for safety validation in lithium-ion, solid-state, and emerging battery chemistries. Designed for integration into R&D labs, QC environments, and third-party certification facilities, it supports both single-point pass/fail verification and full breakdown voltage distribution profiling under standardized environmental conditions.
Key Features
- Programmable voltage output range: 0–10 kV DC / 0–7 kV AC (rms), adjustable in 10 V increments with closed-loop feedback control
- Voltage measurement accuracy: ±1% of reading (traceable to NIST-calibrated reference standards)
- Current detection resolution: 1 µA, with automatic trip threshold configuration (0.1–20 mA) to prevent thermal runaway during test
- Dual-mode operation: Continuous ramp-up (0.1–5 kV/s) and step-stress protocols compliant with ASTM D149 and IEC 60243-1
- Integrated safety interlocks including door-switch monitoring, emergency stop circuitry, and ground-fault detection per IEC 61010-1 Class I requirements
- Front-panel touchscreen interface with multilingual support (English, Chinese, Japanese, Korean) and intuitive test sequence wizard
- Modular high-voltage transformer design with oil-immersed insulation for long-term stability and EMI suppression
Sample Compatibility & Compliance
The tester accommodates cylindrical (18650, 21700), prismatic, pouch, and custom-format battery cells up to 200 mm in height and 150 mm in width. Fixturing options include insulated electrode probes, spring-loaded contact plates, and fixture-mounted cell holders compatible with thermal chambers (−40°C to +85°C). All hardware meets RoHS 2.0 and REACH Annex XVII material restrictions. The system’s firmware and calibration documentation are structured to support GLP/GMP audit readiness, including electronic signature capability, user access levels (admin/operator), and audit trail logging per FDA 21 CFR Part 11 requirements. Test reports comply with ISO/IEC 17025 documentation standards and may be exported in PDF, CSV, or XML formats with embedded digital signatures.
Software & Data Management
JH-TestSuite™ v3.2 software provides comprehensive test automation, data visualization, and statistical analysis. It enables batch test scheduling, parameter template libraries (aligned with UN 38.3, GB/T 31485, and UL 2580), and Weibull distribution fitting for breakdown voltage reliability modeling. Raw acquisition data—including time-stamped voltage, leakage current, and derivative dI/dt—is stored in HDF5 format for traceability. Remote monitoring via Ethernet or optional Wi-Fi module allows integration into MES/LIMS platforms through OPC UA or Modbus TCP protocols. Calibration certificates include uncertainty budgets calculated per GUM (JCGM 100:2008), and all firmware updates are digitally signed and version-locked to prevent unauthorized modification.
Applications
- Quality assurance in battery manufacturing lines: final-cell dielectric screening prior to module assembly
