HIOKI BT3562A Battery HiTester (3 mΩ / up to 100 V) – Internal Resistance & OCV Measurement

Overview

The HIOKI BT3562A is an advanced battery tester designed for high-speed, high-accuracy measurement of battery internal resistance (AC-IR) and open-circuit voltage (OCV). It is part of HIOKI’s BT356xA series, engineered for fully automated production lines for xEV cells, modules, and mid-size battery packs under 100 V. The instrument offers excellent repeatability, fast response time, robust design against static and noise, and versatile interface options to integrate into automated test-and-inspection systems.

Key Features

• Simultaneous AC-IR & OCV measurement: measure internal resistance and open-circuit voltage at the same time without switching modes.

• Wide resistance measurement range: from 3 mΩ (with 0.1 µΩ resolution) up to 3 kΩ.

• Voltage measurement ranges: 6 V, 60 V, and up to 100 V DC for mid-size packs.

• High speed & fast sampling: response + sampling time designed for production line throughput. Modes include EX.FAST, FAST, MEDIUM, SLOW.

• Robust against static & noise: withstands ±30 kV contact discharge (IEC 61000-4-2), plus design features to limit error when using longer measurement leads or in noisy environments.

• Multiple interfaces for automation: LAN (TCP/IP), RS-232C, EXT I/O, analog output. Useful for PLC integration.

• Comparators, statistics & data handling: PASS/FAIL judgement, Hi/Lo voltage & resistance thresholds, up to 30,000 stored data points, settings save/recall.

Applications

This tester is suitable for:

• Quality control in manufacturing of xEV battery modules and packs under 100 V.

• End-of-line testing of battery cells and modules (OCV + internal resistance).

• Inspection of welding joint resistance, bus bar resistance in battery assemblies.

• R&D labs characterizing cell aging, quality, and batch uniformity.

• Automated production lines where throughput, stability, and integration are essential.
