Overview
The HIOKI BT3563A is part of HIOKI’s BT356xA series, tailored for high-voltage battery packs up to 300 V DC. It uses the AC four-terminal method to simultaneously measure internal resistance (AC-IR) and open-circuit voltage (OCV), enabling faster throughput and reliable performance on production lines for large battery cells, modules, and packs. It offers high precision, noise immunity, long cable tolerance, robust interface options, and ease of system integration for automated operations.
Key Features
-
Simultaneous measurement of internal resistance and open-circuit voltage to avoid separate measurement steps.
-
Wide resistance measurement ranges: 3 mΩ, 30 mΩ, 300 mΩ, 3 Ω, 30 Ω, 300 Ω, 3 kΩ.
-
Open-circuit voltage measurement supports DC 6 V, 60 V, 300 V ranges.
-
High precision: 3 mΩ range resolution of 0.1 µΩ; 6 V range resolution down to 10 µV.
-
Fast response / sampling times: EX.FAST / FAST / MEDIUM / SLOW modes with response + sampling as low as around 10 ms total.
-
Strong static and noise resistance: withstands contact discharge ±30 kV (IEC 61000-4-2), tolerant of long or thin test leads.
-
Standard interfaces to connect into automated systems: LAN (TCP/IP), RS-232C, EXT I/O handler, analog output.
-
Comparator functions, statistics, and data storage: Hi/Lo thresholds, delay, averaging, memory for up to 30,000 data points, settings save/recall.
