Description
Overview
The HIOKI BT3564 is engineered for high-voltage battery pack inspection, combining high precision, wide dynamic range, safety features, and automation-friendly interfaces. It is designed to meet the rigorous demands of production, shipping/receiving, and quality control for EV/PHEV, residential battery storage, and other applications where battery pack voltages are high (up to 1000 V). The unit uses a four-terminal 1 kHz AC method for resistance measurement (AC-IR) while simultaneously measuring DC voltage (open-circuit voltage, or OCV). It includes functions to reduce spark discharge, which is critical in high-voltage environments.
Key Features
-
High voltage capability: direct measurements up to 1000 V DC, suitable for EV/PHEV battery packs and high-voltage battery modules.
-
Wide internal resistance range: from 0.1 mΩ up to 3 kΩ, covering both very low resistance (pack total / bus bar) to higher resistance for smaller sub-modules.
-
Voltage measurement range: DC voltage measurement up to 1000 V, with multiple ranges.
-
Spark discharge reduction: to improve safety when contacting high-voltage battery terminals.
-
Analog output function: for resistance measurements, allowing long-term monitoring via data loggers or recording devices.
-
Multiple interfaces: EXT I/O, RS-232C, GP-IB, analog out. Good for automated systems and integration.
-
Compact and relatively lightweight: enables use in lab, production or mobile inspection setups.
Applications
-
Incoming / outgoing inspection for high-voltage battery packs in EV and PHEV manufacturing.
-
Quality control of battery storage (energy storage systems) and high-voltage module shipments.
-
Bus-bar / interconnect resistance checks in large pack assemblies.
-
R&D labs studying battery aging, uniformity, wire harness resistance, high-voltage insulation issues.
-
Safety testing in high-voltage battery module design, including spark risk reduction.
