Measuring battery performance and safety using internal resistance (AC-IR) and open-circuit voltage (OCV)

Inspect the quality of completed cells, modules, and packs on production lines. Measure internal resistance (AC-IR) and open-circuit voltage (OCV) to check battery quality. Cells produced at the cell production factory are shipped to the module production factory after undergoing a shipping inspection. Since factors such as vibrations during shipment and even the passage of time can cause defects, batteries undergo an acceptance inspection before being assembled into modules and packs.

Reducing test system development cost and management man-hours

The new BT356xA has dramatically improved tolerances for line resistance compared to previous models. This improvement makes it easy to build test systems with large numbers of channels using relays. Additionally, a longer maintenance cycle for systems in use means fewer maintenance man-hours. Finally, its capability to handle thinner cables than with previous models* makes it easier to route cables.
*AWG 29 (0.064 mm2) wire equivalent to 2.2 Ω over
an 8 m round trip can be used with the 3 mΩ or 30 mΩ range.

Improve Productivity by Increasing the Number of Inspection Channels

You can use the Switch Mainframe SW1001/SW1002 to increase the number of measurement channels. Additionally, you can perform scan measurement by controlling two instruments at once, for example a BT356xA series instrument and a DM7276, or a BT4560 and a DM7276.

Preventing instrument malfunctions caused by static electricity

Batteries can become charged on production lines, for example, when being transported on a conveyor belt. When probes are placed in contact with such batteries, the resulting application of static electricity can then damage the instrument. The BT356xA series is designed to withstand contact with ±30 kV of static electricity*, preventing static-caused malfunctions and reducing testing line downtime.
* ±30 kV IEC 61000-4-2 contact discharge

LAN interface as standard

The BT356xA series is equipped with a LAN interface as standard equipment, making it easy for the instrument to interoperate with a PLC*-based control system. The ability to use readily accessible LAN cables helps lower costs during system development and maintenance. Furthermore, a design with strong noise and static electricity resistance helps avoid system problems.
*Programmable Logic Controller, a device that automatically controls one or more machines

The De Facto Standard of Battery Testers

The HIOKI BT356xA series
These highly advanced battery testers are best suited for shipping and acceptance inspections of cells and battery packs. They simultaneously measure internal resistance and the battery’s open-circuit voltage (OCV).

Since the AC-IR measurement method is used, the measurement time is shortened. In addition, highly repeatable results are attained with this method. These testers have a highly accurate 3 mΩ range, allowing for a resistance measurement of battery tab welding and bus bars. All of this combines for the best choice in battery testers.

High input voltage applications The input high voltage (1,000 V) model, BT3564, can measure the total resistance of the battery whole pack at once.
