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.

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
