Battery module process

The battery module is a complete battery system unit composed of multiple battery units (battery cells). It is an important component in battery energy storage systems, hybrid electric vehicles (HEVs), pure electric vehicles (EVs), and renewable energy systems such as solar and wind. Battery modules are designed to improve the overall performance, capacity, and stability of the battery while simplifying the management and connectivity of the entire battery system.

process

Step 01

Battery Cell Loading: Placing cells on the production line.

Step 02

Battery Cell Scanning: The battery cell is scanned to confirm its information.

Step 03

Battery Cell OCV/ACIR Testing (OCV/ACIR testing) : Performs an open-circuit voltage /AC internal resistance test on a battery cell.

Step 04
