Cell & Pack Manufacturing

Cell & Pack Manufacturing

Challenges

surface cleaning; heat management

Manufacturing Process Map | Pack Assembly

Manufacturing Process Map | Pack Assembly

Connecting Battery Cells Battery cells are connected after surface is cleaned

Modularization The cells are attached to the module case

Challenges

avoidance of module short circuit and damages

Pack Assembly The modules are put in the battery pack and connected

Applying BMS A Battery Management System is applied to battery pack

Challenges

battery pack integration with other components in EV or BESS. Extreme climate conditions and use cases during the battery life cycle

Challenges

ensuring cable flexibility, Battery cells handling

Final Integration The battery packs are then used in Electrical Vehicle (EV) and Battery Energy Storage System (BESS)

Final Test A series of electrical test including charge and discharge cycle are performed to ensure the highest quality

Challenges

correct wiring and integration of the BMS

Challenges

testing sequence, results and accepted limits vary between manufacturers, resulting in lack of standardization
