AKE technologies represents the system partner for its customers in the field of assembly of electrical components. This is particularly advantageous in the production of battery systems because we take our customers by the hand when it comes to the relatively new technology and support it right from the beginning.

General Information

• Combination of automatic and, if necessary, manual processing stations
• Flexible design thanks to intelligent processing modules
• Connection of the individual processing modules with innovative transport systems
• Integration of hall logistics systems
• Flexible design thanks to set-up carts and exchangeable processing modules
• Extension and reduction of the number of modules in the event of changes in the number of units
• Complete data documentation and process monitoring

Processes

1. Automatic feeding and start of line tests of single cells and cell modules in different variants

• Round cells
• Prismatic cells
• Pouch cells
• Modules with prismatic or pouch cells

2. Cleaning of the battery cells

3. Assembling of the cells with monitoring of mounting force and distance

4. Application of adhesives and gap fillers:

• Process control with camera and 3D scanning systems
• Pretreatment of the application areas: plasma, flame treatment, laser, ...)

5. Laser welding of contacts with process monitoring

6. Scope of assembly in the HV state of the battery:

• Manual activities with high voltage protection of the worker
• Automatic assembly in special HV cells, worker access is only possible after the HV assembly has been completed

7. Leakage test of the fully assembled system:

• Air
• Helium
• If necessary subsequent filling of the battery with a cooling medium

8. End of Line testing:

• Communication test
• Plausibility test
• High Voltage test
• Functional test
