E-Mobilty: Battery Connections with Ultrasonic Wire Bonding

Ultrasonic wire bonding is one of the most flexible and beneficial joining technique of batteries in the production of battery packs for e-mobilty applications.

  • Current-carrying contacts
  • Contacts for cell voltage monitoring
  • Cell to cell, cell to busbar, cell to PCB, and other electrical connections
  • Electrical connection to the battery management system (BMS)
  • Fully programmable and tolerance compensating production process

Wire Bonders offer maximum flexibility with working areas from 100 x 115 mm up to 700 x 1132 mm for the battery connections of small and large sized battery packs

Automation: Manual and fully automated operation

The precise and safe handling of the battery packs in and out of the production machine plays a significant role in controlling the product quality, yield and efficiency of the production equipment. For this reason Hesse GmbH is offering standard components as well as individually adapted automation concepts.
