Less Details

Battery packs for today’s EV market are typically manufactured by interconnecting several cells in series and/or parallel to achieve the required voltage and current values for different applications. The connections between the cells are made through wire bondings, busbars, flexible and rigid PCBs or other methods which utilize solder joints to make the electrical contact, and the quality of those connections, in terms of electrical resistance, is a key factor to allow the battery pack to work properly. This speech offers an overview of the bonding/welding scenario; in particular the issues created by bad solder joints, impact on manufacturing costs, design for testability suggestions and practical solutions to perform electrical test based on real Kelvin measurements, with a resolution in the range of µOhms, performed via physical contact of the electrical probes of automated mobile probe test systems.

In this session, you will learn more about:

  • What could happen to your battery pack in case of bonding failures: A real test case showing the risk of potential consequences
  • Cost of scrapping vs. cost of testing: How to calculate the ROI for your electrical tester based on real statistical data 
  • DFT tips to maximize the coverage of your welding/bonding electrical test
  • Flying probe test solutions suitable for all battery packs made with cylindrical, prismatic and pouch cells technologies
