Summary

  • Customer Need / Challenge

    As electric vehicles push advancements in efficiency gains, structural battery packaging is at the forefront for optimization. This drives the need to validate structural battery pack design, both in terms of life expectancy against design targets as well as crash test compliance and survivability.  

  • Interface Solution

    Interface’s solution includes 1100 Ultra-Precision LowProfile Load Cells in-line with hydraulic or electromechanical actuators in customer’s test stand. Also utilized are 6AXX 6-Axis Load Cells to capture reactive forces transmitting through pack structure. Multi-axis measurement brings greater system level insight and improved product success.

  • Results

    The tests performed using Interface’s force measurement products validated the battery packs strong structural design.

Materials


  • (12) 1100 Ultra-Precision LowProfile® Load Cells
  • Four 6AXX 6-Axis Load Cells
  • Customer’s data acquisition system
  • Customer’s EV battery pack
  • Customer test stand with controller and actuators 

How it Works


  1. Interface’s 1100 Ultra-Precision LowProfile® Load Cells and 6AXX 6-Axis Load Cells are all installed throughout the test stand for the EV battery pack. The 1100’s will measure the force of the actuators performing the tests, and the 6AXX 6-Axis Load Cells will measure tension and compression. 
  2. The difference force tests are performed and force data results are captured by the customer’s data acquisition system.
