Customized Testing for Specific Safety Concerns
Standard test are not intended to encompass all reasonably foreseeable use and abuse conditions or failure modes. Exponent designs and conducts customized tests on cells and battery packs that can address specific safety concerns or special customer needs examples of such testing include:
- FAA Style Fire Box /Halon Suppression tests
- Thermal Runaway Characterization as Function of State-Of-charge
- Battery pack torsion and bending tests
- Battery pack deformation and penetration test
- “Super drop” test to assess result of severe mechanical impact
- Liquid intrusion test
- Cell-in-pack programming test
- Protection circuit board fault replication
- Partial stack short testing
