In the Abuse Testing & Engineering group, we push energy storage and power electronics to their limits and beyond using specialized equipment to apply electrical, mechanical, and thermal stresses. Our goal is to provide rapid feedback to inform designs early in development, by understanding how robust systems perform under abusive conditions. We accommodate external regulations but have a strong focus on internal requirements and test to failure. Every Tesla battery product comes through our lab, both vehicles and energy storage.
