Setting a new standard for battery leak testing

Charged EVs

A leaky cell housing, one common failure mode for Li-ion batteries, can allow ambient humidity to come in contact with the electrolyte, triggering an exothermic (heat-releasing) chemical reaction. It’s a year-long process, so when we were awarded this SAE white paper, we thought it was a pretty good accomplishment.
