Electrovaya Inc. announced that it completed and passed fire propagation testing on two of its high voltage battery systems, each with over 50kWh in capacity. The testing was done in accordance with the UL2580 standard and one test was completed at an independent lab and the second completed in-house. This testing involved forcing a single cell in the battery system to thermal runaway through directly heating a cell.

The passing result was the fire remained contained and did not spread within or outside of the battery system. A real world comparison would be if there was a fire within the battery system at a single cell level, but did not propagate and lead to a further fire. From the Company's understanding, in most cases, this type of scenario with competing battery suppliers would lead to large and well documented battery fires.
