has passed another milestone on the way to Job 1 for their Roadster. The battery pack (or Energy Storage System as
likes to refer to it) has passed the UN and UL 1642 testing criteria. The tests evaluate several areas include shock and vibration, altitude simulation external shorts and temperature cycling to ensure that the pack is safe for both transportation and use. The batteries have been extensively tested on both an individual cell basis and as an integrated pack. Tesla is still on track to begin production in early October and customer deliveries a few weeks after that.
