For the Tesla novices, a model S/X battery module is a brick unit composed of over 400+ cells. There are plenty of teardown videos showing that every battery pack is made from 12 to 16 of these modules.GRA wrote:https://www.autoblog.com/2019/06/28/tes ... -shanghai/GRA wrote:

And that's all for me today.. . . The company said in a statement posted on its Weibo social media account that a joint investigation team had analyzed the battery, software, manufacturing data and vehicle history.
Initial results show that this fire, which was captured on video, was caused by a single battery module fault located at the front of the vehicle, Tesla said.
The company has revised the charge and thermal management settings on Model S and Model X vehicles via an over-the-air (OTA) software update, to help further protect the battery and improve battery longevity, the statement said.
Having a module fail doesn't tell us anything about whether having the cell protection circuitries would've done anything to help. Much like how the iPhones, Samsung Galaxy phones, and the Boeing 787's all had cell overcharge/discharge circuits in place, yet didn't prevent them from going into thermal runaway.
