There are already several threads discussing this.
The MSD is outside the steel battery box, sticking up into the passenger compartment through a hole in the steel floor. It is directly under a foam, and fabric seat bottom. If the fires were caused by sparks coming from the MSD, they would start the seat bottom on fire. In the Bolts which were not completely consumed by fire, the rear seat bottoms are somewhat melted, but not burned up. In those cars, the steel floor, and steel battery box were burned pretty badly, and the fire crews chopped them open to expose destroyed BMS, and wiring.It is not stuff getting into the MSD, or the BCM, it is sparks getting out that concern me.
It does not. They are not pulling power from high cells to top up low cells. Nobody is doing that in a car, as far as I know, so they would just be burning off the high cells through the balancing resistors for no benefit. If a BMS were to fail on, it could turn into a toaster oven.Does anyone know if the Bolt does cell balancing when the car is just parked and not plugged in? I think 2 of the 3 cases were that scenario: recently parked but not charging.
Is this an open FB page, or one you have to join to see? Can you post the story here?Today I saw one more on the FB group. Not sure if the conditions are the same.
As the link is asking for a FB login I pasted the screen capture of the post.
Given the palm trees, I am going to guess either California, or Florida.There is no reference to where it happen either.
It is definitely the same one. Looking at his videos, I determined he lives in Jacksonville, Florida.Looks like the same one from the facebook group linked to earlier in this thread.
The BMS is inside the battery box, totally sealed off, even from ants, let alone rodents.Could it be possible that rodents are getting into the area with the BMS and chewing on wires? How "sealed off" is this area?
