It is thee most fire prone voltage out there! just takes a high resistance connection and heat starts to build up in the plastic and on it goes till it goes poof! in flames! been there don that on systems from my solar power system to my diesel truck to my 92 4*4 ( I had to do allot of repairs from PO hacks)
We are talking about in a LEAF, under the dash. Everything is fused and a loose connection with high resistance would require a fuse failure (and likely the main fuse as well) and would likely kill the tiny 12 volt LEAF battery long before that type of heat built up. Its not like the materials under there are HIGHLY flammable. Take a torch to most of that plastic, it has to get really hot to flame. Now maybe if the car is charging overnight and the inverter keeps the 12 volt powered up as a loose connection heated up, but that would require a power draw on the connection and what's powered up under the dash when the car is off???? Its not like the car was driving for hours before the fire was going so it would seem (if caused by a 12 volt source) it had to take awhile to develop that level of heat.
I can accept its POSSIBLE, but you have to admit its just extremely unlikely in a newish LEAF. I'm saying I for one would sure would like to know the cause rather than dismiss this as just "another" car fire.
I'm sorry but again your lack of experience is clear here, often a high resistance (NOT LOSE) will rarely trigger the fuse but more then capable of generating enough heat to build up to cause ignition temps to be reached.
Just because there is a fuse does not mean you are 100% safe! (Even your standard breaker is not all that sensitive in a house unless using an arc fualt, gfci breaker with good grounding!)
All so this heat can be very rapidly built up.
As to what is powered? Allot, any time you can turn any thing on via a button there is power flowing. The question is how and why it happened
the why most of all, so far all the connections in the leaf are very well don.
I live off 12V still, and fuses do not offer me good sleep, being super care full and thorough with every wire connection, and using very care fully sized high speed fuses with just enough of rating to meet the load, and checking it every couple days.
12v is a dangerous voltage, it is the standard but that is not for safety reasons. (It is a miracle there are less fires from allot of the wiring they use in RVs and quality of general public wiring skills)
As for the bottom statement, I do 100% agree, it is a rather unique failure and deff needs to be under stood!
2013 SV Leaf, Level 2 charger, so far all works great! 130Km daily, 100% charge at night on 240 then trickle charge for 8H durring the day on 120v.
Level 2 charge starts at 130am environmental starts at 6am to 25c for a toasty warm defrosted car!
