Here's the story:
The automaker has found five confirmed incidents of battery fires on the Bolt when the batteries were either at full-charge or almost fully charged
They suggest using Hilltop Reserve and only charge to 90%. There's no way I would perform a recall that limits my charge to 90%, especially when I can do that myself without wasting my time at the stealership.The recall, which covers more than 50,900 Bolts in the U.S., will require dealerships to reflash the vehicles' battery software to limit the maximum state of charge to 90%, Ortega said: "We believe this action will reduce the risk of battery fire while we work to identify the issue, and determine the appropriate final repair. We expect this software update to be available beginning Nov. 17."
Reminds me of how VW "fixed" the dieselgate vehicles by a software update that made them much less fuel efficient and quicker to burn out the DPF.What's my compensation for reducing my 60 KWH battery to 54?
That's what I was thinking. Also, since most of the fires happened in the last 6-9 months, that might suggest the same scenario: cells getting out of spec over time and having a hard time when carged to full. I think I'll wait until GM has a "real" solution; I only charge to 80% anyway. My guess is they'll reprogram the BMS, maybe so that it lowers the charge rate even more between 90 and 100%.Those that run Torque and monitor pack health probably aren't at risk of fire. I'll bet the problem only exhibits for unhealthy battery packs or cells. The reason why fires aren't more common is likely because it takes 2 or more things to go wrong at the same time.
I was initially thinking the same thing, but I bet there is at least 2 failures that must occur for there to be a fire danger. It could be that BMS reprogramming can eliminate one of those failures, making the battery safe. I do think at minimum, closer monitoring of battery health will result in increased cell/pack replacement.One would think that the liability of fire danger would also warrant a full rebuild of the pack but I can't imagine the cost to LG/GM.
It really depends. Many owners never come close to using the full 100% range in a day, and even though I drive 150+ miles a day, I still leave it in Hilltop Reserve most of the time.Ya, if the numbers on gmauthority are right (Chevrolet Bolt EV Sales Numbers) then 68,000 recalls is more than the total of 2017-2019 sold in Canada and the US so I think
Truth_in_adv is correct about the 66kwh packs being the only unaffected batteries. I have a hard time seeing GM convincing everyone to only use 90% of their vehicle, though. One would think that the liability of fire danger would also warrant a full rebuild of the pack but I can't imagine the cost to LG/GM.
