Chevy’s Not Taking Any Probabilities With Bolt Battery Packs


Some current posts on Reddit give us some information that may look dangerous on the floor however actually present us one thing good. It seems that GM’s battery software program errs far on the facet of warning for Bolts and Bolt EUVs after the fireplace recall.

As you may see within the picture above, there’s a warning on the show of this 2023 Bolt EUV. Worse, the car was sitting when the entire thing began. “It was simply parked within the storage, not charging, and swiftly we hear the automobile alarm go off. We are able to’t get the automobile alarm to show off and once I went within the car, I noticed this message. GM is sending a tow truck…,” the unique poster stated.

Given the historical past of Bolt and Bolt EUV autos, this “battery hazard” message, accompanied by an alarm that may’t be turned off, sounds completely horrifying. In any case, since 2020, GM has been compelled to restore each single copy of the automobile, and with an entire battery pack alternative. There have been only a few precise battery fires, however they finally discovered that defects in LG Chem battery cells GM used have been so widespread that restore and monitoring for defects to indicate indicators of hassle wasn’t an possibility. So, all packs needed to be fully changed with new cells.

Even the most effective manufacturing traces nonetheless spit out a number of defects, although. The brand new Bolt battery packs haven’t had any widespread issues, nevertheless it’s not protected to imagine that the improved cells will all the time be excellent. So, it’s informative to be taught in regards to the first defective battery we all know of post-recall.

After getting towed to the vendor, service personnel disconnected the 12-volt battery. The native technician appeared on the battery and decided {that a} new pack was doubtless wanted, however then one thing extra uncommon occurred. A GM engineer got here out to the dealership and gave the pack a re-assessment, recommending a pack alternative.

As for the driving force, GM is taking excellent care of them as properly. Whereas the car is unavailable, GM set the driving force up with a rental automobile during the restore course of whereas additionally providing to pay for any gasoline wanted to maintain the rental driving. The gasoline must be bought and reimbursed, however that’s greater than many producers have completed for folks needing a restore prior to now. So, GM appears to get that EV drivers don’t like paying for gasoline!

Some Takeaways

Whereas we’d all like for EVs to be excellent, they’re like all automobiles on the street. Regardless of how a lot thought goes into them, defects that current some severe hazard to their house owners, their property, and the general public at massive generally get via. Hearth remembers are pretty widespread in ICE autos, and EVs are about 20 instances much less prone to catch hearth.

I don’t learn about you, however I’d actually assume that ICE automobile house owners (I personal each an EV and an ICE car) want to have a helpful dandy warning alarm come up if there was a hazard of fireside. However, the truth that burning is a standard a part of ICE operation and that flammable liquids and gases are regular makes it rather a lot harder to identify an issue earlier than it’s too late. Positive, regular upkeep can hold a strong ICE design from ever catching hearth, however defects that pop up don’t announce themselves to the ECU in an effort to get an opportunity to evacuate.

Like all car designs, this message that GM’s EVs can provide us when there’s hazard of fireside got here from expertise. Because the outdated saying goes, “Logic comes from expertise, which comes from dangerous judgment.” GM’s expertise with an costly and terrible hearth recall was not solely dangerous press, however value the corporate some severe money. So, you may guess that such an expertise is one thing they’re very dedicated to not repeating sooner or later.

As a part of that previous recall, the corporate first tried to keep away from changing all batteries by growing a battery monitoring program. Without having so as to add any new {hardware}, they discovered a means for the battery administration system and the car’s laptop to work collectively to look at for uncommon voltages and maybe different electrical readings (resistance, and many others.). If issues get too far outdoors of regular limits, the car units off an alarm and warns folks to keep away from it till somebody can test it out and ensure every little thing is OK or restore it if it’s not.

So, it’s fairly clear that GM autos are going to be rather a lot safer sooner or later, as will different EVs as these design methods get on the market. As a substitute of auto fires being a seemingly random and unavoidable catastrophe, EVs are capable of be extra resilient, and fail gracefully as an alternative of failing catastrophically. Not all points could be detected on this means, however we’re about to go from a world the place EVs have 20 instances fewer fires to at least one the place they’re much more uncommon.

For GM’s EVs, we’re additionally doubtless seeing some excellent news in {that a} GM engineer got here to the vendor to test issues out. This isn’t an remarkable factor to occur, however when it does, it’s virtually by no means for one thing routine or well-known. So, there aren’t a bunch of Bolts on the market tripping off a battery warning within the software program. It’s uncommon sufficient at this level, even after the alternative packs have been out for some time, that it’s price escalating to a better knowledgeable degree.

On the identical time, I might be unsuitable about all this. This alarm might be among the many first of a wider downside that will once more should be recalled like the primary one. Nevertheless, the rarity of the issue and the early warning system vastly reduces the probabilities that we’d see one thing as newsworthy as the primary recall. So, even when I’m fully unsuitable in my optimism right here, it’s nonetheless prone to be rather a lot much less painful for house owners.

I’ve reached out to GM to see if they’ve any additional details about this incident, and I’ll make sure to share what they inform me in one other article or in an replace right here.
