General Motors will start repairs on fire-prone Chevy Bolts one month from now

General Motors will start supplanting harmed and fire-prone battery cells on some of its recalled Chevrolet Bolt electric vehicles in mid-October, the automaker declared Monday.

General Motors (GM) first reported a recall of the Chevy Bolt electric vehicles in November 2020 because of fire hazard, yet it didn’t have an immediate fix. In May, it declared a software repair, however at that point there were two fires including Bolts that had gotten that fix, inciting one more recall in July of 70,000 vehicles. After a month, the automaker gave a recall on another 70,000 vehicles.

In declaring the latest reviews, GM prescribed individuals not charge the battery to over 90% of its ability. They additionally suggested that individuals not drain the battery to less than around 70 miles of range.

GM’s battery provider, LG, has carried out new manufacturing processes that will prevent the production of battery cells with the kind of imperfections that were making some catch fire, GM said. The Bolts’ high-voltage batteries have been faulted for something like 13 fires worldwide, as per GM.

A representative for LG didn’t promptly react to a request for comment on the matter.

Recently manufactured battery modules will start shipping to Chevrolet sellers in the middle of next month. Within 60 days, GM will start installing diagnostic software on Bolt vehicles that will consistently monitor the battery pack for indications of a risky imperfection.

In an electric vehicle, in the event that one battery cell has an imperfection that permits its stored energy to be released in an uncontrolled manner, that can make it heat up. That heat can, thus, harm different cells close by making them release their energy as heat, as well. This can begin a chain response known as “thermal runaway” that can prompt a fire. Still, electric vehicle fires are uncommon contrasted with fires in gasoline-powered vehicles.

In some Bolt battery cells a pair of unrelated manufacturing defects, on the off chance that they ended up happening together in a single cell, could permit that process to start a fire, as per GM.

Before there was a fix for the vehicles, GM was offering some Bolt EV proprietors buybacks. GM would not say the number of vehicles it has repurchased from clients. The organization said it is deciding if to repurchase individual vehicles on a “case-by-case” basis. On the other hand, GM was likewise presenting to exchange the vehicle for another GM vehicle.

As the new batteries become accessible, GM will start substituting the whole battery pack for the older vehicles associated with the first recall. For more up to date Chevrolet Bolt models, GM will discover and supplant just battery modules that are observed to be inadequate.

GM executives said Bolt proprietors could securely get back to normal use of their vehicles once the battery modules or battery packs have been supplanted depending on the situation, or when the diagnostic software considers the batteries to be free of defects.

GM executives couldn’t say when full production of the Chevrolet Bolt vehicles themselves may continue. The Bolt was most as of late accessible in two body styles, the Bolt EV, hatchback car, and the Bolt EUV, a marginally taller crossover SUV version.
