That said, relying on a technology with a temperature requirement anywhere north of -10c was a foolhardy decision.
There was no temperature requirement when they were purchased. Now it seems likely that New Flyer will be sued.
From the article:
Clark also explained that the five electric buses were “operating well” until November 2025 when the batteries “were recalled for fire hazard.”
The recall prompted a software update from New Flyer to “decrease the likelihood for fire” that “included only allowing the bus to charge to 75% and to not allow charging when the battery is below 41 degrees,” Clark explained.
“Previously we could charge in any temperature to 100%,” Clark said.
Why do you think internal combustion engines have more than almost nothing at all to do with tire grip?
Throw air actuated chains on like every snowy municipality already does for their fire trucks and school busses and call it good. This solution is one every regional transit authority that deals in snow is already aware of and familiar with and it doesn't matter what your source of motive power is.
The drive is nearly identical to a regular diesel bus with an open differential, except it doesn't work in the winter.
