Vermont EV Buses Prove Unreliable For Transportation This Winter (vermontdailychronicle.com) 141
Electric buses are proving unreliable this winter for Vermont's Green Mountain Transit, as it needs to be over 41 degrees for the buses to charge, but due to a battery recall the buses are a fire hazard and can't be charged in a garage.
Spokesman for energy workers advocacy group Power the Future Larry Behrens told the Center Square: "Taxpayers were sold an $8 million 'solution' that can't operate in cold weather when the home for these buses is in New England."
"We're beyond the point where this looks like incompetence and starts to smell like fraud," Behrens said.
"When government rushes money out the door to satisfy green mandates, basic questions about performance, safety, and value for taxpayers are always pushed aside," Behrens said. "Americans deserve to know who approved this purchase and why the red flags were ignored."
General manager at Green Mountain Transit (GMT) Clayton Clark told The Center Square that "the federal government provides public transit agencies with new buses through a competitive grant application process, and success is not a given."

Clearly the batteries delivered are somehow different and the ones delivered to Vermont weren't appropriate. This shouldn't be a question of the officials though. The basic function of a bus is to drive around the place and if it's sold in Vermont that means driving around the place in the cold. A bus that fails that is not of "merchantable quality" (look up the Uniform Commercial Code) and so the company that made them should have to fix them and until they do they have a duty pay for replacements.

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.
“Since the barrier to charging under 41 degrees is simply a software update, the manufacturer could find a technical solution that could resolve the problem this week,” Clark said. “We are seeking a financial remedy from New Flyer that could lead to litigation if not resolved.”
“New Flyer has indicated that replacement batteries will be installed within 18-24 months,” Clark said.
The actual problem: The buses need replacement batteries as the current ones pose a fire risk. To allow the buses to operate with existing batteries, software restrictions were installed to not allow the buses to charge under 41F. The software could be changed or the buses could get their replacement batteries sooner. The summary makes it seems like there are zero solutions to the issue.

"Way more" is carrying a lot of effort and cities can and should build exactly that type of infrastructure. If EV busses are anything like EV cars the cost upsides are in the long term and considering most busses run everyday the TCO over their probably 2 decade lifetime should be quite high instead of burning diesel all day long.
Even more so for busses than cars it makes pretty obvious sense since they already have dedicated depots they return to end of shift and they also spent quite a lot of time idling

I have been saying that cities should put more money into public transit for years and years. No one listened to me either.

Buses are used by "the poors". Nobody on either side of the aisle considers this an issue worth changing their vote over. The only reason we're even hearing about it is because the libertarian and right-wing media loves to get their base stroking their egos over the massive ICE pickup trucks they have parked in their driveways.
Of course, if your point was that America is uniquely bad at public transportation - that's true, but it's because the auto industry owns all the politicians.

So enough money needs to be put into it so that it is a comfortable experience. But people complain about high taxes as it is. And you can't out price the poorest of the poor.

Why do you say the left is losing when it's a RWNJ wannabe paper calling to get rid of the electric buses?

If you read the article, actually it is 'software that turns off charging when below 41 degrees and cold that don't mix well'. But don't let facts interfere with your rant.
