Good chance it will be a nickel saved for the public. Do you have comprehensive information otherwise?

More fear factor and FUD.

I would thing school buses would be a good fit. Charge overnight, then if needed, some charge in the daytime between runs. Maybe solar on the roof of bus to do a little daytime charge?

Could be if they have enough range in winter.

Easy, or at least to my thinking...

Known issue with any battery's performance in low temp operations.

Then manage to that

  • Increase battery capacity to account for their drop in performance
  • Heat the batteries
  • Instead of all of the suggestions on powering them along the ride...just have plug-in stations throughout their route
  • supplement it with on-board ICE's during the winter months

Failure seems a bit strong by what is written in the link.

Electric school buses are already on the market. With a 155 kwh battery they might offer enough range for typical school district usage. When I drove bus many years ago a typical bus would do about 7 or 8 runs a day, with a total distance of 80-100 miles per day. The claimed 120 mile range would work on a good day, but during cold, rainy weather power use would climb. There's a couple hours of down time during the day where buses could get a little "bump" to their batteries. A 200 kwh battery might give enough range to make the buses a little more practical. Upgrading the electrical systems at the bus barns would be a significant expense that school districts might be reluctant to invest in.

Yes, would need to upgrade power to barn. Of course one of my rants is parents that need to load kids in car, and set at the bus stop. Bet in my area it would average 3 cars idling all the time bus is running...

Edmonton is buying 50 electric buses. -30C winter temperatures are not unusual. Interesting.
