It isn’t exactly an efficient use of limited resources (battery cells) to put a 300 mile battery in something as large as a school bus that only drives short distances every day. That could be up around 300 kWh. What if it only drives 30 miles per day the vast majority of days? It’s only using 10% of the total pack capacity daily. Not saying buses shouldn’t be electric, just that maybe they should be plug in hybrids with smaller batteries and a gas range extender for long trips.
The efficiency could be improved if the battery served as grid storage while not in use, but still not optimal because it’s not permanently attached to the grid and may be on the road during peak hours.

Most rural buses are On the road for at least 4 hours a day. 45-1 hr trips to school are common.
And that assumes all ages in the same bus.
