The Type-D school bus uses a 387 kWh lithium iron phosphate battery.
Ideally, rezoning and infrastructure changes would reduce the need for school buses. We don't have the time though, so this is a win. Hopefully production can ramp up and governments can create incentives for schools to buy these instead of dead dino powered buses.
School busses are one of the perfect fits for electric engines:
Set schedule with down time to charge
Specific route with known distances. Heavy and must drive up hills: which benefit from amazing torque generated by Electric engines. Large internal space for battery storage
Just pray Muskrat doesn’t somehow win the bid. We’ll never see them
Elon would do something ridiculous like buy Lyft for 10 billion too much and require drivers to use Teslas. He would then get a cost+percentage transportation contract. He then gold plates the interior components after a few years so the cost is higher, therefore the percentage is bigger.
And as long as it can cover the longest route on one charge it wouldn't need to cover that same distance every trip. You could pick the buses route based on battery % and have them alternate.
To expand on that, couldn't you also have a separate power source to warm up the bus before it was taken out on a cold morning? Something like an engine block heater for an ICE vehicle.
7% at the end of a ~300mi roundtrip rural run is really cutting it close 😳 although if the journey is mostly flat I think it's OK, as long as there's enough range to go via any diversion if the road is blocked.
They could definitely get a bigger battery onto that roof, the main expense there probably would be customising the aircon to fit around a roof battery pack instead of buying one off the shelf
The electric buses here all have roof mounted batteries and they last pretty long - the chinese Yutongs are out all day with the heating on, but our domestic built ones seem to last only 3/4 of the day, and after that they vanish with the old diesel ones appearing on routes until the night
Keep long routes diesel or gas for now and wait for battery tech to improve. Even if 70% of buses are moved to electric, it is still a big chunk of emissions that are cut.
You can offset some loss by putting solar panels on the roof. However you have to balance it properly because people forget that these things weigh 45lbs each and you need to factor the additional weight into equation.
Most districts set it up to have a few buses do all the HS students, then the MS/Elementary students then kill a bit of time and repeat. Without much time to charge 4 routes on one bus might be close.
Not sure about cooling, but there are a number of heating options that exist. We're basically looking at an RV, perhaps they could have some kind of diesel heater as a stop gap. I would think that could easily be retrofitted with something electric or ??? down the road. Mini wood stove haha. Maybe not kid friendly.
