EV school bus

No those batteries will not likely last super long... Especially in areas of very high temperature or lower temperature aka low overnight temps less than 20°f .

Cadex website has all kinds of fun information about batteries. Well worth reading that information. Kinda interesting.
You must include climate and weather into your bus consideration. What works in Portland OR is not going to work in Phoenix AZ or Fairbank AK. Why would you use an EV bus in a diesel generator grid in the arctic circle? If diesel PM pollution is a concern you should use a gasoline hybrid with NiMh battery.
 
So 12 years life. The bus costs $350-$400 vs a 125k -150k for a non ev bus.

This article states $125k-175K repower cost That's at todays cost not what it will cost 8-12 years from now.

So will you re-power an 8 yr old bus and spend 125-175k or buy a new bus for 350k

It's still not cost effective.
Or, those batteries could be a lease with warranty. I'm sure some investors on Wall Street would love the idea of such investment like they did with a government bond.
 
In the video the manufacturer pointed out they used a lithium iron phosphate battery as less fire prone than lithium ion.
 
probably so, but as a taxpayer, i would not.
You already did. Look at your property tax bill and how many bond measures you were paying. I'm sure school bus, the diesel ones, is somewhere within those.

Cost per day per student is just a number, diesel or EV battery lease.

This is the issue, it comes down to cost, especially for many smaller municipalities. I think one day EV school busses will be a thing, but right now the cost to purchase the busses along with the infrastructure to support them is a cost these towns/cities can't justify. The University I work at generates most of its own power, and they still couldn't justify doing it for ~50 EV facilities trucks because of the cost associated with redoing the infrastructure.

Yes i'm paying, but i dont' want to pay 4-5 times the cost.

I'm not against EV, if its cost effective and makes sense. Some things it does, others not so much.
 
I drove a school bus(gas) , back when you kept a bus at home and was a student driver. My route was about 25miles

So

50miles a day@ 7mpg=7.14 gallons per day x 5 days=35.7 gallons per week.

36 gallons x 36 weeks of school =1296 gallons of gas x say $4.00 per gallon here= $5180 per year

$5180 x 5 years = $25,920

Much less than $100,000 battery replacement.

Plus the gas bus is good for 10-15 years with no engine replacement.

EV bus will probably need batteries every 5-7 years


I'm sure there are short or longer bus routes, and more expensive fuel in some places, and even year round school.

It might even be worth while to have an ev bus if they go to school year round.

Thomas Built has an 8 year 175K mile warranty on its EV batteries. I would expect many to last longer than that, especially if the charge range is limited. There’s always the possibility of premature failure where it’s an EV or ICE.
 
While I agree that an EV school bus does make sense, I am still struggling with the idea that most school buses are built on the same commercial duty chassis as many medium duty trucks. I feel like there could be a safer, more comfortable, and more efficient platform that could carry the same payload. I know that the vehicle referenced in the video was simply retrofitted, but I think a bespoke EV people carrier platform would benefit the industry greatly.
From what I remember from Mercedes Streeters articles on Jalopnik the black line is actually the seat height in case of an accident.
 
First off, there is no school bus mandate in California if I remember right. Most of the K12 students don't get to ride school bus and in my district, only those in "safety area" gets to ride in addition to the special need children. What is a safety area? If you have to cross railroad track or a highway / express way, not a 4 lane regular blvd with traffic light.

So "all new school bus EV by 2035" could means they just don't buy too many to begin with. I think my elementary school with 600 kids only have 2 short buses and my middle school of 1200 kids have 4 long buses and 2 short buses. Most have parents pickup and drop off (or private after school shuttles).

One thing about EV school buses is that they are used for short range (at least in urban schools), and they are parked most of the time, so they can be charged for 8 hours every 20 miles of range. Urban buses have a lot of stop and go and they don't need a lot of range, but they do need a lot of torque. If anything diesel hybrid is the best power train for buses (not CNG, Muni has to warn the politicians that CNG can't climb a lot of the hills in San Francisco so don't just go get a ballot for the sake of it).

EV school bus can probably charge off a regular EV charger and still works well.

School buses can be used in rural school districts where they need to cover a lot of area. However, I can’t imagine that the range of most electric school buses wouldn’t be adequate. If they need more range, it just needs a bigger battery, which isn’t that difficult to implement. I understand most bus batteries go in the roof and columns.

The best feature of any modern EV is the lack of a transmission and the ability to crawl up a grade if needed. My parents’ Tesla Model 3 is parked in a garage with an inclined driveway. I’ve taken it up the driveway at 1 MPH just to see if I could do it,

I do remember the diesel buses that I rode to/from school. They were normal transit buses (GM New Look and Gillig Phantom) but had difficult going up hills with enough passengers. A driver might suggest more passengers in the front to help.

There’s this hill near where I live, and over the years I’ve seen lots of various transit buses there. It’s steep and it’s not that busy, so it’s almost an ideal place to train bus drivers on how to handle steep hills.

It’s a very good point that school buses put relatively few miles on each year where as a commercial or transit bus puts a huge number of miles on. And as alluded in other posts, the buses are paid for from the strained budgets of the school boards. On the other hand, so far Tesla S batteries are now 8 years old and for the most part are still good, so the verdict is still out on that one. I’m thinking the economics won’t work with local school boards unless the Feds or State pay for with your other tax dollars or more likely just add it to the deficit . Five billion dollars in California’s case shown in posting #35. I’m sure the school boards could find a better use for the money. Apparently there are 25,000 school buses in California.

Look at this piece of fake news. The article is supposed to be about school buses but they quote cost savings of TRANSIT buses. There is absolutely no comparison on the miles driven on a transit bus vs a school bus.

Well the buses will go here, and the busses will go there, because that’s what busses do. I just love them, I love electric busses, I do. 😂

On a serious note, we grew up riding the worst possible contraptions to school. But they did have epic heat. That’s was a good thing as my house did not.

I don't see any reasons other than cost or fire to avoid an electric power train. Maybe the fire risk can be addressed by LiFePO4 batteries, or eventually, solid state cells.

Although electric drive certainly eliminates using the bus for longer field trips and activities like summertime travel.
 
12 years' warranty, not 12 years' life. Batteries don't fail the day after warranty, just like engines don't. The failure rate will be a small percentage of total, just like it is with an engine, with most going way beyond the end of warranty and likely on to a second, third or more life.
you say batteries.. but its thousands of cells.. lets so how that goes on a bus route in Arizona
or MN in the winter.
 
The latest number I’ve been able to find suggest a new diesel powered bus is just over $100,000 US dollars. An electric powered school bus is just under $300,000 US dollars. Anyone else have more accurate actual numbers?
