Like most American faculty youngsters, I’ve enduring reminiscences of touring in large yellow faculty buses and inhaling large diesel fumes.
Companies like Lion Electric wish to change the diesel faculty bus expertise by providing a trio of electrical faculty buses that can remodel and make greener (not yellower) the varsity commute for college students throughout the nation.
Electric faculty buses are perfect for giant industrial adoption, they’re the biggest type of public transportation, with 480,000 in service on faculty days. They typically don’t drive very lengthy routes; they cease and begin often; and so they have extensive predictable durations of down time.
This would permit a faculty to make use of one even with out the set up of upper voltage quick chargers on web site. Level 2 charging can be sufficient to get the buses charged up in a single day and even as they idle in the course of the faculty day and it’s less expensive/simpler to put in than a DC fast charging station.
The EPA has additionally focused faculty buses as a approach to scale back air pollution broadly, and the company just lately introduced particulars to its $5 billion electrical faculty bus program, together with an preliminary installment of $500 million as part of the most recent infrastructure invoice. The program features a lottery to obtain funding and prioritizes purposes to interchange internal-combustion buses in high-need, rural, and Tribal areas. And the rebate program doesn’t solely apply to the autos, it applies to the set up of wanted charging {hardware} as effectively.
Lion 6 Electric Truck
To get a way of what these electrical faculty buses might be like, I traveled to the Auto Club Speedway in Fontana, Calif., to get a while behind the wheel of the Lion 6 industrial truck that shares a Class 7 chassis with the Lion A and C faculty buses (the buses weren’t accessible for us to check at this occasion). There’s an enormous distinction within the heights of the autos, however from a driving standpoint the 2 must be fairly related with the identical energy output.
We sadly didn’t get to take the truck on the NASCAR-ready oval observe, however the infield course had been repurposed for take a look at drives of the Lion 6 and a number of other different commercially accessible electrical vehicles.
Lion affords a number of battery and vary configurations for the Lion 6 and the varsity bus as effectively. The model I examined got here with the biggest battery setup. Three battery packs have been mounted across the body (two within the center, one within the rear) for a complete of 252 kwh and 200 miles of estimated vary. On the varsity buses, vary will drop all the way down to an estimated 155 miles. The packs are composed of a pair of 42.2-kwh BMW i3 battery packs stacked prime of each other, to allow them to be cooled concurrently. Power figures examine in at 335 hp and 1,800 lb-ft of torque, at most.
The very first thing you discover when driving these giant autos with electrical drivetrains is how simple all of it appears. Hop into the seat, push a button to place the car into drive, launch the airbrake, and roll away. Thanks to all of that prompt torque from the electrical motors, acceleration is surprisingly linear and it makes these autos really feel smaller than they really are (I felt the identical sensation testing Thomas’ Jouley electrical bus final yr). If not for the outsized steering wheel, it might really feel very like driving an enormous SUV or an HD truck.
As good as a diesel engine may be at low-rpm torque technology, it isn’t in the identical class as an electrical motor that requires no spinning up. Driving a truck with out the diesel hum takes some getting used to. It’s eerily quiet within the Lion 6’s cabin minus the sounds of the air suspension bounding on the observe’s uneven floor.
The Lion 6 doesn’t provide completely different regen ranges. It retains it easy with what I’d describe as a medium quantity of regen that’s very noticeable in case you carry off all of a sudden however nonetheless requires the brakes to gradual the truck to an entire cease. Lion representatives stated this was to offer truck and bus operators much less complexity as they adapt to electrical autos, and to stop drivers from turning off the regen for preliminary ease-of-use that will undermine a number of the effectivity that these autos try to ship.
Lion C Electric School Bus
Lion lists charging occasions as 11 hours on a Level 2 charger, which drops all the way down to round 4 hours on a 50-kw DC-fast charger. That’s loads of time to get a faculty bus charged up in a single day. Lion additionally says one other benefit of an electrical faculty bus is that it may be cooled or heated whereas plugged in and idle, in preparation for a route. On a diesel bus, the engine would must be working for that to happen and that contributes to the quantity of emissions a faculty bus produces over its lifetime.
Lion Electric’s three faculty buses make up a big share of the corporate’s future gross sales. Of the two,422 autos in its present order e-book, almost 90% of that (2,136 autos) are electrical faculty buses. And the corporate has detailed plans to open up a big plant to construct electrical buses and HD industrial vehicles in Joliet, Illinois, by the tip of the yr. The plant may have a capability of 20,000 autos, and Lion says it’ll scale up manufacturing to match orders and demand. The firm’s present plant in Canada solely has the capability to supply 2,500 autos, so this can be a gigantic improve in its skill to supply these autos.
In addition to the Illinois plant, Lion additionally plans to open up a battery manufacturing facility of its personal in Quebec later this yr and batteries from that facility will start to point out up in Lion autos by the tip of the yr. That manufacturing facility may have an eventual 5 gigawatt-hours of manufacturing capability yearly, or sufficient batteries for 14,000 industrial autos per yr. It additionally offers the corporate higher management over the shape issue and measurement of its batteries to higher combine them into the assorted chassis that Lion affords.
It’s encouraging to see authorities funding and personal sector manufacturing ramp up in lockstep to handle environmental and emissions issues. School children will nonetheless get to make their very own yellow faculty bus reminiscences, however this time they received’t be so pungent.
