Like most American college kids, I’ve enduring reminiscences of touring in large yellow college buses and inhaling large diesel fumes.
Companies like Lion Electric need to change the diesel college bus expertise by providing a trio of electrical college buses that can rework and make greener (not yellower) the college commute for college kids throughout the nation.
Electric college buses are perfect for massive business adoption, they’re the biggest type of public transportation with 480,000 in service on college days. They typically don’t drive very lengthy routes, they cease and begin incessantly, they usually have extensive predictable intervals 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 could be sufficient to get the buses charged up in a single day and even as they idle throughout the college day and it’s less expensive/simpler to put in than a DC fast charging station.
The EPA has additionally focused college buses as a solution to scale back air pollution broadly and the company lately introduced particulars to its $5 billion electrical college bus program, together with an preliminary installment of $500 million as part of the newest infrastructure invoice. The program features a lottery to obtain funding and prioritizes functions to exchange internal-combustion buses in high-need, rural, and Tribal areas. And the rebate program doesn’t solely apply to the automobiles, it applies to the set up of wanted charging {hardware} as effectively.
Lion 6 Electric Truck
To get a way of what these electrical college buses shall be like, I traveled to the Auto Club Speedway in Fontana, Calif., to get a while behind the wheel of the Lion 6 business truck that shares a class-7 chassis with the Lion A and C college buses (the buses weren’t obtainable for us to check at this occasion). There’s an enormous distinction within the heights of the automobiles, however from a driving standpoint the 2 ought to be fairly comparable 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 check drives of the Lion6 and several other different commercially obtainable electrical vehicles.
Lion gives a number of battery and vary configurations for the Lion 6 and the college 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 college 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 verify in at 335 hp and 1,800 lb-ft of torque, at most.
The very first thing you discover when driving these massive automobiles 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 on the spot torque from the electrical motors, acceleration is surprisingly linear and it makes these automobiles 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 will really feel very similar to driving an enormous SUV or an HD truck.
As good as a diesel engine could 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 Lion6 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 if you happen to carry off immediately however nonetheless requires the brakes to gradual the truck to a whole cease. Lion representatives mentioned this was to offer truck and bus operators much less complexity as they adapt to electrical automobiles, and to forestall drivers from turning off the regen for preliminary ease-of-use that might undermine a few of the effectivity that these automobiles try to ship.
Lion C Electric School Bus
Lion lists charging instances 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 college 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 have to 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 college buses make up a big share of the corporate’s future gross sales. Of the two,422 automobiles in its present order e book, almost 90 % of that (2,136 automobiles) are electrical college buses. And the corporate has detailed plans to open up a big plant to construct electrical buses and HD business vehicles in Joliet, Illinois, by the top of the yr. The plant can have a capability of 20,000 automobiles, and Lion says it can scale up manufacturing to match orders and demand. The firm’s present plant in Canada solely has the capability to supply 2,500 automobiles, so this can be a gigantic improve in its potential to supply these automobiles.
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 automobiles by the top of the yr. That manufacturing facility can have an eventual 5 gigawatt-hours of manufacturing capability yearly, or sufficient batteries for 14,000 business automobiles per yr. It additionally offers the corporate higher management over the shape issue and measurement of its batteries to raised combine them into the assorted chassis that Lion gives.
It’s encouraging to see authorities funding and personal sector manufacturing ramp up in lockstep to handle environmental and emissions issues. School youngsters will nonetheless get to make their very own yellow college bus reminiscences, however this time they received’t be so smelly.
