Would be very interested to know the max regen rate. I'd further be curious about the energy needed to be absorbed in a fully loaded rig on a 6% grade at say, 60 MPH.
270 kW is 362 horsepower of regen. That's gotta be way more than enough to use regen alone on any reasonable grade and load.

Is that power rating continuous or like the peak 30 second or so power most EV sellers like to quote?
Pulling 80k lbs uphill takes a lot of energy.

That is probably an aerohead question, has too many math squiggles for me, but off the top of my head I would say the level of regen is inadequate for 80k# on the grapevine. Should be continuous, rather pointless for a three minute rating.

There are many locations around here were the small single axle truck is dock to stock barely touching surface streets 16 hours a day moving things around facilities and yards up and down the same half mile stretch of road.
These make a lot of sense in the case your buildings are stretched over a mile

I read it as on the average trip the truck recovers 20 - 30% of the battery capacity using regen - not that the peak regen is 20-30% of battery capacity or motor rating.

Yes, there are a lot of those trucks. I'd say we have 20 - 30 trucks in our industrial park that never leave the park. They just switch trailers all day every day.

This is exciting! How fast can they crank them out? We have a lot of diseasel trucks running around here on short routes, idling all the time, etc. Like Old Dominion... Short routes with lots of stops. Perfect for that, and the CCS rates aren't bad either!
Is this pretty much just California only right now?

At the launch event Freightliner said they had 700 orders. Unless something changes with incentives the industry expects an initial spike in orders then a dip followed by steady growth. That initial spike and dip is due to the expectation that large fleets will initially buy a group of trucks to test and then spend years testing them to determine the real cost / mile and percentage uptime.
I'm sure California makes up most of the orders but they are other states with electric truck programs and California, Oregon and Washington state are doing a combined program to build HD truck chargers every 50 miles along I-5

1% of their global fleet - 800 trucks is 9% of their US fleet.
Freightliner is Daimler Truck's North American brand. In the rest of the world they sell other electric trucks like the eActros.
The trucking industry is conservative - they will test for a complete life cycle before making large purchases.
