Until you know what the weight is that they are hauling, your you dont have a clue. Your missing the most important data!!

Interesting data. It's too bad that the companies are not giving real world data. I am retired but worked for Pepsi (Tulsa) Several trucks (OTR) did daily runs to the Dallas warehouse (250 miles). Their return trip were never empty. Deadheading is loss of revenue. Anyway, good reporting. Cost analysis would be nice info too. EV cost per mile vs ICE.

Great information 😊

I only see a brief moment of regen braking, right after summiting Donner Pass on the way up Actually, there's more on the way back. There's some significant regen braking just after topping Donner Summit on the return leg, including picking up almost 2% SOC starting at 9:55.

Charging to 100% is not that big a deal provided you don't leave them at 100% - I'd say they've sorted out their charging so it finishes charging just before it begins the next route.

Awesome 😎

Will be interesting to see how Tesla adapt to different markets. In some EU markets like Finland and Sweden some highways allows 34.5 m and 74 metric tons. While other use and in many cities, they have to be able to drive in narrow streets. Also, there are regulations how long a driver is allowed to drive, and charging can be done during resting period.
-
Lithium ION batteries are limited to 80% as Lithium metal precipitates on the electrodes at high charge levels. Lithium Iron Phosphate batteries are recommended to be charged to 100% at least weekly on the other hand. (Tesla manual data).

Seems like they are better than I thought they would be. I thought they would be fine especially for local deliveries. Once they get the megachargers in place it will be easy for them to go across the country. Not sure what the charge times are.

Being "maxed out" at 82K lbs still doesn't tell us how heavy the payload is. Without this, we're not learning anything. And a company that wont provide this most important of information in specking out a truck, they're hiding vital information. Go spec a transport truck. I don't think you're going to find a transport company that will purchase a truck that doesn't provide all the specs. No jumping to conclusions necessary if they aren't giving you all the specs. They're hiding something vital.
-
Having half the battery capacity of the Tesla means that the Freightliner and Volvo can take higher payload since the battery is lighter. So they are moving more freight using the same amount of energy.

need a part 2 on smaller trucks
-
I’ll be interested to see what the range and efficiency numbers look like after a year of being run like that. I think that will give a good indication of how well these trucks can compete with their diesel counterparts
-
The charging limits have nuances. It's not charging above 80% and depleting below 20% that is the problem. It's leaving the battery outside of that over time. So for regular driving you can use the whole range, just charge all the way and go and then charge above 20 when finished.
-
Actually a lot of trucking today runs up' against reliability issues and high maintenance costs
-
This does not seem to be a fair comparison. Tesla Semi is obviously using 2 drivers per day and charging 3 times per day. With 1 driver and charging twice, a realistic range could be 500 to 600 miles in fast traffic.
-
How about... calculate cost per mile driven, at a certain load?
-
How will they perform in harsh weather conditions knowing how the batteries perform in the cold especially
-
Is ironic that people are worried about the range when DOT driving limits are the bigger limiting factor.
-
I deliver Amazon, and they charge all those eVans to 100% every day.
