Tesla Semi units spotted testing on-road near Nevada production plant

Tesla Semi units spotted testing on-road near Nevada production plant-TESLARATI

Tesla Semi units were spotted testing on-road near Gigafactory Nevada as the automaker prepares to make its first deliveries in just over a month.

The Tesla Semi is one of the automaker’s most anticipated products, and after being delayed the past two years, the company is nearing the first deliveries of the vehicle to PepsiCo. on December 1. As a result of the imminent first deliveries, Tesla is continuing to test the Semi on roads near Gigafactory Nevada and the mysterious production facility the vehicle is built in.

Video of two Tesla Semi units traveling near Nevada SR-439 and Denmark Dr., just off of Electric Ave. where Gigafactory Nevada is located, was found by Teslarati on Snapchat last evening.



For reference, here is where the Semi units were spotted in relation to Gigafactory Nevada.

On-road testing is not out of the ordinary for any automaker ahead of an upcoming vehicle launch. We have covered Tesla and many other automakers testing vehicles on public roads in the past, and it is a good baseline to see how the vehicle will handle and operate in an everyday setting.

Tesla is planning to start deliveries of the Semi on December 1 after aiming to make deliveries of the vehicle in both 2020 and 2021. Supply chain bottlenecks and battery constraints prevented delivery in the past, and many skeptics may be wondering, “What is different this time?”

Yesterday, we reported that the Tesla Semi had officially received a Certificate of Conformity from the EPA, which it had never received previously. This ensures that the Semi has been assessed and tested by the EPA, and it was found to be compliant with federal emissions and fuel economy standards, something every vehicle in the stream of commerce must abide by before receiving the Certificate of Conformity.

Despite aiming for deliveries in 2020 and 2021, Tesla had never applied for or received a Certificate of Conformity for the Semi. This development alone is a tell-tale sign that Tesla is aiming to deliver the Semi very soon.

2023 Tesla Semi Gets Green Light From The EPA To Start Deliveries-INSIDEEVs

The EPA has granted the 2023 Tesla Semi a Certificate of Conformity, which allows for customer deliveries to begin.​

By: Dan Mihalascu


The Tesla Semi is slated to begin deliveries on December 1, Elon Musk announced earlier this month, with PepsiCo to become the first fleet customer to receive the electric truck.

Since his tweet announcing the start of production and deliveries, Musk offered more updates on the Tesla Semi last week during the Q3 2022 earnings call. The most notable were the production target of 50,000 units annually by 2024 and the 500-mile (800-kilometer) range when loaded with cargo.

Now, there's more good news for the EV maker, this time from the Environmental Protection Agency (EPA), which has given the Tesla Semi green light to begin deliveries. More specifically, the agency has assessed the Class 8 electric truck and granted it a Certificate of Conformity, which allows it to start sales.

This is a big deal because it marks the first time the Tesla Semi has received the EPA's Certificate of Conformity, despite the EV maker announcing imminent Semi deliveries in 2020 and 2021. Most importantly, it means that the Tesla Semi is finally good to go.

The EPA told Teslarati that the 2023 Tesla Semi has officially been granted a Certificate of Conformity on September 29, and that the Certificate is valid until December 31, 2023. The announcement comes shortly after the EPA has granted Certificates of Conformity for various 2023 model year Model S, Model X and Model 3 trim levels.

A Certificate of Conformity is issued by the EPA when a vehicle is confirmed to adhere to the agency's emissions and fuel economy requirements. According to the EPA, "every class of heavy-duty engines/vehicles and non-road engines introduced into commerce in the US must have a Certificate of Conformity, and they are valid for only one model year of production."


Tesla did not previously apply for the Semi to be approved for a Certificate of Conformity based on the EPA's list of approved heavy-duty vehicles. The list is updated quarterly, and the Semi has never appeared on it. The EPA confirmed to Teslarati that the Semi would be added to the list of conforming heavy-duty vehicles in January 2023.

This is a clear sign that Tesla can officially use the Semi on public roads and deliver it to clients. PepsiCo will become the first customer to get the Tesla Semi at its facilities in Modesto and Sacramento, California.

These 2 units are registered to Tesla And are used in transportation activities, they Have been “testing” these two for many months all over Nevada and California hauling supply chain goods as well as cars from time to time, the second truck was at Giga Texas several weeks ago.
 
What size batteries do these have and what is the charging paradigm for them? Semis are necessarily much more inefficient than cars so that means they will need more time to charge. A semi tractor’s fuel tanks are generally 250-300 gallons. It already takes 20-30 min to fill up with diesel. If it takes 6 hours to charge it’s hard to see how the Tesla Semi will ever become practical.

Tesla claims 70%, 350 miles, in 30 minutes.

Ah yes, I stand corrected.
That was actually the other, unspoken half of my question. Having a huge battery and a huge range isn’t terribly helpful if it takes a week to charge. Nominally a 1MWh battery would take 40 minutes to fully charge at a 1.5MW charging station. That assumes 0-100%, linear charging at the full capacity, etc so it will likely be longer but it gives us an idea.

I wonder what kind of voltages they’re going to be using - 1.5MW is a huge a mount of power. Our house has 200A service and a 1.5MW charger would take 44 times that!!! And 2000 amps? Yikes! You’d need a forklift to lift the connector! It also appears Tesla has necessarily upped the charging voltage to allow greater power transfer.

The MCS standard supports 1,250 volt and 3,000 amps. And, no you don't need a forklift to lift the connector. In fact, I don't think the connector is much bigger than a CCS Type 1 connector.

Here is a couple picture of one:

ok - we all know the CCS connecter is oversized and cumbersome, but this just puts it to shame!

1.25kV * 3,000 A = 3.75 MW. Dang!

I did some quick calculations:
  • Diesel Fuel is about 0.83 kg/l with an energy density of 43 MJ/kg. There are about 0.2778 Wh/kJ
  • 43,000 kJ/kg * 0.83 kg/l * 0.2778 Wh/kJ * 3.785 l/gal = 37.527 kWh/gal
  • A big rig can hold up to 300 gallons of fuel meaning 11.258 MWh of energy. That's a crap-ton of energy!
  • Fully loaded they get about 6 miles per gallon (this is highly variable, of course), that gives 37.527/6 = 6.25 kWh/mile.
Of course, ICE engines are horribly inefficient so a lot of that energy is just wasted heat but it gives a rough idea. It also gives a very good example of how efficient pumping gas or diesel is as a means of transferring energy.
