Supercharger - Oxnard, CA (EXPANDED Jun 2018, now 20 total)

[GabrielB]

Gene, thanks for the updates and the photos from a few days ago. You mentioned that construction of the 24 Hour Fitness and the staging for the construction is blocking the presumed trenching path. On your next visit to the site could you please get a photo taken from the area of the unfinished Tesla Distribution pad, and towards the utility power source? Progress in that "view" may now be the bottleneck we keep tabs on.
Thanks again for your on the spot reporting!

Gabriel, look at the photos. #1 you see pad and enclosure for the utilities transformer. #2 You look way down along the fence, a good 200 feet. It is at the end of this fence that the trenching will turn left at 90 degrees. #3 I am standing with my back to the fence taking the picture in the direction the trenching will head. #4. You see the pavement marking showing where the trenching will go under the fence and all the way to the back end of the 24 Hour Fitness now being built. #5. Picture taken over the fence where the trenching will likely head.

Of course, I could be completely wrong about all this!

Gene, That was fabulous. Yes, they really do have a long way to go. This may hold the record for the longest trench. The wooden enclosure in Photo #1 I think would hold the tall dark grey Square-D Distribution Panels that will feed the five Tesla Superchargers, and smack in the middle of Photo #5 looks like the dark green Utility Distribution Transformer.
The staging area inside the 24Hour Fitness fencing looks pretty empty, I don't see why they could not get permission to pass and trench. We'll see I guess....

Visited this construction site Friday 18th on way to TMC Connect. Slabs here have been poured, but not sure about slab in next next photo.

The two finished wooden enclosures with pads will hold the Superchargers that feed the ten charger monuments. The conduits are all in place and cement poured. The incomplete one is waiting for the trenching and conduit that comes from the Utility Power Distribution Transformer near 24hour Fitness. Can't pour the cement for that one yet.

I wonder what Gage wire is required to feed the 10-superchargers along that long distance?

See http://www.evpowers.com/wp-content/uploads/2013/09/EV-Powers-Hybrid-Battery-Service-and-Repair-Tesla-Supercharger-Plans.pdf for the plans for Madison, WI. There Tesla called out 250 mcm wire (slightly larger than 4/0). 250 mcm copper wire has a resistance of 0.042 milliOhm per foot. Because that is out and back, it's a total of 0.083 milliOhm per foot round trip. The max that a "B" and beyond battery will take is 333 Amps. 333 Amps * 0.083 milliOhm/foot = 28 milliVolts per foot. Given that the battery on an 85 is charging from 360 to 400 Volts or so, it would take a lot of feet to make any difference; even 100 feet would only be 2.8 Volts drop.

My guess is that there is no reason to change from the 250 mcm copper wire.

The long distance will be on the high voltage side of the 480V transformer, no?

I visited the site today. A security guard asked what I was doing, and I said I was waiting to charge. We both had a good laugh. Sadly, nothing new.

 

[Sluggo]

Stopped by today and construction for 10 charging stalls well underway.

On the other hand, the site has looked exactly this way (with no further progress) for about the past 3 months.

Actually work stopped only 4 weeks ago.

 

[gaswalla]

ok thanks.. I guess it feels like months.

It does feel that way.

 

[rrosenbl]

I will stop by on Monday, fingers crossed that at the lease some of the wood has been moved about....

 

[Sierra guy]

I was told by a security guard " end of the year" for SC

I was told by a security guard " end of the year" for SC

Did you also ask him why he said that? Any arguments for such a statement?

 

[ecarfan]

I doubt a security guard would have accurate information about the expected completion date of an SC.

BD is back working today. They told me the hold up was SCE. Tomorrow the chargers and the stations arrive. They still have to pour the slab for the switcher. They said that they will trench right through the 24 Hour Fitness construction site. 3 more weeks until finished.


I asked if they knew where in Los Angeles the next charger was going in, he had no idea. The man I was talking to said the next Supercharger he is working on is "somewhere north of San Francisco".

Great news.. Thanks for the update
