Supercharger - Chula Vista, CA (LIVE 4 Aug 2020, 16 V3 stalls)

[miimura]

Miimura... do you think SDGE will size the transformer for the full 16 X 250kw stalls or will they size for the initial 12? I ask the question because all of the San Diego Supercharging locations have been suffering from reduced output recently and with the first instance of V3, the expectation there should be good performance above 117kw V2. What size transformer for a 12 or 16 V3 stalls?

Each V3 cabinet can only draw 350kVA from the gird. They are interconnected with a DC bus that can move up to 575kW in or out of a given cabinet to reduce throttling as long as all stalls are not occupied and asking for high power. So, 16 stalls can only draw 1400kVA. 2500kVA transformers are very common, so that would be my bet.

Here is a copy of a photo taken of the cabinet rating label at the recently installed V3 site in Scotts Valley, CA.

Edit: why can't I insert the full image after attaching???

Any idea what could be delaying this SuperCharger from coming online? They started work on this months ago.

This Chula Vista Supercharger site has been dormant with no further construction for 3 months now. Disappointing.

 

[Axtrader]

They added some red tape to the poles and pedestal bases so people can see them better when maneuvering around the parking area but there has been zero construction progress since early November. There are an increasing number of new constructions SuC sites waiting on V3 equipment to arrive.... but I would also venture to guess that Tesla is also in a race for the best locations/sites against Electrify America (EA) and having secured these partially completed sites essentially locks EA out for the time being. Hopefully this site gets moving again and not drag on for several more months.

Over 3 months since the pedestals, conduit and cabinets were initially installed; 4 months with no construction around the corner in early March. San Diego is getting busy and could use some Supercharger relief. #1 in the US....

That’s a Hawthorne Supercharger screenshot credit to Derek Seaman at the San Diego TESLA Facebook page.

Probably the Kettleman City SC lounge area. It has a tv that shows that info

Riverside - Canyon Springs Pkwy, CA / Moreno Valley just opened with V3, so hopefully V3 is no longer the limiting factor...

 

[Axtrader]

Workers put up cones and barriers yesterday so I anticipate that they will resume work soon. I’m sure they will drop off cabinets and V3 equipment this week.

 

[Axtrader]

Lots of progress in only 24 hrs. Tesla installers are certainly becoming proficient at putting these in. Hopefully it wont take more than 2-3 weeks to get these inspected and turned on.

 

[Axtrader]

Two Chargepoint Level 2 chargers have been installed. Safety bollards were installed around the cabinets and extension poles are ready for new signs. No sign of the transformer yet but construction is progressing steadily.

 

[Axtrader]

Tesla signage has been installed and they have been wiring up the cabinets/pedestals this week. Hopefully, the transformer and wheel stops will be installed this week.

Quite amazing as Friars Rd is a 72 kW site, but perhaps that consistency is what gives it high discharge rates.

I was across from Hopewell Hong Kong about a month ago, I really wanted to check out that SuC as it's always on the top 10. but had no time to hunt it down in the parking structure.

 

[Axtrader]

Workers have been wiring up the pedestals and cabinets between rainshowers over the last few days. Also painted the signposts and bollards. Wiring must done as the support trailer is now gone and only the trash bin remains. All we need left are the wheel stops and transformer. Getting close. Hopefully the transformer is installed and gets inspected next week...

Thanks so much for all these informative updates and great pics Axtrader!

 

[Axtrader]

Covers on the pedestals are zip-tied in place, so the workers are still wiring them up. The transformer pad is empty but that will be done last. Stall line markers and the disabled stall need to be painted and wheels stops installed. Rain is forecasted for the entire week so we will probably lose another week on this project. Lets hope it is completed before it is influenced by the corona effect.

 

[Axtrader]

Wiring up the cabinets today.

 

[Axtrader]

All the wiring appears completed. The wheel stops were recently installed for each of the stalls. The Handicap parking stall needs blue paint. The garbage dumpster has been taken away. Looks like we need an inspection and then it will be ready to drop the transformer. Stay away Corona! Lets get this done.
