Supercharger - Loomis, CA (LIVE 2 Apr 2021, 8 V3 stalls)

[Zorg]

Used it last night for the first time on our way up the mountains. Super practical: right off the freeway, and walking distance to 2 food joints, a Starbucks and Raleys'. Can't complain. Being a V3 charger is icing on the cake.

Does the Raley’s have a restroom, if so what side of the store. I looked a couple months ago and I couldn’t find it. Thx.

I imagine that they do (at least for their employees!). We stopped at Loomis a couple weeks back and used the restroom at Taco Bell, and picked up a bean burrito.

Starbucks does as well

Enter on the left entrance to the store - restroom is just inside, very close to that entrance.

We use this location often on the way to Tahoe and on our last visit noticed that the charging stalls had been made wider.
They were super tight for our bikes on the rack before and now have 1.5 feet to spare. You could see the old line markings painted over and pedestal locations patched. I wonder if these is preparation for the CyberTruck and if its happening at other locations?

Also we find the Round Table pizza there is pretty good.

We used this location also going to Tahoe, great location, easy to get to and nice food/break options nearby.

However I am confused about charging rates, I picked this SC over Rocklin (which was rec'd by nav) because it was 250kW. But I never got anything close to that; at best I was charging at 70-80kW IIRC. It was around 40-50F and the car had SC as destination and plenty of time/driving to precondition (MYP). I figured it was due to the temps, or due to too many cars at the same time? Fast forward a few weeks ago taking a long route back from Tahoe City, stopped at stateline to charge at the Hard Rock Casino SC, temperature around 20F, and I was getting 120-150kW. Topped off before we could finish peeing and get a cup of tea .

Does anyone know if some SC can't support multiple cars at max power? It seems the rate isn't purely temperature or or preconditioning related?

What was your SOC?

 

[Zorg]

If SC was full, it's most likely due to sharing the power available

There are no Superchargers that can support full power to all cars simultaneously. For example, 8-stall sites are typically hooked to a 750 kVA transformer - if full, each car would get 93.75 kW. I've seen 8-stall V3 sites hooked up to 500 kVA transformers, which is even more limiting at just 62.5 kW per vehicle. The worst example of this is Aiea, Hawaii, which I believe is hooked to 300 kVA worth of transformers for a 6-stall site - it's almost always full and users regularly report charging speeds of around 50-60 kW despite being a V3.

Thanks for the replies. SOC was around 45%. It makes sense that it's the transformer capacity, good to know if you're in a real time crunch. V3 at full 250kW is like cocaine for your car .

FWIW, utility transformers won’t limit power output. They can be loaded to 125%, 150%, even 200% of nameplate rating. The drawback is the more overloaded they are for longer periods of time, the shorter lifespan they’ll have. That is why it’s on utilities to size transformers properly. In extreme overloading cases, fuses will blow or protective devices will open on transformers and other line devices but that’s more likely with fault current conditions on the order of 10X normal load.

Also at a V3 site, it’s unlikely 8 (or 12 or 16, etc.) newer Teslas would arrive exactly at the same time with a preheated battery at 10%, all asking for 250 kW. The V3 shared design works well because of load diversity: perhaps one or two arriving asking for 250 kW, a couple others asking for 75 kW, and one almost full only wanting 45 kW, and so on.

Agreed on all points. Based on my observations, Tesla seems to set their site maximum power draw to respect the nameplate rating on the transformer(s).
