Supercharger - Richmond, BC

[darth_vad3r]

If that's right, and it looks like there are 3 x 3 of those, it would be ~834 kW ... enough to supply 10 pedestals with a 5% loss factor and 5% overhead.

If there are 20, then there would be 2 of these cabinets?

Wait, I think for 3-phase Y ('wye') you have to divide by square root of 3 to get power, above is kVA? I dunno.

Someone who knows better, what's the math?

If I'm reading the power cabinet markings correctly: Each line out outputs at 480volts X 193 Amps = 92.6 kW.

This isn't unusual for a v2 supercharger. It means that if every single stall were in use by a Tesla with a low SOC and pre-heated battery, that they would max out at ~90kW rather than the usual higher charge rates. But outside of some organized and orchestrated event, that is unlikely to ever happen in the real world. Some cars will be closer to full and tapering and their excess power can be used to raise the charge rate of the cars with lower SOCs.

OK, lacking someone who knows better ... I *think* it works like this ...

600V wye is stepped down to 480V wye by this transformer.
480V wye is known as 480Y/277V ... 277V is the line to neutral voltage, and there are 3 of them. You can calculate the max power from those by 3 x 277V x current = 160 kW (for 193 amps)
It looks to be doing this 3 times (there are 3 supplies and 3 transformers in this cabinet).
So 3 x 160 kW = 480 kW.

I think there should be a couple more of these to power 20 pedestals.

20 x 72 kW urban would be 1,440 kW required min.

OK, I didn't calculate this ahead of time ... but ... 3 x 480 kW is exactly 1,440 kW ... so ya ... my bet is there should be 2 more of these cabinets to supply 20 x 72 kW of power (which can feed 20 x Urban Supercharger *OR* 20 power-sharing V2 Superchargers).

What's behind that green tarp in one of those photos ... could that be 2 more of these same cabinets stacked, or the equivalent?

This location is the same at the Blaine, WA location build, I believe it is a 150kW build just because of the stands. I don't think a V3 would be here because also the way that the pipes are. But who am I to say?

Yes Vader, I think the green tarp has at least 2 more cabinets, maybe bigger ones because it looked to be a considerable size*

Weekly update #3 it looks like there are some circle things in the ground, perhaps a canopy of being installed here? Solar in Rain-couver?

The "circle things" (Sonotubes) will be filled with concrete to make the bases for the pedestrian lamp posts.

Note: If you're actually crossing the fence line without permission to get these photos you should stop doing that.

Ah ok.

Will do, drone next time.

Looks like there's room for 2 more of those cabinets to make 3 total for 20 stalls worth of power like previously calculated...

Good calculations! Also it looked like another cabinet to the side beside the Richmond sign side.

Seems like a 4-pack according to the packing slip

"XFMR,
160 kVA,
600Vrms-480Vrms,
STPDWN, 4-PCK"
​

"4-pack of 160 kVA, 600V->480V stepdown transformers"

Is "Sonotube" for concrete forms like "Kleenex" for tissues? ... cuz those say "Greif EasyPour", not "Sonotube"

Yes, exactly like that.

I don't even own a Tesla yet.

When this gets built, how much is it going to cost?

Also, anyone know if the SuperStore (Richmond on no.3) DC charger is free to use or not?
How does the price/speed compare between Tesla SC and ChaDeMo?

There are a couple of free level 2 charger around the Richmond Center area, what's the thought of fully taking advantage of that to make your fill up completely free?

When this gets built, how much is it going to cost?

The Superchargers in BC are currently still on the per-minute pricing so it is ~$0.22-23/min for <60 kW and $0.45-46/min for >60 kW.

Also, anyone know if the SuperStore (Richmond on no.3) DC charger is free to use or not?

To use the (yes free, for now anyways) CHAdeMO at the Superstores, you need a $602 CAD CHAdeMO adapter. The speed is comparable (almost) to an Urban Supercharger which can do 72 kW. The CHAdeMO adapter itself caps you at 50 kW, even if the station could support faster (the ones at Superstore and other locations currently don't, I don't think).

If you have charging at home, it's not worth wasting your time driving around to Level 2's you don't need to normally visit just to get an hour or two of charging (2 hours at 6 kW is 12 kWh, which costs you $1.20 or $1.80 at home). If you want to do that to save $2 you can. It depends on how far you drive each day. If you don't drive a lot, and can replenish your use with a weekly 1-hour charge at the grocery store you normally shop at anyways, go for it. I don't think going places to charge is worth it if you can charge at work or at home, even if it costs.

Thanks for the reply, you are right, the Level 2 Charger won't be worth my time.
My apartment complex doesn't have an ev car port so I'm figuring out what I can do.

Lets say for a Model S 75D, I guess that charges at >60kW at ~0.45/min? (I dont really know how to quantify that... how much per full tank?)
I'm wondering how many times I have to charge at the SuperStores CHAdeMO to justify the $600 cost.

Planning to get a Tesla around Dec, hopefully the Richmond Center SC would be complete by then.

You should lobby the building owner/strata/landlord whomever to add EV charging support.
Do the same thing at work.

75D is *roughly* 75 kWh. If you try to charge all the way to 100% it slows down A LOT the higher the state of charge (SoC) goes. e.g. 20-50% is fast, 50-70% slows down, 70-80% slow, 80-90% really slow, 90-100% glacial.

This is all relative to Supercharging. Even at the end it's charging faster than L2 still ... but if you want the most bang for your per-minute-buck, you want to charge 20-60 say. This works well for trips. If you want to minimize your trips to the SC just to charge, you might charge for about half an hour from 20-90 say. That's ~70% of 75 kWh or 49 kWh. If you drive at 200 Wh/km that's ~250km. Super ballpark numbers. I don't have an S and don't know the actual capacity or consumption.

30 minutes would cost you $13.50 at $0.45/min.
The same ~49 kWh at home would cost you $4.90 at $0.10/kWh.

Supercharging isn't cheap. It's fast though, so it's great for trips. You really want to charge on L2 or even L1 when you aren't on a trip.

I volunteer myself as tribute to serve and protect all superchargers in the lower mainland of BC

It's worth noting that there are dozens of Chademo stations around the province if you want to road trip, many in locations not served by the Supercharging network (yet) and more on the way. They are either free, or have per kWh pricing that is comparable-ish to Supercharger rates.

If only Tesla 'allowed' us the use of a CCS adapter for a reasonable price.

I suppose their reason not to is financial and not technical.

Imagine an adapter for $99, that would allow access to CCS chargers across Canada, and not having to carry around that ridiculous almost $700 chademo monstrosity that serves a dying standard.

C'mon Tesla. Do the right thing.
