This one is going in near me, sure looks like some of the CCS will be 350KW, some 150KW and a lonely 50 KW Chademo, based on the annotation.

What vehicles right now can use 350 KW CCS?

None, but the Taycan will be able to charge at 270kW out of the gate, and as batteries get bigger/able to accept higher C rates there'll be cars that can use it. Porsche is talking about 400-500kW down the road, which won't be possible for 800 volt packs as long as the stations are limited to 350A, i.e. no more than 280kW, but if the input/output is the max. of 350A @ 950V, the AC/DC placard limits on the BTC chargers I looked at in Castro Valley, they could output up to 332.5kW (assuming a PF of 1.0).

Re the above, via GCC:
Electrify America network first to charge 800V EV battery at 270 kW
https://www.greencarcongress.com/2019/0 ... 10-ea.html

. . . On 4 September, the day of the global launch event, a Porsche Taycan, with its 800-volt architecture, charged at Electrify America’s Bloomsburg, PA charging station. The vehicle charged at a maximum power level of 270 kilowatts, the fastest charging speed for passenger vehicles on the road today.

The vehicle, which drove approximately 250 miles directly from Niagara Falls, utilized Electrify America’s 350 kW chargers to obtain a 5 percent to 80 percent charge in just 22.5 minutes. . . .

^^ I'll guess that the Porsche drove the 250 miles starting from 100% and ending at 5% for a trip range of 250/0.95 = 263 miles.
Then it charged 75% of its range in 22 minutes, which works out to (263*0.75)/22 = 9 miles a minute charge rate.

Not bad at all, but nowhere near Tesla performance in a Model 3 that costs 1/3 as much.

Keep at it, Porsche

Richmond, VA (I-95 ex. 83A/B @ Jct. S.R. 73, on U.S. 1) is open, #3 for the month and #288 total.

This shortens what had been one of the longest remaining legs on I-95, the 134 miles between Stafford and Emporia, VA, to two legs of 62 and 73 miles. It also shortens the 121 mile leg between Zion Crossroads and Newport News, VA via I-64/295/64 to two legs of 52 and 71 miles.

Anyone know what the hold up is on the EA chargers on CA, especially along 395?

Seems like bishop, coso junction and mojave are just sitting there mostly done.

Utility needs to install the transformers and such

Utility crews are busy doing fire season risk reduction.

After fire season, perhaps.

Was reported several weeks ago that utilities were concentrating on wildfires and installs were on the back burner.

Makes sense

No, that was the past two years - this year they're concentrating on keeping them from starting. :roll:


Two more sites have opened, making 5 for the month and 290 total: Yreka, CA (I-5 ex. 773, Jct. with S.R. 3); Turlock, CA (S.R. 99 ex. 214).

Yreka extends I-5 south from Grant's Pass in Oregon. We still need Anderson (preferred) and/or Willows to open to complete it as far as Sacramento.

Turlock shortens the 132 mile leg between Elk Grove and Madera to two legs of 73 and 60 miles.

With the opening of these two California takes the lead, which should never be relinquished, from Texas as the state with the most open EA QC sites, 29 and counting.
