New Audi E-Tron GT

[MReda]

The simplest explanation for the "delay" with the maxpack is that Rivian can make 4 vehicles with a large pack for every 3 vehicles it could make with a maxpack. Therefore, they are prioritizing the large pack to maximize the number of vehicles they can deliver. There's no reason to believe that the maxpack is coming with any additional features beyond what the launch vehicles will have.

Agreed, they are supply constrained in general and it is reasonable to assume it is also on the battery supply, so smaller batteries means more vehicles.

Ben Sullins did a good breakdown of the Audi GT specs with comparisons to both Porche Taycan & Tesla Model S.

Not sure it is in the LE, the advertised rate of 140 miles in 20 minutes is in line with 200KW 400V charging rate. I believe the 300KW charging is not coming until the Max Pack is introduced.

It is equivalent to 200 kW charging at 800V, 900V, 120V, 240V or any other voltage you want to specify. Lower voltages will require higher amperage to get to the 200 kW and therefor heavier cables both on the charging equipment and internally to the vehicle.

The CCS standard does not define a 200 kW charge rate at 500V or less, nor do the current chargers on the market support it. In order to get anything above 150kW they have to support a rate >500V.

I understand that 400V is not the limiting factor and should have left that off.

But, CCS does support 500A at 400V, and that is the limit of 200KW at 400V. I just looked at a Signet charger at an EA site and they support the full 500A. The ABB units I have seen only support 450A. GM has specified the Ultium batteries with 400V architecture support 200KW charging and the Ultium with 800V architecture support 350KW. This is representative of the CCS standard.

Independent of voltage, assuming a 300 mile full range charge, 140 miles is .47 of a full battery. Assuming the estimate of 135KW that is 63KW. 63KW/200KW*60minutes = 19 minutes of charging at 200KW. That is not 300KW charging.

I thought they said their adventure stations would charge 140 miles in 20 mins, not the cars limits?

Doesn’t Tesla still rely on a 400 V architecture and manage up to 250 Kw? I guess I don’t understand enough about the charging aspect to electric cars to see what difference architectures make, and why they would even do at 800 V if they could just increase the amperage at 400 or 450V? I know Lucid has a 900 V, GM is doing 800 V for all of their heavy duty full size vehicles, and Hyundai/Kia is doing all 800 V, so there must be another reason for the higher voltage if charging rate isn’t a factor if you have higher amperage like you said.

I have read Rivian would allow up to 300 Kw in the past, but I always thought that required an 800 V architecture like the Porsche Taycan. It looks like for now they’re going to be starting off with capping it at 200 kW.

I am a complete layman when it comes to this subject, so please excuse any ignorance.

The maximum current specification for CCS connectors is 500A. That also requires liquid cooled cables and connector in the charger. Tesla is proprietary and is pushing 625A. To get 350KW, you need at least 700V (700V*500A=350KW). At 400V and 500A, that is 200KW.

It is not clear that they ever differentiate capability versus networks on the web site.

For what its worth, the Rivian DC Charger plans that the City of Salida published on the internet last December included the following information:

DC output:
Voltage range 200-920V
Dispenser power 500A
Power (peak/ continuous) 300 kW/ 300 kW

It is a really nice looking vehicle and has the appeal both inside and out over the Tesla, but that is just an taste thing. If Audi would just buy better battery tech and get this to be 330-360 miles it would be a killer. All the reports of the Etron getting 200 worries me this will be the same. Not spending that money to get that when a Rivian or a Lucid will get way more and be just as attractive.

In testing the Taycan generally got same or better range of epa even at high speeds which I can’t say for Tesla. So the 280 etron gt is probably a good prospect given its faster charging curve.
