Wp eines PV Panels ist genau definiert. Es ist die Leistung bei 1000W/m2 irradiance 90 grad zum panel bei ich glaube 20C Temperatur.
Bei einer Ladesäule brauchst du keine spezielle Definition das es wie schon gesagt eine glorifizierte Steckdose ist.

Es war aber ja nicht weniger. Der Lader hat eine Leistung von 1.1 MW erbracht. Das ist alles was die Zahl aussagt. Du willst das die Zahl die durchschnittliche Leistung über die gesamt lade Zeit aussagt. Das ist aber eine komplett andere Zahl.

Wenn das Auto zeitweise mit 350kW geladen hat ja. Wenn du präziser sein willst ist es „habe mit vorgewärmter Batterie von 10%- 65% mit 350kW geladen danach ist er auf 180kW abgefallen bis 80%. Das hat aber alles mit deinem Auto zu tun und nix mit der Ladesäule.

Hat dein 2kW Heizlüfter hat doch auch keine Erklärung das er auf niedriger Stufe weniger verbraucht. Das ist einfach impliziert.

Alle Batterien haben eine Lade Kurve die abhängig vom Ladezustand und Temperatur ist. Wenn die Säule mehr liefert als die Max Lade Spannung der Batterie dann wird die Ladekurve abgefahren. Wenn die Säule weniger liefert wird konstant geladen.

Und wenn du mit nem Taycan an ner 350kW Säule lädst zieht er nicht durchgehend 350kW.

Jeder E-Auto Fahrer weiß das seine Batterie eine spezielle Lade kurve hat und Max lade Geschwindigkeit ist nur für kurze Zeit erreichbar. Lade Säule gibt a was Max zur Verfügung steht, Auto/LKW entscheidet was die Batterie ab kann. Totaler nothing burger.

Two developed countries having a total blackout is a huge deal internationally. Everyone needs to understand what happened and what it means for their own grid.

If you plan it correctly you would do frequent stops of no more then 30min. My Silverado EV would do 7 stops with a total charging time of 3h for Houston-Boston. It’s longer than cannonballing it but in my opinion no nightmare.

After the downward movement what is getting the car back up so it can move down again? I rarely see cars just bouncing in parking lots.

Agreed, it’s a good discussion. It’s such a complex topic and difficult to break down in small chunks. And likewise I hope we can develop nuclear to a point where it overcomes the current short comings and is a no brainer to build out!

Yes because it would slow cars down increasing their energy consumption. There is no free lunch and the energy needs to come from somewhere.

But that’s all I’m trying to say. If nuclear was the cheapest and could be build anywhere we would do that. But it’s not and in a free market that means it has to compete with other sources. At the moment that is very difficult.

Levelized Cost of Electricity (LOCE) accounts for all that. Cost of construction, financing, maintenance, fuel and decommissioning over the lifetime of the asset divided by the total amount of electricity created. en.m.wikipedia.org/wiki/Leveliz...

I’m sorry but your statements are just not true. New capacity of Wind and Solar are cheaper then nuclear. That is reflected in the fact that most new capacity comes from those and any current new nuclear projects are a financial disaster. Read about Hinkle Point C.

The real answer is that there is no bigger environmental impact then the 1000 gCO2e/kWh. Coal is the most expensive way to create electricity, if you want to clean it up you replace it with LNG or demolish the plant.

Grid scale solar and wind is where it’s at. The EIA estimates that the Levelized Cost of Electricity (LOCE) for new capacity going online in 2025 is
34 $/MWh for wind
32 for solar
The last estimate for nuclear was 2022 with 90 $/MWh. Nuclear being the cheapest is simply not true anymore.

Potential sites for current nuclear plants are very hard to come by. You need a large body of water for cooling, low earthquake risk, and ideally low population density. With more heat waves and droughts especially the cooling water becomes a challenge for existing and new plants

Compared to what? You’d rather burn coal at 1000 gCO2e/kWh then use solar at 43? Extreme weather events due to climate warming will and have disrupted more ecosystems then solar ever will.

Nuclear and solar are both low carbon electricity sources when compared to combustion plants. NREL (National Renewable Energy Laboratory) puts the median lifecycle Greenhouse Gas emissions for nuclear at 13 gCO2e/kWh (read gram of CO2 equivalent per kWh)
Wind is at 13, solar at 43. Coal is 1000.

It’s around the spots of highest intensity. The bleeding over happens in the sensor in the satellite. The equivalent of overexposing your camera sensor until you get artifacts.
