Prime's Charge Mode - Fast Charge?

Yes, for the European PiP this is only possible with a warm engine, electric only driving in HV mode.

 

I was likely going under 25 mph. The distance was perfect for running out just as I turned to enter the ramp... which is why I was paying such close attention.

 

I think it's absolutely great that they included charge mode !
If it just takes 30 min to get to 80% that's even greater and much faster as I thought it would be .
I will definitely use it from time to time !

 

The math doesn't work. Danny said the highway mileage dropped into the 40s when he put it into CHG mode. This works out to 4-5kW, not 9kW.

 

my engine comes on when i run out of ev, even if i'm going under 25 mph. unless the engine is warm.
i must have got a defective pip.

 

Same for me

 

Our grid mix is currently changing fast in my area. 10 years ago we were over 70% coal and less than 1% wind. Now we're less than 50% coal and more than 14% wind. During the life of the Prime the mix is highly likely to change further.

There are times now when wind can exceed 60% of our source mix, almost always at night. Load at night can thus allow more wind on the grid. BEVs can substantially help there and that's when the mix is cleanest.

 

i'm more concerned with petroleum use. we can clean up the grid if we desire to do so.

 

In the US, the majority of new renewable electric is wind. Then the majority of non-renewable going in is natural gas in the form of CCGT. These can be turned off and on rather quickly, and are most likely to be used if night time demand goes up in most regions.

Steam turbines, whether coal or nuclear, are the ones with issues in shutting down completely. Starting up takes time to boil the water and build up enough pressure. Shutting down runs the risk of water hammers in the steam lines. A ruptured steam line may do more than leak. So operators will basically give the electric away from these plants than shut them down. I don't have a problem with nuclear for base load until renewables, and the means of storing their excess can meet our needs.

 

A number of people I know have gone from anti nuclear to pro fourth generation nuclear after reading Prescription for the Planet by Tom Blees. The book describes the IFR developed in the USA which largely solves the problems of nuclear waste, safety, proliferation and cost.

 

I'd support one. I'd don't see our government actually passing one though.

 

I did the math for a relatively lousy mix of electricity fuels, and I got a surprising result. In this scenario, EV still produces less CO2/mile driven. I'm slightly suspicious of this result so I'm wondering if someone could check this for me.

 

Okay, my math was all correct, but my accuracy was not. Instead of using assumed efficiencies, I used actual average heating rates, measured grid efficiency and reported mix for my state (Colorado). Different result.

 

yes, and if there is concern for low income drivers, give them some sort of support based on the mpg of their car. but i agree with tb, there is very little political will, especially on the right. we are greatly influenced by oil pac's.
