“Well here is someone who disagrees.”
That is for phones, not EV’s.
Live and learn.
“efficiency of led bulbs have been preached also. But every good long term led bulb I examine has a huge heat sink and heat dissipation system when it is of size.”
ROTFLMAO!
ROTFLMAO!
Read the WHOLE article. There is a comparable efficiency at a VERY PARTICULAR RANGE OF CHARGING, and that is a very LOW range of charging.
They quote 20% to 80% state of charge. Why the range? It is time sensitive. How confident are you going to be with a 20% charge? Of course eyes go to the 80, but there is also a 20.
“Level 2 home charger operates in the range of about 83-94% efficiency grid-to-battery depending on which one you buy.” Now that is quite a loss of efficiency to compare to. THAT IS A HUGE LOSS OF EFFICIENCY TO CONVERT ENERGY.
Now regarding cell phones. No one is going to wait a whole day for efficient charging, It is a lower power consumption and we can trade efficiency for convenience. Add another 5-10% efficiency cost to a EV for convenient/ fast charging, and there are problems and cost factors that get serious.
Now don’t laugh at the LED bulbs. Yes, the old led on the calculators were almost 100% efficiency. That was the selling point, but achieving in application and manufacture is another point. That does not mean all LED’s lights are efficient. Take a look at the higher wattage or long lived bulbs. They have massive heat dissipation systems. HEAT is inefficiency.
The short lived “fashion” when I grew up was “appropriate technology.” It was understood that in certain situation certain technology was a good thing. IF you changed some aspect of the system things changed.
Liberals look at one or two data points of a complex system like climate and think they understand it and can control it.
I am not against EV, they are appropriate for some people and some situations. But note the govt thinks one size fits all and will force you one way or the other. and in their “one size fits all”, THEY MAKE THINGS WORSE.
