Why is an EV's backup power less than it's driving power?

Not really. 3 to 4 mi/kwhr is the standard display on screen. We, the EV drivers, are all well familiar with that number. From driving 60 miles in an hour, we can determine that 20 kwhr are consumed. So, the average number of 3 MPH per KW is derivated.

If I were to switch the governor bit off, my Audi can go 156 MPH. Well, the ski rack might slow it down a tad.

I don't think I've ever driven a car over 120, and that was enough.

That's like miles per gallon. But you were talking about SPEED. Go read your post.

And stop deleting newsgroups where others are reading the conversation.

WTF? Governors are set to 155, that's the EU agreement. So yours limits you by 1mph?

I went 140 in a rental car, it was great fun. And not enough, I was still accelerating but there were slow French drivers ahead doing about 95.

I've never owned a car that will go over 120.

I wouldn't call it "efficiency". It is mileage, just like gasoline mileage, miles per gallon vs. miles per kWh.

I don't know why you respond to Kinky. He will never acknowledge when he is wrong. It's like wrestling a pig. You both get dirty, but the pig enjoys it.

I'm not stupid enough to pay the daft prices. Sell them at the same price as petrol cars, then I'll buy one. They need more people like you paying through the nose to recover the design costs first.

I thought the Leaf would get more like 4 m/kWr. My boat model X gets 3 m/kWh. The model 3 gets 4 m/kWh and some people claim closer to 5 m/kWr, I suppose their driving is less highway.

I think it's an issue of significant digits, but my car displays Wh/mi rather than m/kWh. Still, it's the same measurement and is typically around 333 kWh/mi, but does run higher when I'm hitting 70+.

They are related. My EV just happen to get around 60MPH with 20kwhr. Saying that the original qualifier is "wrong twice" is double misleading.

You are the one deleting my statement: "We, the EV drivers, are all well familiar with that number. From driving 60 miles in an hour, we can determine that 20 kwhr are consumed. So, the average number of 3 MPH per KW is derived."

Uh, oh! That's 1!

Miles per kWh is distance per capacity. Mph per kW is speed per power output. Absolutely not the same thing in any way whatsoever.

You did it again, learn how to post to multiple newsgroups. I've fixed it for you. Now grow up.

You deleted your own statement earlier, then tried to refer to it.

Perhaps 3.5 mi/kwhr at constant 40MPH. That seems to be the most efficient. At higher speed, wind draft is significant. At lower speed or stop and go, the 100W power relay alone is also an important power hog.

I am just using 3 as simple illustration for 20kW (60MPH and 20kWhr)

File a complain with Google. I didn't do anything other than using Google group. You and enough people are seeing my posts. I don't care if it doesn't spread all over the world.

But i am saying the same thing.

Better yet. Buy Google and fix it.

Sounds like a crap design. Have they not heard of latching relays?

Wow! You did it again! Up there you said "3 to 4 mi/kwhr", and now you say "60MPH and 20kWhr". Learn the difference between miles and miles per hour.

Newsgroup list repaired. Again.

Google groups! ROTFPMSL! Get a newsreader. It's a program you install on your computer. WTF, do you use webmail too? Are you over the age of 6?

Might have to just killfile google groups. It would raise the IQ of the group significantly.

No you're not, you're changing two units. You might aswell write your lightbulb uses two elephants per minute.

Yes and yes. Not that it matter much. They works well enough for me.

Yes, please do so. You can be out of my world and I am out of yours.

Well, you are stretching it too much.

In the UK we have a genuine 240V 100A 24kW supply in every home. No having to use the right amount on each half of the phase. No extra cables running around the house for the extra live. No choosing which socket has the right power for the device. Plug anything in anywhere. And they all have an earth, and they all have sleeved pins. No wonder you guys are fussy about safety. Put the plug in clumsily and you short live and neutral through your hand. Ouch.

For heavy shop (I assume you meant workshop, a shop is where you sell things) tools, we get three phase. 3 times 240V = 72kW.

ROFL! Extra thick cable for no reason. My AC is 240V 8A.

One of the car mags reported 156. There is also a report of someone who made 159 in the 3.2L V6 like mine.

This being the USA, I'm not sure what the governor is set to.

You sure are nasty.

I'm telling you, you will never get any traction with him. He is very learning resistant.
