as it stands now, electric vehicles remain 'range limited'
because they are 'charging time limited'. in many respects.
i am not here to propose an idea so that stock investors for
tesla or some other fast charging stock bubble company
can attack me. i am here to propose a legitimate new
standard
for quoting a statistic that remains at the very
crux of the decision as to wether or not someone might
conisder an electric vehicle of any sort.
to begin with, because electric motors with discharging
batteries are efficient at accelerating per unit of waste
heat they
create----compared to combustion engines----the end
result is that the low end acceleration is so efficient that
the standard method by which the epa and dot use to
create various driving 'profiles' for detrmining the mile per
gallon of vehicles is not really relevant to electric cars.
the only profile you need to know about an electric car is
how much juice it uses at a given continuous speed
without acceleration. because an electric vehicle ,
electric scooter, bike or car---generally uses MORE
electricity at higher speeds, ---designers of vehicles should
consider explaining to people HOW MUCH electricity it
being used at a given speed.
because car drivers are generally interested in high way
speeds, you can use that as a top speed for measuring the
energy consumption. I personally am interested in high
speed electric bicycles which top out at 30 miles per hour.
NOW, once the consumption is determined at the speed,
the final calculation is to determine how many MINUTES
OF CHARGE are required to produce a MILE at that specific
highway speed.
i call it " charge time per X minute mile"
for example . if my batteries charge 1 killowatthour in 5
minutes ( a 12 kilowatt charger would do this) ,
and 1 kilowattshour gets me 5 miles at a speed of 30 miles
an
hour ----than that is "1 minute per 2 minute mile"
this is a statistic which sounds a bit complex, but it is a
very
concise and DIRECT METHOD OF EXPLAINING TO PEOPLE
HOW MUCH TIME IT WILL TAKE THEM TO BUY A CERTAIN
SPEED QUALIFIED RANGE. it CONTAINS THE NECESSARY
AND SUFFICIENT MEANING TO HELP YOU START
COMPARING VEHICLES IN A VERY MEANINGFUL WAY.

You have to consider the source. Be flattered that he considered the occasion worthy of capitols at all. |

Perhaps they weren't fixed on properly and all slipped down to the bottom when the screen got knocked? |
|
| |
Doesn't this get rather confusing if you use a super
charger on the way to visit your relatives, a 110V
15A outlet while visiting, and a 220V 50A outlet once
you get home? |
|
| |
OK! I'LL GET RIGHT ON IT. |
|
| |
It's also nonlinear. An empty battery will charge to
50% much quicker than it will charge from 50% to
100%. |

Well, they are much heavier. My laptop was half a kilo lighter when I formatted all the text files to lowercase. |
|
| |
Worst is when you do Japanese stuff, it's double-byte encoding, so all the capital kanji are 4 times the weight of regular lowercase Latin alphabet characters. |
|
| |
Thinking about it, surely it would depend on the viscosity of a halfbakery page? Then we could work out when teslaberry typed it... |
|
| |
Ok, here are some capital letters I typed at 00:40 JST (it's about 26 degrees C)...if someone wants to check tomorrow how far they are down the page that'd be handy. |

I'm kind of torn between many responses to this: |
|
| |
First is that most people would probably look at KWh per
mile or Km, which allows a calculation of how much is it
going to cost to go from A to B. |
|
| |
Second, the definition of the
speed/ acceleration/ deceleration cycle could be defined
for electric vehicles (ie wait 10 hrs to charge, coil up the
connection, air con off, tyres at max pressure, 2 people
and 3 beards). Then the energy consumption of the
vehicles can be compared. |
|
| |
Third, if I have a super-capacitor that charges quickly,
but is only capable of running the vehicle at fast speed
for a very short distance, it would have a good "minutes
per x minutes mile", but be a poor performer. |
|
| |
And I just thought of another non-linearity (well,
two really). Obviously wind resistance is non-
linear with speed, which means that a 1 minute
per 2 minute mile is probably going to be about 4
minutes per 1 minute mile, so choosing to vary the
speed is going to make the statistic questionable. |
|
| |
Also relevant, however, is that that non-linearity
isn't linear between vehicles. A vehicle with
horrible aerodynamics is going to suffer more as
the speed increases, meaning that SUV producers
are always going to rate at a lower speed. |
|
| |
mech-E. this is the whole point!!!!!!. |
|
| |
you give a car with 3 or 4 different speeds and
then provide the minutes of charging per mile AT
THAT SPEED. so you have an infographic for each
car used to compare to other cars so you know
how long it will take you to recharge as you travel. |
|
| |
of course-----you can also add the RANGE AT THAT
SPEED. each speed yields different range . |
|
| |
thus, you have more of a realistic basis for
comparison rather than the bullshit information
they currently give you . |
|
| |
Okay, then that's not exactly clear from the idea as
posted. I figured this was like MPG, which is a test
done under a particular set of conditions. |
|
| |
true, the aerosol spray can is a statement of level, science has delivered. |
|
| |
This idea is strange. It is like mixing the efficiency of your car with how fast you can pour gas in the tank. Though, I think everyone wants F1 fuel connectors. More time to read stories to the kids. |

No one drives at a constant speed. |
