At the recharging station an extremely short wait is needed
to attach the recharging unit. The batteries are recharged
on
the fly, and at the next station an even shorter period is
needed to discard the recharging unit, and continue on.
[edited] Forgot to say the most important part: The
charging
unit is an auxiliary battery with higher voltage
than the in car battery. It passes the energy to the original
battery.

I think you're gonna have to explain what a "recharging unit" is. |
|
| |
Oh, the "recharging station" is an auxiliary battery that you hook onto your electric car so it can recharge the main battery while you drive? |
|
| |
If you're going to stop at a recharging station and do physical stuff (attach 'recharging unit'), you may as well just swap out the depleted batteries for a fresh, charged set. Less farting around, good to go.
You just need to create a 'Standard' size/position/mechanism so all vehicles can use the same system; which would be the most difficult part. |
|
| |
[shadow], But this will work without changing
anything. One stop you add it (with a bit of hassle)
the next you drop it (no hassle). |
|
| |
Its a different solution and perhaps a better one
than
swapping the depleted batteries for fresh ones -
with each car having a different size, and shape
and
whatever... |
|
| |
The best part of it is the next stage, where there
are no stations at all and this really done "on the
fly" connecting a trailer to your EV (this would
work better for a bus or truck) |
|
| |
Anyway: I love this idea, and call on my friends to
please remove the bones, and give me sugarless croissants (did I spell that correctly?). |
|
| |
Higher voltage batteries wouldn't be necessary
(electronic charging from any voltage is fairly
efficient these days.) |
|
| |
But you'll run into lots of difficulties with energy
density (i.e. how big and how heavy will the
"recharging unit" be? Presumably at least as large
and heavy as the batteries you're trying to
recharge.) |
|
| |
And trailer or not, you're going to be moving twice
the battery mass with no additional energy
available. |
|
| |
In the extreme case, a huge trailer with 10x the
energy of the original batteries would be sure to
recharge the batteries while at rest, but be
impractical to be towed by the motor of the car
(which was presumably optimally sized to propel
the car, not (car + huge trailer.) |
|
| |
Sorry, my fishbone remains. |
|
| |
It's a novel paradigm, workable or not; here have a croissant. |
|
| |
Got me thinking: Can a countercurrent exchange
mechanism be used for rapid recharging? |
|
| |
a. The trailer can be self propelling. |
|
| |
b. No: Voltage is the
issue, therefore not necessarily larger than the
recharged bat. |
|
| |
c. Many stations would make for a
system like the Persian mail system (or pony
express) so no expensive long distance batteries
are needed. In that case of course the recharge
must have at least enough energy till the next
change and a bit more. |
