extended PIH like the Volt,
you can have the crank anywhere - far away from the hub,
Most state laws define an e-Bike as requiring fully operable pedals.
They do not say *how* the pedals should operate, but if you can turn
the pedals and move the bike, without additional motor power (even
if that means pedals -> generator -> motor -> wheels) that should
qualify as e-Bike. One way t
Buddy,
You can use one of the Schottky diodes that is ideal for this
architecture,
typically they come in a block with 2 diodes integrated and ready to
mount to a heatsink, the only thing you need to take care of is to
insulate the diode housing from the chassis of your vehicle as the
housing has t
This is a question that comes up from time to time, especially when my
colleagues see the bike I ride to work and casually ask how long the
ride is, after which we often find out that I ride father to work than
they drive
so they get to scratch their heads and wonder if they might start
biking
Like so many other EV'ers, we have found the semi-ideal solution in
having an EV (rather short range, but I can manage over 95% of my trips
fine) in addition to the Prius which is my wife's favorite car.
Everybody happy.

Ehhh - the *internal* wiring of an EVSE, how can that be a standards
thing?
Who cares if the charging cable has copper, steel or aluminum wiring, as
long as it meets the current spec (and possibly the max resistance if
that is important (voltage drop)?

Lee,
"Internal" as in anything between the external interfaces.
So yeah - in this case the wire that connects the J1772 coupler to the
housing.
Note that using steel cable and even getting somewhat close to the same
resistance would make the cable several times heavier and stiffer, so
much more dif
I did not use a mounting block,
I attached the fuse directly to the post clamp on my first battery
and attached the cable lug to the other side of the fuse instead of
to the battery post clamp.

This appears to fit the 700A and 800A fuses, but we are getting there!
Good find.

case. These are strong, and won't melt or burn if the fuse
has to clear a dead short.

I recently bought a cordless weed whacker, it came with NiCd batteries.
I only found out once I started studying the user manual, I was
expecting Li-Ion cells.
