The Prius uses nickel metal hydride batteries and the control system
makes sure they cycle between 30% and about 80% charge. That is why
they have such a long lifetime.
You aren't going to be able to do this in an electric powered sailplane.
That said, the replacement cost of a set of batteries for the Antares
is I think now around Euro 15000. Not all that bad when you consider
the cost of the sailplane. We'll get to see soon how many years the
battery packs last in that thing.
The problem with cars is: how much do you spend on a 13 year old car
which probably is worth only a few thousand dollars?
One thought about the ASG32EL 100km range........ as long as you
aren't in the next valley from home in the Alps :-) Nice looking
glider though.
Aviation is about to get interesting see http://www.jobyaviation.com
They've moved away from the earlier tilt wing Sparrowhawk concept.
One drone manufacturer has made the drone VTOL by basically
strapping an electric quadcopter to it.
Hybrid air vehicles make sense that way. Electric, multiply redundant
lift motors which only need to run for short periods (hence small
batteries) and small piston engines sized for cruise in a vehicle
with very small wings as you don't size them for takeoff and landing
and low stall speed.

My NHW-11 at 280,000 km (13 years) threw the battery code, and a
$3,500 replacement now has me expecting to exceed 0.5mill km before
the next replacement.
Thus, totally in line with conventional vehicle expectation of time
use inclusions like transmissions,
in this case 2c/km amortisation cost.

I heard a horror story last week from the owner of a Toyota Priapsis
which had a failed battery. The cost of replacement was so high that
he had to sell an otherwise roadworthy car for spares. But the
lifespan of a Toyota is not the same as a sailplane.
