More Dolphin information



The Dolphin controller appears to have two cut-off's. The system will not
draw more than 200amps at a time from the batteries, and the system will not
draw the batteries below 350 volts (10.0 vpc).

Typical highway motoring currents are around 60-70amps at 290-300 volts.
Flooring it doesn't seem to do much more than drive the amps up to 150-200;
the same results can be gotten by gently accelerating and going for accel on
downhills. This might be a limit of the single gear concept.

Is there a "tip list" for optimal EV driving anywhere? One question I have
is which is better: A bit of regen (which slows you down with your foot off
the pedal) or coasting (putting the car in neutral)? Is it better to let
speed decay a bit on hills, or keep speed constant with some power?
