So I'm trying to get my head around how this is working. I just ordered some power supplies that put out 90V each to make an Insight grid charger. They are put in series for 180V max. The car uses a 144V pack. Obviously the voltage goes up and down a fair amount in normal usage.

My question is why do we aim for a 180V output on the charger side? Is it simply a case of they can go to 180V and that is above what the pack will ever charge to, thus they can provide the full current to that voltage?
