Audi TT conversion
Posted: Sun Jan 08, 2012 1:42 pm
Can anyone clearly define the difference between an AC or DC system I'm in the process of converting a Mk 1 Audi TT to electric, but seem to be going around in circles as regards component choice. For now batteries will probably be lead acid 12x12 volt 150ah 144 volt pack I hope to design bat boxes to allow refit to lithium when prices are sensible!
My initial thoughts were to use DC Kostov 10" motor with Curtis or maybe zapi controller,but many people are advising going with AC motor/controller trouble is there doesn't seem to be much options out there for the DIY project.
As I see it the main difference is regen and slightly better efficiency with AC, is this correct?Also are DC motors ok for climbing hills compared to AC.
All I have really found available AC, is a USA AC-50 motor with Curtis 1238r controller but this is only 96 volt so I think under powered?
My goal is to make TT as light as possible have minimum 40 mile range to sensible DOD with acceptable performance around town driving and some hill climbing 50 to 60 mph top speed.
Looking for advice, guidance, thoughts, ANYTHING.
