Does anyone know what the ac compressor actually draws power wise? I thought I read 1.5kw. Also what voltage does it run on? I would assume 300+ volts or is there some other off converter in there just for the compressor?

Yes, the resistance in the back increases as it ages. I don't think I've seen anyone test or estimate what kind of actual impact on efficiency that has though. This also means that more heat is added to the battery as it charges and discharges but again not sure if that impact is great enough to be significant.brycenesbitt said:Is there an efficiency difference between new and old battery packs?
In other words, for a given number of miles driven, does an older leaf end up using more electricity?

BrockWI said:I sometimes set our EVSE to 240vac at 6 amps
Mine will also go down to 6a, I only did it once for a test but it was 6a, any lower and it wouldn't charge.BrockWI said:Mine does, I do it all the time, I just went and checked it again and it is set to 6 amps @ 240 volt.

First I thought I could use a battery and an inverter to charge at 200 watts or so, but it sounds like that would not even cover the charging overhead? Maybe I can charge the battery and use a bigger inverter to charge closer to 1200 watts? Thoughts? Thanks for all the number crunching and sharing! It's been a big help!
