Charge most nights at home, just fine, inside my garage. NEMA 14-50, 6 gauge wired. Charges at 39/40 or 40/40 amp for hours and most nights. But, sometimes it drops to 30! I called the road side # and they said call local center when it happens. I did. Goes in Monday for a small list of issues. I can't figure out why its dropping. 50 amp breaker. Total of 2' run. It's litterally 1' below my main breaker. It does get warm though, and I wanted to see temps you guys have. I used my trusty Harbor Freight contact less infrared laser pointer thermometer to finally get some readings. After approx 6 hours of 40 amp charging: (F) in order of wall --> car. NEMA wall outlet: 97.7 Mobile connector to NEMA 14-50 adapter: 134.9 mobile connector 'end': 142.1 green light cylon part: 91.4 wire near connector at car: 80.7 garage air temp: 55 is this normal? I cleaned all connectors/connections. The NEMA 14-50 is a month old. My house is propane heat, so the furnace is not going to draw anything against my 200 amp service. Well pump shouldn't cause issue. Even my stove is propane. And hot water heater. Only the dryer might be a load, but I can't find any rhyme or reason for the power drops. 90% of the time it rides 40 amps all night... Well I should say my daily commute means only 2-3 hours of charging. I haven't enough data yet to know if it's dropping to 30 amps after 4-6 hours. If i run that visible tesla app, will it give me more insight to the charging amps over time? thanks guys. I just want to know if it's the car, charger (I do have dual) or the house. I can't see putting in a HPWC if I can't even rock a steady 40 amps. Nor does my normal commute require one.
