When my wife and I built our house 2020 we knew we eventually wanted to get a second tesla. At the time we had a model 3 (still do) and a minivan. We had the builder put in a 100amp subpanel off our main electrical box right near the garage in the basement, and ran a wire rated for 60amps from that sub panel to the wall charger right above it into the garage. The Tesla Wall charger I have is from 2018 and is a Gen2 unit. Does anyone know if I can power share between a Gen2 Wall Charger and a Gen3 Wall Charger like is seen between Gen2 units here? Load Sharing - TESLA Wall Connector
We are trading our minivan in for a 7-seater Model Y this coming Saturday. I purchased a new Gen3 Tesla Wall charger. My thought is to put another 60amp breaker and wire run out of the sub-panel to this new second wall charger in the garage. Then, set the charge limit to 40amps on both. This ensures that if both vehicles are charging fully, the most draw they will have is 80amps, which is still 20% of the 100amp breaker in the main panel which the sub-panel comes off of. Each car can technically charge at 48amps if the other is not charging since each will have a 60amp rated line and breaker in the sub-panel. So, if we need that extra little speed burst, I could change it to 48amps - but I doubt it'll ever be needed.
Does this sound like a good plan? Am I missing something that would simplify this in some way? Thanks!
