I agree.
Dual 40A chargers = 2 x 40A x 240V = 19,200W ~
19kW. Even "slow" Tesla Urban Superchargers deliver
72kW... and v3 Superchargers can deliver up to
250kW... so it sure seems doubtful to me that charging at 80A (
19kW) is a battery issue.
Supercharging
IMHO I think Tesla logically discontinued 80A (40A x 2) dual chargers due to:
- cost of the onboard dual chargers
- lack of customer need: home charging of even an almost empty battery overnight is possible on a the current 48A v3 Tesla Wall Connector
- installation of the older v1 Tesla Wall Connector ("HPWC) on a 100A circuit was expensive, confusing and difficult for Tesla customers since most homes can support a 100A breaker
- Tesla v1 Wall Connector plugs and cables got HOT when run at 80A. Been there, done that... replaced our v1 HPWC cable on a 100A / 240V circuit charging at 80A once already so I now charge at 60A to keep our v1 HPWC plug & cable plus our P85D's charging receptacle cooler so it last longer (HEAT KILLS plastics, cables, wires and electronics)
- customers buying 2 Teslas can't justify the electrical upgrade cost or don't have capacity on their main service panels for 2 Tesla Wall Connectors on 100A circuits. Newer v2 & v3 Tesla Wall Connectors can "share" a single breaker / circuit.
YMMV... and your opinion too.
Meanwhile back to the OP's now highjacked
