Electrician here. Have you checked if the existing wire is aluminum or copper?

It's quite common to run #6 aluminum instead of #8 copper for 40 or 50a circuits because of the cost savings.

If it is aluminum you'll need to use proper connectors to junction to copper but really if possible it's most likely the simplest to just run the 6/3 straight to the charger.

It is copper, thanks for the heads up though.

This is how my electrician did our EV charger. Pulled the 6/3 Alum from the old hot tub connection and ran it to the EV charger with copper junctions. Ours is on a 60A breaker and we get 48A to the Tesla.
