Charging Two EVs with One Charger

I had a level 2 charger installed for my BMW I8 through the electric company (XCEL) and my wife is getting an EQS SUV. I charge overnight to get optimal rates. What are the best methods or times to charge two EVs with one charger? Or should I have another charger installed? Can one install two chargers on a 50 amp circuit?

It could be wired to have two chargers on one circuit but it will take twice as long to change as the current is shared between the two. If it was me I would have another 50A circuit installed with its own charger.

Charge your i8 with a level 1 charger.
If you are planning to replace your i8 with a real EV then you will need to install a 2nd circuit or replace your current EVSE with something like this dual Charger from ClipperCreek

Anytime you have two chargers hooked up to one 240 v circuit the currents are shared between the two chargers make it longer to charge your cars. Same principal when charging on public charge stations. I noticed when I'm charging by myself, I get over 110KwH but once someone hooked up next to me it goes down to 60-93 KwH.
