I agree that trying to dynamically switch this without a carefully designed bespoke solution would be extremely dangerous, as a 240V input could easily be detected as 120V for a brief period during plug-in. In my opinion you need to sample the voltage for at least 1 second before making a decision which circuit to enable. I wouldn't dream of doing anything but buying a new charger with a wide voltage input though.
circuit detect if I'm getting L1 or L2 charging

I don't think you need custom electronics - especially built by someone with little clue what they're doing - but I agree that the right switch logic (e.g. normally closed contacts power the higher-voltage charger, which is the reverse of the example that I showed) with suitable settling time is required. There are catalogs full of 250 VAC switching devices, and one is likely suitable - it would be worth a look for anyone seriously interested in an automatic switching solution.
Same here, and probably with everyone except the original poster.
This would definitely work if it defaulted to the 240V option and had a reasonable settling time.
I wouldn't quite trust it, but it would work.

You can buy 10 wide-voltage onboard chargers for the cost of smoking one J1772 charger.
Again - it's ILLEGAL to design such a device for use in a public living space.
What you do at home is between you and your god of choice, but burning down an apartment complex with your unattended rat's nest of wiring is a different matter.
