I see what you're saying, I didn't know it started after a year... but still, I would imagine that all the knowledge Bats has on Superman are from military documents and video footage, never really meeting or talking to Superman.If BvS is to start a year after MOS as they say, I see now plausible explanation why Batman would not have some info on this flying man, he left enough clues for that to happen. I'm not saying that Batman should know everything about Superman (fortress, Kryptonite) but he should have enough.
If anything it should be Lex that forms a shadowy UN type deal.
Batman should have no knowledge that Kryptonite is Supermans weakness at this point, and Superman was the only person to give him the Kryptonite I believe.
So at this point, Batman should be worried because he has no legit way on defeating someone like Superman
