Why the battery connected on the load side for storing purpose is taking the volatge /current at whatever rating it is given in matlab simulation?

I am designing a DAB DC DC Converter and when I am connecting a battery block in Matlab and fix its specification lets say 350 V and 25 A, when I am giving input as 600V, Battery would charge to...
