is there any battery block in activate similar to matlab/simulink? If not is what is the next option to create battery modelling?

hi,

I did battery modelling in matlab/simulink.

when I am trying to import them its not working. Its showing error.

when I am trying to create manually, i couldnt find any battery or cell block. If I have missed the battery block, please let me know the block name. if its not there, then what are other options to create a battery pack for modelling?
