A Kapranov–Voevodsky 2-vector space is a kind of 2-vector space, in this case a category equivalent to Vect${}^n$ for some finite $n$. For details, see:

There is also a more abstract characterization of Kapranov–Voevodsky 2-vector spaces, described here:

Namely, they are semisimple $k$-linear abelian categories with finitely many simple objects. We may also drop the finiteness condition here to define a class of ‘infinite-dimensional’ Kapranov–Voevodsky 2-vector spaces. For further discussion and more references, see:
