Morphology

battery + pack

The meaning 'a portable unit consisting of one or more batteries used to power electronic devices' is directly derivable from combining 'battery' (an electrochemical cell) with 'pack' (a packaged bundle or unit). This noun+noun compounding is a regular, compositional pattern found across languages and technical vocabulary, so a B1 learner who knows both constituents will readily infer the MWE meaning.

Etymology

Battery pack comes from a simple image: a battery or a small group of batteries in a pack you can carry. Imagine a little bundle you take with you to give power to a phone or camera, and that's why it means a portable unit used 'to power electronic devices'.
