Morphology
The meaning 'a standard measure of electric charge' is directly derivable from combining 'charge' (the quantity of electric charge) with 'unit' (a measurement standard). The noun-noun compounding pattern 'X unit' is common and cross-linguistically transparent, so a B1 learner who knows both constituents would readily infer the MWE's meaning.
Etymology
The term charge unit comes from the simple idea of a fixed unit used to count how much electric charge there is, like using one cup to measure flour. So, the coulomb is a common charge unit we use as the standard amount to measure electric charge.
