ANA main battery smoke

TURIN (# 181)

A failure in the diode module (typical is short circuit) may explain the smoke ATC saw.

APU circuitry doesn´t require the diode as you understand (APU batt. never is directly connected to a supply. Just to loads: APU starter, through the modules you mentioned or to the lights when towing with APU ON). The charging of APU battery is not normally made during her only two above mentioned uses as we can imagine.
