Condition
Customer complains the Porsche Mobile Charger Connect (PMCC)
does not retain the ‘last mode’ power setting. For example, the
customer sets the charging power to 40A (100%), but it reverts
to 20A (50%) following a charger Sleep Cycle or following a power
cycle.
Technical Background
PMCC Communication Board (CommBoard) Software (SW) Version
3014 was released to address software bugs in SW version 2934,
e.g. “server authentication error”. Unfortunately, SW 3014 introduced
a new bug that can cause the PMCC to lose the desired “last mode”
setting for charging current / output in conjunction with PowerBoard
SW 4100 or lower. That means the power setting reverts to 50%
when the charger is unplugged or when the charger enters a sleep
cycle.
