Condition
Duplication and diagnosis of customer AC charging complaints can be difficult without detailed information from
the customer and the charging hardware provider. The following documentation aims to assist Porsche Center
service and support personnel with relevant and necessary information to assist customers with AC charging
complaints.

Technical Background
The level of data captured differs amongst the various charging components offered by Porsche.
Diagnosis of the Porsche Mobile Charger (PMC) labeled the Porsche Universal Charger (PUC) and the Porsche
Mobile Charger Plus (PMC+) must be performed using the PIWIS Tester and diagnostic adapters provided as
Porsche Special Tools.
The Porsche Mobile Charger Connect (PMCC) control unit is equipped with additional sensors and function

Diagnostic Troubleshooting Tips
•
AC charging concerns should be checked with customer-supplied charging hardware (supply cable, ICCPD,

and vehicle cable, for example)

•
The infrastructure that supplies customer homes and garages often differs from the infrastructure

in a Porsche Center or other commercial building. For example, customer homes are typically

single-phase and operate at 240 VAC, whereas commercial buildings are often three-phase and

provide split-phase to 208 VAC circuits and receptacles in the workshop. This change in operating

voltage affects AC charging hardware operation and overall charging power, for one.
•
Ground Faults

Underwriter Laboratory (UL) requirements define ground

fault and residual current detection capabilities for EVSEs.

By design, ICCPDs are extremely sensitive to ground

faults in the supply infrastructure.

The self-test function of typical residential GFCI receptacles

can cause ground faults. GFCI receptacles or circuits are a

common code requirement, especially in residential garages

and damp or wet locations.

A qualified electrician may need to ensure the quality of the

complete electrical system grounding and bonding (metal
