background, and Service Information
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

monitors. Diagnostic information, event logs, and diagnostic trouble codes (DTCs) can then be accessed through

the PMCC Web Application (accessible through local IP query or the PMCC Hotspot) in addition to using the PIWIS

Tester and diagnostic adapters provided as Porsche Special Tools.

Diagnostic Troubleshooting Tips

•

AC charging concerns should be checked with customer-supplied charging hardware (supply cable, charge 		
control unit, 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.
The charge control unit is 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
underground water pipes, in-ground support structures, or

Figure 2

				concrete-encased electrodes, for example)
