Information:
Porsche Mobile Charger with NEMA industrial plug
Porsche Mobile Charger Plus with NEMA industrial plug
Porsche Mobile Charger Connect with NEMA industrial plug
Campaign Summary
Actions required:
1. Retrofit warning sticker on the charging electronics and attach photo of mobile charger to job line
2. Limit charging current at the charging electronics initially to 50% in conjunction with the industrial
supply cable
3. Give an Owner's Manual Supplement to the customer
Note:This Workshop Campaign is focused on the industrial supply cable (208-250V). The
charging electronics, the Mobile Charger Connect, for example, retains the maximum charging current
separately for domestic (120V) and industrial supply cables. Therefore, this workshop campaign
must be performed with the industrial supply cable connected to the charging electronics.
Workshop Campaign WMP2 is designed to reiterate and reinforce the importance of a high-quality electrical installation. It includes the following actions at the Porsche dealership service center:
•
•
•
A decal with warning symbols is applied to the face of the charger
The charger is set to 50% as a 1-time operation
An Owner’s Manual supplement describing the importance of a high quality (industrial) outlet and
proper wiring is provided to the customer
The customer must then use the Owner’s Manual supplement and decide if their receptacle and electrical
installation is capable of charging at 100% for prolonged periods. Turning the power back to 100% is not
advised if the customer has experienced overheating of, or damage to, the electrical receptacle.

NOTE: A software bug for the Porsche Mobile Charger Connect (PMCC) can cause the charger to lose
the desired "last mode" setting following a power cycle (unplugging) or a deep sleep (Sleep Mode: On).
This software bug is unrelated to Workshop Campaign WMP2, but the timing and contents of WMP2 and
the software bug have led to confusion. Refer to the separate Technical Information concerning PMCC
software bugs.

General NEMA (250V) Receptacle Home Installation Precautions
Porsche recommends home owners only install industrial quality electrical NEMA receptacles and have
the installation performed by qualified electricians in accordance with the National Electrical Code or
applicable local equivalents.
For example, the following receptacles are recommended for their industrial quality and ability to handle
high current with minimal electrical resistance for long periods of time:
•
•
Hubbell HBL9450A = NEMA 14-50 Receptacle (4-wire)
Hubbell HBL9367 = NEMA 6-50 Receptacle (3-wire)
A 50-amp branch circuit should use minimum 6 AWG, 90°C-rated copper wire for conductors supplying
level 2 Porsche charging hardware plugged with a NEMA 14-50 or 6-50 supply cable. Receptacle
terminal screws must be tightened to manufacturer specifications. The use of ferrules on the supply
conductor wiring is recommended to further safeguard the circuit connection at the receptacle.
Caution
If the electrical receptacles/outlets are not of sufficient quality, higher temperatures can
occur in the receptacle when charging the vehicle using the supplied charging hardware (e.g.
Porsche Mobile Charger). This can result in thermal damage to the receptacle and associated
wiring. Low quality receptacle use or improper installation are not an indication of a defect in
the vehicle or Porsche charging hardware.
General Precautions on (125V) Supply Cable Use
The “domestic” (125V) supply cable is provided for emergency use only, and should not be used by
customers for daily home charging. Please discuss installation and use of a suitable 250V circuit with
all customers.

Caution
The surface of the charger and associated equipment can become very hot under normal use. This is
normal and not an indication of a defect in the charger. Observe the operating instructions provided with
the charger, particularly the warnings and safety instructions.
When used, it is recommended to limit 125V charging to a maximum of approximately 12 hours. Charge
only to a minimum needed get to a nearest High-Power Charger (HPC) or DC Charger for recharging.
