Revised to only show relevant information for DC
Charging

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

Technical Background
DC Charging complaints occur due to a wide range of issues. Root causes span from misunderstanding functions
or user configurations to both internal and external hardware or software issues. Additional functionality (for
example, Plug and Charge via ISO-15118) increases potential for breakage and complaints. For those reasons,
extremely detailed documentation of customer complaints is necessary to assist duplication and diagnosis.

Service Information
Customers are encouraged to contact the Customer Contact Center directly via 1-800-PORSCHE for first-level,
second-level, and immediate support of charging at home or on the road. The customer contact center is prepared
to field customer requests and further clear important details in the event additional support discussions are
necessary with other suppliers (for example, Electrify America customer care or Agero roadside service support).
Customers are also able to contact charge point operators (CPOs) directly to request assistance starting a charging
session. Electrify America Customer Assistance is available by calling 1-833-632-2778.
Porsche Center personnel may contact charging.support@porsche.us for assistance with the following
equipment or systems:
•
24 kW Delta DC charger
•
50 kW BTC Power DC charger
•
Porsche Charge Boxes
•
Porsche Charging Pedestals
•
Charge Point Management
NOTE: Porsche Centers with a “Turnkey” installation contract with ABM for AC and DC Charging installations

should contact ABM directly for assistance.

ABM Contact Info: Phillip Volk ([email protected]), Brian Arvidson ([email protected]),
Numerous information sources and documents are currently available to Porsche Centers.

•
SoliD (Solution with integrated Diagnosis): a PPN Online System available to Porsche Center personnel.

It houses nearly all charging-relevant documents in addition to those found in PPN and PCSS.

Contact your PPN Administrator if you need to request access to SoliD
•
Installation and Operating Manuals are provided with charging hardware, are available via SoliD, and are
available via www.Porsche.com.
NOTE: separate operating manuals may exist for both Home User and Customer Service

(For example, Web Application Home User (MCC_HU 01-A) and Web Application Customer Service (MCC_
CS 01-A))
•
Service Information Technik (SIT) books are a valuable source of information for service personnel. At the

time of publication, separate SIT books exist for the initial model launch (2020 Taycan Turbo/Turbo S),

2020 Taycan 4S, and the 2021 Taycan.
•
PPN Portal --> AfterSales --> E-Performance contains detailed information regarding all manner of

charging in addition to processes, policies, and procedures
•
The Porsche.com e-performance page provides customer-friendly Video Tutorials, Manuals, and Software

assistance for AC charging hardware
Tips
•
Customers who experience difficulty starting a charging session should attempt charging with Plug and

Charge Deactivated via the PCM menu Home → Charging → Options[…] (Figure 4).

(Applies to Model Year 2021 and later Taycan, or Model Year 2020 Taycan with a retrofitted 22kW On-Board
Charger)

•
Customer charging complaints should be duplicated in the same manner reported by the customer.
For example, DC charging complaints should be checked with DC charging function tests.
•
Customers not using Plug and Charge may find authenticating the session via smartphone immediately

before plugging in the car to be beneficial (authenticate through the Charging NA App or the new My

Porsche App, for example). This recommendation may differ from the instructions shown on a charging
kiosk display.
•
DC Charging authentication

- Customers are able to authenticate [pay for] charging sessions multiple ways.

- In the event of a DC charging authentication complaint, discuss the process in detail with the customer,

using the attached Questionnaire as a guide.
•
DC Charging performance

- Charging performance, typically indicated by the kW delivered from the charger to the vehicle, depends

upon numerous conditions. The most important conditions visible to the customer are:

1) State of Charge of the HV Battery, and

2) Temperature of the HV Battery

- For example: to achieve the “5% to 80% SOC in 22.5 minutes” charging time stated in sales and marketing

materials, the following conditions are required:

-> A CCS DC fast charging station with > 270kW and > 850V

-> A starting battery temperature range of 86°-95°F (30°-35°C)

- The current calculated HV Battery Temperature can be displayed in the instrument cluster “Information”

screen (Figure 5). Customers may wish to display this value and consider battery temperature for optimal

charging performance.
In the PCM central display, Settings -->
Vehicle Settings --> Displays --> Instrument Cluster --> Customized View

Figure 5

- For physical and chemical reasons, the charging speed decreases as the battery approaches its full
capacity.
- Charging speeds over 80% state of charge are significantly slower and not recommended for daily use.
- For regular fast DC charging usage, Porsche recommends charging at 50kW stations.

- Performance Battery Plus, 93.4 kWh → standard in Taycan Turbo, Turbo S, and all Cross Turismo variants;

optionally available in Taycan (RWD) and Taycan 4S

-> Charges at a maximum rate of approximately 270 kW

-> The “Battery friendly quick charging” function limits DC Charging to an approximate max. 200 kW
- Performance Battery, 79.2 kWh → Standard in Taycan (RWD) and Taycan 4S variants

-> Charges at a maximum rate of approximately 225 kW

-> The “Battery friendly quick charging” function limits DC Charging to an approximate max. 170 KW

- The Maximum Charging Performance chart (Figure 6) provides an indication of how hv battery tempera
ture and SoC conditions at the start of a charging session affect the theoretical maximum charging rate

of the Performance Battery Plus under ideal conditions.

Figure 6

- At temperatures above 81°F, if the HV battery temperature falls below the red box at a given SOC, then

the charging rate may be limited to the level below the red line – even if the temperature later rises above

it again”

- The attached chart (Figure 7) provides an example of the theoretical maximum charge rate under ideal

conditions (purple line) versus the reduced maximum charge rate with Battery friendly quick charging

activated (mint green line).
