Data privacy information

To ensure that your Porsche charging equipment is communicating correctly and is always up-to-date, Porsche collects and processes the following encrypted device-specific data from the charging equipment at regular intervals: device ID, brand, generation, device type and software version.
If you would also like to have the option of using other Porsche Connect services for the charging equipment, you must pair your charging equipment to your Porsche ID account, which is available from the Porsche Connect distributor in selected markets. While using Porsche Connect services, Porsche collects and processes the following personal details and other device- specific data in order to provide and render these services: customer ID, statistics, device status, connection status and time stamp of when communication was last established. You will find further information about the general terms and conditions of business and the data privacy policy at www.porsche.com/connect-store. Regular data transfer from your charging equipment can incur additional costs with your Internet service provider. Your data stored at Porsche can be permanently deleted using My Porsche. Due to technical or legal restrictions, some of the Porsche Connect services on the Porsche charging equipment are not available in all countries.

Product information

In combination with Porsche charging equipment, the Home Energy Manager functions as an energy management system.
The energy manager measures and individually assesses the available power and current consumption. The energy manager communicates with the Porsche charging equipment via an interface.
The energy manager communicates the energy costs to the charging equipment and how much power may be made available to the vehicle for charging.
During charging, the energy manager updates the maximum available charging current in real time based on the latest data.
The qualified electrician sets the energy manager up for you via a Web Application, and sets all the necessary values there. This way, your existing electrical installation is protected against overload and your vehicle can be charged at low cost. Cost-optimized charging is only available if different electricity rates/ prices and/or an existing photovoltaic system are used.
Transmission between the energy manager and the charger takes place via Ethernet, PLC (Powerline Communication) network or WiFi using the EEBus protocol.
It is recommended to connect the energy manager to the home network via Ethernet. If you do not have

PLC modem in your home network, the energy manager must be configured as a PLC DHCP server.
Observe the Home Energy Manager installation instructions.
Information on setting up and using the Home Energy Manager can be found at: https://tinyurl.com/porsche-e-help
If you require a different language, please select the appropriate website for your country.
