Product information
The Porsche Home Energy Manager works in
combination with the Porsche charger as an energy
management system.
The Porsche Home Energy Manager measures and
individually assesses the available amount of energy
and the electricity consumption. The Energy Manager
communicates with the Porsche charger via an
interface, and lets it know how much energy can be
made available to the hybrid or electric vehicle for
charging the vehicle battery.
The electrician configures the Energy Manager for you
via a web application, and sets all the necessary
values there. This way, your existing electrical
installation is protected against "blackout" and your
vehicle can be charged at low cost. However, this
feature is only available if different electricity
rates/prices and/or an existing photovoltaic system are
used.
When vehicle charging begins, the so-called
negotiation phase starts and the Energy Manager
generates price and output tables in accordance with
the current ISO/IEC 15118 standard.
Transmission between the Energy Manager and the
Porsche Mobile Charger Connect takes place via
Ethernet, PLC network or WiFi using the EEBus
protocol.
During charging, the Energy Manager updates the
maximum available charging current in real time based
on the latest data.
Proper use
The Porsche Home Energy Manager is primarily used
to safeguard the electricity supply (blackout protection)
by preventing the building's main fuse from tripping.
The following count as improper use:
 Carrying out your own modifications or additions
to the Porsche Home Energy Manager.
 All other use of the Porsche Home Energy
Manager not described in these instructions.
