11. Change tariff settings
Depending on the tariff, information about possible
time differences in the electricity prices can be pro-
vided here.
e
Select whether the tariff changes within a given
period.
�� Additional information can be provided depend-
ing on the selected setting.
Option Explanation
Static tariff The electricity price remains
unchanged over time.
e
Price per kWh: Enter the
agreed electricity price
per kilowatt hour.
Variable tariff The electricity price is subject
to time differences.
e
Select the corresponding
variance (seasonal, week-
days or during the day)
with Yes and define the
time intervals and their
electricity prices per kilo-
watt hour.
e
If necessary, create and
set additional intervals.
e

12. Optimized charging
Overload protection
The energy manager is informed about current via
existing current converters and thus protects the
fuses of your domestic installation from overloading.
Current converters located on the house connection
only protect the main fuses. For this reason, addi-
tional current converters (not included in the scope
of supply) are recommended on the lines of the sub-
distributions that are used for EEBus devices, e.g.
chargers. Overload protection intervenes if the rated
current of a fuse is exceeded. The charging current is
throttled in this case. If the charge current falls below
the minimum value (vehicle-specific), the charging
process is aborted. If several chargers are used at the
place of use, it is recommended that the charging
processes be coordinated by the energy manager.
The power distribution principle of the energy man-
ager offers the following options.
Option Explanation
Balanced The existing charging
power is evenly distributed
to all vehicles.
Chronologically The charging equipment
that first starts a charging
process is prioritized in the
energy distribution.
Individually The first EEBus device in
the list is prioritized for
power distribution.
Option Explanation
e
To change the se-
quence, drag the devi-
ces to the desired po-
sition.
Information
If several charging sessions are carried out simulta-
neously, the energy is distributed according to the
option selected here.
Information
Update: Phase-specific throttling
When the plug-and-charge function is activated,
Porsche vehicles supplied with energy managers can
perform phase-specific throttling of the charging
current. The limit value of the minimum charging
power is then significantly lower and the charging
process may no longer be interrupted by throttling.
Self-consumption optimization
The function is deactivated by default.
e
Activate the function via the switch.
When the function is activated, the vehicle can de-
cide whether it will continue charging with the en-
ergy offered from the photovoltaic system after the
minimum charge has been reached. Until the mini-
mum charge (indication as a percentage of battery
capacity) is reached, the vehicle is charged with
maximum possible power (if necessary, limited by
the overload protection provided). The vehicle then
charges in an optimized manner, i.e. it may only
charges if there is power available from the photo-
voltaic system that would otherwise be fed into the
power grid as a surplus.
