Background information on
the Suspend Charging mode
–
Section 14a of the Energiewirtschaftsgesetz (German energy law) species the possibility
for consumers to use electricity at reduced standing charges if it complies with certain
conditions. The option only applies to customers who have a controllable device containing
an independent measuring module (for instance an EV charging station) connected to their
domestic energy connection.
The grid operator’s energy meter is equipped with a potential free contact. By connecting
the customer’s device to the grid operator’s energy meter via data cables, the grid operator
can send a signal to the charging station to temporarily abort the energy demand to
avoid an overload of the grid. During the shut-o time the customer will not be able to
charge, but will still be able to use other household equipment. Temporarily disabling the
possibility to charge is called the Suspend Charging mode.
This document describes the installation and conguration of the Suspend Charging mode
functionality.

2.1 Functionality
Alfen has developed a solution to suspend a running
charging session on request of the grid operator.
Suspending the charging session is done in a controlled
way, according to the Mode 3 protocol.
The grid operators energy meter is equipped with a
potential free contact. The grid operator controls the
energymeterandcaneitheropenorclosethecontact(S1).
When the contact is closed, the charging station can charge
at full power. When the contact is open, the charging power
isreducedto0W.
The charging station makes sure a running transaction is
suspended according to the Mode 3 protocol. The screen
onthechargingstationwillshowamessagefortheuser:
‘Charging session halted by energy supplier’. In case the
charging station is not equipped with a screen, the blue
led will blink to indicate the power supply is halted by the
energysupplier.Duringtheshut-otimeitispossibleto
start a new charging session; the session, however, will be
paused immediately. As soon as the potential free contact
(S1)closesagain,thechargingstationwillcontinuethe
suspended charging session.

2. FUNCTIONALITY
DANGER!
In this document the contact is considered to be closed
when charging is allowed. In practice it is possible that the
contact is open when charging is allowed. The installer is
responsible to assess the situation and act accordingly.
NOTICE!
This functionality is developed for all Eve (Single and
Double)chargingstationsandavailablefromsoftware
version 3.4.2 and higher.
