Overview of Overload Protection Setup
In order to use the Overload Protection,
CT coils need to be installed at the house’s
critical installation point. This might be at
the house’s main fuse or any other sub-
distribution where the residential load and
the charging power might exceed the local
restrictions. These CT coils need to be wired
to the Audi Wallbox. Since usually the critical
installation point and the Audi Wallbox are
located some distance apart, a data cable
in needed to properly establish this wired
connection.
For the three-phase variant of the Audi
Wallbox also three CT coils can be used, i.e.
one CT coil per installation phase. To ensure a
proper monitoring of the critical installation
point, all these CT coils should be located at
the same place of the electric installation.
The Audi Wallbox adapts its offered charging
power for all its phases, based on the
installation phase with the highest load, and
thus avoid any load imbalance due to the
charging of the vehicle.
The illustration provided below is showing a
qualitative example of a house with the CT
coils being installed right at the main fuse.
With this setup the CT coils will detect the
full residential load of all power consuming
devices in the house.
Installation of Overload
Protection
This section is to state the material needed
for a proper installation of the Overload
Protection and how to perform the
respective installation steps.
If the Audi Wallbox is being used with
for Overload Protection, it will only adapt
the offered charging power based on the
measurements of the CT coils with respect
to the configured maximum current
allowed at that point of installation.
When the residential load is low enough,
the Audi Wallbox will then offer its full
charging power to the vehicle, i.e. 32 A
for single-phase and 16 A for three-phase
version.
It is not possible to use the Audi
Wallbox's Overload Protection and have
the Audi Wallbox itself limited to less
than its full charging power. This needs
to be considered designing the electric
installation, i.e. choosing breaker and RCD
sizes.
The needed material listed in this
chapter is not provided with any version
of the Audi Wallbox. Neither can it be
ordered from Audi at the moment.
Please ask your certified electrician for an
offer when planning the installation of the
Audi Wallbox.
The Overload Protection is a comfort
feature of the Audi Wallbox. It is not
claiming to fulfil any country-specific
standards or local requirements. The
Overload Protection is neither a substitute
for security devices, such as breakers,
to protect electrical installations from
damage due to excess currents.
› A certified electrician must always check
and decide about the eligibility of the
intended use.
