High-voltage system
Charging the high-voltage battery
Introduction
Applies to: vehicles with plug-in hybrid drive
The following options are available to charge the
high-voltage battery:
Charging method Charging cable
Charge with household and industrial alternat-
ing current (AC) sockets
Audi e-tron compact charging system > page 131
Charge at public alternating current (AC) charg-
ing stations
Charging station cable
Audi recommends using alternating current (AC)
to charge the high-voltage battery at industrial
sockets, charging stations, or a wallbox. This will
allow you to achieve higher efficiency and a con-
siderably shorter charging time when compared
to charging with a household socket.
Only charge at household sockets with the
Audi e-tron compact charging system under spe-
cial circumstances when it is not possible to
charge at an industrial alternating current (AC)
socket or at a public alternating current (AC)
charging station.
High-voltage batteries age over time, which re-
duces the available range. High-voltage batteries
can also age because of how they are used: fre-
quently charging the high-voltage battery com-
pletely accelerates the aging of the battery and
reduces the available range.
Charging time
The duration of the charging process may vary
based on the following factors:
— Sockets being used (household or industrial
sockets)
— Country-specific system voltage, current
strength and number of available phases
— Household connection
—The value set for the charging power level on
the Audi charging system control unit
— Fluctuations in the system voltage
— The temperature outside the vehicle
— The temperature of the high-voltage battery
and the Audi charging system control unit.
— Settings for the climate control inside the vehi-
cle
— Current capacity of the charging connector
— Whether the ignition is on or off
Important safety precautions
Applies to: vehicles with plug-in hybrid drive
Z\ WARNING
Short circuiting, electric shock, explosions,
fire, and severe burns can result from charg-
ing the battery incorrectly (for example by
disregarding general safety precautions, using
unsuitable or damaged sockets and charging
cables, or charging with unsuitable electrical
equipment) and can lead to serious and fatal
injuries.
— Do not charge using sockets/electrical
equipment that is clearly damaged or instal-
led incorrectly.
— Never use charging equipment that is clearly
damaged and/or dirty. Check the charging
equipment for damage before every use.
— Never modify or repair any electrical compo-
nents, especially the high-voltage system.
— Never charge in areas at risk for explosions.
The components in the charging equipment
can trigger sparks, which can cause flamma-
ble or explosive fumes to ignite. To reduce
the risk of explosions, especially in garages,
make sure the Audi e-tron charging system
control unit is at least 19 inches (50 cm)
above the floor when charging.
— Never use the charging equipment with an
extension cord, a cable reel, a power strip,
123

High-voltage system
or an adapter, for example, a travel adapter
or timer.
— Do not touch the contacts on the vehicle
charging port or charging equipment.
— Do not insert any objects in the vehicle
charging port or in the charging equipment.
— Always protect the sockets and connections
from water, moisture and other fluids.
— Only use the charging equipment provided
by the factory or the charging station cable.
ZA\ WARNING
Applies to: Audi charging systems
Sockets that are installed incorrectly can
cause electric shock or fire when charging the
high-voltage battery using the vehicle charg-
ing connection.
— Read all information and safety precautions
for Audi charging systems before using
them.
— Monitor the Audi charging system if it is be-
ing used near children.
— Installation and setup of the household con-
nection for Audi charging systems may only
be performed by a qualified electrician. The
qualified electrician is thereby responsible
for adhering to applicable standards and
regulations.
— Make sure that the household socket is
grounded and shielded from water.
— If Audi charging systems do not function ac-
cording to the specifications in the operat-
ing manual, they must not be used. Contact
an authorized Audi dealer or authorized
Audi Service Facility.
— Audi charging systems are intended for use
in private and semi-private areas (for exam-
ple, private property and company parking
lots). Depending on the country where the
vehicle is operated, charging with a mode 2
charging cable (meaning charging with the
Audi charging system) may be prohibited in
public areas. Contact an authorized Audi
dealer or authorized Audi Service Facility for
more information.
— Operate the Audi charging systems in power
networks that are properly grounded. It can-
not be used with non-grounded power net-
works (such as IT networks).
— When charging the high-voltage battery us-
ing household/industrial sockets, the elec-
trical installation can be used at full capaci-
ty. Having a qualified electrician regularly in-
spect the electrical installations that are
used for charging is recommended.
- If possible, disconnect Audi charging sys-
tems from the power network during a
thunderstorm.
— Never submerge the Audi charging systems
or the connectors in water.
— Audi charging systems must only be cleaned
when the control unit is completely discon-
nected from the power supply and from the
vehicle. Use a dry towel to clean.
— Audi charging systems are only intended for
use on Audi vehicles and vehicles within the
Volkswagen Group. Using the devices on
vehicles made by another manufacturer is
not authorized.

@) Note
— Severely draining the high-voltage battery
can damage it. Once a O mi (0 km) electric
range is displayed, charge the high-voltage
battery within two months. If the stationary
time is unknown with the electric range at 0
mi (0 km), charge the high-voltage battery
immediately. Even if the vehicle is not used,
the high-voltage battery charge level will
naturally reduce over time. To avoid a total
battery drain during long periods without
use (more than one year), charge the high-
voltage battery to the highest level possible
before discontinuing driving it.
— Make sure that you always use the correct
charging equipment for the country in
which it is being used. Contact an author-
ized Audi dealer or authorized Audi Service
Facility for more information.
