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 with the Audi e-tron compact charg-
ing system using household sockets in special cir-
cumstances, when it is not possible to charge
108
with an industrial alternating current (AC) socket
or with a public alternating current (AC) or direct
current (DC) 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. >

High-voltage system

Charging at household and industrial sockets
or at public charging stations with
alternating current (AC)
The vehicle's high-voltage battery can be charged
with alternating current (AC) via the charging
port G) on the driver's side. Depending on the ve-
hicle equipment, there may be a second charging
port © on the front passenger's side. Both
charging ports have the same charging power.
You can use whichever charging port is more con-
venient for your charging setup. When using one
charging port, the opposite charging port is
locked.
Quick charging at public direct current (DC)
charging stations
The vehicle’s high-voltage battery can be charged
at a direct current (DC) charging station via the
charging port on the driver's side (S). There is a
significant decrease in charging time. The charg-
ing cable being used may be a maximum of 30 m.
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
ZA 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,
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.
— Never charge with both vehicle charging
ports at the same time.
— Only use the charging equipment provided
by the factory or the charging station cable.
