2021 AUDI E-TRON battery capacity

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 () 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 used may be a maximum of 98 feet (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

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.

fire, and severe burns can result from charg-

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.

High-voltage system


— Only change cables in a dry environment.
— The Audi charging system may only be used
as a complete unit consisting of the power
cables, the control unit, and the vehicle ca-
ble. Depending on the country, the total
length of the power cable, control panel and
vehicle cable may be restricted, for example
to 24.6 feet (7.5 m) in the USA. Audi recom-
mends using only cables approved by Audi.
@) Tips
The power cable with the power connector for
industrial sockets and the Audi charging sys-
tem control unit are designed to work togeth-
er. Changing the power cable to another con-
nector type may reduce the available charging
power of the entire system. Limitations on
the ability to transfer power (current capacity)
depending on the phase and the number of
available phases may affect the available
charging power.
Wall mo clip
Applies to: vehicles with wall mount clip



RAZ-0638,



Fig. 89 Wall mount clip: securing the Audi charging system
Securing the Audi charging system
> First insert the control unit in the bottom tabs
on the wall mount clip and then into the upper
tabs.
> Push the control unit in the direction of the ar-
row toward the rear > fig. 89 and let it lock into
place.
> Wrap the excess length of cable around the
charging connector mount @ when you are not
charging the high-voltage battery.
> Plug the power cable into the socket (2).
> After charging, you can hook the vehicle charg-
ing connector to the charging connector mount
©.
Locking and unlocking the Audi charging
system
> You can lock or unlock the Audi charging sys-
tem using the key provided by turning it to the
lock position @) or the unlock position 6).
Removing the Audi charging system
> Remove the power cable connector from the
socket (2).
> Unwind the cable from the charging connector
mount (@).
> To loosen the control unit from the bracket,
push the locking mechanism @) upward.

ZX WARNING
Observe the safety precautions in the assem-

bly instructions for the wall mount clip.

Checking and Filling

@ For the sake of the environment
© ¥ Lead-acid batteries must be disposed of
using methods that will not harm the environ-
ment. Do not dispose of them in household
trash. They contain harmful substances, such
as sulfuric acid and lead, and also recyclable
raw materials. Contact an authorized Audi
dealer or authorized Audi Service Facility for
more information.

Charging the 12 Volt vehicle battery
The vehicle cannot be operated when the 12 Volt
vehicle battery is drained. The vehicle battery
must not be charged under any circumstances.
Contact an authorized Audi dealer or authorized
Audi Service Facility.
@) Note
The charging of the vehicle battery requires
specialized knowledge and technology.
— The vehicle battery may only be charged by
an authorized Audi dealer or authorized
Audi Service Facility. Otherwise, the elec-
tronic systems in the vehicle may be severe-
ly damaged.
— The jump start pins in the motor compart-
ment are designed specifically for qualified
technicians.
Windshield washer
system

B4M-0135|


Fig. 154 Motor compartment: washer fluid reservoir cap
Observe the safety precautions > page 233, Gen-
eral information.
The windshield washer reservoir © contains the
cleaning solution for the windshield/rear window
and the headlight washer system* > fig. 154,
=> page 235. The reservoir capacity can be found
in > page 291.
To reduce the risk of lime scale deposits on the
spray nozzles, use clean water with low amounts
of calcium. Always add window cleaner to the wa-
ter. When the outside temperatures are cold, an
anti-freezing agent should be added to the water
so that it does not freeze.
Messages
3 Please add washer fluid
Fill the washer fluid for the windshield washer
system and the headlight washer system* when
the ignition is switched off.
@) Note
— The concentration of anti-freezing agent
must be adjusted to the vehicle operating
conditions and the climate. A concentration
that is too high can lead to vehicle damage.
— Never add radiator anti-freeze or other addi-
tives to the washer fluid.
— Do not use a glass cleaner that contains
paint solvents, because this could damage
the paint.
Service interval display
The service interval display detects when your ve-
hicle is due for service.
The service interval display works in two stages:
— Inspection reminder: after driving a certain
distance, a message appears in the instrument
cluster display each time the ignition is switch-
ed on or off. The remaining distance or time is
displayed briefly.
— Inspection due: if your vehicle has reached an
inspection interval, the message Inspection
due! appears briefly after the ignition is switch-
ed on and off.
Checking service intervals
You can check the remaining distance or time un-
til the next service.
