High-voltage system

General information

voltage components and high-voltage ca-

bles.

– Any gases escaping from the high-voltage

battery may be toxic or flammable.

– Do not expose yourself to any fluids escap-

ing from the high-voltage battery; avoid all

contact with these fluids.

Introduction

Applies to: vehicles with plug-in hybrid drive

All work on the high-voltage system must be car-

ried out solely by qualified high-voltage techni-

cians and authorised workshops according to Au-

di's regulations.

– The electrolyte fluid in the high-voltage bat-

tery is corrosive. If the electrolyte fluid

comes into contact with your skin, rinse the

affected area with clean water for at least

15 minutes and then wash with soap. Have

the affected area examined by a doctor.

– In the event of a technical emergency, in-

form the service team that the vehicle is

equipped with a high-voltage battery.

The high-voltage system includes a high-voltage

battery, power electronics, electric motor, a high-

voltage air conditioner compressor, a high-volt-

age heater, charging system, charging socket and

orange high-voltage cables.

The high-voltage battery is located under the lug-

gage compartment floor and does not require

any maintenance to be performed by you.

CAUTION

The high-voltage system can be damaged if

the underside of your vehicle makes heavy

contact with the ground. Drive to a qualified

workshop without delay and have the vehicle

checked.

WARNING

The voltage of the high-voltage system is le-

thal! Touching damaged high-voltage compo-

nents could cause you to be fatally electrocu-

ted. A warning sticker is attached to the dif-

ferent parts of the high-voltage system. This

is intended to warn you of the high voltage.

– Even when the ignition is switched off, po-

tentially lethal voltages still exist in the

high-voltage system.

What to do in hazardous situations

General rules

Hazardous situations may occur if a driver mes-

sage is shown or if you can smell smoke or gas. In

the event of a hazardous situation, you should

behave as follows:

– Do not touch any contacts on the vehicle

charging socket, e.g. when cleaning the

charging unit. If you wish to clean the charg-

ing unit, only use a dry cloth and no other

tools such as a screwdriver or brush.

– Do not inhale the fumes.

– Ensure that you and all other occupants have

left the danger area and remain in an area

which is safe from all traffic (e.g. behind a road-

side crash barrier).

– Never perform work on the orange-coloured

high-voltage cables or the other high-volt-

age components yourself. Work on the high-

voltage system may only be performed by

authorised workshops that have been ap-

proved for this type of work.

– Inform the emergency services.

– Do not attempt to extinguish any fires yourself.

– Do not try to move the vehicle.

Driver messages

– The orange-coloured high-voltage cables

must never be damaged, modified, removed

or disconnected from the high-voltage sys-

tem.

tery. You should behave as follows:

Proper use of the high-voltage battery

Applies to: vehicles with plug-in hybrid drive

A plug-in hybrid vehicle is equipped with an elec-

tric and a conventional drive system. The electric

drive system is powered by a high-voltage battery

(also known as a hybrid battery or traction bat-

tery) and supports the combustion engine ac-

cording to the situation. The way in which it is

used has an effect on the service life of the high-

voltage battery. Please therefore observe the fol-

lowing information on careful use of the high-

voltage battery:

– Stop the vehicle without delay, paying atten-

tion to the traffic situation.

– You should use a safe place in the open, keep-

ing a safe distance from buildings, other

vehicles, overhanging roofs, carports or other

structures.

– Switch the hazard warning lights on, if possi-

ble.

– Apply the parking brake.

– Switch off the ignition.

►

Ensure a good balance between use of the elec-

– To assist the emergency services, leave the ve-

hicle key in a visible location in the vehicle, e.g.

in the centre console.

tric drive system and use of the conventional

drive system. If only the electric drive system is

used to power the vehicle for extended periods,

the high-voltage battery will wear more quickly.

– Get out of the vehicle immediately and make

sure that no other persons or animals remain in

the vehicle.

►

Avoid discharging the high-voltage battery

quickly as a result of repeated abrupt accelera-

tion when the vehicle is being powered solely

by the electric motor or when using the boost

function.

Do not use your vehicle to jump-start another

vehicle. This could cause serious damage to

your vehicle's electrical system.

– Ensure that you and all other occupants have

left the danger area and remain in an area

which is safe from all traffic (e.g. behind a road-

side crash barrier).

►

– Continue to follow the general rules

ðpage 139.

The acoustic warning inside the vehicle can only

be deactivated by a qualified workshop.

Protective functions in the event of a fault

In the event of a serious fault in the high-voltage

battery, the vehicle may trigger additional pro-

tective functions (e.g. the hazard warning lights

may be switched on or the horn may sound after

the ignition is switched off).

WARNING

If there is a risk of fire in high-voltage battery

cells, toxic gases may escape or high-voltage

components may be live. Risk of severe inju-

ries, burns or a fatal electric shock.

– Get out of the vehicle and evacuate all per-

sons and animals.

– Ensure that you and all other occupants

have left the danger area.

High-voltage system

Charging the high-voltage battery

Introduction

Applies to: vehicles with plug-in hybrid drive

The following options are available for charging

the high-voltage battery:

Charging method

Charging cable

Charging at a domestic or industrial AC power

outlet

Audi e-tron compact charging system ðpage 150

Charging at a public charging station (with AC

power)

Factory-supplied charging cable ðpage 149 or

charging cable at charging station

When using alternating current to charge the

high-voltage battery, Audi recommends connect-

ing to an industrial power outlet, charging sta-

tion or wallbox. The efficiency will be higher and

the charging time much lower compared with

charging at a domestic power outlet.

– Ignition switched on/off.

Important safety notes

Applies to: vehicles with plug-in hybrid drive

WARNING

You should only charge the vehicle at a domestic

power outlet with the Audi e-tron compact charg-

ing system if an industrial AC power outlet or a

public AC charging station is not available.

Improper battery charging, (e.g. failure to ob-

serve generally applicable safety precautions,

the use of unsuitable or damaged outlets and

charging cables, or charging at unsuitable

electrical installations) can result in short-cir-

cuits, electric shocks, explosions, fire and seri-

ous burns – risk of fatal injury!

The driving range of a high-voltage battery di-

minishes over time as the battery ages. The age-

ing process can be accelerated and the available

range reduced even more if the high-voltage bat-

tery is frequently charged to its maximum capaci-

ty.

– Do not charge the vehicle at a power outlet

or electrical installation if it shows signs of

damage or improper installation.

– Never use charging equipment which is visi-

bly damaged and/or dirty. Always check the

charging equipment for damage before use.

– Never make modifications or repairs to elec-

trical components and in particular to the

high-voltage system.

Charging time

The amount of time required to charge the vehi-

cle can vary depending on the following:

– Type of power outlet used (domestic or indus-

trial).

– Never charge the vehicle in potentially ex-

plosive atmospheres. The components of

the charging equipment can produce sparks

and ignite flammable or explosive vapours.

To reduce the risk of explosions, especially

in garages, please ensure that the operating

unit of the Audi e-tron charging system is at

least 50 cm above the ground during charg-

ing.

– The country’s grid voltage, current rating and

number of phases available.

– Domestic connection.

– Charging capacity setting on Audi charging sys-

tem operating unit.

– Fluctuations in mains supply.

– Ambient temperature surrounding the vehicle.

– Temperature of high-voltage battery and Audi

charging system operating unit.

– Air conditioner settings for interior tempera-

ture.

– Never use an extension cable, a cable reel, a

multiple outlet strip or adapter (e.g. a travel

adapter or time switch) with the charging

equipment.



– Electrical capacity of charging connector.

141

High-voltage system

– Do not touch the contacts on the vehicle

charging socket and charging equipment.

– Do not insert any objects in the vehicle

– Always protect power outlets and plug con-

nections against water, humidity and other

fluids.

battery is charged via the domestic/industri-

al power outlet. Audi recommends that the

electrical installations used for charging be

checked regularly by an electrician.

– Whenever possible, disconnect Audi charg-

ing systems from the charging infrastruc-

ture during thunderstorms.

– Never immerse Audi charging systems or

the connectors in water.

– Use only the factory-supplied charging

equipment provided with your vehicle or the

charging cable at the charging station.

– Only clean Audi charging systems when the

operating unit is fully disconnected from the

power grid and from the vehicle. Use a dry

cloth for cleaning.

WARNING

Applies to: Audi charging systems

– Audi charging systems are only suitable for

use with Audi vehicles. These charging sys-

tems are not approved for use with vehicles

manufactured by other companies.

Improperly installed power sockets can result

in electric shock or fire when the high-voltage

battery is charged via the vehicle charging

socket.

– The home power outlet for Audi charging

systems must be installed and commis-

sioned by a qualified electrician. The electri-

cian is responsible for full compliance with

existing regulations and standards.

CAUTION

– The high-voltage battery can be damaged if

it is allowed to discharge completely.

Charge the high-voltage battery within

2 months when the remaining electrical

range shows 0 km. Charge the high-voltage

battery immediately if the remaining elec-

trical range shows 0 km and the vehicle will

not be used for an indeterminate period.

Even if the vehicle is not used, the charge

level of the high-voltage battery will drop

naturally over time. Before parking the vehi-

cle, charge the high-voltage battery to

around 80 % (penultimate charging bar) to

avoid deep discharge when the vehicle is out

of service for a long time (over one year).

– Please ensure that you always carry suitable

charging equipment for the country in

which you are travelling. For more informa-

tion, contact a qualified workshop.

– Make sure that the domestic power outlet is

earthed and protected from water.

– If Audi charging systems do not operate as

described in the operating instructions, they

must not be used. Please contact a qualified

workshop.

– Audi charging systems are designed for use

in private and semi-public areas (e.g. on pri-

vate land or company car parks). In some

countries (e.g. Italy and New Zealand),

mode 2 charging (which includes charging

with the Audi charging system) is prohibited

in public areas. In some countries and re-

gions (e.g. Abu Dhabi, Israel, Singapore and

India), it is prohibited to charge vehicles at

domestic power outlets. For more informa-

tion, contact a qualified workshop.

Note

– Audi charging systems should be used in

properly earthed power grids. Operation in

unearthed networks (e.g. IT networks) is on-

ly possible using Audi charging systems with

deactivated protective earth conductor

monitoring ðpage 151.

– Only charging stations which meet the fol-

lowing standards (minimum requirement)

and the standards applicable in your coun-

try can be used to charge the vehicle:

– GB/T 18487.1 and GB/T 20234 (China)

– IEC 61851 and IEC 62196 (Europe)

– SAE J1772 (North America, Japan)

– The electrical installation can be loaded to

maximum capacity when the high-voltage

Important safety notes.

Limiting the charging capacity

You can limit the charging capacity and therefore

also the charging current used. You can specify

whether you want to charge at reduced (50 %) or

full (100 %) capacity. Full charging capacity

(100 %) achieves the shortest charging time; it

should only be selected if the electrical installa-

tion has been checked by a qualified electrician.

Reduced charging capacity (50 %) can reduce the

load on the electrical installation and prevent it

from overheating or becoming overloaded, for

Depending on the charging system, note the fol-

lowing characteristics with regard to limiting the

charging capacity:

conductor monitoring

– When using a domestic power outlet, the most

recent setting is always stored and is called up

again for the next charging cycle.

Please read the safety information on PE conduc-

tor monitoring ð

.

If the PE conductor monitoring has interrupted

the charging cycle and the LED on the operating

unit 6 ðFig. 106 and the two status LEDs 

and  are lit in red, you should deactivate PE

conductor monitoring as follows:

– Applies to charging system with 3.6 kW,

7.2 kW or 11 kW: When using an industrial

power outlet, the most recent setting is always

called up.

– Applies to charging system with 9.6 kW: When

using an industrial power outlet, the charging

capacity limitation is reset to 50 % when there

is no longer any mains supply to the charging

system (e.g. due to the mains plug being un-

plugged).

– To deactivate PE conductor monitoring, press

buttons  6 and  8 ðFig. 106 simultane-

ously for six seconds. The status LED  will

flash in white while you are doing so. Release

the buttons again for one second.

– Press both buttons  and  again for six sec-

onds. Deactivation will take place automatically

after a brief interval. The LED on the operating

unit 6 will pulsate in green and the two status

LEDs  and  will light up in yellow.

Before each charging cycle, you should check

whether the last charging capacity setting is de-

sired for the current charging cycle.

– To adjust the charging capacity limitation,

press the  button 6 ðFig. 106 for at least

two seconds.

– To activate PE conductor monitoring, press and

hold buttons  and  until the status LEDs 

WARNING

The use of the Audi e-tron compact charging

system without PE conductor monitoring acti-

vated can cause short-circuits, electric shocks,

explosions and fires or burns. The Audi e-tron

compact charging system should be used in

earthed power grids. Deactivate PE conductor

monitoring only in unearthed networks (e.g.

IT networks). Activate PE conductor monitor-

ing in earthed power networks.

Note

Fig. 107 Operating unit: Releasing/securing the cable

When the power supply is connected or re-

stored, the operating unit performs a self-

test routine. All the LEDs will light up in green

for two seconds if the self-test routine is suc-

cessful.

Requirements:

►

The high-voltage battery must have finished

charging ðpage 144.

►

The vehicle charging connector must be un-

plugged from the vehicle charging socket.

►

The mains plug must be removed from the

power outlet.

Releasing the cable

►

Lift the lever 1 all the way up.

►

Pull the connector 2 out until the first point of

resistance.

►

tem

– Always remove the mains cable from the

power outlet before changing a cable.

– Change the cable in dry environments only.

– The Audi charging system must always be

used complete with the mains cable, operat-

ing unit and vehicle cable. In some coun-

tries, the total length of the mains cable,

operating unit and vehicle cable are limited,

e.g. to 7.5 m in Israel. Audi recommends

that you only use cables approved by Audi.

Hooking in the Audi charging system

►

Hook the operating unit into the retainers on

the clip wall mount, first at the bottom, then at

the top.

►

Press the operating unit back in the direction of

the arrow ðFig. 108 so that it engages.

►

Wind the length of cable you do not need

around the charging connector mounting

when you are not charging the high-voltage

battery.

►

Plug the mains cable into the power outlet 2 .

After charging, you can hook the vehicle charg-

ing connector into the charging connector

mounting 1 .

Note

– The mains cable with mains plug for indus-

trial power outlets and the operating unit of

the Audi charging system are specially

matched. Changing the mains cable to a dif-

ferent type of connector can reduce the

charging capacity of the entire system. Fac-

tors influencing the charging capacity here

are the limited power transmission (electri-

cal capacity) per phase and the number of

phases available.

Unlocking/locking the Audi charging system

►

Use the enclosed key to unlock/lock the Audi

charging system as required (locked: 4 , un-

locked: 5 ).

Removing the Audi charging system

►

Unplug the mains cable connector from the

power outlet 2 .

Unwind the cable from the vehicle charging

connector 1 .

To release the operating unit from the holder,

press the locking mechanism 3 upwards.

– To reduce the risk of the charging system

and cable being stolen, you can secure the

lever on the charging cable with a screw.

Your Audi dealer will be able to provide you

with more detailed information.
