Incorrect handling of the high-voltage battery can cause serious injuries or death. Under no

circumstances remove the lid from the high-voltage battery nor disassemble the high-voltage

battery.

Incorrect handling of the high-voltage battery can cause serious injuries or death. Have

maintenance work on the high-voltage battery performed exclusively by properly qualified and

trained specialist staff . Never make modifications to the high-voltage battery. The opened

high-voltage battery must not come into contact with water or other liquids. Liquids can cause

short-circuits, electric shocks and burns.

DANGER

The vehicle's high-voltage network and the high-voltage battery are dangerous and can cause

burns or other injuries and even lead to a fatal electric shock.

●

You should always assume that the high-voltage battery is fully charged and that all high-

voltage components are live. This can also be the case when the electric drive is switched off

and the ignition is switched off.

●

Never touch high-voltage cables, the high-voltage battery or the poles of the high-voltage

battery, and never touch these with jewellery or other metal objects, in particular if the high-

voltage cable, high-voltage battery or high-voltage battery poles are damaged.

●

Never attempt to carry out any work on the high-voltage network, the high-voltage cables or

the high-voltage battery.

Never open, maintain or repair components or parts of the high-voltage network, and never

disconnect them from the network.

Never damage, change or remove the orange-coloured high-voltage cables or disconnect them

from the high-voltage network.

●

Never open, modify or remove the cover of the high-voltage battery.

Any work on the high-voltage system, or on systems which could be indirectly affected by it,

must only be carried out by properly trained and qualified expert personnel.

●

Work in the vicinity of high-voltage components and high-voltage cables with machining,

shaping and sharp-edged tools or heat sources, for example, welding, soldering, hot air or

thermal adhesives, may only be performed after the vehicle has been de-energised. Only

properly qualified and trained specialist staff may de-energise the vehicle.

●

The Volkswagen standards and guidelines must be adhered to when carrying out any work on

the high-voltage system or the high-voltage battery.

Store the vehicle key in a safe place far enough away from the vehicle to prevent any risk of the

ignition being switched on accidentally.

●

Any gases emitted by or escaping from the high-voltage battery may be toxic or flammable.

Damage to the vehicle or to the high-voltage battery could lead to a leak of toxic gases, either

immediately or at a later time. These emitted gases could also potentially cause a fire. If

damage has been incurred, it is vital to then open the vehicle windows to allow any emitted

gases to disperse. Do not inhale these gases.

●

Never touch any liquids or expose yourself to any gases leaking from the high-voltage battery,

especially if the battery has been damaged.

In the event of a fire, move away from the hazard area and call the fire service. Inform the fire

service that the vehicle in question has an electric drive.

Remember to inform any attending emergency services that the vehicle is fitted with a high-

voltage battery.

WARNING

Unqualified work on the high-voltage system and on high-voltage components can lead to

malfunctions, accidents and injuries.

●

Any work on the high-voltage system, or on systems which could be indirectly affected by it,

must only be carried out by properly trained and qualified expert personnel.

WARNING

An electric vehicle does not generate any operating noise when stationary and produces only low

noise when driving. Other road users, such as pedestrians and children, may therefore have

difficulty hearing or detecting the electric vehicle. This can result in accidents and injuries, for

example when driving in traffic-calmed areas, when manoeuvring the vehicle or when driving in

reverse.

NOTICE

After an accident, or after the underside of the vehicle has struck an obstacle, the high-voltage

battery must be checked by appropriately qualified and trained experts.

Charging the high-voltage battery

Introduction to the topic

Fig. 1 On vehicle floor: location of high-voltage battery.

The electric motor of the vehicle is powered via a high-voltage battery located on the underbody

→ Fig. 1 .

The high-voltage battery can be charged immediately or timer-controlled (→ Timer-controlled

charging, Operation). Always observe the safety warnings →

.

Always deactivate the vehicle's drive system before charging (→ Deactivating the vehicle’s drive

system, Operation).

Charging options

—Charging the vehicle using a mains socket or charging station (“alternating current”) (→

Alternating current (AC), Operation).

—Home charging station (wall box) (“alternating current”) (→ Charging at a home charging

station, Operation).

—Fast charging at a charging station (“direct current”) (→ Direct current (DC), Operation).

For alternating current charging, Volkswagen recommends charging the high-voltage battery at

the wall box or charging station with maximum charging power. This results in higher efficiency

compared with charging using a mains socket.

Residual current protection

The vehicle is protected against direct current residual currents (DC residual current). This

prevents DC residual currents that can occur during charging from flowing into the domestic

electrical installation via the charging cable and impairing the function of a residual-current

circuit-breaker (in Germany, for example, residual current circuit breaker type A) during the

charging procedure.

Night current

Your electricity provider may offer cheaper electricity tariffs at night that you can use to charge

the high-voltage battery. In order to use these periods, a preferred charging period can be

defined in the e-manager battery management or at the wall box.

High-voltage battery guarantee

The new car warranty from Volkswagen AG also covers the vehicle's high-voltage battery (→

Guarantee for high-voltage battery, Description).

All batteries deteriorate with age, depending on their service life and how they are used. To

maintain the high-voltage battery in a good and reliable condition for as long as possible, it is

important to know how to handle and care for the battery properly. Please read the information

in the following section carefully, and take it into account when using your vehicle.

WARNING

An incorrect battery charging process, a failure to adhere to general safety procedures, the use

of unsuitable or damaged sockets and charging cables, charging on an unsuitable electrical

installation and improper handling of the high-voltage battery can cause short circuits, electric

shocks, explosions, fire, serious burns, injuries and death.

●

Always adhere to the stipulated sequence of steps in order to avoid the risk of an electric

shock and serious injuries caused by residual energy in the electrical storage system. Never

disconnect the cable during the charging process.

●

The charger with charging cable should only be connected to a socket that is protected from

water, moisture and other liquids.

Only charge the high-voltage battery on properly installed, tested and undamaged power

sockets as well as on a fault-free electrical installation. Have the sockets and electrical

installation checked by a qualified professional on a regular basis.

●

Never use damaged charging connectors or cables. Always check charging connectors and

cables for damage before use.

Use only supplied charging cables or the charging station cable. If you need a replacement,

we recommend only using Volkswagen charging cables.

●

Never modify or repair electrical components, in particular those in the high-voltage system.

Never charge the vehicle in areas at risk of explosion. Components of the charging cable can

cause sparks and thus ignite flammable or explosive vapours.

●

Never use the charging cable together with an extension cable, a cable reel, a multiple

socket outlet or an adapter such as a travel adapter or timer.

●

Always protect electrical connectors from water, moisture and other liquids.

For safety reasons, no other work should be carried out in or on the vehicle during the

charging process.

●

Always end the charging process before disconnecting the mains plug. Otherwise, the

charging cable and the electrical installation could be damaged.

The connecting cable must always be removed from the vehicle before starting the vehicle.

Mount the protective caps and close the charging socket flap.

Never charge multiple vehicles on the sockets in a single fuse circuit at the same time. Use a

different fuse circuit for charging other vehicles. Always comply with the power rating for

the fuse circuit being used. If necessary, contact a qualified electrician.

WARNING

Driving when the charge level of the high-voltage battery is too low can lead to the vehicle

breaking down when in traffic, and can lead to accidents and serious injuries.

NOTICE

Frequently charging the high-voltage battery with a high charging power can lead to a

permanent reduction in the charging capacity. Charge the high-voltage battery mainly with a

low charging power, e.g. at a home charging station (wall box) or tested mains socket.

NOTICE

If the vehicle is parked for a long period with a discharged high-voltage battery, irreversible

damage can be caused to the high-voltage battery.

●

Always charge the high-voltage battery without delay.

The high-voltage battery can only be charged at charging stations that meet the

requirements of the corresponding country and at least the following standards:

− IEC 61851 and IEC 62196 (Europe).

− GB/T 18487 and GB/T 20234 (China) in the 2015 version.

− SAE J1772 and CHAdeMO (Japan).

Charging of the high-voltage battery can be subject to limitations in very low and very

high temperature conditions.

lamp lights up yellow.

A text message may also be shown on the instrument cluster display (→ Charging operations,

FAQ). Additionally, audible warnings will sound.

Charge the high-voltage battery as soon as possible to prevent the vehicle from breaking down.

WARNING

Driving when the charge level of the high-voltage battery is too low can lead to the vehicle

breaking down when in traffic, and can lead to accidents and serious injuries.

●

Always make sure the high-voltage battery has sufficient charge!

WARNING

When the charge level of the high-voltage battery reaches the “reserve range”, this may result

in changed vehicle handling, e.g. different acceleration response of the vehicle.

●

Always adapt your speed and driving style to suit visibility, weather, road and traffic

conditions as well as the charge level of the high-voltage battery.

NOTICE

Self-discharge of the high-voltage battery, e.g. due to the vehicle standing for periods of

several months, can lead to the high-voltage battery being damaged if ambient temperatures

are high and the high-voltage battery has a low charge level.

●

Always make sure the high-voltage battery has sufficient charge!

The range can also be increased by reducing or switching off convenience consumers,

e.g. seat heating or air conditioning. For more information, open the Range monitor in

the e-displays menu of the Infotainment system (→ Vehicle settings menu, Operation)

The range for electric driving may be reduced at very low outside temperatures when the

high-voltage battery is consequently very cold.

(→ e‑manager, Description).

Temperature monitoring

The charging cable is equipped with a temperature monitoring function on the safety device and

mains plug. The temperature monitoring function is triggered if the charging cable overheats,

e.g. if it had previously been stored in an overheated luggage compartment or strong sunlight.

When the charging current is reduced by the safety device, the warning lamp for the mains

connector → Fig. 1 5 or safety device 6 flashes red. One or more indicator lamps → Fig. 1

1 , 2 , 3 light up or flash green. As soon as the charging cable has cooled down enough, the

charging current is automatically increased again.

When the charging process is interrupted by the safety device, the indicator lamp for the vehicle

3 also goes out. Remove the charging cable and leave it to cool. If the error occurs again, seek

expert assistance.

Fault displays

In the event of a fault display with one or more red warning lamps without a status indicator, the

charging process is interrupted or terminated. Go to a qualified workshop.

Fault in the electrical installation

If the safety device detects a fault in the power supply, the indicator lamp for the earth wire

→ Fig. 1 4 lights up or flashes yellow or the indicator lamp for the mains connector → Fig. 1

5 lights up or flashes red without displaying a status indicator. The charging process will be

interrupted. Check whether you can charge the vehicle with another mains plug.

Have the mains socket or electrical installation checked by a specialist electrician.

NOTICE

Find out about the maximum charging current that can be set for charging at a domestic mains

socket. The maximum charging current is 8 amps in Finland, France and Switzerland and 6

amps in Denmark. Volkswagen recommends using the factory-supplied charging cables in

these countries.

NOTICE

In Norway, the function of the charging cable may be limited for technical reasons. Volkswagen

recommends only using the supplied charging cable in Norway.

If the vehicle is connected to the power grid via an additional connection or is located in

direct proximity to high-voltage lines during the charging process, charging at a mains

socket may not be possible. Additional connections to the power grid:

− Connection of a charger for 12-volt vehicle battery.

− Contact with working equipment connected to the power grid, e.g. lifting platform.
