Volkswagen ID.4: Warning signs for the high-voltage system

Where can warning signs be attached?

• Covers and caps behind which there are high-voltage components.
• All high-voltage components, including the high-voltage battery.
• Under the hood.

Warning signs

The following illustrations may differ slightly from the warning signs on the vehicle.

Fig. 1 Warning sign on the battery charger and other high-voltage components.

Fig. 2 Warning signs on high-voltage components.

Fig. 3 Warning sign in the hood space.

These warning signs indicate a high electrical voltage → fig. 1, → fig. 2, → fig. 3.

Fig. 4 Warning sign on the battery charger.

This warning sign → fig. 4 indicates that parts of the high-voltage system can become very hot and must not be touched.

1. Exposure to high voltages can result in serious injury or even death. Never touch the battery terminals with your fingers or with tools, or allow jewelry or other metal items in contact with your body to touch the battery terminals.
2. The high-voltage battery contains hazardous liquids and solids. Escaping gas can cause serious chemical burns and could blind you. When working on the high-voltage battery, always wear suitable protective eyewear and protective clothing to prevent battery fluid from coming into contact with your skin and eyes. If battery fluid does come into contact with your skin or eyes, run clean water over the affected areas for at least 15 minutes and seek medical attention immediately.
3. Under certain circumstances, the high-voltage battery can catch fire. Never expose the high-voltage battery to fire, sparks or naked flames. To prevent damage and fluid leakage, always handle the high-voltage battery with care.
4. Keep children away from the high-voltage battery at all times.
5. Further information and warnings can be found in the Owner's Manual and in the workshop information.
6. Improper handling of the high-voltage battery can result in serious injury or even death. Never remove the cover from the high-voltage battery and never disassemble the high-voltage battery.
7. Improper handling of the high-voltage battery can result in serious injury or even death. Have all maintenance procedures on the high-voltage battery performed by fully qualified professionals. Never modify the high-voltage battery. When the high-voltage battery is open, do not allow it to come into contact with water or other liquids. Liquids can cause short-circuiting, electric shock and burns.

Introduction

Requirements

✓ Vehicle's drive system is deactivated.

✓ Charging cable and charging infrastructure are working correctly and have been checked→ .

Types of charging

• AC (alternating current) charging at a charging station or wall box (→ Charging processes).

  It is charged with a high charging power. The maximum achievable charging power results from the charging station used, the charging cable used and the equipment of the battery charger.

• AC (alternating current) charging at a mains socket (→ Charging processes).

  The household's electrical installation must be checked and must be working correctly→ . Plenty of charging time should be scheduled in, e.g. overnight.

• DC (Direct Current) Charging at the Charging Station or Wall Box (→ Charging processes) : It is charged with a very high charging power. This significantly reduces the charging time. Please read the notes on frequent charging with direct current (DC ) → .

NOTICE

A very high charging power is used for fast-charging with direct current (DC). Frequent fast-charging can permanently reduce the battery capacity of the high-voltage battery.

• The high-voltage battery should be mainly charged with alternating current (AC ) at a charging station or wall box.

When charging with alternating current (AC ), it is recommended to charge with maximum charging power at a charging station or wall box. This achieves a higher efficiency compared to charging with a mains socket.

Please note the technical information about your vehicle's charging power. For more information contact an authorized Volkswagen dealer or authorized Volkswagen Service Facility.

WARNING

Failure to comply with the operating and safety instructions or improper use of the high-voltage battery and charging cable could result in a short circuit, electric shock, explosions and fire. There is a risk of damage and serious or fatal injuries.

• Always end the charging process before removing the mains plug to avoid coming into contact with residual power in the charger.
• Pay attention to the safety and operating information for the supplied charging cable.
• In the household, only use a connection that is suitable for electric vehicles and has been installed and tested by qualified professionals.
• Never charge in areas where there is a risk of explosion. Charging cable components can trigger sparks and can ignite flammable or explosive vapors.
• Always protect electrical connections from direct contact with water, damp, and other fluids.
• Do not carry out any other work on or around the vehicle during charging for safety reasons.

WARNING

Driving with a low high-voltage battery charge level can cause the vehicle to become stranded in traffic. Accidents and serious injuries could result.

• Always charge the high-voltage battery before starting a journey.

The high-voltage battery can only be charged at charging stations which meet the requirements of the country and abide by at least the following norms:

• IEC 61851 and IEC 62196 (Europe).
• GB/T 18487 and GB/T 20234 (China) in the 2015 version.
• SAE J1772 (Japan).
• SAE J1772 (USA and Canada).

Sticker for the correct charging socket

Fig. 1 Sticker for AC charging and type 2 plugs A on the vehicle and B on the charging station.

Fig. 2 Sticker for DC charging and CCS plugs on the vehicle A with a voltage up to 500 V and B up to 920 V.

The symbols on the stickers indicate whether the charging system of the vehicle is compatible with the local charging socket → .

The markings may be located on the vehicle charging socket, on the components at the local charging infrastructure (charging station), and on the charging cable.
