VW ID.4 2023 Owner's Manual ➜ Charging the high-voltage battery

Fig. 128 Warning sign on the high-voltage battery.  
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.  
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.  
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.  
Keep children away from the high-voltage battery at all times.  
Further information and warnings can be found in the Owner's Manual and in the workshop information.  
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.  
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.  
Charging the high-voltage battery  
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.  
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.  
The household's electrical installation must be checked and must be working correctly ⇒  
DC (Direct Current) Charging at the Charging Station or Wall Box Charging:  
. Plenty of charging time should be scheduled in, e.g. overnight.  
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)  
.
249  
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).  
Handling the high-voltage battery  
Please read the introductory information and heed the Warnings and Notice   
and Introduction.  
Reliability and battery capacity of a high-voltage battery  
A lithium-ion battery is generally subject to a physical and chemical aging and wearing process over its service life. Correct handling of the high-voltage battery can  
significantly contribute to a reliable battery state and a high usable battery capacity and range in the long-term. This makes it all the more important to comply with  
the following care instructions for the high-voltage battery. If you follow these care instructions, the vehicle can maintain its value for a long time.  
Also observe the applicable Volkswagen guarantee and warranty conditions for the high-voltage battery. For more information, contact your authorized Volkswagen  
dealer or authorized Volkswagen Service Facility.  
Charging recommendations  
Volkswagen recommends observing the following charging recommendations:  
For everyday use, set the maximum battery charge level to 80% in the Infotainment system Battery charge limits.  
Charge the high-voltage battery once the battery charge level is below 20%. Ideally avoid the high-voltage battery being fully discharged  
.
Charge the high-voltage battery to 100% before long journeys. Set a departure time in the Infotainment system Departure Times (time-delayed charging) a  
drive off as immediately after charging as possible.  
Avoid regular rapid charging with direct current (DC).  
NOTICE  
The high-voltage battery must not be manipulated for use as a stationary power source. This may lead to irreversible damage to the high-voltage battery.  
250  
Never make technical modifications to or tamper with the high-voltage battery and high-voltage components.  
Battery Care Mode  
The maximum battery charge level is automatically limited to 80 % for the next charging process.  
1. Tap HOME in the Infotainment system.  
2. Tap  
3. Tap  
Charging.  
Setup.  
4. Activate the function.  
Volkswagen recommends using the Battery Care Mode function for everyday use to protect the high-voltage battery.  
If charging at a certain departure time is activated, the function cannot be used.  
Periods when the vehicle is unused  
If you intend to leave the vehicle parked for longer periods, park it with a battery charge level between 40% and 70%.  
Ideally avoid high outside temperatures, especially in direct sunlight, when the vehicle is parked for longer periods.  
To improve convenience and performance, use stationary air conditioning when required (depending on the vehicle equipment), especially at temperatures  
below approx. -15 °C (approx. +5 °F) Operating the stationary air conditioning.  
NOTICE  
If the vehicle is parked for an extended period with a discharged high-voltage battery, the high-voltage battery may not be able to charge or the vehicle might not  
start. In the long-term, this can lead to irreversible damage to the high-voltage battery.  
Charge the high-voltage battery at regular intervals.  
The high-voltage battery has less power available in very low temperatures. If the battery charge level is also low, the driving power may also be limited for a  
short time after pulling away.
