Volkswagen ID.4: Handling the high-voltage battery

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 (→ Delayed charging) and 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.

• 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 Charging.

3. Tap 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 ºC (approx. +5 ºF) (→ 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.
