Volkswagen ID.4: Bidirectional charging

The high-voltage battery serves as an additional intermediate storage for any excess electricity produced. If necessary, the vehicle can feed electricity back into the home.

Requirements

✓ Vehicle with suitable, high battery capacity.

✓ Compatible home energy management system (HEMS ) with energy storage system.

✓ A charging location was created in the Infotainment system.

First, consult a qualified professional to determine which home energy management system is suitable.

Volkswagen recommends contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility.

System function

The home energy management system controls the charging or discharging process of the high-voltage battery as required, e.g. according to the availability of solar power in the household, and adopts the vehicle settings.

In addition, the home energy management system can use the electricity from the high-voltage battery during a power failure or for supplying a household without power supply.

Read and observe the operating instructions and the functions of the home energy management system.

The availability of bidirectional charging in the vehicle is country-dependent. This also applies to a suitable home energy management system.

Setting bidirectional charging and discharging

In the Infotainment system of the vehicle, you can choose between Bidirectional charging (charging and discharging) and Discharging (discharging only).

Time-delayed charging for a departure time is not possible.

Limiting the current drain

Set the minimum battery charge level in the Infotainment system to the desired value in order to limit the current drain. For this charging process, the value is limited to 20% for technical reasons.

Selecting a Charging Procedure

1. Switch the Infotainment system on.

2. Tap Charging in the main menu.

Or: When the charging connector is inserted into the unlocked vehicle, a screen with charging information is displayed automatically.

3. Tap the drop-down list for the charging procedure and select Bidirectional charging or Discharging.

The charging or discharging process starts automatically.

4. Check the preferred battery charge levels in the charging location profile.

The Control using a home energy management system function in the charging location profile does not need to be activated.

You can see the amount of the current being drained on your home energy management system. The vehicle discharges with a maximum output of about 10 kW.

To protect the high-voltage battery from damage, the use of the function is limited at the factory. If the maximum counter values for operating hours (4000 h) and energy volume (10,000 kWh) are reached in the Settings menu, contact an authorized Volkswagen dealer or authorized Volkswagen Service Facility.
