The high-voltage battery is used as an additional buffer of unused energy from the home. If necessary, the vehicle can supply energy
back into the home.
Prerequisites
The availability of bidirectional charging in the vehicle is country-dependent. This also applies with respect to a suitable home energy
management system.
Vehicle with a suitable high battery capacity.
Compatible home energy management system (HEMS) with energy storage unit.
A charging location has been created in the Infotainment system.
First ask a suitably qualified workshop for information on home energy management systems that are suitable for this.
Volkswagen recommends using an authorised Volkswagen repairer.
Function
The home energy management system controls the charging and discharging processes of the high-voltage battery as required, e.g.
based on the availability of solar power, and performs the required adjustments in the vehicle.
In addition, the energy from the high-voltage battery can be used for an emergency power mode, e.g. for a household without a mains
connection or in the event of a power failure.
Read and observe the operating instructions and functions of the home energy management system.
Emergency power mode is displayed only in the home energy management system.
Discharging is possible only when the battery temperature is between around -15°C (around +5°F) and around +40°C (around
+104°F). This does not apply to emergency power operation of the home energy management system.
Setting bidirectional charging and discharging in the Infotainment system
1. Connect the vehicle to the home energy management system.
2. Tap the drop-down list for the charging process in the Infotainment system, e.g. in the Charging menu.
3. Select Bidirectional charging or Discharge .
The charging or discharging operation starts automatically.
4. Check the desired battery charge limits in the profile of the charging location and adjust if necessary.
The upper battery charge limit for charging is restricted to a maximum of 80%.
Delayed charging for a departure time is not possible with bidirectional charging.
Restricting power extraction from the high-voltage battery
1. Set the lower battery charge limit in the charging location profile to the desired value.
The charge level drops to a maximum of 20% during discharging.
You can view the amount of power extracted and the current charging or discharging power on the home energy management
system. The vehicle discharges with a maximum power of around 10 kW.
When the intended operating time (4000 h) or amount of energy (10000 kWh) in the
Settings menu is used up, only
charging controlled by the infrastructure is available within the bidirectional charging function. The discharge function is no
longer available. Please contact an authorised Volkswagen repairer for further information.
