### Efficient thermal architecture that reduces the electricity required.

The EQB's sophisticated thermal architecture works very efficiently: a heat pump ensures that the waste heat from the electric drive can be used for the cabin heating - this reduces the need for battery power for the heating enormously and thus increases the range
An overview of the operating mechanisms of the EQB heat pump:

• Efficient reheating with recirculated air: Due to a high proportion of recirculated air, less (fresh) air needs to be heated. To reduce the tendency for the windows to mist up, the vehicle cools the recirculating air, thereby removing moisture. The heat extracted is fed back into the interior via the water-cooled condenser and the heat exchanger – in other words, the heat is "recycled".
• Use of the waste heat from the electric powertrain.
• Use of the waste heat from the high-voltage battery: if the temperature of the battery is above a threshold, the waste heat can be used to heat the interior.
