be plugged into the charging dock.

If no timer is programmed, the charging cycle starts immediately.

When the charging cable is plugged into the vehicle, the
charging plug is locked and cannot be removed. This is
indicated by the yellow status LED.

If a charging timer is programmed, but the state of charge
of the high voltage battery is less than 60%, the charging
cycle starts immediately until the state of charge reaches
approximately 60%. If the instant charge button is
pressed, the charging cycle stops and timer programming
is activated.

The charging cycle starts when the selector lever is in
position P and the operating unit is connected to the AC
voltage source.

The active charging cycle is indicated by the flashing LED on
the relevant button (see page 27).

Hybrid manager
The software of Engine Control Module has been extended
to include the hybrid manager function.

The following hybrid-specific functions of the vehicle are
controlled by the hybrid manager.

• Operating strategy.
• Torque distribution to the Electro-drive Drive Motor and
the internal combustion engine.
• High voltage coordinator.
• Recuperation under braking and acceleration.
• Control of the coolant circuits.

Operating strategy
The operating strategy is configured to operate the vehicle
efficiently using both drive systems. Taking the ambient
conditions and information from other control modules as
well as the driving profile into account, the system decides
whether to use the internal combustion engine, the e-machine or both.

Electric driving also requires enabling signals from other
control modules. A low state of charge in the high voltage
battery, a too-low ambient temperature, high torque
demand or high cabin heating demand may necessitate
starting the internal combustion engine.

High voltage coordinator

Recuperation under braking and
acceleration

In its capacity as a high voltage coordinator, the hybrid
manager monitors and coordinates all high voltage components. It enables activation of the high voltage system and
controls the displays for hybrid operation and display of
messages for the driver.

The hybrid manager controls over-run and braking recuperation functions based on the position of the accelerator or
brake pedal, the state of charge of the high voltage battery,
the vehicle's speed and driving stability criteria.

Plug-in hybrid modes
Electric driving (EV)
When the ignition is on, EV mode is active and the vehicle
preferentially runs on electric-only mode provided the
conditions for this are met.
EV mode is only active if the state of charge of the high
voltage battery is sufficient and the following conditions
are met:
• The temperature of the 12-volt battery and of the high
voltage battery is not less than approximately
14 °F (-10 °C).
• The vehicle is not travelling faster than approximately.
80 mph (130 km/h).
• No kick-down is performed.
• The selector lever is not engaged in the S position.

627_066a

If one or more of the above conditions is not met, EV mode
is deactivated.
Use battery charge (Hybrid Auto)
A decision is made based on the driving profile whether to
start in Hybrid mode or to run on electric power.
When the route guidance function is active in the navigation system, the use of electrical power is optimized
through moderate recharging or startup of charging stations based on the predictive route data.
Hold battery charge (Hybrid Hold)
During vehicle operation, the state of charge of the high
voltage battery is held at a constant level. The vehicle runs
in Hybrid mode and uses only a small portion of the battery
charge.

Increase battery charge (Hybrid Charge)
During vehicle operation, the high voltage battery is
charged by the internal combustion engine more intensively (this involves higher fuel consumption) in order to
achieve longer electrical range, for example, at the destination.
Sport mode
Moving the selector lever into tiptronic or S reveals the
sporty side of the Audi A3 Sportback e-tron. Full drive
power is now available to the driver at any time, and the
high voltage battery is continuously recharged. Increased
over-run torque boosts recuperation capacity and provides
a sporty driving feel.

Information
These settings can be made in the "Car" menu under "Systems" in the menu item "e-tron mode" or by pressing the Electric
Drive Button several times.

Climate control
Cooling systems, climate control and thermal management
The cooling and climate control systems of the A3 Sportback e-tron provide passenger comfort, cooling of the
internal combustion engine, transmission and high voltage
components. All components are integrated into the
various cooling circuits.

In the various operating states, for example in electric drive
mode or in Boost mode, the cooling circuits provide the
optimal coolant flow in order to ensure operational reliability,
a high level of passenger comfort and a high overall level of
efficiency.

The thermal management system enables the components
to reach their operating temperatures quickly. Passenger
comfort has the highest priority.

When the vehicle is driven in electric-only mode, the
High-voltage Heater heats the engine coolant for the passenger compartment heat exchanger. It is bolted to the
vehicle underbody and connected to the High Voltage
Battery Charger by a high voltage line. The integrated High
Voltage Heater (PTC) Control Module is controlled by the
Climatronic Control Module.

Audi has developed special connect services for the e-tron.
They allow specific information to be retrieved by smartphone and web portal as well as individual functions to be
controlled by a smartphone. These services are available as
standard in the Audi A3 Sportback e-tron and have to be
activated by the customer.
This information can be retrieved via a smartphone app and
the A3 e-tron website @ www.etron.audiusa.com. Data on
vehicle status can be retrieved. This includes current state
of charge, remaining electrical range and vehicle location.
Information on recent trips, such as average electrical
consumption, is also available.

The charging cycle and the air conditioning system can be
started immediately by the app or after a specified time
has elapsed (using a customizable departure timer), allowing the user to ensure that the vehicle is charged up and
optimally pre-conditioned before driving. The combination
of charging cycle and preconditioning enable the vehicle to
retain its full electrical range. If the vehicle is ready for
charging, the power required to cool or heat the passenger
compartment is drawn from the wall plug without discharging the vehicle's high voltage battery.
