Battery diagnosis
Battery diagnosis continuously determines the state of the battery.
Sensors determine battery voltage, battery current and battery
temperature. This determines the current state of charge and the
power of the battery .
Idling current management
Idling current management reduces energy consumption while the
vehicle is standing. With the ignition switched off, it controls the
energy supply to the various electrical components. Data from
battery diagnosis is considered.
Depending on the battery's state of charge , individual consumers are
gradually turned off to prevent excessive discharge of the battery and
thus maintain starting capability.
Dynamic energy management
While the vehicle is being driven, dynamic energy management
distributes the energy generated according to the needs of the indi­
v idual components. It regulates consumption, so that more electrical
energy is not being used than is being generated and ensures an
optimal state of charge for the battery.
[ i] Tips
• But even energy management cannot negate the limits of physics.
Consider that the power and life of a battery are limited.
• If starting ability is threatened, you are informed by a warning
=> page 196, "Driver notification in the instrument cluster display". •
What you should know
The highest priority is given to maintaining starting capa­
bility.
The battery is severely taxed in short-distance driving, in city traffic
and during the cold time of year. Abundant electrical energy is
Controls and equip­
ment Safety first Vehicle operation
required, but only a little is generated. It is also critical if the engine
is
not running and electrical components are turned on. In this
instance energy is being consumed but none is being generated .
It is in precisely these situations that you will notice energy manage­
ment actively regulating the distribution of energy.
Vehicle stands for an extended period
If you do not drive your vehicle over a period of several days or weeks,
electrical components are gradually cut back or switched off. This
reduces energy consumption and maintains starting capability over a
longer period.
Take into consideration that when you unlock your vehicle, some
convenience functions, such as the remote key or power seat adjust ­
ment, may not be available. The convenience functions will be avail­
able again when you turn on the ignition and start the engine .
With the engine turned off
If you listen to the radio, for example, with the engine turned off, the
battery is being discharged.
If starting capability is jeopardized due to energy consumption, a
message appears in the driver information display.
You have to start the engine to charge the battery.
With the engine running
Although electrical energy is generated when the vehicle is being
driven, the battery can become discharged. This happens mostly
when little energy is being generated and a great deal consumed and
the battery's state of charge is not optimal.
To bring the energy balance back into equilibrium, consumers which
require especially large amounts of energy are temporarily cut back
or switched off. Heating systems in particular require a great deal of
energy . If you notice, for example , that the heated seats* or the
heated rear window are not heating, they have been temporarily cut
back or switched off. These systems will be available again as soon as
the energy balance has been restored. .,

Vehicles not driven for long periods and short­
distance operation
If you do not drive your vehicle for several days or weeks, e lectrical
consumers are gradually scaled back or switched off. Th is reduces
energy use and ensures the vehicle will be able to start after long
periods of time~
page 194. Some convenience functions such as
opening with the remote control key may not be available. These
convenience functions will be available again once you switch the
ignition on and start the engine. Even when consumers are switched
off, the battery will become deeply discharged by stand-by power
consumers if the vehicle is not driven for several months . Deep
discharging results in a chemica l reaction that destroys the inside of
the battery. The battery must be charged every month to prevent th is

system* will not work.
Winter operation
Cold weather places higher demands on the battery. This results in
reduced starting abi lity. Have the battery checked and recharged if
necessary before the cold weather beg ins.
Avoid unnecessary power consumption, part icularly in city traffic or
when travel ing on ly short distances. Let your author ized Audi dealer
