Charging the hybrid battery
In addition to the conventional fuel tank, your
vehicle is also equipped with a rechargeable
lithium-ion hybrid battery.
The hybrid battery can be recharged using the
charging cable stored in a storage space in the
cargo compartment.
WARNING
The hybrid electrical system in your vehicle
uses high voltage electrical current. Any dam-
age to this system or to the hybrid battery
may result in the danger of overheating, fire,
or serious injury. If the vehicle is involved in a
collision or subjected to flooding, fire, etc.,
have it inspected by a trained and qualified
Volvo service technician. Prior to this inspec-
tion, the vehicle should be parked outdoors at
a safe distance from any building or poten-
tially flammable materials.
The hybrid battery's charging time depends on
the charging current used.
NOTE The capacity of the hybrid battery diminishes
somewhat with age and use, which could
result in increased use of the gasoline engine
and consequently, slightly higher fuel con-
sumption.
WARNING If the hybrid battery needs to be replaced, this
may only be done by Volvo retailer or author-
ized Volvo workshop.
Charging cable handle and charging socket.
Charging status is indicated in three ways:
• The indicator lights in the charging module
(the unit connected to the wall outlet).
• Indicator light in the vehicle's charging
socket.
• Images and text in the instrument panel.
The hybrid battery's charging process also
charges the vehicle's start battery.
If the hybrid battery's temperature is below
-10 ºC (14 ºF) or above 40 ºC (104 ºF), some of
the vehicle's functions may be reduced or not
available at all. The electric motor cannot be used if the battery's
temperature is too low or too high. If the PURE
drive mode is selected, the gasoline engine will
start.
Charging using the gasoline engine
The vehicle generates electrical current to charge the
battery, e.g. when the driver lightly presses the brake
pedal or when engine braking is used on downgrades.
The vehicle can also generate current to the
hybrid battery to charge it.
• The hybrid battery can also be recharged by
lightly depressing the brake pedal, i.e. during
light braking. This converts the vehicle's
kinetic energy to electrical energy, which is
used to charge the hybrid battery.
• In gear position B, the electric motor brakes
the vehicle when the accelerator pedal is

released and the hybrid battery is recharged
at the same time.
• The combustion engine can also help
recharge the hybrid battery.

• Long-term storage of vehicles with hybrid
batteries (p. 421) Charging current
Charging current is used to charge the hybrid
battery and precondition the vehicle. Charging is
performed by connecting a charging cable
between the vehicle's charging socket and a
120/240 V electrical socket (alternating cur-
rent).
When the charging cable is activated, a message
will be displayed in the instrument panel and an
indicator light in the vehicle's charging socket will
illuminate. Charging current is primarily used for
battery charging, but is also used for precondi-
tioning. The vehicle's start battery is charged
along with the hybrid battery.
CAUTION
Never detach the charging cable from the
120/240 V outlet (AC, alternating current)
while charging is in progress – the
120/240 V outlet could be damaged in such
circumstances. Always interrupt charging first
and then disconnect the charging cable – first
from the vehicle's charging socket and then
from the 120/240 V outlet.
NOTE •
In extremely cold or hot weather, part of
the charging current is used to heat/cool
the hybrid battery and the passenger
compartment, resulting in a longer charg-
ing time.
• The charging time is longer if precondi-
tioning has been selected. The time
required depends primarily on the ambi-
ent temperature. There are normally several 120/240 V power
consumers in one fuse circuit, which means that
more than one power consumer (e.g. lighting,
vacuum cleaner, electric drill, etc.) may use the
same fuse.
