2019 VOLVO XC90 TWIN ENGINE charging

||MAINTENANCE AND SERVICE
628
CAUTION
Only a modern battery charger with controlled
charge voltage should be used to charge the
starter battery. The rapid charging function
should not be used as this could damage the
battery.
NOTE
If both the starter battery and the hybrid bat-
tery are discharged, both batteries must be
charged. In such cases, it is not possible to
charge only the hybrid battery first.
The starter battery must have a certain level
of charge for it to be possible to charge the
hybrid battery.
CAUTION Failure to observe the following could cause
the infotainment energy save mode to tempo-
rarily stop working and/or a message in the
driver's display regarding the state of charge
of the starter battery may be temporarily
incorrect after an external starter battery or
battery charger has been connected:
The negative battery terminal of the vehi-
cle's starter battery must never be used
to connect an external starter battery or
battery charger – only the vehicle's neg-
ative charging point should be used as
a grounding point.NOTE If the starter battery becomes discharged too
many times, it will shorten its service life.
The service life of the starter battery is affec-
ted by several factors, such as driving condi-
tions and climate. The starting capacity of the
battery reduces gradually over time. The bat-
tery must therefore be recharged if the vehi-
cle is not used or a long period of time or if it
is only driven short distances. Severe cold fur-
ther limits the starting capacity.
To keep the starter battery in a good condi-
tion, the vehicle should be driven at least
15 minutes per week or the battery should be
connected to a battery charger with automatic
trickle charging.
A starter battery that is always kept fully
charged has the maximum service life.

MAINTENANCE AND SERVICE
631
Hybrid battery
The vehicle's electric motor is powered by a
rechargeable, maintenance-free, lithium-ion
hybrid battery.
NOTE The vehicle cannot be started if the hybrid
battery is discharged.
NOTE
If both the starter battery and the hybrid bat-
tery are discharged, both batteries must be
charged. In such cases, it is not possible to
charge only the hybrid battery first.
The starter battery must have a certain level
of charge for it to be possible to charge the
hybrid battery.
WARNING
Hybrid battery replacement may only be per-
formed by a workshop – an authorized Volvo
workshop is recommended.
CoolantThe hybrid battery's cooling system has its own
expansion tank.
CAUTION Filling the hybrid battery coolant should only
be performed by a workshop – an authorized
Volvo workshop is recommended.
Specifications for hybrid batteryType: Lithium-ion
Power reserve: 10.4 kWh.
NOTE
The capacity of the hybrid battery decreases
with age and use, which could result in
increased use of the combustion engine,
leading to higher fuel consumption and
reduced electric motor range.
