Starting And Stopping The Combustion Engine In Twin Engine - Volvo XC40 TWIN ENGINE 2019 Owner's Manual

STARTING AND DRIVING
||
Hybrid battery - The function of the hybrid
battery is to store energy. This receives
energy by charging from the power grid or
by means of regenerative braking. It pro-
vides energy for electric operation as well
as for temporarily operating the electric air
conditioning during the preconditioning of
the passenger compartment.
Internal combustion engine - The internal
combustion engine starts when the
energy level in the hybrid battery is insuffi-
cient for the engine power that the driver
requests.
Super condenser – Provides energy to
start the car, which saves the regular 12 V
battery.
Electric motor - Powers the car in electric
operation. If necessary, provides extra tor-
que and power during acceleration. Recy-
cles brake energy to electrical energy.

Starting and stopping the
combustion engine in Twin Engine
An advanced control system determines the
extent to which the car is driven on internal
combustion engine, electric motor or both in
parallel. During electric operation, the car
may sometimes need to start the internal
combustion engine automatically due to
external circumstances, e.g. in low outside
temperatures, which is completely normal. In
addition, the internal combustion engine
always starts when the hybrid battery rea-
ches its lowest state of charge.
Climate settings at low temperatures
In low outside temperatures, the internal com-
bustion engine sometimes starts automatically
in order to achieve the desired passenger
compartment temperature and air quality. The
amount of time that the internal combustion
engine runs can be affected by
lowering the temperature
•
reducing the fan strength
•
activating drive mode Pure
•
Electric operation in low or high
temperatures
In low or high outside temperatures, the car's
range and output for electric operation may be
reduced and affect how often the internal
combustion engine is started automatically.
