Drive Systems - Volvo XC60 Twin Engine 2020 Owner's Manual

STARTING AND DRIVING

Drive systems

Volvo Twin Engine combines a combustion
engine for the front wheels and an electric
motor for the rear wheels.
Two drive systems
Depending on the selected drive mode and
power available in the electric motor, the drive
systems can either be used separately or in
tandem.
The electric motor gets its energy from a
hybrid battery located under the tunnel con-
sole. The hybrid can be charged from a wall
outlet or in a special charging station. The
combustion engine can also charge the hybrid
battery using a special high-voltage generator.
Both the combustion engine and the electric
motor can generate power directly to the
wheels. An advanced control system coordi-
nates both the drive systems to help optimize
driving economy.
6 CISG (Crank Integrated Starter Generator) – combined high-voltage generator and starter.
422
Hybrid battery - The hybrid battery's func-
tion is to store electrical current. This
energy is provided by plugging the charg-
ing cable into an electrical outlet, through
regenerative braking or from the high-volt-
age generator. This provides current to
power the electric motor and to temporar-
ily power the electrical air conditioning to
precondition the passenger compartment.
Combustion engine - The combustion
engine starts when the charge level in the
hybrid battery is too low to provide the
power output requested by the driver.
6
High-voltage generator - Charges the
hybrid battery. Starter for the combustion
engine. Can provide the combustion
engine with extra electrical current.
Electric motor - Powers the vehicle using
electricity. Can provide extra torque and
power during acceleration. Provides elec-
trical all-wheel drive functionality. Regen-
erates braking energy into electrical cur-
rent.
