1. About the Murano HYBRID
This
hybrid electric vehicle (HEV) uses two types of batteries. One is a 12-volt battery that is the same as
the battery in vehicles powered by internal combustion engines. The 12-volt battery is located in the front of
the vehicle on the left side of the engine compartment. The other is the high-voltage battery for the traction
motor which propels the vehicle. The high-voltage battery is located under the center console between the
driver’s and passenger’s seats with service plug access through the center console area storage bin.
When the high-voltage battery level is low, engine output is used to generate power from the traction motor
and charge the high-voltage battery. Additionally, the vehicle system can recharge the high-voltage battery
by converting driving force into electricity while the vehicle is decelerating or being driven downhill. This is
called regenerative charging.

DC/DC
Converter Inside the centerconsole area
(mounted right of
high-voltage battery) The DC/DC converter reduces the voltage of
the high-voltage battery to provide power to
the 12-volt battery in order to operate the
vehicle’s electric components (headlights,
audio system, etc.) .
Service Plug Center console
(inside storage bin
under access door) This is used to disable the high-voltage system.
High-voltage
Battery
Inside the center
console area
(between the front
driver’s and
passenger’s seats)The high-voltage battery stores and outputs
DC power (Maximum voltage 144V) needed to
propel the vehicle.
Traction Motor
Engine compartment
(built-into the
transmission)Converts three-phase alternating current (AC)
power to drive power (torque) which propels
the vehicle.
Traction Motor
Inverter
Engine compartment
(front driver side)Converts the DC power stored in the high-
voltage battery to three-phase AC power and
controls motor torque (revolution) by regulating
the motor current. The inverter has a built in
high-voltage capacitor.
12-volt Battery
