1. About the INFINITI Q50 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 behind
the rear seat back with battery cable access through the trunk area. The other is the high-voltage battery for
the traction motor which propels the vehicle. The high-voltage battery is located behind the rear seat back
with service plug access through the trunk area.
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.

2-4 High-voltage Safety Measures
Circuit insulation
The high-voltage positive (+) and negative (-) circuits are insulated
from the metal chassis.
Reducing the risk of electrocution The high-voltage components and harnesses have insulated cases or orange-colored coverings which provide insulation and easy
identification.
The high-voltage battery case is electrically connected to the vehicle
ground. This connection helps protect the vehicle occupants and
emergency responders from high-voltage electrical shock.
Identification The high-voltage components are labeled “WARNING” similar to the
label shown below. All high-voltage harnesses are coated in orange.
2-4.1 Warning Labels WARNING/AVERTISSEMENT
To avoid serious injury, keep clear engine parts at all times. Engine ma\
y start at any time if the start switch and the the READY lamps
on the instrument panel are "ON". Make sure both lamps are "OFF" before \
working in the engine compartment. See Owners Manual.
P

our éviter des blessures graves, assurez-vous que les témoins START SWITCH et READY dans le tableau de bord sont éteints
(OFF) avant d'entreprendre tout travail à I'intérieur du compart\
iment moteur. Le moteur peut démarrer à tout moment si le contacte\
ur
d'allumage est à la position ON et que les témoins READY du tablea\
u de bord sont allumés. Assurez-vous que les deux
témoins sont éteints avant de travailler dans le compartiment mote\
ur. Reportez-vous au manuel du conducteur.

2-5 High-voltage Safety System
The
high-voltage safety system is intended to help keep vehicle occupants and emergency responders safe
from high-voltage electricity. • A high-voltage fuse provides short circuit protection inside the high-voltage battery.
• The high-voltage safety system is insulated from the metal chassis.
• Positive and negative high-voltage power cables are connected to the high-voltage battery and arecontrolled by normally open system main relays (SMR1 and SMR2) . When the vehicle is shut off,
the relays stop electrical flow from leaving the high-voltage battery. However, it can take
approximately ten (10) minutes for the high-voltage capacitor to fully discharge. • The high-voltage system and high-voltage capacitor may remain powered for up to
approximately
10 minutes after the vehicle is shut off. Personal Protective Equipment
(PPE) must always be worn when touching or working on high-voltage components
to avoid risk of electrical shock and severe personal injury or death.
• The high-voltage battery retains high-voltage at all times. PPE must always be worn when touching or working on high-voltage components to avoid risk of electrical shock and
severe personal injury or death.
• A ground fault monitor continuously monitors for high-voltage leakage to the metal chassis while the vehicle is running. If a malfunction is detected, the HPCM (hybrid powertrain control module) will
illuminate the hybrid system warning lamp in the instrument cluster.
•

The high-voltage battery relays (SMR1 and SMR2) will automatically open to stop the electrical flow
in front, side or certain rear collisions that are sufficient enough to activate the supplemental
restraint system (SRS) . Trunk

2-6 High-voltage Circuit Shut-Off System
This
vehicle is equipped with a system to shut off the current from the high-voltage battery by the following
methods: Service plug
Positioned in the center area of the high-voltage battery, this plug shuts off
the
output of high-voltage when manually removed.
System main relays
(located in the high-
voltage battery) Controlled by the ignition switch, these relays are powered by the 12-volt
system and shut off high-voltage from the high-voltage battery.
Emergency shut-off
system In the case of a collision (front and side collisions in which the air bags are
deployed, certain rear collisions) or certain system malfunctions this system
is designed to shut off the high-voltage from the high-voltage battery.
2-7 Preventing Electrical Shock 1. If it is necessary to touch any of the high-voltage harnesses or components, always wearappropriate Personal Protective Equipment (PPE) (refer to 3-1 Preparation Items (FRG–17)) .
Shut

off the high-voltage system by referring to 3-3.1 High-voltage System Shut-Down
Procedure

(FRG–20) .
2.

To avoid the risk of electrocution, NEVER touch the inside of the high-voltage battery with bare
hands after shutting off the high-voltage system. The high-voltage battery maintains charge even
though the high-voltage system is shut down. PPE must always be worn when touching or
working on high-voltage components.
3. Cover damaged high-voltage components with insulated tape.
2-8 Emergency Medical Equipment
The high-voltage system should not interfere with emergency medical equipment which must be used in or
near the vehicle at an accident scene.
