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.RAG–5

2. Basic High-voltage Information
2-1 Battery Information
The Q50 HYBRID utilizes two batteries in order to supply both high and low voltage.
2-1.1 12-Volt Battery• The Q50 HYBRID contains a conventional lead-acid12-volt battery.
• The 12-volt battery is located in the trunk, on the left side, concealed by a trim cover (A) .
• The 12-volt battery is charged by the high-voltage battery through the DC/DC converter.
2-1.2 High-voltage Battery • The Q50 HYBRID contains a high-voltage battery.
• The high-voltage battery is mounted in the trunk areabehind the rear seat, enclosed in a metal case and
concealed by trim cover.
• The high-voltage battery stores energy at approximately 346 - 400 volts DC.
• A vent hose is provided to exhaust gasses outside the vehicle if necessary.
• An air vent (A) is located on the rear left hand lower C-pillar trim for battery cooling.
The high-voltage battery supplies power to the following: • High-voltage harnesses
• DC/DC converter
• Traction motor inverter
• Traction motor
• Electric air conditioner compressor

No. Component Location Description Traction Motor Inverter
Engine compartment
(right rear 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.
Traction Motor Built-into the
transmission Converts three-phase alternating current (AC)
power to drive power (torque) which propels
the vehicle.
High-voltageBattery
Trunk area (behind
rear seat back) The high-voltage battery stores and outputs
DC power (Maximum voltage 400V) needed to
propel the vehicle.
DC/DC Converter Trunk area (mounted to top 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 Trunk area (below
parcel shelf; behind
access door in trimpanel) This is used to disable the high-voltage system.
12-volt Battery Trunk area (left side
behind trim panel) A lead-acid battery that supplies power to the
low voltage devices.

2-4 High-voltage Safety Measures
Circuit insulation The high-voltage positive (+) and negative (-) circuits are insulatedfrom 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 may 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.

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

3. Roadside Assistance Response Steps
•NEVER assume the Q50 HYBRID is shut OFF simply because it is quiet.
•
If the vehicle is damaged and you are not sure about the condition of the electric
vehicle system, contact first responders immediately. If the vehicle is damaged, the
high-voltage system should be shut down by first responders while following the
procedures in the First Responders Guide and while wearing appropriate Personal
Protective Equipment (PPE) .
•
If the READYindicator is ON the high-voltage system is active.
•
If possible, be sure to check the READYindicator on the instrument cluster and
verify that the READY
indicator is OFF and the high-voltage system is stopped.
• Some of the under hood parts get hot and may cause serious burns. Use caution when working on or around these parts.
