1. About the INFINITI Q70 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 Q70 HYBRID utilizes two batteries in order to supply both high and low voltage.
2-1.1 12-volt Battery• The Q70 HYBRID contains a conventional lead-acid12-volt battery.
• The 12-volt battery is located in the trunk, left of high voltage battery, concealed by trim cover.
• The 12-volt battery is charged by the high voltage battery through the DC/DC converter.
2-1.2 High Voltage Battery • The Q70 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 approximately 346 volts DC (400V max.) .
• A vent hose is provided to exhaust gasses outside the vehicle if necessary.
• An air vent is located on the rear parcel shelf 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 High Voltage Battery Trunk area (behind
rear seat back) The high voltage battery stores and outputs
DC power (Maximum voltage 400V) needed to
propel the vehicle.
DC/DCConverter Trunk area (mounted
to top of high voltagebattery) 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 (below
parcel shelf; behind
trim panel left of high
voltage battery) A lead-acid battery that supplies power to the
low voltage devices.
High VoltageHarnesses Trunk area (on high
voltage battery) ,
under floor pan,
engine compartment Orange-colored power cables carry high DC
voltage between each of the high voltagecomponents.
Electric AirConditionerCompressor Engine compartment
(front driver side)
Air conditioner compressor
Traction MotorInverter Engine compartment
(rear passenger 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.

2-4 High Voltage Safety Measures
Circuit insulation The high voltage positive (+) and negative (-) circuits are insulated from themetal 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 label shown below. All high voltage harnesses are coated in orange.
2-4.1 Warning Labels
To avoid serious injury, keep clear of engine parts at all times. Engine may start at any time if

the start switch and the READY lamps on the instrum ent panel are "ON". Make sure both
lamps are "OFF" before working in the engine compartment. See Owners Manual.

ÏûµÆ
Pour 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 a l' intérieur du
compartiment moteur. Le moteur peut démarrer a tout moment si le contacteur d' allumage
est a la position ON et que les témoins READY du ta bleau de bord sont allumés. Assurez-vous
que les deux témonins sont éteints avant de travailler dans le compartiment moteur.

3-1.1 Personal Protective Equipment (PPE) Protective Wear Control
Perform an inspection of the Personal Protective Equipment (PPE) items before beginning work. Do not use
any damaged PPE items.
3-1.2 Daily Inspection
This inspection is performed before and after use. The worker who will be using the items should perform
the inspection and check for deterioration and damage.• Insulated rubber gloves should be inspected for scratches, holes and tears. (Visual check and airleakage test)
• Insulated safety boots should be inspected for holes, damage, nails, metal pieces, wear or other problems on the soles. (Visual check)
• Insulated rubber sheet should be inspected for tears. (Visual check)
3-1.3 Insulated Tools
When performing work at locations where high voltage is applied (such as terminals) , use insulated tools
meeting 1,000V/300A specifications.
3-2 Indications the High Voltage System is ON
If the READY
indicator is ON, the high voltage system is active.
Before disconnecting the 12-volt battery terminal, if necessary, lower the windows, unlock the doors, and
open the rear hatch as required. Once 12-volt battery is disconnected, power controls will not operate. RAG–16
