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

2-2 High Voltage-Related and 12-Volt-Related Component Locations and Descriptions
NOTE:Components with white number in black background are high voltage components.
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/DC Converter Trunk area (mounted
to top of high volt-
age 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 vehi-
cle’s electric components (headlights, audio
system, etc.) .

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) ,

voltage between each of the high voltage com-ponents.
Electric Air Condi-
tioner Compressor Engine compart-
ment (front driverside) Air conditioner compressor
Traction MotorInverter Engine compart-
ment (right rearside) Converts the DC power stored in the high volt-
age battery to three-phase AC power and con-
trols motor torque (revolution) by regulating the
motor current. The inverter has a built in high
voltage capacitor.
Traction Motor Built-into the trans-
mission 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 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
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.

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. Roadside Assistance Response Steps
•NEVER assume the Q70 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.
