audio INFINITI Q70 HYBRID 2015 Roadside Assistance Guide

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.
