2017 INFINITI Q50 HYBRID trunk

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.
High-voltageHarnesses Trunk area (on high-
voltage battery) ,

5. Start the hybrid system of the vehicle being jump started (B) .
6. After starting the hybrid system, carefully disconnect the negative cable and then the positivecable ( ) .
7. Reinstall the fuse box cover.
NOTE:
If it is not possible to turn the hybrid system ON by following this procedure, it is
recommended you contact an INFINITI retailer immediately.
4-1.2 Shift Selector Lever Lock Release
If the 12-volt battery is low or discharged, the selector lever cannot be moved from the Park (P) position. If a
booster battery is not available, the selector lever lock can be manually released. To manually release the
selector lever lock, perform the following procedure: 1. Push the ignition switch to the LOCK or OFF position.
2. Apply the parking brake.
3. Remove the shift lock cover (A) using a suitable tool.
4. Push down the shift lock (B) as shown in the illustration.
5. Push the selector lever button (C) and move the selectorlever to the Neutral (N) position (D) while holding down
the shift lock.
