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) ,
under floor pan,
engine compartment Orange-colored power cables carry high DC
voltage between each of the high-voltagecomponents.

4-1.1 Jump Starting Procedures
NOTE:Jumper cable connections under the hood of the Q50 HYBRID are not connected directly to
a battery. They are connected to chassis ground and a fuse box terminal. Refer to the
following instructions and the above illustration.
1. If the booster battery is in another vehicle (A) , position the two vehicles (A and B) to bring the12-volt battery and fuse box into close proximity to each other.
DO NOT allow the two vehicles to touch.
2. Apply the parking brake. Move the selector lever the P (Park) position. Switch off all unnecessary electrical systems (headlights, heater, air conditioner, etc.) .
3. Remove fuse box cover on the Q50 HYBRID and connect jumper cables in the sequence as illustrated ( ) .
For models with a steering wheel lock mechanism:
If the 12-volt battery is disconnected or discharged, the steering wheel will lock and cannot be
turned. Supply power using jumper cables before pushing the ignition switch and disengaging
the steering lock.
• Always connect positive (+) to positive (+) and negative (-) to body ground (for example, as illustrated) , not to the 12-volt battery.
• Make sure the jumper cables do not touch moving parts in the engine compartment and that the cable clamps do not contact any other metal.
• If the hybrid system does not start right away, push the ignition switch to the OFF position and wait ten (10) seconds before trying again.
4. Start the engine of the booster vehicle (A) and let it run for a few minutes.
