1. About the INFINITI M35h HYBRID

This hybrid electric vehicle (HEV) uses two types of batteries. One is a 12V battery that is the same as the battery in vehicles powered by internal combustion engines. The 12V battery is located behind the rear seat back with battery cable access through the trunk area. The other is the Lithium-ion (Li-ion) battery (high voltage) for the traction motor which propels the vehicle. The Li-ion battery is located behind the rear seat back with service plug access through the trunk area.
The high voltage Li-ion battery is recharged with an on-board DC/DC converter and generator powered by the engine. Additionally, the vehicle system can recharge the Li-ion battery by converting driving force into electricity while the vehicle is decelerating or being driven downhill. This is called regenerative charging.

2. Basic High Voltage Information

2-1 Battery Information

The M35h HYBRID utilizes two batteries in order to supply both high and low voltage.

2-1.1 12V Battery

• The M35h HYBRID contains a conventional lead-acid 12V battery.
• The 12V battery is located in the trunk, left of Li-ion battery, concealed by trim cover.
• The 12V battery is charged by the Li-ion battery through the DC/DC converter.

2-1.2 Li-ion Battery

• The M35h HYBRID contains a Li-ion high voltage battery.
• The high voltage battery is mounted in the trunk area behind the rear seat, enclosed in a metal case and concealed by trim cover.
• The high voltage battery stores approximately 346 volts DC (400V max.).
• The high voltage battery exhausts gases directly outside the vehicle through a vent hose.
AAYIA0064ZZ
• 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

mission
The Li-ion battery stores and outputs DC power (Maximum voltage 400V) needed to propel the vehicle.
The DC/DC converter reduces the voltage of the Li-ion battery to provide power to the 12V battery in order to operate the vehicle’s electric components (headlights, audio system, etc.).
This is used to disable the high voltage system.
A lead-acid battery that supplies power to the low voltage devices.
Orange-colored power cables carry high DC voltage between each of the high voltage com­ponents.
Air conditioner compressor
Converts the DC power stored in the Li-ion 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.
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 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 vehicle dismantlers
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 Label

from high voltage electrical shock.

2-5 High Voltage Safety System

The high voltage safety system is intended to help keep vehicle occupants and emergency responders safe from high voltage electricity.
• A high voltage fuse provides short circuit protection inside the high voltage battery.
• The high voltage safety system is insulated from the metal chassis.
• Positive and negative high voltage power cables are connected to the high voltage battery and are controlled by normally open system main relays (SMR1 and SMR2). When the vehicle is shut off, the relays stop electrical flow from leaving the high voltage battery. However, it can take up to ten (10) minutes for the high voltage capacitor to fully discharge.
AAYIA0001GB
• The high voltage system and high voltage capacitor may remain powered for up to 10 minutes after the vehicle is shut off.
• The high voltage battery retains high voltage at all times.
• A ground fault monitor continuously monitors for high voltage leakage to the metal chassis while the vehicle is running. If a malfunction is detected, the HPCM (hybrid powertrain control module) will illuminate the hybrid system warning lamp
in the instrument cluster.
• The high voltage battery relays (SMR1 and SMR2) will automatically open to stop the electrical flow in a frontal collision that is sufficient enough to activate the supplemental restraint system (SRS).

2-6 High Voltage Circuit Shut-Off System

This vehicle is equipped with a system to shut off the current from the Li-ion battery by the following methods:
Service plug Positioned in the center area of the Li-ion battery, this plug shuts off the out-
put of high voltage when manually removed.
System main relays Controlled by the ignition switch, these relays are powered by the 12V sys-
tem and shut off high voltage from the Li-ion battery.
Emergency shut-off sys­tem
In the case of a collision (air bag deployment, etc.) or certain system malfunc­tions this system shuts off the high voltage from the Li-ion battery.

2-7 Preventing Electrical Shock

1. If it is necessary to touch any of the high voltage harnesses or components, always wear appropriate PPE (refer to
3-3.1 High Voltage System Shut-Down Procedure.
2.
To avoid the risk of electrocution, do not touch the inside of the Li-ion battery with bare hands after shutting off the high voltage system. The Li-ion battery maintains charge even though the high voltage system is shut down.
3. Cover damaged high voltage components with insulated tape.
