1. About The Nissan LEAF®
This
vehicle uses two types of batteries. One is a 12V battery that is the same as the battery in vehicles
powered by internal combustion engines, and the other is the Lithium-ion (Li-ion) battery (high voltage) for
the traction motor which propels the vehicle. The Li-ion battery is encased in steel and mounted underneath
the vehicle.
The vehicle must be plugged-in in order for the Li-ion battery to be recharged. 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. This vehicle is considered to be
an environmentally friendly vehicle because it does not emit exhaust gases.

1-2 Vehicle Identification Number (VIN) Layout
The
vehicle identification number can be located as follows:
Example VIN : 1N4A Z0CPZDC055126
The LEAF is identified by the 5
thalphanumeric character: Z
Z = Electric vehicle
1. VIN plate (visible through windshield) 2. Vehicle certification plate (lower center pillar)
1-3 Warning and Indicator Lamp Information
The following warning and indicator lamps are located in the instrument cluster. Lamp Name
Icon Description
READ

Y Indicator This lamp is on when the EV system is powered up and the
vehicle

is ready to drive.
EV System Warning Lamp *1 • Malfunction has occurred in the EV system and/or
•

Emergency shut-off system has been activated. The shut-
off system activates in the following conditions:
– Front and side collisions in which the air bags are deployed.
– Certain rear collisions.
– Certain EV system malfunctions.
Master Warning Lamp (RED) This lamp is on when another red warning lamp is displayed in
the

instrument cluster or a warning is displayed on the dot
matrix LCD.
Master Warning Lamp
(YELLOW) This lamp is on when:
•

Li-ion battery is getting low on charge.
• A yellow warning lamp is displayed in the instrument cluster or a message is displayed on the dot matrix LCD.
*1: When this lamp is ON, the ready lamp will turn OFF. 1

Components with white number in black background are high voltage components.No. Component
LocationDescription
a Charge

port Under hood Connecting port for EVSE (Electric Vehicle
Supply Equipment) . Two ports are available:
Normal charge and quick charge (if so
equipped) .
b High voltage
cables Under hood and
undercarriage Orange-colored power cables carry high volt-
age current between each of the high voltage
components.
c Traction Motor Under hood Converts three-phase AC power to drive
power (torque) which propels the vehicle.
Inverter Under hood 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.
Electric air condi-
tioner compressor Under hood
Air conditioner compressor
Power Distribution
Module (PDM)
• On Board Charger
• DC/DC Converter
• High voltage junction box (J/B) Under hood
The PDM includes an On Board Charger, DC/DC
converter and high voltage junction box (J/B) .
The On Board Charger converts single-phase AC
power from a home power outlet to DC power and
increases the voltage in order to charge the Li-ion
battery.
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.) .
The J/B provides electric power from the Li-ion battery
to all high voltage parts of the vehicle.
d 12V Battery Under hood A lead-acid battery that supplies power to the low
voltage devices.
e Cabin heater Interior (This unit is
installed behind the
instrument panel) This is the electric heat source for the cabin
heater. It heats the interior of the vehicle.
f Li-ion (Lithium ion)
battery Undercarriage Stores and outputs DC power (Maximum voltage
398.4V) needed to propel the vehicle.
g High voltage battery
service disconnect Rear seat floor Isolates the battery from the rest of the high volt-
age electrical system.
h Brake power supply
backup unit Cargo area (This unit
is installed behind a
trim panel to prevent
access) Power supply backup unit for the brake system. It
supplies power to the brake system if a malfunc-
tion occurs in the 12V battery.

2-1.1 Li-ion Battery Pack Specifications
Li-ion battery voltage
360V nominal
(240V - 398.4V usable range)
Number of Li-ion battery modules in the pack 48
Li-ion battery dimensions 60.91 x 46.77 x 10.39 in. (1547 x 1188 x 264 mm)
Li-ion battery weight 606 lbs (275 kg)
2-2 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 emergency
responders from high voltage electrical shock.
Identification The high voltage components are labeled “WARNING” similar to label
shown below. All high voltage harnesses are coated in orange.
2-2.1 Warning Label AAYIA0147ZZ

2-3 High Voltage Circuit Shut-Off System
The
high voltage can be shut off by the following methods: Service plug
Positioned in the center area of the Li-ion battery, this shuts off output high
voltage
when manually removed.
System main relay Controlled by the power switch, this relay, which is controlled by the 12V system, shuts off the high voltage from the Li-ion battery.
Emergency shut-off sys-
tem In the case of a collision (front and side collisions in which the air bags are
deployed, certain rear collisions) or certain system malfunctions this system
may shut off the high voltage from the Li-ion battery.
Charging connector Some of the high voltage components are activated during charging. Remove the charging connector to deactivate these components.
2-4 Preventing Electrical Shock 1. If it is necessary to touch any of the high voltage harnesses or components, you must alwayswear appropriate Personal Protective Equipment (PPE) (refer to 3-1 Preparation Items) and shut
off

the high voltage system by referring to 3-3.1 High Voltage System Shut-Down Procedures.
2.

To avoid the risk of electrocution, do not touch the inside of the Li-ion battery unless appropriate
PPE is worn even after shutting off the high voltage system. The Li-ion battery maintains charge
even though the high voltage system is shut down.
3. Cover any damaged high voltage components with insulated tape.
2-5 Emergency Medical Equipment
The high voltage system should not interfere with emergency medical equipment which must be used in or
near the vehicle at an accident scene.

3. Emergency Response Steps
• Failure to properly shut down the high voltage electrical system before the
Emergency Response Procedures are performed will result in serious injury or death
from electrical shock. To prevent serious injury or death, DO NOT touch high voltage
harnesses or components without always wearing appropriate Personal Protective
Equipment (PPE) .
• If it is necessary to touch any of the high voltage harnesses or components you
must
always wear appropriate PPE to avoid electrical shock. Shut down the high
voltage system by following the steps outlined in 3-3.1 High Voltage System Shut-
Down

Procedures. Wait at least ten (10) minutes for complete discharge of the high
voltage

capacitor after the high voltage system has been shut down. • NEVER assume the LEAF is shut OFF simply because it is quiet.
• If the READY indicator or charging indicator are ON, the high voltage system is
active.
• If possible, be sure to verify that the READY indicator on the instrument cluster
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.
