1. About The Nissan LEAF®
This
vehicle 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, and the other is the high-voltage battery for the traction motor
which propels the vehicle. The high-voltage battery is encased in steel and mounted underneath the vehicle.
The vehicle must be plugged-in in order for the high-voltage battery to be recharged. 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. 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 Z0CPXHC053500
The LEAF is identified by the 5
thalphanumeric character: Z
Z = Electric vehicle
1. VIN plate (visible through windshield) 2. Vehicle certification label (lower center pillar)
1-3 Warning and Indicator Lamp Information

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.

No. Component
LocationDescription
Charge
port Under hood Connecting port for EVSE (Electric Vehicle
Supply Equipment) . Two ports are available:
Normal charge and quick charge (if so equipped) .
High-voltage cables Under hood and
undercarriage Orange-colored power cables carry high-voltage
current between each of the high-voltage
components.
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 high-voltage
battery to three-phase AC power and controls
motor torque (revolution) by regulating the motor
current.
Electric air
conditioner
compressor Under hood
Air conditioner compressor
Power Delivery
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
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.) .
The J/B provides electric power from the high-
voltage battery to all high-voltage parts of the
vehicle.
12-volt Battery Under hood A lead-acid battery that supplies power to the
low voltage devices.
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.
High-voltage battery Undercarriage Stores and outputs DC power (Maximum voltage
398.4V) needed to propel the vehicle.
High-voltage battery
service disconnect Rear seat floor Isolates the battery from the rest of the high-
voltage electrical system.
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
malfunction occurs in the 12-volt battery.

2-1.1 High-Voltage Battery Pack Specifications
High-voltage battery voltage
360V nominal
(240V - 398.4V usable range)
Number of high-voltage battery modules in the pack 48
High-voltage battery dimensions 60.91 x 46.77 x 10.39 in. (1547 x 1188 x 264 mm)
High-voltage battery weight US: 648 lbs (294 kg)
Canada: 653 lbs (296 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
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 high-voltage battery, this shuts off output
high-voltage
when manually removed.
System main relay (located
in high-voltage battery) Controlled by the power switch, this relay, which is controlled by the 12-volt
system, shuts off the high-voltage from the high-voltage battery.
Emergency shut-off
system 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
is designed to shut off the high-voltage from the high-voltage battery.
Charging connector Some of the high-voltage components are activated during charging. Remove the charging connector to deactivate these components. AAYIA0147ZZ

2-4 Preventing Electrical Shock
1. If it is necessary to touch any of the high-voltage harnesses or components, you must always
wear appropriate Personal Protective Equipment (PPE)
(refer to 3-1 Preparation Items (FRG–13) ) and shut off the high-voltage system by referring
to 3-3.1 High-voltage System Shut-Down Procedures (FRG–17).
2.

To avoid the risk of electrocution, NEVER touch the inside of the high-voltage battery unless
appropriate PPE is worn even after shutting off the high-voltage system. The high-voltage 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.
