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.

deployed.
– Certain rear collisions.
– Certain EV system malfunctions.
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.

a Traction Motor Under hood Converts three-phase AC power to drive
power (torque) which propels the vehicle.
b DC/DC Converter
– High voltage
junction box
Under hood This component includes a DC/DC converter
and high voltage junction box (J/B). The junction box provides electric power from the Li-ion
battery to all high voltage parts of 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.).
c 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.
d Electric air condi-

e Cabin heater Under hood This is the electric heat source for the cabin
heater. It heats the interior of the vehicle.
f Charge port Under hood Connecting port for EVSE (Electric Vehicle
Supply Equipment). Two ports are available:
Normal charge and quick charge (if so
equipped).
g 12V Battery Under hood A lead-acid battery that supplies power to the
low voltage devices.

2-1.1 Li-ion Battery Pack Specifications
Li-ion battery voltage 403.2V
Number of Li-ion battery modules in the pack 48
Li-ion battery dimensions 61.8 x 46.8 x 10.4 in. (1570.5 x 1188 x 264.9 mm)
Li-ion battery weight 648 lbs (294 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
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 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 system
Charging connector Some of the high voltage components are activated during charging. Remove
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.
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 always
wear appropriate PPE (refer to 3-1 Preparation Items) and shut off the high voltage system by
referring
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.
