2019 NISSAN LEAF battery

The Li-ion battery warmer uses electrical
power from an external source when a
charger is connected to the vehicle. The
Li-ion battery warmer uses electrical
power from the Li-ion battery when the
charger is not connected to the vehicle.
NOTE:
•Connect the charger to the vehicle and
place the power switch in the OFF posi-
tion when parking the vehicle if tem-
peratures may go below -1°F (-17°C). This
provides external power to the Li-ion
battery warmer when it operates and
does not discharge the Li-ion battery.
• The charging status indicator lights illu-
minate in a specific pattern when the
Li-ion battery warmer operates. The
charging status indicator lights use the
same pattern to indicate 12-volt battery
charging, Climate Ctrl. Timer operation
or Remote Climate Control operation
(models with Navigation System). The
charging status indicator lights do not
change if the Li-ion battery warmer op-
erates at the same time as the above
features. For additional information, re- fer to “Charging status indicator lights”
in the “Charging” section of this manual.
• The Li-ion battery warmer uses Li-ion
battery power to operate, even if the
vehicle is connected to a charger when:
– The vehicle's power switch is in the ON position.
– There is no electrical power being supplied to the charging equipment.
• When the Li-ion battery warmer is al-
ready in operation using an external
power source, it will continue to use the
external power even if the power switch
is placed in the ON position.
• Vehicle driving range is reduced if the
Li-ion battery warmer operates (Li-ion
battery temperature approximately
-1°F (-17°C) or colder) while driving the
vehicle. You may need to charge the Li-
ion battery sooner than in warmer tem-
peratures.
• The Li-ion battery requires more time to
charge when the Li-ion battery warmer
operates. •
The predicted charging time displayed
on the meter and navigation system (if
so equipped) increases when the Li-ion
battery warmer operates.
• Climate control performance is reduced
when using the Climate Ctrl. Timer or
Remote Climate Control (models with
Navigation System) while the Li-ion bat-
tery warmer operates.
• The Li-ion battery may not charge to
the expected level using the charging
timer while the Li-ion battery warmer
operates.
For models with 62 kWh battery
CAUTION
The Li-ion battery warmer does not
operate if the normal charger is not
connected to the vehicle. To help pre-
vent the Li-ion battery from freezing,
do not leave the vehicle in an environ-
ment if temperatures may go below
-4°F (-20°C) unless the vehicle is con-
nected to a charger.
EV-6EV Overview

The Li-ion battery warmer helps to prevent
the Li-ion battery from freezing when the
temperature is cold. The Li-ion battery
warmer automatically turns on when the
Li-ion battery temperature is approxi-
mately -4°F (-20°C) or colder and outside
temperature is approximately -11°F (-24°C)
or colder. The Li-ion battery warmer auto-
matically turns off when the Li-ion battery
temperature is approximately 0°F (-18°C) or
higher, or outside temperature is approxi-
mately -8°F (-22°C) or higher.
The Li-ion battery warmer operates when
the normal charger is connected to the
vehicle, and it automatically uses electrical
power from either the external source or
from the Li-ion battery.
NOTE:
•Connect the charger to the vehicle and
place the power switch in the OFF posi-
tion when parking the vehicle if tem-
peratures may go below -4°F (-20°C).
The Li-ion battery warmer automati-
cally uses electrical power from either
the external source or from the Li-ion
battery, based on the amount of re-
maining Li-ion battery. •
The charging status indicator lights illu-
minate in a specific pattern when the
Li-ion battery warmer operates. The
charging status indicator lights use the
same pattern to indicate 12–volt bat-
tery charging, Climate Ctrl. Timer opera-
tion or Remote Climate Control opera-
tion (models with Navigation System).
The charging status indicator lights do
not change if the Li-ion battery warmer
operates at the same time as the above
features. For additional information, re-
fer to “Charging status indicator lights”
in the “Charging” section of this manual.
• The automatic climate control auto-
matically turns on when the Li-ion bat-
tery warmer uses electrical power from
the Li-ion battery. This is not a malfunc-
tion. When the Li-ion battery warmer
operates, the temperature inside the
vehicle may be warmed up.
• The Li-ion battery will be automatically
charged when the Li-ion battery
warmer uses electrical power from an
extended source. When outside tem-
perature goes below -4°F (-20°C) for
many days, frequent Li-ion battery
warmer operation may occur, and more electric power will be charged from an
external source. Do not connect the
normal charger to the vehicle if you do
not want to turn on the Li-ion battery
warmer. In this case, do not leave the
vehicle in an environment if tempera-
tures may go below -4°F (-20°C).
• When the Li-ion battery warmer is al-
ready in operation using an external
source, it will continue to use the exter-
nal power even if the power switch is
placed in the ON position.
• The Li-ion battery warmer will stop if
the power switch is placed in the ON
position while the Li-ion battery
warmer is using electrical power from
the Li-ion battery. To turn on the Li-ion
battery warmer again, place the power
switch in the OFF position.
• The Li-ion battery warmer will stop if
the charging connector is removed
from the normal charger while the Li-
ion battery warmer is operating. To turn
on the Li-ion battery warmer again,
connect the charging connector to the
vehicle. The Li-ion battery warmer will
operate again af ter about 1 hour.
EV OverviewEV-7

•The Li-ion battery warmer will stop if
the charging connector of the quick
charger is connected to the vehicle
while the Li-ion battery warmer is oper-
ating. To turn on the Li-ion battery
warmer again, remove the charging
connector of the quick charger from the
vehicle.
• The Li-ion battery requires more time to
charge to the expected level when the
Li-ion battery warmer operates.
• The predicted charging time displayed
on the meter increases when the Li-ion
battery warmer uses electrical power
from the Li-ion battery.
• The Climate Ctrl. Timer or Remote Cli-
mate Control (models with Navigation
System) does not turn on while the
Li-ion battery warmer operates. This is
not a malfunction. •
The charging timer or remote charge
(models with Navigation System) does
not turn on while the Li-ion battery
warmer operates. This is not a malfunc-
tion.
• The Li-ion battery may not be charged
to the expected level using the charging
timer while the Li-ion battery warmer
operates.
• If the Li-ion battery warmer automati-
cally stops because of the Li-ion battery
temperature or outside temperature
change, charging will continue until the
Li-ion battery is fully charged.
EV-8EV Overview

HIGH-VOLTAGE COMPONENTS
WARNING
• The EV system uses high voltage up to approximately DC 400 volt. The
system can be hot during and af ter
starting and when the vehicle is shut
off. Be careful of both the high volt-
age and the high temperature. Fol-
low the warning labels that are at-
tached to the vehicle.
• Never disassemble, remove or re- place high-voltage parts and cables
as well as their connectors because
they can cause severe burns or elec-
tric shock that may result in serious
injury or death. High-voltage cables
are colored orange. The vehicle high
voltage system has no user service-
able parts. It is recommended that
you take your vehicle to a NISSAN
certified LEAF dealer for any neces-
sary maintenance. 1. Traction motor and reduction gear
2. Traction motor inverter
3. Power delivery module (PDM) (Charger,
DC/DC converter, junction box) 4. High-voltage wire harnesses (colored
orange)
5. Li-ion battery

HIGH VOLTAGE PRECAUTIONS
EV OverviewEV-9

WARNING
In case of a collision:
• If your vehicle is drivable, pull your vehicle off the road, push the P
(Park) position switch on the shif t
lever, apply the parking brake and
turn the EV system off.
• Check your vehicle to see if there are exposed high-voltage parts or
cables. For their locations, refer to
“High voltage components” in this
section. To avoid personal injury,
never touch high-voltage wiring,
connectors, and other high-voltage
parts, such as inverter unit and Li-
ion battery. An electric shock may
occur if exposed electric wires are
visible when viewed from inside or
outside of your vehicle. Therefore,
never touch exposed electric wires.
• If the vehicle receives a strong im- pact to the floor while driving, stop
the vehicle in a safe location and
check the floor.
• Leaks or damage to the Li-ion bat- tery may result in a fire. If you dis-
cover them, contact emergency ser-
vices immediately. Since the fluid
leak may be lithium manganate from the Li-ion battery, never touch
the fluid leak inside or outside the
vehicle. If the fluid contacts your
skin or eyes, wash it off immediately
with a large amount of water and
receive immediate medical atten-
tion to help avoid serious injury.
• If a fire occurs in the EV, leave the vehicle as soon as possible. Only use
a type ABC, BC or C fire extinguisher
that is meant for use on electrical
fires. Using a small amount of water
or the incorrect fire extinguisher can
result in serious injury or death from
electrical shock.
• If your vehicle needs to be towed, do it with the front wheels raised. If the
front wheels are on the ground
when towing, the traction motor
may generate electricity. This may
damage the components of the EV
system and cause a fire.
• If you are not able to safely assess the vehicle due to vehicle damage,
do not touch the vehicle. Leave the
vehicle and contact emergency ser-
vices. Advise first responders that
this is an electric vehicle. • In the event of an accident that re-
quires body repair and painting, the
Li-ion battery pack and high voltage
parts such as the inverter, including
the wire harness, should be re-
moved prior to painting. It is recom-
mended that you visit a NISSAN cer-
tified LEAF dealer for this service.
Li-ion battery packs exposed to heat
in the paint booth will experience
capacity loss. Damaged Li-ion bat-
tery packs may also pose safety
risks to untrained mechanics and re-
pair personnel.
EMERGENCY SHUT-OFF SYSTEM
The emergency shut-off system is acti-
vated and the high-voltage system auto-
matically turns off in the following condi-
tions:
- Front and side collisions in which the air
bags are deployed.
- Certain rear collisions.
- Certain EV system malfunctions.
ROAD ACCIDENT PRECAUTIONS
EV-10EV Overview

For the above collisions and certain other
EV system malfunctions, the READY to
Drive indicator light will turn off. For addi-
tional information, refer to “Warning lights,
indicator lights and audible reminders” in
the “Instruments and controls” section of
this manual.
The emergency shut-off activates for the
above collisions to minimize risk of an
event that could cause injury or an acci-
dent. If the emergency shut-off system ac-
tivates, the EV system may not be switched
to the READY to Drive position; it is recom-
mended that you visit a NISSAN certified
LEAF dealer. Even if the power switch is
switched to the READY to Drive position, the
system may shut-off suddenly. Therefore,
drive cautiously to the nearest certified
repair facility; it is recommended that you
visit a NISSAN certified LEAF dealer for ser-
vice.
WARNING
• Pay special attention to pedestrians. Because there is no engine noise,
pedestrians may not know the ve-
hicle is approaching, moving or
about to move, and may step into
the path of vehicle travel.
• When leaving the vehicle, be sure to turn off the EV system.
• Be sure to push the P (Park) position switch on the shif t lever and apply
the parking brake when parking be-
cause the vehicle can move when
the READY to Drive indicator light is
ON. When the READY to Drive indica-
tor light is ON, do not leave your ve-
hicle in a shif t position other than
the P (Park) position.
• Keep the brake pedal depressed un- til you are ready to drive. When the
vehicle is in the D (Drive) position, B
or R (Reverse) position, if you release
the brake pedal and do not depress
the accelerator, the vehicle will creep
and may start abruptly. This may
cause serious injury or death.
NOTE:
•The vehicle cannot run with a discharged
Li-ion battery. Repeated acceleration
consumes more power from the Li-ion
battery than driving at a steady speed.
•This vehicle is equipped with a regen-
erative brake system. The primary pur-
pose of the regenerative brake system
is to provide some power to recharge
the Li-ion battery and extend driving
range. A secondary benefit is “engine
braking” that operates based on Li-ion
battery conditions.
• In the D (Drive) position, when the accel-
erator pedal is released, the regenera-
tive brake system provides some decel-
eration.
• When you put the shif t lever in the B
mode and take your foot off the accel-
erator pedal, more regenerative brake is
applied than in the D (Drive) position.
EV CHARACTERISTICS
EV OverviewEV-11

•Less deceleration is provided by the re-
generative brake system when the Li-
ion battery is fully charged. The regen-
erative brake is automatically reduced
when the Li-ion battery is fully charged
to prevent the Li-ion battery from be-
coming overcharged. The regenerative
brake is also automatically reduced
when the battery temperature is high/
low (indicated by the red/blue zones on
the Li-ion battery temperature gauge)
to prevent Li-ion battery damage.
• The brake pedal should be used to slow
or stop the vehicle depending on traffic
or road conditions. The vehicle brakes
are not affected by the regenerative
brake system operation.NOISE AND VIBRATION
You might experience the following noise
or vibration as a normal characteristic of
this vehicle:
• Traction motor noise from the motor
compartment.
• Water pump and radiator fan noise while charging.
• Compressor and radiator fan noise when the Climate Ctrl. Timer or remote climate
control (models with Navigation System)
is used.
• Relay operation noise and vibration at start-up and shut-down of the EV system
(power switch placed in the ON and OFF
position).
• Approaching Vehicle Sound for Pedestri- ans (VSP). This section provides a brief explanation
for the most important LEAF functions. For
additional information, refer to the specific
sections of this manual for detailed expla-
nations of the vehicle features and opera-
tion.
CHARGING THE LI-ION BATTERY
WARNING
The EV system uses a high voltage cur-
rent. Failure to follow the proper han-
dling instructions may cause serious
injury or death. Be sure to read the
“Charging” section and follow the pro-
cedures and guidelines described.
