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.

AAYIA0044GB7

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 3-2 Preparation Items) and shut
off

the high voltage system by referring to 3-3 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.

3. Preparation for Dismantling
• Failure to properly shut down the high voltage electrical system before the
Dismantling 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 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 it becomes necessary for the dismantler to leave the vehicle, place a “DANGER” sign
(for
example, refer to 4-3 Storing the Vehicle) on the vehicle to alert other people that the
vehicle

contains a high voltage battery.
• 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.
3-1 Discharging Procedures Do not perform this procedure if the battery is damaged. If you are unsure of battery
damage,

use extreme caution and wear appropriate Personal Protective Equipment (PPE) .
Li-ion battery discharging must take place before dismantling. Sufficient discharging can be achieved by
following these steps. 1. Place the selector lever into the Park (P) position
2. Apply the parking brake.
3. Set wheel chocks to ensure the vehicle is completely immobilized.
13

4. Apply foot brake and press the ignition switch to turn the system ON. Confirm READY
indicator in instrument cluster turns ON.
5. Check Li-ion battery available charge gauge: a. If remaining energy (1) shows higher than half full (7 of 12 gauge lines lit up) , continue to next step.
b. If remaining energy (2) shows lower than half full (6 of 12 gauge lines lit up) , discharging is not needed.
6. Turn ON electric devices such as headlamps, cabin heater (set to the highest temperature and maximum fan speed; do not use AUTO A/C setting) , navigation system and rear window defogger
to discharge the Li-ion battery. Allow approximately 30 minutes for each line on the available
charge gauge to drop. Discharge is complete when the available charge gauge drops to lower
than half full (6 of 12 gauge lines lit up) .
7. Press the power switch to turn the system OFF. LOCK Acc

3-3 High Voltage System Shut-Down Procedures
Once
the high voltage battery is properly discharged, any of the following procedures can shut down and
isolate the high voltage system. The dismantling operation can only begin after shutting down the high
voltage system. If the vehicle is heavily damaged, for example the Li-ion battery is deformed, broken or
cracked, appropriate Personal Protective Equipment (PPE) must always be used and the Li-ion battery and
high voltage components must not be touched. •
Failure to properly shut down the high voltage system before the dismantling
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) .
•
When contact with high voltage components or high voltage harnesses is unavoidable,
or when there is risk of such contact, you must always wear appropriate PPE. • If the charge connector is connected to the vehicle, remove it. Refer to
3-3.1 Removing
the

Charge Connector .
• The vehicle contains parts that contain powerful magnets. If a person who is wearing
a

pacemaker or other medical device is close to these parts, the medical device may be
affected by the magnets. Such persons must not perform work on the vehicle.
• Be sure to verify that the READY indicator is off and the high voltage system is
stopped.
•

After the high voltage system is shut down, please wait at least ten (10) minutes for
complete discharge of the high voltage capacitor. While waiting, do not operate any vehicle
functions.
• After shutting down the high voltage system and removing the 12V battery negative (-) terminal, wait at least three (3) minutes to discharge the air bag capacitor. Even though the
12V battery negative (-) is disconnected, the Supplemental Restraint System (SRS) air bag
maintains voltage at least three (3) minutes. During this time, there is a possibility of
sudden SRS air bag inflation due to harness short circuit or damage and it may cause
serious injuries.
• Always shut down the high voltage system before disconnecting the 12V battery. Not doing so may result in serious injury or death from electrical shock.
• The 12V system will remain active even after the 12V battery negative (-) terminal is removed while the high voltage system is active. The high voltage system is active during
any of the following conditions:
– charging indicator is turned ON
– READY indicator is turned ON
Refer to 1-1.2 Interior Component Location
for location of these indicators. This is because
DC/DC

converter will not shut down and power will be supplied to the 12V system and
high voltage system continuously.

4. Jump Starting
T
o start the EV system with a booster battery, the instructions and precautions below must be followed. If done incorrectly, jump starting can lead to a 12V battery explosion, resulting in severe
personal

injury or death. It could also damage your vehicle.
Discharged 12V battery may cause the following issues: • The instrument cluster cannot be displayed while the power switch is turned ON. The start-upsound is not audible. (The electric car system cannot start.)
• The Li-ion battery cannot be charged.
• The vehicle cannot be shifted out of PARK normally. • To avoid electrical shock, the high voltage Li-ion battery CANNOT be jump started.
•

Explosive hydrogen gas is always present in the vicinity of the 12V battery. Keep all
sparks and flames away from the 12V battery.
• Do not allow battery fluid to come into contact with eyes, skin, clothing or painted surfaces. Battery fluid is a corrosive sulfuric acid solution that can cause severe burns. If
the fluid comes into contact with anything, immediately flush the contacted area with
water.
• The booster battery must be rated at 12 volts. Use of an improperly rated battery can damage the vehicle.
• Whenever working on or near a 12V battery, always wear suitable eye protectors (for example, goggles or industrial safety spectacles) and remove rings, metal bands, or any
other jewelry. Do not lean over the 12V battery when jump starting.
• Do not attempt to jump start a frozen battery. It could explode and cause serious injury.
• LEAF is equipped with an automatic cooling fan. It could come on at any time. Keep hands and other objects away from it.
• Always follow the jump starting instructions below. Failure to do so could result in damage to the DC/DC converter and cause personal injury. • Do not use LEAF to jump start another vehicle.
•

Do not attempt to perform a jump start on the 12V battery at the same time that the
Li-ion battery is being charged. Doing so may damage the vehicle or charging
equipment and could cause an injury.
