charging NISSAN LEAF 2013 1.G First Responders Guide

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.

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.

• Failure to properly shut down the high voltage 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) .
• 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
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.
NOTE:
The high voltage full discharge takes ten (10) minutes, but after five (5) minutes the voltage
has dropped below 60V.
• 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.
