Components with white number in black background are high voltage components.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 volt-
age 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 Li-ion
battery to three-phase AC power and controls
motor torque (revolution) by regulating the
motor current.
Electric air condi-
tioner 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 Li-ion
battery.
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.) .
The J/B provides electric power from the Li-ion battery
to all high voltage parts of the vehicle.
12V 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.
Li-ion (Lithium ion)
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 volt-
age 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 malfunc-
tion occurs in the 12V battery.

3-1.3 Insulated Tools
When
performing work at locations where high voltage is applied (such as terminals) , use insulated tools
meeting 1,000V/300A specifications.
3-2 Vehicle Immobilization and Stabilization
If possible, immobilize the vehicle by turning the 12V system OFF and stabilize it with a wheel chock(s) .
Stabilize the vehicle with cribbing, by removing air from the tires, or utilize the Lift Airbag Equipment for
rescue. • Do not stabilize the vehicle with cribbing under the Li-ion battery.
•

To avoid electrical shock, do not put the Lift Airbag Equipment for rescue and wheel
chock(s) under the high voltage components and harnesses as shown following. =

3-3 How to Handle a Damaged Vehicle at an Accident Scene
NO
TE:
If any air bags have deployed in the following 3 situations, the high-voltage (HV) system has
been designed to automatically shut off at the time of deployment.
The Nissan LEAF high-voltage system incorporates capacitors which are energized whenever the high-
voltage system is on. If the high-voltage system is shut down (either through one of the built-in automatic
mechanisms or manually through one of the procedures explained in this FRG) , the capacitors will begin to
gradually discharge. After 5 minutes, the voltage level will have dropped below 60V, and complete
discharge requires approximately 10 minutes after high-voltage system shut down. It is within
this period of time that responders must be most cautious.
When arriving to an incident involving a Nissan LEAF, the vehicle should be approached with caution and
inspected for the level of damage. In addition to overall vehicle condition (location and severity of body
damage, air bag deployment, etc.) , the high-voltage system should be assessed specifically. The locations
of the high-voltage component parts are illustrated in this FRG. Refer to 2-1 High Voltage-Related and
12V-Related

Component Locations and Descriptions (FRG–8) . Appropriate Personal Protective Equipment
(PPE)

must always be worn when approaching a vehicle of unknown condition, as described in this FRG.
Situation 1) High voltage system intact, occupants can be accessed without extrication tools
The HV system can be shut down by following the procedures in this guide, while wearing appropriate PPE.
After HV system shut down, occupant assistance can begin immediately, and no wait period is necessary.
Situation 2) High voltage system intact, occupants cannot be accessed without extrication tools
The HV system can be shut down by following the procedure in this guide, while wearing appropriate PPE.
After HV system shut down, absolute care must be taken not to cut through or damage any HV system
wiring, battery or components within ten (10) minutes of HV system shut down, but occupant
assistance operations using extrication equipment can begin immediately. The locations of the HV
components are illustrated in this guide.
Situation 3) High-voltage (HV) system damaged
If there is any evidence that the HV system has been compromised (such as arcing/sparking, orange wiring
harnesses cut or damaged, HV component casings damaged, etc.) , the responder may still be at risk of
high voltage exposure. The vehicle must be approached with extreme caution prior to initiating any system
shut down procedures or rendering assistance to occupants. Appropriate PPE must always be worn as
described in this guide, and the ten (10) minute wait time must be observed after HV system shut
down in order to ensure the system is de-energized.
In rare situations where vehicle damage is very severe, HV system shut down procedures as described in
this guide may not work. In these instances extreme caution and appropriate risk management must be
followed to prevent shock or electrocution to the responder or occupant.

• If the charge connector is connected to the vehicle, remove it. Refer to
Removing the
Charge
Connector (FRG–17) .
• 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 (FRG–6) 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.
FRG–17

SRS Air Bag System Components Location
Avoid
cutting air bag system parts. However, the vehicle can be cut (except inflators) under the following
conditions: • The front, side and curtain air bags have deployed.
• At least three (3) minutes have passed after the 12V battery negative (-) cable has beendisconnected and the high voltage system has been shut down. = Inflators (Peel back plastic trim parts prior to cutting


operations to confirm exact inflator location.)
