1. About The Nissan LEAF®
This
vehicle uses two types of batteries. One is a 12-volt battery that is the same as the battery in vehicles
powered by internal combustion engines, and the other is the high-voltage battery for the traction motor
which propels the vehicle. The high-voltage battery is encased in steel and mounted underneath the vehicle.
The vehicle must be plugged-in in order for the high-voltage battery to be recharged. Additionally, the
vehicle system can recharge the high-voltage 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.

1-2 Vehicle Identification Number (VIN) Layout
The
vehicle identification number can be located as follows: Example VIN : 1N4A Z0CPXHC053500
The LEAF is identified by the 5
thalphanumeric character: Z
Z = Electric vehicle
1. VIN plate (visible through windshield) 2. Vehicle certification label (lower center pillar)

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
high-voltage battery.
The DC/DC converter reduces the voltage of the
high-voltage battery to provide power to the
12-volt battery in order to operate the vehicle’s
electric components (headlights, audio system,
etc.) .
The J/B provides electric power from the high-
voltage battery to all high-voltage parts of the
vehicle.
12-volt 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.
High-voltage 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-
voltage 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
malfunction occurs in the 12-volt battery.

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 from high-voltage electrical shock.
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 high-voltage battery, this shuts off output
high-voltage
when manually removed.
System main relay (located
in high-voltage battery) Controlled by the power switch, this relay, which is controlled by the 12-volt
system, shuts off the high-voltage from the high-voltage battery.
Emergency shut-off
system 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
is designed to shut off the high-voltage from the high-voltage battery.
Charging connector Some of the high-voltage components are activated during charging. Remove the charging connector to deactivate these components. AAYIA0147ZZ

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 Personal Protective Equipment (PPE)
(refer to 3-1 Preparation Items (FRG–13) ) and shut off the high-voltage system by referring
to 3-3.1 High-voltage System Shut-Down Procedures (FRG–17).
2.

To avoid the risk of electrocution, NEVER touch the inside of the high-voltage battery unless
appropriate PPE is worn even after shutting off the high-voltage system. The high-voltage 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.

rescue. • Do not stabilize the vehicle with cribbing under the high-voltage 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. AAYIA0191GB
FRG–15

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
12-volt-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.
