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-voltage
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 high-voltage
battery to three-phase AC power and controls
motor torque (revolution) by regulating the motor
current.
Electric air
conditioner
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
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.

2-1.1 High-Voltage Battery Pack Specifications
High-voltage battery voltage
360V nominal
(240V - 398.4V usable range)
Number of high-voltage battery modules in the pack 48
High-voltage battery dimensions 60.91 x 46.77 x 10.39 in. (1547 x 1188 x 264 mm)
High-voltage battery weight US: 648 lbs (294 kg)
Canada: 653 lbs (296 kg)
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.

3. Roadside Assistance Response Steps
• NEVER assume the LEAF is shut OFF simply because it is quiet.
• If the vehicle is damaged and you are not sure about the condition of the electric
vehicle system, contact first responders immediately. If the vehicle is damaged, the
high-voltage system should be shut down by first responders while following the
procedures in the First Responders Guide and while wearing appropriate Personal
Protective Equipment (PPE) .
• 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.
3-1 Indications the High-voltage System is ON 1. If the READY indicator is ON, the high-voltage system is active.
2.

The high-voltage system is active if any charge indicator
is ON (blue LEDs on top of the instrument panel) .
Before disconnecting the 12-volt battery terminal, if necessary, lower the windows, unlock the doors, and
open the rear hatch as required. Once 12-volt battery is disconnected, power controls will not operate. AAYIA0155ZZ

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 wooden blocks or by removing air from the tires. • Do not stabilize the vehicle with wooden blocks under the high-voltage battery.
•

To avoid electrical shock, do not put wooden blocks or wheel chock(s) under the
high-voltage components and harnesses as shown following. AAYIA0191GB
RAG–13

3-3 Turning OFF the Power Switch
1. Check the READY indicator status. If it is ON, the high-voltage system is active.
2.

Press the power switch once to turn OFF the high-
voltage system. Then verify whether the READY indicator is OFF.
3.
If possible, keep the Nissan Intelligent Key® at least
5 meters (16 feet) away from the vehicle to prevent
accidentally turning ON the EV system while the
roadside assistance is in progress. AAYIA0091ZZ

3-4 Water Submersion
Damage level of submerged vehicle may not be apparent. Handling a submerged
vehicle without appropriate Personal Protective Equipment (PPE) will result in serious
injury or death from electrical shock. • The power switch of the submerged vehicle must be turned OFF first, if possible.
Then
the vehicle must be completely out of the water and drained to avoid electrical
shock.
• If the vehicle is in the water, to avoid electrical shock NEVER touch the high-
voltage
components, harnesses or service plug. PPE must always be worn when
touching or working on high-voltage components.
Only first responders wearing appropriate Personal Protective Equipment (PPE) should shut down
the vehicle. After shut down, standard towing/recovery procedures can be used.
Refer to 4-3 Towing (RAG–22) .
3-5

Vehicle Fire • Always utilize full Personal Protective Equipment (PPE) and self-contained breathing
apparatus
during fire fighting operations. Smoke from a LEAF vehicle fire is similar to
smoke from a conventional vehicle fire.
• In the case of extinguishing a fire with water, large amounts of water from a fire hydrant (if possible) must be used. DO NOT extinguish fire with a small amount of
water. In the event of a small fire, a Type ABC fire extinguisher may be used for an electrical fire
caused

by wiring harnesses, electrical components, etc. or oil fire.
In case of vehicle fire, contact fire department immediately and extinguish the fire if possible. If you must
walk away from the vehicle, notify an appropriate responder or a rescue person of the fact that the vehicle
is an electric car and contains a high-voltage system and warn all others.

3-6 High-voltage Battery Damage and Fluid Leaks
The high-voltage battery contains electrolyte solution. To avoid exposure to electrolyte
solution
and serious personal injury, always wear appropriate solvent resistant Personal
Protective Equipment (PPE) and read the following precautions:
• Electrolyte solution is a skin irritant.
• Electrolyte solution is an eye irritant – If contact with eyes, rinse with plenty of water and see a doctor immediately.
• If electrolyte leak occurs, wear appropriate solvent resistant PPE and use a dry cloth to clean up the spilled electrolyte. Be sure to adequately ventilate the area.
• Electrolyte solution is highly flammable
• Electrolyte liquid or fumes that have come into contact with water vapors in the air will create an oxidized substance. This substance may irritate skin and eyes. In these
cases, rinse with plenty of water and see a doctor immediately.
• Electrolyte fumes (when inhaled) can cause respiratory irritation and acute intoxication. Move to fresh air and wash mouth with water. See a doctor immediately.
In cases of battery case breach or electrolyte leakage, contact the fire department immediately. If you must
walk away from the vehicle, notify an appropriate responder of the fact that the vehicle is an electric car and
contains a high-voltage system and warn all others.
High-voltage Battery Electrolyte Solution Characteristics: • Clear in color
• Sweet odor
• Similar viscosity to water
• Since the high-voltage battery is made up of many small sealed battery modules, electrolyte solutionleakage should be minimal.
NOTE:
Other fluids in the vehicle are the same as those in a conventional internal combustion
vehicle.
