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.

deployed. – Certain rear collisions. – Certain EV system malfunctions.

This lamp is on when another red warning lamp is displayed in the instrument cluster or a warning is displayed on the dot matrix LCD.

Master Warning Lamp (YELLOW)

This lamp is on when:

• Li-ion battery is getting low on charge.

• A yellow warning lamp is displayed in the instrument cluster or a message is displayed on the dot matrix LCD.

*1: When this lamp is ON, the ready lamp will turn OFF.

Li-ion battery voltage 403.2V Number of Li-ion battery modules in the pack 48 Li-ion battery dimensions 61.8 x 46.8 x 10.4 in. (1570.5 x 1188 x 264.9 mm) Li-ion battery weight 648 lbs (294 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.

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 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 system

Charging connector Some of the high voltage components are activated during charging. Remove

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.

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 wear appropriate 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 Procedure.

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 will 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 wearing appropriate PPE.

• If it is necessary to touch any of the high voltage harnesses or components you must wear appropriate PPE to avoid electrical shock. Shut down the high voltage system by following the steps outlined in 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, charging indicator or air conditioning remote timer 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.
