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 vehicle
dismantlers 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

10. After starting the EV system, carefully disconnect the negative cable and then the positive cable
() . Keep the EV system on for over twenty (20) minutes to charge the 12-volt
battery.
11. If necessary, connect the vehicle to a charging station or EVSE (Electric Vehicle Supply Equipment) to charge the high-voltage battery. The vehicle cannot be driven unless the
high-voltage battery is charged.
NOTE:
If it is not possible to turn the LEAF system ON by following this procedure, it is
recommended you contact a NISSAN certified LEAF dealer immediately.
4-2 P (Park) Position Release Procedure
If you need to release the vehicle from the P (Park) position, proceed as follows. When power switch is
turned OFF or 12-volt battery is low, LEAF automatically shifts to P position.
NOTE: This procedure requires two (2) people.
1. To start the EV system with a booster battery, refer to 4. Jump Starting (DG–33).
2.

Turn power switch ON by pushing the power switch 2 times without pressing brake pedal.
3. Confirm parking brake is applied.
4. Close all doors and press and hold the brake pedal.
5. Place the selector lever in the N (Neutral) position.
6. Remove the following 2 fuses:
• F/L 40A PBW MTR (under hood fuse and relay box)
• METER 1 10A (in the cabin fuse box)
