battery NISSAN LEAF 2017 1.G Repair Manual

The power meter also indicates if the power
provided to the motor is limited or if regenerative
braking is limited. When power or regenerative
braking is limited, the circles on the display
change from a double circle to a single circle
2.
Regenerative braking is automatically reduced
when the Li-ion battery is fully charged to prevent
the Li-ion battery from becoming overcharged.
Regenerative braking is also automatically re-
duced when the Li-ion battery temperature is
high/low (indicated by the red/blue zones on the
Li-ion battery temperature gauge) to prevent Li-
ion battery damage.
The more regenerative braking is reduced, the
more double circles change to single circles.
If the Li-ion battery charge is low, power provided
to the traction motor is reduced. Motor output is
also limited if the Li-ion battery temperature is
high/low (indicated by the red/blue zones on the
Li-ion battery temperature gauge) or the Li-ion
battery charge level is low.
The more power provided to the traction motor is
reduced, the more double circles change to
single circles.
DRIVING RANGE
The driving range1(miles or km) provides an
estimated distance that the vehicle can be driven
before recharging is necessary. The driving range
is constantly being calculated, based on the
amount of available Li-ion battery charge and the
actual power consumption average.
NOTE:
• The driving range display will flash when
the low battery charge warning light illu-
minates. Additionally, if you continue to
drive the vehicle in this state and the Li-
ion battery is close to being completely
discharged, “---” will be displayed. Charge
the Li-ion battery as soon as possible.
When the Li-ion battery is charged, the
original display will be restored.
• After the vehicle is charged, the displayed
driving range is calculated based on the
actual average energy consumption of the
previous driving. The displayed driving
range will vary every time the vehicle is
fully charged.
• The driving range increases or decreases
when the air conditioner, heater or Li-ion
battery warmer (if so equipped) is turned
on or off, or when the ECO mode is se-
lected, or when any other accessory is
turned on or off based on driving.

LI-ION BATTERY AVAILABLE
CHARGE GAUGE
The gauge1indicates theapproximate avail-
able Li-ion battery charge to run the vehicle.
Charge the Li-ion battery before the display
reaches the bottom line.
The low battery charge warning light
illu-
minates when the Li-ion battery available charge
gauge is getting low. Charge as soon as it is
convenient, preferably before the display reaches
the bottom line. When the display reaches the
bottom line and the low battery charge light illu- minates, there is a very small reserve of Li-ion
battery charge remaining.
NOTE:
•
The number of segments illuminated on
the Li-ion battery available charge gauge
is determined by the available charge and
the amount of charge the Li-ion battery is
capable of storing at the current tempera-
ture.
• Temperature affects the amount of charge
the Li-ion battery is capable of storing.
The Li-ion battery is capable of storing
less power when the Li-ion battery tem-
perature is cold. The Li-ion battery is ca-
pable of storing more power when the
Li-ion battery temperature is warm. The
number of segments illuminated on the
Li-ion battery available charge gauge can
change based on the amount of power the
Li-ion battery is capable of storing. For
example, when the Li-ion battery be-
comes colder, more segments on the Li-
ion battery available charge gauge illumi-
nate because the available charge is a
greater percentage of the Li-ion battery’s
capability of storing power. When the Li-
ion battery becomes warmer, less seg- ments on the Li-ion battery available
charge gauge illuminate because the re-
maining energy is a lower percentage of
the Li-ion battery’s capability of storing
power.

Instant ECO driving level
The instant ECO driving level
1is displayed by
the number of bars that increase (more economi-
cal driving) or decrease (less economical driving)
depending on vehicle operation.
Long term ECO driving level
Long term ECO driving is indicated by ECO
TREE symbols. The longer the vehicle is operated
economically, the more segments of the large
ECO TREE symbol
2are displayed. When all of
the segments of the large ECO TREE symbol are
displayed, a small ECO TREE indicator
3is also
displayed, and the large ECO TREE symbol dis-
play is reset. The longer the vehicle is operated
