energy. Distance to empty displayed
on the vehicle may be higher or lower
than the certification range because
these effects are considered.
僅 Driving style refers to driving speed
and acceleration/deceleration ten -
dency. The higher the speed, or the
more frequent the acceleration/decel -
eration, distance to empty will be
reduced.
僅 Electrical loads usage means air con -
ditioning, heaters, lamps or additional
auxillary loads, and as the usage
increases, distance to empty will be
reduced.
僅 Environment refers to weather, tem -
perature, and terrain. Distance to
empty is reduced in cases of snow/
rain/high winds or low temperatures,
uphill or slippery or rough road sur -
faces.
僅 High voltage battery energy is propor -
tional to SOC (charge amount), but
may vary depending on the battery
temperature, SOH (battery health),
etc.
Change of distance to empty
when 100% charging
僅 If the distance to empty is lowered
due to learning by the driving style or
the environment in which the vehicle
is used, the driving distance may be
increased again if the vehicle contin -
ues to drive according to the "driving
tips for improving the driving dis -
tance". The distance to empty can be
reset at the workshop, but it does not
actually increase the range. There -
fore, the distance to empty may be
inaccurate until the learning proceeds.
僅 Distance to empty decreases when
the high voltage battery temperature
1 36
is low in winter. It is not a permanent
change. If the temperature rises, the
distance to empty is restored.
僅 Reducing the use of electrical loads
increases the range available.
僅 Natural degradation of the high volt -
age battery occurs depending on the
length of use of the vehicle, which
reduces the distance to empty.
Operating tips to improve driving
range.
僅 As electric vehicles speed up, air resis -
tance increases rapidly, so not speed -
ing helps more driving range.
僅 High driving energy is consumed
during rapid acceleration. Motor
regenerative braking is restricted
during rapid deceleration. Keep the
accelerator pedal position constant
and drive at a constant speed.
僅 Excessive operation of the heater and
air conditioner can increase power
consumption and shorten the driving
range. When setting the temperature
to 22C (72 F) auto, optimal energy
consumption driving is possible. In
particular, using a heated seat and
reducing air heating in winter is very
helpful. Turn off the heater and air
conditioner when heating and cooling
are not needed.
僅 Selecting recirculation mode con -
sumes less energy than selecting
fresh mode. In the fresh mode, energy
consumption is large because the out -
door air must be reheated or cooled.
When driving with the window open,
air resistance increases and heater
and air conditioner usage increases.
So close the window completely while
driving to reduce energy consump -
tion.
