EV driving range
The value displayed on the multi-information display etc. (P. 218,
234, 241, 258) is estimated from the following information.
●The amount of hybrid battery (traction battery) charge currently
remaining
●The electricity consumption (the estimated distance that can be
driven in EV mode per unit of electrical energy) based on the
recorded value
●Past air conditioning system electricity consumption amount
The electricity consumption varies depending on how the vehicle is
driven. The vehicle automatically records the electricity consumption
when being charged and uses the electricity consumption for estimat-
ing the EV driving range. Therefore, the EV driving range displayed
when the hybrid battery (traction battery) is fully charged may differ
from the previous EV driving range depending on how the vehicle was
driven.
The EV driving range may change significantly with each charging
until the electricity consumption based on the recorded value is stable
(for approximately the first month or two). However, this does not indi-
cate a malfunction.
When the air conditioning system is turned on, the EV driving range
(with using the air conditioning system) is estimated based on the past
air conditioning electricity consumption amount considering that the
electricity consumption may become higher.
The EV driving range displayed on the multi-information display
etc. shows the reference distance that EV driving (driving using
only the electric motor) is possible, and the actual distance that
can be driven may differ from that displayed.
Even if the EV driving range is displayed, EV driving may be can-
celed and both gasoline engine and electric motor are used depend-
ing on the situation. (P. 106)

The distance that can be driven in EV mode varies significantly
depending on how the vehicle is driven, road conditions, the weather,
the outside temperature, usage conditions of electrical components
and the number of occupants.
The distance that can be driven in EV mode can be extended if the fol-
lowing is performed:
●Maintain a safe distance from the vehicle in front and avoid unnec-
essary acceleration and deceleration
●Accelerate and decelerate the vehicle as smoothly as possible
●Drive at moderate speeds as much as possible and maintain a con-
stant speed
●
Set the air conditioning to a moderate temperature and turn the “A/C”
switch ( ) off when it is not needed
●Use tires of the specified size and maintain the specified tire pres-
sure
●Use the EV/HV mode selection switch to drive in HV mode when
driving on a highway
Electricity consumption will increase substantially when driving on a
highway in EV mode.
●Do not add unnecessary weight to the vehicle
The following indicate that charging has been carried out properly.
●The charging indicator turns off
●The Hybrid battery (traction battery) status indicators illuminate for
approximately 15 seconds. (P. 123)
●“Charging Complete” is displayed on the multi-information display
when starting off (P. 154)
Regardless of the type of power source or whether the charging timer
function is used, charging is completed if the above can be confirmed.

When the charging cable is con-
nected to the charging inlet, the
user is informed of the charging
status of the hybrid battery (trac-
tion battery) by the statuses of 3
indicators (turned off, illuminated
or flashing).

The illumination/flashing pattern
changes to inform the user of the
charging status in the following
ways.
*1: If equipped
*2: Flashes for approximately 15 seconds.
*3: Flashes for approximately 10 seconds.
■Charging indicator
When a system malfunction occurs while charging or using the Remote Air
Conditioning System, the charging indicator rapidly flashes for approximately
10 seconds, and then turns off.
If this occurs, the next time the hybrid system is started, a message is dis-
played on the multi-information display. When a message is displayed, follow
the instructions displayed on the screen.

Charging methods
◆Charging from an external power source (P. 160)
This is a charging method used when charging from an AC socket
(220 V-240 V) with the charging cable equipped to the vehicle or
charging at a public charging station.
The charging start time (or departure time) and day can be set to carry
out charging using the timer at the desired date and time. (P. 171)
◆Using the hybrid battery (traction battery) charge mode
(P. 101)
The plug-in hybrid system can be switched to hybrid battery (trac-
tion battery) charge mode to charge the hybrid battery (traction bat-
tery) using electricity generated by gasoline engine operation.
The maximum charge amount in the hybrid battery (traction battery)
charge mode is approximately 80% of the fully charged capacity for the
charging from an external power source.
◆Solar charging system (if equipped) (P. 183)
In certain conditions, when the vehicle is parked, the hybrid battery
(traction battery) can be charged by using electricity generated by
the solar panel equipped to the roof of the vehicle.
The maximum charge amount of the solar charging system is approxi-
mately 90% of the fully charged capacity for the charging from an exter-
nal power source. (This does not mean the battery can be fully charged
in one day.)
The following methods can be used to charge the hybrid battery
(traction battery).

1482-2. Charging
PRIUS PHV_OM_OM47C99E_(EE)
The time required to charge the hybrid battery (traction battery) differs
according to the charging voltage and charging current.
*1: The charging voltage may differ depending on the target region.
*2: This is the maximum value. Furthermore, the upper limit of the charging
current can be changed in the “Vehicle Settings” settings. (P. 145)
*3: The time required for charging to complete depends on conditions such as
the remaining charge of the hybrid battery (traction battery) and the outside
temperature.
