Charging methods
◆Charging from an external power source (P. 155)
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 charging schedule at the desired date and time.
(P. 166)
◆Using the hybrid battery (traction battery) charge mode
(P. 8 9 )
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. 178)
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).

■“Traction Battery Cooler” (if equipped)
When the hybrid battery (traction battery) is hot, this function pro-
tects it by using the vehicle air conditioning to cool it before
charging is carried out.
When the hybrid battery (trac-
tion battery) is above a certain
temperature and the power
switch is turned off, a check
screen is displayed on the
multi-information display that
indicates whether “Traction Bat-
tery Cooler” is implemented.
When “No” is selected, the hybrid battery (traction battery) cooling sys-
tem does not operate.
■“Traction Battery Heater”
●“Traction Battery Heater” may operate when charging is not being per-
formed.
●When “Traction Battery Heater” is operating, the charging indicator illumi-
nates.
●When “Traction Battery Heater” is operating during charging, the charging
time may be longer than normal.
●If the outside temperature becomes high while “Traction Battery Heater” is
operating, charging may complete earlier than the “Departure” time set.
(P. 166)
