Charging methods
◆Charging from an external power source (P. 143)
This is a charging method used when charging from an AC outlet
(120 V) with the charging cable equipped to the vehicle or char ging
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. 154)
◆Using the hybrid battery (traction battery) charge mode
( P. 87)
The plug-in hybrid system can be switched to hybrid battery (trac-
tion battery) charge mode to charge the hybrid battery (tractio n bat-
tery) using electric ity generated by gas oline 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.
The time required to charge the hybrid battery (traction battery) differs
according to the charging vol tage and charging current.
*1: This is the maximum value. Furthermore, the upper limit of the charging
current can be changed in the “Vehicle Settings” settings. ( P. 1 2 9 )
*2: 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.
The following methods can be used to charge the hybrid battery
(traction battery).

■Capacity reduction of the hybr id battery (traction battery)
The capacity of the hybrid battery (traction battery) will decline gradually
when the hybrid battery (traction battery) is in use. The rate at which it
declines will differ in accordance with environmental condition s and the way
in which the vehicle is used. Observing the following can help suppress bat-
tery capacity decline.
● Avoid parking the vehicle in areas with a high temperature unde r direct sun-
light when the hybrid battery (traction battery) is fully charged.
● Avoid accelerating and decelerating frequently and suddenly when EV driv-
ing.
● Avoid frequent driving near the top speed for EV driving. ( P. 93)
● Leave a low level of charge in the hybrid battery (traction bat tery) when
leaving the vehicle undriven for a long period of time.
After confirming that EV mode has switched to HV mode, turn the power
switch off.
● Use the charging timer function as much as possible in order to fully
charge the hybrid battery (traction battery) immediately before starting
off. ( P. 154)
Also, if the hybrid battery (traction battery) capacity reduces , the distance that
can be driven in EV mode decreases. However, vehicle performanc e does
not significantly become worse.
■ When the remaining charge of the hybrid battery (traction battery) is low
after charging
In the following situations, the remaining charge of the hybrid battery (traction
battery) after charging completes may be less than normal in or der to protect
the system (the EV driving range after the battery is fully charged may be
shorter).
*
● Charging is carried out when the outside temperature is low or high
● Charging is carried out immediately after high-load driving or in extreme
heat
