■The charging environment
For safe charging, the following charging equipment and settings are recom-
mended.
●Rain-tight socket
When charging outdoors, connect the plug to a rain-tight socket, and ensure
that the plug remains waterproof while the plug is connected.
●Dedicated circuit
• To reduce the risk of fire, connect only to an at least 13A branch circuit
with an over-current protection.
• To reduce the risk of electric shock when working with the plug, connect
to a socket that has a Residual Current Circuit-Breaker (RCCB) installed.
●Remote switch
Allows the electricity from the socket to be interrupted by operating a switch,
thus allowing safe removal and insertion of the plug on rainy days.

WARNING
■Power sources precautions
Observe the following precautions.
If you do not follow them, fire, electrical shock and/or damages may occur,
possibly resulting in death or serious injury.
● Connect to an AC 220 V - 240 V socket with a Residual Current Circuit-
Breaker (RCCB) and supplied by a circuit breaker in line with local regula-
tions. Use of an individual circuit provi ded with at least 13A is strongly rec-
ommended.
● Use of a block heater socket which fails to meet the requirements is pro-
hibited for charging.
● Make sure to connect the charging connector and charging inlet directly.
Do not connect a converting adaptor or extension cord between the
charging connector and charging inlet.
● Do not connect the charging cable to a
multi-socket adapter, multi-plugs, or

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.
