2-2. Charging
Electric Vehicle system
Before charging, always check the
following items.
 The parking brake is applied.
( P.254)
 The power switch is turned to
OFF. ( P.243)
 Lights such as the headlights,
emergency flashers and interior
lights, etc., are turned off.
If these light switches are turned on,
then these features will consume elec-
tricity, and charging time will increase.
Before charging, make sure that
each part of the AC charging cable
is in good condition. ( P.106)
■During charging
●The charging starting time may differ
depending on the state of the vehicle, but this does not indicate a malfunc-
tion.
●During charging, sounds may be
heard from near the traction battery in accordance with the operation of the air conditioning system or “Battery
Cooler” ( P.115).
●During and after charging, the motor
compartment and its surrounding area in which the onboard traction battery charger is installed may get warm.
●The surface of the CCID (Charging Circuit Interrupting Device) may
become hot, but this does not indicate a malfunction.
●Depending on radio wave conditions,
interference may be heard on the
radio.
■When charging using a public charging facility
●When charging using a public charging facility, check the setting of the charging schedule function.
• When the charging schedule is regis- tered, temporarily turn off the function or turn “Charge Now” on. ( P.134)
• When the charging schedule is set to on, charging will not start even if the AC charging cable is connected. Also,
charging fee may occur due to con- nection of the AC charging cable.
■Capacity reduction of the traction battery
The capacity of the traction battery will decline gradually when the traction bat-tery is in use. The rate at which it
declines will differ in accordance with environmental conditions and the way in which the vehicle is used. Observing the
following can help suppress the decline in the traction battery capacity.
●Avoid parking the vehicle in high tem-perature areas, under direct sunlight when the traction battery is fully
charged.
●Avoid accelerating and decelerating
frequently and suddenly.
●Avoid frequent driving at high speed.
●Use the charging schedule function as much as possible in order to fully
charged the traction battery before starting off. ( P.134)
●Avoid frequent DC charging
Also, if the capacity of the traction bat-
tery capacity reduces, the distance that
can be driven decreases. However,
vehicle performance does not signifi-
cantly become worse.

charging completes may be less than
normal in order to protect the traction battery (the driving range after the bat-
tery is fully charged may be shorter).*
●Charging is performed when the out- side temperature is low or high
●Charging is performed immediately after high-load driving or in extreme
heat
In any other situation, if the remaining
charge of the traction battery is signifi-
cantly lower than normal after charging
completes, have the vehicle inspected
by any authorized Toyota retailer or
Toyota authorized repairer, or any reli-
able repairer.
*: When this occurs, even if the remain-
ing charge display of the traction bat-
tery shows that it is fully charged, the
remaining charge rapidly decreases
faster than normal.
■When the charging amount sent to the traction battery decreases
When the amount of power supplied by
the charger is low or operation of the battery heater, etc., reduces the charging power sent to the traction bat-
tery, the charging amount sent to the traction battery may decrease.
■Charging time may increase
In the following situations, charging time
may become longer than normal:
●In very hot or very cold temperatures.
●When the traction battery becomes hot, such as immediately after high-
load driving.
●The vehicle is consuming a lot of elec-
tricity, for example, when the head- lights are on, etc.
●When using “My Room Mode”. ( P.145)
●There is a power outage during charging.
●There is an interruption in the electri-cal supply.
●There is a drop in the voltage of exter-
nal power source.
●The charge in the 12-volt battery is
low, for example due to the vehicle being left unused for a long period of time.
●When the upper limit of charging cur-rent is changed in the charging cur-
rent setting of the vehicle ( P.124)
●When the battery heater operates.
( P. 1 1 5 )
●When the “Battery Cooler” is operated
before charging. ( P. 1 1 5 )
●When the plug generates heat due to
a loose socket connection, etc.
●When adjusting the power supply with
the charger.
●When frequently and repeatedly using
DC charging.
●When selecting “DC charging power”
setting other than “MAX”.
●When the temperature of charging-
related parts is high.
