1-2. Important points for the EV system
When braking (regenerative brak-
■
ing)
The electric motor (traction motor)
charges the traction battery.
The driving range can be extended by
actively using this regenerative braking
to store electricity in the traction bat-
tery.
Charging
The battery electric vehicle is driven
using electricity, which is received from
an external power source and stored in
the traction battery. Not only public
charging stations, but also household
sockets can be used for charging. Pro-
cedures are different from refueling a
conventional vehicle. Therefore, make
sure to read the following thoroughly.
Charging equipment (P.32)
AC charging cable (P.35)
Power sources that can be used
(P.41)
Things to know before charging
(P.46)
How to charge your vehicle
(P.49, 56)
When charging cannot be per-
formed normally (P.534, 537)
Regenerative braking
■
In the following situations, kinetic energy is
converted to electric energy and decelera-
tion force can be obtained in conjunction
with the recharging of the traction battery.
●
The accelerator pedal is released while
driving with the shift position in D.
The brake pedal is depressed while driv-
●
ing with the shift position in D.
■
Charging the 12-volt battery
The 12-volt battery is charged from the trac-
tion battery when the EV system is oper-
ated or while the traction battery is being
charged.
If the vehicle has not been used for a long
time, the 12-volt battery may become low
due to self-discharge. If this occurs, follow
the correct procedures. (P.526)
When not using the vehicle for an
■
extended period of time
When the vehicle will not be used for an
●
extended period of time, charge the trac-
tion battery once a month.
This protects the traction battery from
extreme voltage decline due to self dis-
charging.
●
When the vehicle will not be used for an
extended period of time, the 12-volt bat-
tery will be charged from the traction bat-
tery to reduce the risk of the 12-volt
battery discharged. In this case, the cool-
ing fan may operate, however it is not a
malfunction.
To prevent the 12-volt battery from being
●
discharged, do not leave the charging
port lid open or the charging cable con-
nected to the vehicle.
■
Charging the traction battery
Be sure to maintain the traction battery
charge level suitable for your driving needs.
If the traction battery fully discharges, the
vehicle cannot be driven at all. When the
battery becomes low, charge it as soon as
possible.
If the traction battery becomes low
■
If the traction battery becomes low, the
●
traction battery charge warning light
comes on or flashes and a message will
be displayed on the multi-information dis-
play. (P.473)
●
If the traction battery is completely dis-
charged, the EV system cannot be
started and driving will not be possible.
When the traction battery becomes low,
charge it as soon as possible.
