12-volt battery
Provides electricity to various vehicle systems such as the SRS airbags , headlights , wipers , etc .
■ When braking ( regenerative braking )
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 battery .
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 outlets can be used for charging . Procedures are different from refueling a conventional vehicle . Therefore , make sure to read the following thoroughly .
• Charging equipment ( �P . 83 )
• AC charging cable ( �P . 85 )
• Power sources that can be used ( �P . 100 )
• Things to know before charging ( �P . 100 )
• How to charge your vehicle ( �P . 103 , 111 )
• When charging cannot be performed normally ( �P . 131 )
■ Regenerative braking In the following situations , kinetic energy is converted to electric
energy and deceleration 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 driving with the shift position in D .
■ Charging the 12-volt battery
The 12-volt battery is charged from the traction battery when the EV system is operated 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 . 544 )
■ 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 traction battery once a
month . This protects the traction battery from extreme voltage decline due
to self discharging .
●When the vehicle will not be used for an extended period of time , the 12-volt battery will be charged from the traction battery to reduce
the risk of the 12-volt battery discharged . In this case , the cooling fan may operate , however it is not not a malfunction .
●To prevent the 12-volt battery from being discharged , do not leave the charging port lid open or the charging cable connected to the
vehicle .
