Foreword
In June 2011, Toyota released the 2012 Prius V gasoline-electric hybrid
vehicle in North America. To educate and assist emergency responders
in the safe handling of the Prius V hybrid technology, Toyota published
this Prius V Emergency Response Guide.
The Prius V is based on the 3
rd
generation Toyota Prius. While many
features from the Toyota Prius and Prius V are similar, emergency
responders should recognize and understand the new, updated features
of the Prius V covered in this guide.
High voltage electricity powers the electric motor, generator, air
conditioning compressor and inverter/converter. All other automotive
electrical devices such as the headlights, radio, and gauges are powered
from a separate 12 Volt auxiliary battery. Numerous safeguards have
been designed into the Prius V to help ensure the high voltage,
approximately 201.6 Volt, Nickel Metal Hydride (NiMH) Hybrid
Vehicle (HV) battery pack is kept safe and secure in an accident.
The Prius V utilizes the following electrical systems:
•
Maximum 650 Volts AC
•
Nominal 201.6 Volts DC
•
Maximum 27 Volts AC
•
Nominal 12 Volts DC
Prius V Features:
•
A boost converter in the inverter/converter that boosts the available
voltage to the electric motor to 650 Volts.
•
A high voltage Hybrid Vehicle (HV) battery pack rated at 201.6
Volts.
•
A high voltage motor driven Air Conditioning (A/C) compressor
rated at 201.6 Volts.
•
A body electrical system rated at 12 Volts, negative chassis ground.
•
Supplemental Restraint System (SRS) - dual stage frontal airbags, a
driver knee airbag, front seat side airbags, side curtain airbags and
front seat belt pretensioners.
•
An Electric Power Steering (EPS) assist motor rated at 27 Volts.
High voltage electrical safety remains an important factor in the
emergency handling of the Prius V Hybrid Synergy Drive. It is
important to recognize and understand the disabling procedures and
warnings throughout the guide.
Additional topics in the guide include:
•
Prius V identification.
•
Major Hybrid Synergy Drive component locations and descriptions.
•
Extrication, fire, recovery, and additional emergency response
information.
•
Roadside assistance information.
