Toyota PRIUS 2012 Manual page 2

Foreword
In January 2012, Toyota released the 2012 PRIUS c gasoline-electric
hybrid vehicle in North America. To educate and assist emergency
responders in the safe handling of the PRIUS c hybrid technology,
Toyota published this PRIUS c Emergency Response 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 c to help ensure the high voltage,
approximately 144 Volt, Nickel Metal Hydride (NiMH) Hybrid Vehicle
(HV) battery pack is kept safe and secure in an accident.
The PRIUS c utilizes the following electrical systems:
•
Maximum 520 Volts AC
•
Nominal 144 Volts DC
•
Maximum 27 Volts AC
•
Nominal 12 Volts DC
PRIUS c Features:
•
A boost converter in the inverter/converter that boosts the available
voltage to the electric motor to 520 Volts.
•
A high voltage Hybrid Vehicle (HV) battery pack rated at 144 Volts.
•
A high voltage motor driven Air Conditioning (A/C) compressor
rated at 144 Volts.

•
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 c 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 c identification.
•
Major Hybrid Synergy Drive component locations and descriptions.
