This Prius Plug-in hybrid Emergency Response Guide has been revised
to include the changes of the 2012 model year Prius Plug-in hybrid.
These changes include minor updates to the vehicle exterior, interior
and hybrid system. The important changes affecting the emergency
responder are the reshaped high voltage battery assembly, HV battery
voltage, and location of charge inlet door. While many features of the
Prius Plug-in hybrid are shared with the 2010 3
hybrid, emergency responders should recognize and understand the
new features of the Prius Plug-in hybrid 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 system. Numerous safeguards have been
designed into the Prius Plug-in hybrid to help ensure the high voltage,
approximately 346 *1/207.2 *2 Volt, Li-ion Hybrid Vehicle (HV)
battery assembly is kept safe and secure in an accident.
