This LS600h L gasoline-electric hybrid Emergency Response Guide
has been revised to include the changes of the 2010 model year LS600h
L. These changes include minor updates to the vehicle exterior and
interior. The important changes affecting the emergency responder are
the reshaped high voltage battery pack and the addition of pyrotechnic
front seat active headrests. The LS 600h L hybrid introduced in May
2007 continues to share the basic vehicle systems and features of the
conventional, non-hybrid, Lexus LS 460 L.
High voltage electricity powers the electric motor, generator, A/C
compressor, and power control unit (inverter/converter). Other
automotive electrical devices such as the horn, radio, and gauges are
powered from a separate 12 Volt
auxiliary
battery. Numerous
safeguards have been designed into the LS 600h L to help ensure the
high voltage, approximately 288 Volt, Nickel Metal Hydride (NiMH)
Hybrid Vehicle (HV) battery pack is kept safe and secure in an accident.
The LS 600h L utilizes the following electrical systems:
•
Maximum 650 Volts AC
•
Nominal 288 Volts DC
•
Maximum 46 Volts AC / DC
•
Nominal 12 Volts DC
