HYBRID/ELECTRIC VEHICLES, AND SUPPLEMENTAL RESTRAINT SYSTEMS Flashcards
Under no circumstances should an emergency responder ___. Doing so may result in
severe electrical burns, shock or electrocution
disassemble or remove the cover of the high voltage battery pack
The hybrid gasoline-electric/electric vehicle poses___ over a
conventional vehicle if handled properly at an emergency incident
no additional risk
If the parallel high voltage cable running under the vehicle is damaged, the high voltage battery ___ the entire high voltage battery circuit
will short circuit and deenergize
Currently, three main styles of hybrid vehicles exist: ___
series, parallel and split
Natural gas powered vehicles use either Compressed Natural Gas (CNG) or
Liquefied Natural Gas (LNG), however, __ is more common
CNG
These vehicles are driven by the electric motor alone and as the energy demands of the electric motor deplete the battery, the gasoline-powered generator fires to recharge the battery
Series Hybrid
A ___ hybrid uses both a gasoline engine and electric motor
to move the car forward
parallel
It can run-on electric or gas engine power depending on conditions.
Because of the combination of technology, the ___ hybrid has been cost
prohibitive and is not commonly used.
split
The CNG is stored in high-pressure tanks at___ psi. A full tank
with a serious leak will empty in a few minutes
3000
LNG powered vehicles contain stored natural gas at approximately___ F with a vapor pressure of approximately 15 psi and an expansion ratio of approximately 620:1 (liquid to vapor)
-260 °
The ___ batteries in a hybrid car are the energy storage devices for the electric motor
NiMH (Nickel Metal Hydride)
NiMH High Voltage battery System can range from ___ volts up to ____volts
144-600
All high voltage wires and harness are covered in___ insulation
bright orange
The ___ boosts and inverts the high voltage battery pack to a three
phase AC electricity that drives the motor
inverter
A smart key contains a transceiver which communicates with the
vehicle. When in range, typically less than __’, some vehicle systems may
activate.
16
If the key cannot be located, shutting down the ___ will disable the system
12-V battery
After disabling the vehicle, power is maintained for ____ in the
SRS system and ___ in the high voltage electrical system
90 second 5 minutes
___ REMOVE THE METAL COVER OF THE HIGH-VOLTAGE BATTERY PACK.
DO NOT
To prevent hydrogen gas explosions, it is recommended to
ventilate the vehicle by propping open the ___.
doors and trunk
Should a fire include a vehicle while connected to a charging station, be
sure to _____ prior to extinguishing the fire.
shut down the electricity at the charging station
If LNG is flowing, control by ___
diking
