1. A fleet manager is developing an electrification strategy for a mixed-
duty fleet and wants to determine which vehicles should be
considered first for replacement with battery-electric vehicles (BEVs).
Which approach provides the strongest foundation for making this
decision while minimizing operational disruption?
A. Replace the oldest vehicles first regardless of their duty cycle, route
characteristics, or energy requirements
B. Select vehicles solely according to the lowest advertised purchase price of
available electric models
C. Analyze duty cycles, daily mileage, dwell time, payload, operating
environment, charging availability, total cost of ownership, and mission
requirements before selecting vehicles
,D. Replace all internal-combustion vehicles simultaneously so that the fleet
immediately becomes fully electric
Answer: C.
A sound fleet-electrification strategy begins with operational requirements
rather than simply vehicle age or acquisition price. Duty cycles, mileage,
payload, dwell time, charging access, climate, terrain, and total cost of
ownership determine whether an electric vehicle can reliably perform the
assigned mission.
2. Which characteristic most directly distinguishes a battery-electric
vehicle from a conventional internal-combustion-engine vehicle in
terms of its primary propulsion energy pathway?
A. A BEV converts electricity stored in a traction battery into mechanical
energy through electric motors
B. A BEV burns gasoline inside a combustion chamber and uses an alternator
to create propulsion electricity
C. A BEV uses diesel combustion to mechanically rotate a transmission and
then charges its traction battery
D. A BEV uses compressed natural gas as its primary energy source and
electricity only for accessories
Answer: A.
,A battery-electric vehicle stores electrical energy electrochemically in a
traction battery and converts that energy through power electronics and
electric motors into vehicle motion.
3. A fleet manager is comparing a battery-electric vehicle with a gasoline
vehicle that performs the same daily route. Which financial analysis is
most appropriate for a long-term fleet acquisition decision?
A. Compare only the manufacturer's suggested retail prices
B. Compare only annual fuel expenditure
C. Compare total cost of ownership over the expected service life
D. Compare only the first year's maintenance expense
Answer: C.
Total cost of ownership incorporates acquisition, financing, energy,
maintenance, infrastructure, depreciation, residual value, downtime, and
other relevant costs throughout the vehicle's operating life.
4. Which factor is most likely to reduce the effective driving range of a
battery-electric fleet vehicle?
A. Moderate regenerative braking
B. High accessory loads combined with extreme temperatures and
demanding driving conditions
, C. Charging the vehicle during periods of low electricity demand
D. Using a properly calibrated tire-pressure monitoring system
Answer: B.
Extreme temperatures, heating or cooling loads, high speeds, heavy
payloads, aggressive acceleration, terrain, and other demanding operating
conditions can increase energy consumption and reduce practical driving
range.
5. A fleet operates vehicles that return to a central depot every evening
and remain parked for 10 hours. Which charging strategy would often
be particularly attractive for these vehicles?
A. Depend exclusively on public DC fast charging during business hours
B. Use depot-based charging during the long overnight dwell period
C. Eliminate charging infrastructure and rely on regenerative braking
D. Charge only when the battery reaches zero percent state of charge
Answer: B.
Long predictable dwell periods create an excellent opportunity for depot
charging, particularly when vehicles can receive sufficient energy during
overnight or other scheduled idle periods.
6. What does state of charge (SOC) represent in an electric vehicle?
