5. In a parallel hybrid electric vehicle drivetrain configuration, how is power delivered to
the wheels?
a. Only the electric motor provides power to the wheels
b. Only the internal combustion engine provides power to the wheels
c. Both the electric motor and internal combustion engine can provide power simultaneously or
independently
d. Power is delivered through a complex hydraulic system
Correct Answer: c. Both the electric motor and internal combustion engine can provide power
simultaneously or independently
6. What is the primary purpose of the equipment grounding conductor in an EVSE
installation?
a. To provide a path for fault current to clear overcurrent devices
b. To reduce electromagnetic interference from the charging cable
c. To improve the efficiency of the charging process
d. To provide a neutral connection for the control circuitry
Correct Answer: a. To provide a path for fault current to clear overcurrent devices
7. When performing load calculations for multiple EVSE units in a commercial installation,
why must the continuous load factor of 125% be applied?
a. To account for future expansion of the charging system
b. Because EVSE is considered a continuous load and the circuit must be sized for the
, 4
continuous current multiplied by 125%
c. To compensate for voltage drop over long conductor runs
d. To meet energy efficiency requirements for LEED certification
Correct Answer: b. Because EVSE is considered a continuous load and the circuit must be
sized for the continuous current multiplied by 125%
8. Which component of the electric vehicle charging system is responsible for converting
alternating current from the grid to direct current for battery charging during Level 2
charging?
a. The EVSE unit itself
b. The vehicle's onboard charger
c. The utility meter at the service entrance
d. The battery management system
Correct Answer: b. The vehicle's onboard charger
9. What distinguishes DC fast charging from Level 1 and Level 2 AC charging methods?
a. DC fast charging uses higher voltage but lower current
b. DC fast charging bypasses the vehicle's onboard charger and delivers DC power directly to the
battery
c. DC fast charging requires a different type of connector for each vehicle manufacturer
d. DC fast charging is only available for commercial vehicles
