Question 1

The regenerative braking system makes hybrids ideal for delivery vehicles and city transit buses that operate in stop-and-go conditions all day long.

Accepted Answer

Regenerative braking systems are efficient in stop-and-go conditions as they recover energy during braking, making hybrids suitable for delivery vehicles and city buses.

Question 2

When a hybrid vehicle is being stopped, most of the kinetic energy of the vehicle's movement is converted into heat by the friction of the brake pads against the brake rotors; therefore, all of this energy is lost.

Accepted Answer

Hybrid vehicles often use regenerative braking, which captures some of the kinetic energy and converts it into electrical energy to recharge the battery, reducing energy loss.

Question 3

The harder the driver steps on the brake pedal of a hybrid vehicle, the more electricity is generated by the electric motor during the regenerative braking process.

Accepted Answer

The electric motor in a hybrid vehicle acts as a generator during regenerative braking, converting the kinetic energy of the vehicle into electrical energy. The harder the driver steps on the brake pedal, the greater the force applied to the electric motor, resulting in more electricity being generated.

Question 4

During which driving mode does the reduction in size of the Internal Combustion Engine (ICE) in a hybrid vehicle results in fuel savings?

Accepted Answer

In city driving, the ICE is used more frequently for acceleration and deceleration, so a smaller ICE can save fuel. In highway driving, the ICE is used less frequently, so a smaller ICE would not result in significant fuel savings.

Question 5

At approximately what speed does a hybrid vehicle switch from electric-only propulsion to a mode that uses both electric and internal combustion engine propulsion?

Accepted Answer

The answer of At approximately what speed does a hybrid...

Question 6

Many full hybrid vehicles can operate at low speeds using the electric motor only. These cars typically begin using the internal combustion engine at _________.

Accepted Answer

The answer of Many full hybrid vehicles can operate at...

Question 7

An electric motor is capable of creating its maximum torque as soon as it begins spinning.

Accepted Answer

Electric motors can produce maximum torque at zero RPM, which means they can deliver full torque from a standstill.

Question 8

On many full hybrids, which of the following can be used to propel the vehicle during low speed operation?

Accepted Answer

The electric drive motor can propel the vehicle during low-speed operation in many full hybrids, allowing for efficient and quiet driving.

Question 9

When a driver presses on the accelerator pedal in a hybrid vehicle, the PCM commands the ________ to apply electricity to the electric motor until the vehicle reaches speeds up to approximately 40 miles per hour (64 kilometers per hour).

Accepted Answer

The high-voltage battery pack supplies electricity to the electric motor, allowing the vehicle to accelerate until it reaches a certain speed, typically around 40 mph, before the gasoline engine takes over.

Question 10

All of the following statements are true except:

Accepted Answer

High voltage gloves should be regularly inspected and tested for any damage, not just major damage, to ensure safety. They should be discarded if they fail inspection or testing, even if the damage is minor.

Question 11

Tech A states that before performing service on some components on a hybrid vehicle it will be necessary to shut off the high voltage system. Tech B states that high voltage gloves must be worn when working on high voltage circuits. Who is correct?

Accepted Answer

Both Tech A and Tech B are correct. Shutting off the high voltage system is necessary to ensure safety when servicing hybrid vehicles, and wearing high voltage gloves is essential when working on high voltage circuits to prevent electric shock.

Question 12

Tech A states that high voltage gloves should be replaced every year. Tech B states that high voltage gloves should be tested or replaced every 6 months. Who is correct?

Accepted Answer

High voltage gloves should be tested or replaced every 6 months to ensure safety and compliance with safety standards.

Question 13

Tech A states that the Prius drive system only uses electric motors to propel the vehicle in reverse. Tech B states that the Prius drive system uses a small planetary gear set for reverse. Who is correct?

Accepted Answer

The Prius drive system uses electric motors to propel the vehicle in reverse, not a planetary gear set.

Question 14

Tech A states that high voltage wiring will be encased in color coded conduit to identify the high voltage. Tech B states that many connectors on hybrids will have an interlock system built in that will turn off the high voltage system if the connector is unplugged. Who is correct?

Accepted Answer

High voltage wiring in hybrid vehicles is often encased in color-coded conduit for safety and identification, and many connectors have an interlock system to disable the high voltage when disconnected.

Question 15

Technician A says that hybrid vehicles have an internal combustion engine and an electric motor. Technician B says that most hybrid vehicles utilize regenerative braking to help improve fuel economy. Who is correct?

Accepted Answer

Hybrid vehicles typically combine an internal combustion engine with an electric motor, and they often use regenerative braking to recover energy and improve fuel economy.

Question 16

Technician A says that hybrid vehicles have an internal combustion engine and an electric motor. Technician B says that most hybrid vehicles utilize regenerative braking to help improve fuel economy. Who is correct?

Accepted Answer

Hybrid vehicles typically have both an internal combustion engine and an electric motor, and they often use regenerative braking to improve fuel economy by converting kinetic energy back into stored energy.

Question 17

Technician A says that Belted Alternator Starter (BAS) vehicles use an alternator to help slow the vehicle and act as a starter. Technician B says that the BAS alternator can be used to propel the vehicle without the internal combustion engine. Who is correct?
