Project #114 Hybrid Car Concept
Hybrid
Set the slide switch (S5) to position B and
turn the hand crank (HC). The red LED
(D1) lights, the meter measures the
voltage, and the fan spins.
The meter scale is 10V (not 5V), due to a
scaling resistor in the pivot stand.
Set the slide switch (S5) to position C and
turn the hand crank (HC). The red LED
(D1) lights when the crank is charging the
battery (B4).
Set the slide switch to position B to run the
motor (M4) using the battery. If you turn
the crank now, if will both charge the
battery and run the motor.
Project #113
The motor is powered by the hand crank or stored
energy from the 470
μF capacitor (C5). It might be
called a hybrid, because it runs on power from either
source. However, the capacitor does not store much
energy, so it will run the motor for only a very short
time. If the rechargeable battery were used here, the
motor would run for much longer.
5V
This circuit demonstrates the concept of hybrid cars. A
power source (the hand crank is used here) charges a
battery (B4 here) in a car. The car has an electric motor
(not a gasoline powered motor), which is powered by
electricity from the battery. Some electric cars also have
gasoline powered motors as backups, incase you are
driving a long distance and your battery runs out of charge.
