Electric Cars Worksheets:
What Are They? –
Electric cars are cars that use electricity for
power. While conventional cars use
gasoline or diesel for fuel, electric cars have
an electric motor which is powered by batteries or a fuel cell.
Types of Electric Cars –
There are three kinds of electric cars: plug-in hybrids, battery-electric cars,
and fuel cell vehicles.
Plug-In Hybrids –
Plug-in hybrid electric vehicles (PHEVs) use both a gasoline or diesel powered engine and an electric motor with a rechargeable battery for
power. They differ from conventional hybrids because they are able to
travel using only battery power.
Battery Electric Vehicles –
Battery-electric vehicles (BEVs) are powered by electricity that is stored in
a battery pack. This electricity is used to power the motor and turn the
wheels. BEVs are recharged by plugging the motor into an electrical wall
outlet or a charging unit.
Hydrogen Fuel Cells –
Fuel cell vehicles use an electric motor that is
powered by hydrogen gas. Though they are powered by electricity and
are considered electric vehicles, they have driving ranges that are
comparable to gasoline and diesel-powered vehicles. Fuel cell vehicles
differ from other electric cars primarily in that they don't need to be
plugged in for long periods of time to recharge.
Hybrid Cars –
A hybrid car is one is powered by a
combination of internal combustion
engine and an electric motor and
battery. The most efficient hybrids get much better gas mileage than
conventional vehicles, have less tailpipe emissions, and cost less to
operate over the life of the vehicle.
History of the Electric Car –
You probably think of the electric car as a modern invention, but it’s not!
Electric cars have actually been around longer than the conventional
internal combustion engine that is used in most vehicles today.
Albert Pope and the Electric Car –
Though they seem to be at the cutting edge of
technology today, electric cars are far from a new
invention. They have actually been around more than
a hundred years.
Tesla's Dream for the Future –
Tesla was founded in 2003 on the belief that driving an electric vehicle in
order to reduce emissions and greenhouse gases should not have to
mean sacrificing a car's performance. Tesla’s dual goal is to move the
world towards a zero-emissions future, while still empowering the modern
What is Electromagnetism? –
Electronic current flowing through a wire generates a magnetic field
which can be increased by coiling the wire so that more current is flowing
through a smaller distance. The magnetic field rotates around the wire,
and the direction of the current determines the direction of the magnetic
