Electric cars use big batteries.
They do not use gas. You plug them in to get power. This helps keep our air clean. It is a smart way to go.
Do you like electric cars?
Some cars use only big batteries.
These cars do not have fuel tanks. They use motors to move. You can plug them into a wall to get power.
This can be done at a charging station. Some people even swap old batteries for new ones.
Many things use this power. You can find electric buses and trucks. Some trains use batteries too.
Even boats and bikes can be electric. It is a busy way to travel.
A battery electric vehicle uses only electricity to move.
It gets power from a battery pack on board. This power runs one or more electric motors. These motors make the vehicle move.

Most cars use lithium-ion batteries. These are a type of battery that holds a lot of power. They are better than old lead-acid batteries. They help cars go much further. Lithium-ion batteries help cars speed up quickly. In 2016, people used 210 million electric bikes every day. The Tesla Model Y is the top-selling electric car ever. It has sold about 3.4 million units.
A battery electric vehicle, or BEV, uses only electricity to move.
These vehicles rely solely on an on-board battery pack. This pack sends energy to one or more electric motors. These motors provide the power needed for propulsion. Unlike many other vehicles, BEVs have no fuel tanks. They get their energy by plugging into a charging station or the electrical grid. Some places even use battery swap stations to provide new power.
How these vehicles work is quite different from gas cars. They do not need clutches or complex transmissions. They also do not need the same engine cooling systems. Instead, they use motor controllers to manage power and torque. This helps the vehicle move smoothly. New lithium-ion batteries are very helpful for this process. They have a high energy density, which means they hold more power. This allows for better acceleration and more range.
People have been working on electric vehicles for a long time. In the 1880s, Gustave Trouvé, Thomas Parker, and Andreas Flocken built experimental models. The first practical battery electric vehicles appeared during the 1890s. In 1931, battery-powered milk floats began to expand. By 1967, Britain had the largest electric vehicle fleet in the world. Today, many different types of vehicles use this technology. This includes cars, buses, trucks, motorcycles, and even bicycles.
There are many impressive numbers in the world of electric transport. In 2016, there were 210 million electric bikes used every day. The Tesla Model Y is the top-selling electric car in history. It has reached an estimated 3.4 million sales. The Tesla Model 3 follows with over 2.6 million sales. The Wuling Hongguang Mini EV has sold 1.4 million units. In Japan, battery electric railcars are even used for trains.
You might see these vehicles in many parts of your life. Some cities use electric buses to reduce pollution. In Chattanooga, Tennessee, nine electric buses have carried 11.3 million passengers. In Adelaide, Australia, the Tindo bus gets power from solar panels. Even large ships can be electric, like the China Zorrilla ferry.
These vehicles help people travel while using different kinds of energy. They show how technology can change how we move through the world.
A battery electric vehicle, often called a BEV, is a type of vehicle that relies exclusively on electrical energy.
This energy is stored in an on-board battery pack. The battery powers one or more electric traction motors. These motors provide the propulsion needed to move the vehicle. Because they use only electricity, BEVs have no fuel tanks. This makes them different from hybrid electric vehicles (HEVs). Hybrids use both electric motors and internal combustion engines. They also differ from fuel cell electric vehicles (FCEVs), which use fuel to create electricity.
To make the vehicle move, the system uses motor controllers. These controllers modulate the output of engine power and torque. This process allows the vehicle to function without certain parts found in gas cars. For example, BEVs do not need clutches or complex transmissions. They also do not require the sophisticated engine cooling systems used in internal combustion engines. To replenish their energy, drivers plug the vehicle into a charging station or the electrical grid. Some locations even use battery swap stations. These stations allow a driver to get a new, charged battery instead of waiting to plug in.
There are many different types of battery electric vehicles in use today. While many people think of passenger cars, the technology applies to many machines. This includes buses, trucks, motorcycles, scooters, and even bicycles.
Some electric vehicles are even used on rails. In Japan, battery electric multiple units (BEMUs) operate commercially. These railcars charge via pantographs while driving on electrified lines or at special stations. They can also use battery power on lines that are not electrified. In cities, battery electric trams can operate without overhead wires. This is helpful in historic city centers where wires might not look good.
Humans have been experimenting with this technology for over a century. During the 1880s, Gustave Trouvé, Thomas Parker, and Andreas Flocken built experimental electric cars. Practical battery electric vehicles began to appear in the 1890s. In 1931, battery-powered milk floats began to expand. By 1967, Britain held the largest electric vehicle fleet in the world. In the modern era, sales have grown rapidly. In September 2016, global sales of highway-capable light-duty pure electric cars passed one million units. The Tesla Model Y is currently the top-selling electric car in history, with an estimated 3.4 million sales.
Science has improved the efficiency of these vehicles through better battery technology. Modern lithium-ion batteries have a much higher energy density than older lead-acid batteries. Energy density measures how much energy a substance holds in a certain space. Lead-acid batteries have an energy density of 0.36 MJ/L. In contrast, lithium-ion batteries have an energy density between 0.9 and 2.63 MJ/L. This makes them 2.5 to 7.3 times more efficient. However, petroleum-based fuels still have much higher energy densities. Gasoline ranges from 34.2 MJ/L, while ethanol is around 24 MJ/L. Even so, electric motors are very efficient. BEVs can travel roughly three times further per MJ of stored energy than similar internal combustion vehicles.
We see these vehicles performing important jobs in many cities. In Chattanooga, Tennessee, nine electric buses have carried 11.3 million passengers since 1992. In Australia, the Tindo bus uses electricity from a solar PV system at a central station.
Large scale transport also uses this technology. The China Zorrilla ferry is the largest battery electric vehicle ever built. It measures a great length and uses a 40 MWh battery system.
Even small delivery tools like the StreetScooter van are used by companies like DHL to deliver mail.
Battery electric vehicles are closely connected to global efforts to reduce pollution. Because they have zero emissions during use, they can significantly reduce pollution in cities. This technology is also helping to reduce dependence on oil. Many governments are now pledging billions of dollars to fund the development of electric vehicles. This support helps improve battery technology and charging infrastructure. As more people use electric bikes and cars, the way we move through the world continues to change.
