01 · THE IDEA

Electricity, not gasoline.

A fully electric car uses a large battery and an electric motor instead of a gasoline engine.

⚡Electric motor
Engineers had been working on batteries for many years before electric cars became popular.
02 · UNDER THE BODY

Meet the three key parts.

Battery pack

Stores electric energy as direct current (DC).

People must have wondered how a car could move without gasoline.

The faster the motor spins, the faster the wheels turn.
While the driver accelerates, the battery supplies energy to the motor.
05 · SMART ENERGY

Braking can recharge the battery.

🛞 Motor / wheels

When the car slows down, the motor can work as a generator and send some energy back to the battery.

⚡ Battery energy powers the motor.
Early drivers might have believed that braking always wasted energy.

Regenerative braking recovers only some energy; friction brakes are still used.

06 · PLUG IN

Charge it. Drive again.

At a charging station, electricity goes into the car's battery. Once the battery is charged, it is ready to power the motor again.

Governments should have invested in more public charging stations earlier.

07 · CONCLUSION

The future is electric.

An electric car stores energy, converts it, drives the wheels, and can recover some energy while braking.
