lectric cars are powered by large
batteries. Batteries store energy.
E There are many types of batteries.
But most batteries have a few things in
common. Each type uses a set of chemicals and
metals to store energy in the form of electricity.
Batteries have two parts called electrodes. One
has a positive charge. The other has a negative
charge. Chemical reactions cause electrons to
move between the electrodes. An electron is a
negatively charged particle. This movement is
called electricity.
Some batteries are used only once.
The electrons flow in one direction. The
chemical reaction stops when both sides
Volkswagen displayed the battery of its e-Up! electric
