An electric van is like a big car that runs on a special type of power called electricity instead of gas. Just like your toys need batteries to work, an electric van needs a big battery to make it go. The battery is what holds all the electricity that the van needs to drive around.
When you plug in the cord that comes with the van into a special outlet, the battery gets charged up with electricity. Then, when you're ready to drive, the battery sends the electricity to the electric motor, which is what makes the van move.
Because it's powered by electricity, an electric van doesn't make any loud noises or smelly fumes when it's moving. This makes it a great choice for people who want to help the environment and reduce air pollution. Plus, it can save people a lot of money because they don't need to buy gas for it, just electricity.
