SAE J1772

SAE J1772 is a special kind of plug for electric cars. Just like how your toys need batteries to work, electric cars need electricity to go. So, you can imagine that it is a very important plug for electric car owners.

The plug has different parts to it. The first part is the handle that sticks out from the charging station. The handle is where you hold and insert the plug. Similar to when you play with Legos, there is a specific way that the plug connects into the handle.

The second part is called the cord. It looks like a long, skinny rope that connects the handle to the electric car’s charging port. You can think of it like a rope that connects your toy to a battery.

SAE J1772 is special because it has different pins on the inside of the plug that allow for specific directions of electricity to correctly flow from the charging station to the electric car’s battery. When the plug is in place, the electricity flows from the charging station, through the cord, into the electric car battery. This is how electric cars get the energy they need to drive.

Overall, SAE J1772 is just a special kind of plug for electric cars that has different parts and specific pins that make sure the electricity flows in the right direction. This way, electric cars can be charged safely and efficiently.
