Electric Vehicles (EVs) have to be charged. Unlike a petrol car, you can do this at home, just plug the charging cable into a normal home socket. That has the advantages of simplicity. However there are disadvantages.

The standard 3-pin socket can only supply a small amount (only a trickle) of electricity to your car. This means your EV’s battery charges very slowly. It can take anywhere from seven hours to more than a day to completely charge an electric vehicle, depending on how big the battery is. This is obviously an issue, if you are using your EV every day.

The other drawback to a normal 3-pin socket is that there is no safety mechanism to keep the plug in the securely. If you trip on the cable, or a child messes around with it, the plug can come out. That’s not safe.
