For anyone to attempt to help you, you will need to provide a LOT more information. Your post has almost no information for anyone to even start trying to help you.
"I just installed my charger" .... so I am going to assume you are not an electrician or you wouldnt be posting for help about a circuit breaker popping.
Installed the wall connector with what exactly? Exactly what type of wire? Exactly what gauge? Exactly what amp breaker? What is your electrical setup (Panel, main service etc)? Are you sure nothing else is on the same circuit? Are you sure you connected everything per the manual for the device? What makes you sure that you did this correctly, if you say you did?
Its obviously not connected correctly, because its popping the breaker. You need to answer those questions above, and also provide pictures of your setup, your charger, distance to the wall connector, etc so that the members here who are competent with this stuff can help you.
I would suggest, though, if you are having issues with this that you should contact an electrician to install it for you. People normalize electricity but this isnt like installing a regular 15 amp wall outlet. Incorrect installation can start a fire and burn your house down, and since people generally charge at night, there is a greater chance of you actually being sleep or something if a fire starts.
Anyway, some more detail and perhaps some of the members here who are technically inclined with electricity will be able to help you. I know a bit about electricity but paid to get mine installed. There are plenty of people here with a lot of knowledge though.
