A dryer outlet is typically 30A, so that would limit you to a 24 amp charger. But you definitely don't want to have a dryer and car charger on the same circuit (it might even be a code violation - but consult an electrician). If you're like me and you have a gas dryer (and an unused dryer outlet), having the outlet relocated to your garage might be an option. I had this option, but opted to have a 50A circuit put in the garage since my breaker box could support it and because the cost was not substantially greater.
