Wait until there home insurance is renewed, most companies dont change rates until renewal time. Also they must be charging them inside the garage or structure. Just renewed my home ins and one of the first questions ask was if I owned an EV and an inhome charging station? The auto ins as well will increase, know of two families that bought EV's and were quit surprised how much their auto ins increased!! A numbervofvstates are currently creating extra taxes to levy on EV's to make up for lost road taxes from not buying gasoline....
