Wait till electric cars are the norm, and this starts happening in attached garages, all over the country! Charging a battery, especially a Li ION battery is still a process that demands the proper respect. When it goes south, it usually does so in spectacular fashion, as illustrated here. And when the process goes critical, pulling the plug does NOT solve your problem. I worked on golf carts, (mainly 36V and 48V electric) for 27 years.
