There's a learning curve, all right. One of the prime Rules of driving an EV is "Always have a backup charging option." There is a way that you could have L-2 charging at home, but it might be too labor intensive and pricey: There is a device that will manually or automatically switch loads between a dryer and an EV charging station. You would also apparently need an electrician to make you a 240 volt extension cable to the basement and that dryer outlet. There may also be code issues. You might also price having just one 120 volt 20 amp circuit, with one outlet, installed to plug in an L-1 charging cable. If you have the Nissan original cable, then a 15 amp circuit would be better. If you had to acquire the cable anyway, there are charging cables available that will charge at 16 amps on 120 volts, rather than the 12 amps the Nissan cable uses. Just keep in mind that 120 volt charging is quite slow.
