Our currant Battery Electric Vehicles for private use, like a Mode 3 Tesla or a Ford Lightning, have a range around 250 to 350 miles. These vehicles get about 3 to 4 miles per kilowatt-hr of energy usage. Thus the usual battery size runs from around 60 KWhs to about 100 KWhs.
Now to recharge these batteries, there are several "levels" of charging systems available. At our houses, we have outlets with 120 volts, rated for about 20 amps. As high school physics students know, volts times amps equals watts, so our home circuit could charge at a rate of 2.4 Kws, and so if operated for one hour, would replenish about 2.4 KWhs of available energy.
Such a system will work well to replenish our daily "about town" driving using about 10 KWhs of energy. Our homes also use about 10 KWhs of energy each day (monthy total aound 300 KWhs). Therefore, if we install a solar power system rated for say 5 KW, we could generate enough power most days to power our home and car.
Lets say a solar power system delivers about 6 hours worth of full capacity on average each day, or about 30 KWhs, leaving a surplus many days to off-set utility system usage during winter or cloudy days.
Bottom line, our transition to BEV's should be possible over a 10 to 15 year period, provided solar power installations remain competitive.
