It is practical to have PHEV's that can be charged at work, especially for those w/out home charging facility and for those with smaller battery packs (8-10 kWh). Quite simple to have rows of solar-PV-covered carports at work with charging receptacles dangling from above. Charge solely from DC solar power on sunny days. No charging on rainy days unless excess of wind power, in order to reduce investment cost on backup fossil fuel power plant. On rainy and calm days, simply use gasoline for ICE-PHEV or hydrogen for FC-PHEV. The cost of solar carport PV per kW installed is comparable with utility solar PV, much lower than residential PV panels. It is very nice to be able to park under a carport at work to protect the car from UV and heat and rain damage. This feature alone is worth the monthly subscription fee...while the ability for low-cost solar charging will be a definit...
