Batteries could fuel solar, wind growth - On an arid mountain in Eureka County, Nev., a mining company believes it's struck the 21st-century equivalent of gold.
As the range of an EV increases, primarily a result of battery energy density increasing--more KWh in the same size package--it takes more energy to charge them. This means one must either increase the charge time at a given charge power level or increase the charge power level for the same charge time. This means special charging systems for home owners since common household receptacles are limited in amperage to relatively low values. If a new, faster charging receptacle is added, one then has to consider the breaker box and the size of the service to the household and dissipating the heat from the charging process.
