O preço das baterias está a baixar com o passar do tempo (Batteries will decline in price over time)

"Seems some people really are putting in some hard work to build our charge networks....

A snippet...

"Batteries will decline in price over time. - A couple years ago, lithium-ion batteries sold for around $900 a kilowatt hour, according to various estimates. Now lithium batteries sell for less than $500 a kilowatt hour. In December 2010 study, Deutsche Bank (DB) analysts revisited some figures posted in its previous report and lowered their projected future costs for automotive batteries. DB's December 2010 study pegged the cost of lithium-ion batteries at $250 per kWh by 2020, a substantial reduction from the $350 per kWh it forecasted back in November 2009"

Economics of Charge Stations - A profitable business model for public charging infrastructure has not been reliably demonstrated. The only way for consumers to recover the cost of an expensive battery is to defray it over time with comparatively cheap electricity. This upper bound on the price consumers are willing to pay to charge their vehicles, and the readily available substitute of home charging, places an upper limit on what consumers will be willing to pay for public charging.

PHEVs require new supporting infrastructure, such as charge stations. Economies of scale for these services may or may not exist. The uptake of EVs and PHEVs is unlikely to be uniform across cities, neighborhoods or even streets, but charging points will need to be in place ahead of market uptake as no consumer would buy such a vehicle if they are unable to easily recharge their vehicle. Therefore a degree of under-utilization of charging points would be expected as the market develops. Current charging points cost between $8,000 and $12,,000 to manufacture and install and this represents a significant cost which would need to be recouped within any business plan.
