Brisk development of fast-charging technologies for electric vehicles will result to installation of around 199,000 fast-charging stations around the world by 2020, according to a study by IHS Automotive. That would be over 100 times the number of the fast-charging stations in 2012. IHS said in the study that number of fast-charging stations globally may jump to 5,900 in 2013 and to 15,200 in 2014. Fast-charging stations provide a high-voltage DC charge, allowing customers to charge their vehicles as fast as 20 minutes. Alastair Hayfield, associate research director at IHS Automotive, said in a statement that the length of time it takes to recharge an EV remains one of the major hurdles that inhibit the “widespread adoption” of electric vehicles.
He said that compared to time needed to refuel a conventional vehicle, the recharge time for EVs is “incredibly slow.” It takes around four hours to charge a 24 kWh battery using a 6.6 kW on-board charger. According to Hayfield, if EV makers could overcome this hurdle, this could lead to a “high rate of adoption” from environmentally minded consumers and from consumer saving on gasoline expenses.
IHS expects around 800 fast-charging stations in the US by end of 2013. There are currently three emerging fast-charging standards. One of them is CHAdeMO, which is supported mainly by Japanese carmakers. Many US and German carmakers support the Combined Charging System, or Combo while Tesla has its own Supercharger system.
“The length of time it takes to recharge an EV continues to be one of the major stumbling blocks inhibiting the widespread adoption of electric vehicles,” said Alastair Hayfield, associate research director at IHS Automotive. “Compared to the time it takes to refuel an internal combustion engine (ICE) vehicle, the recharge time for EVs is incredibly slow—at about four hours to charge a 24 kilowatt-hour (kWh)-capacity battery using a 6.6 kW on-board charger. If EV auto manufacturers could overcome this obstacle, it could lead to a high rate of adoption from environmentally minded consumers as well as those seeking to cut gasoline expenses. That’s where fast charging comes in.”
