Electric vehicles (EVs) take hours after hours to get fully recharged. But lately, engineers from BMW and General Motors (GM) have announced that people will be able to recharge 80% of their electric vehicles (EV) just in 20 minutes using a DC Combo Fast Charger developed by the Society of Automotive Engineers (SAE).
The combo connector adds two large pins below the existing five-pin AC socket to support direct current charging at up to 480-volts. Vehicles using the new connector can still hook up to existing Level 2 AC chargers at 240-volts with the original 5-pin connector. However the latest round of tests has confirmed that a battery can be replenished up to 80 percent of capacity in 20 minutes.
Britta Gross, GM’s director of advanced vehicle commercialization policy said, “The DC Combo quick charger changes the game. Imagine stopping off for a cup of coffee, plugging in your vehicle at the fast charge station outside, run in for your cup of coffee, 10 minutes, 20 minutes later, you have a fully charged vehicle.”
BMW and GM will be the first two companies to adopt the DC Combo Fast Charge stations in BMW i3 and the Chevrolet Spark EV respectively. The i3 will be delivered later this year, while Chevy is set to debut the Spark EV this month. On the other side, apart from these two companies – Ford, Chrysler, Daimler, Volkswagen, Audi and Porsche – all plans to use this new connector for their upcoming electronic vehicles.
