When our regular car’s tank get empty, it takes average 7 or 8 minutes to fill it up, but if it is an electric car this will take a while. Think you need to wait hours to get on the road again. EPGL (Energy Center and Industrial Electronics Lab ) researchers have found a way to charge your car, way faster than the charging technology today. The reason behind that we can not a charge a plug-in car not fast enough is the ” power grids “. Battery technology is improving every day they can be charge ten times faster than today. But how can a power grid can charge hundreds of cars at the same time and in a fast way. The researchers come up with “intermediate storage” idea that can solve this problem and perform an ultra-fast charging.
Don’t Miss: Thanks to This New Tech, No More Battery Fires or Explosions
If we put gas in a regular car just 90 seconds, it will go hundreds of miles before needing a refill, but an electric car that charges just 90 seconds, will able to go just about 4 miles ( 6 km ). So if we want to charge the plug-in vehicle we need to increase the power flow, for this charger needs to transfer 4,5 MW power at once, it is almost equal to power up 4,500 washing machines. This kind of electric flow would bring down the power grid.
EPFL ( Energy Center and Industrial Electronics Lab); came up with an idea to solve this issue. They build the giant lithium-ion battery that size of a shipping container ( intermediate storage ) that charge by regular grid line which is also be connect with our homes. But when an all-electric car or plug-in vehicle need a fast charge, this big lithium-ion battery disconnect itself from the city grid line and perform an ultra fast charging. The team’s future predict is. Future fast charging stations will able to fast charge 200 cars per day, and intermediate storage capacity can be 2.2 MWh, this much power almost equal to a typical house’s one year electrical needs.
Fast charging is one of the serious problems of the all-electric cars. One of the reasons they can not be easily used in big cities. But with this technology and other new technologies that certainly will come shortly, the hands of the plug-in cars will get stronger. We will see what will happen next.
