Right now, refilling your electric vehicle is quite a timely process. Even the best EV charging systems can take several hours to fully charge a depleted battery, and while this might be fine and dandy for commuter cars, it makes living with an electric car as a daily driver a bit more difficult.
But fast charging stations are coming, and could be a real game changer. Coulomb Technologies and Aker Wade are teaming up their technologies to bring a “Level III” charging stations to the world later this year. These stations could charge an electric car in as little as 15 minutes. Now that’s impressive.

Sven Holthusen runs the EDISON project at Siemens’ Energy Sector in the Denmark branch of the international engineering giant. The EDISON project is working on raising charging power to as much as 300 kW so that batteries can be recharged on the go, in as little as six minutes.
The idea is to replicate the familiar: filling up at a gas station in 6 minutes or so, not in order to replace long slow overnight charges in home garages but to have an alternative to meet the needs of those apartment-dwellers who don’t have garages (and those who do, but who don’t sleep at least 6 hours at night) by making on-the-go-charges as available and as quick as filling up at a gas station.

In a slew of announcements this week, a picture of what the future of plug-in vehicle charging might look like is starting to emerge.
The Problem:
There are 54 million garages for the 247 million registered cars in the US, meaning that the majority of cars are parked overnight in parking structures, parking lots or curbside.
As a result, most potential plug-in vehicle consumers do not have an adequate place to charge their vehicles. This problem is even more pronounced in urban areas like San Francisco, where only about 16% of cars are parked in garages overnight and the rest end up curbside or in parking lots.
Also, although the US power grid probably has enough overall capacity to supply energy to a nation of plug-in vehicles, it may not have the ability to charge them when they all plug-in and demand energy at the same time — say 6 pm every weekday.
