Battery swapping was once hailed as the miracle cure for short-range electric cars, but the trials and tribulations of Better Place have shown that isn't necessarily the case.
It's not a bad idea though--it just needs the correct application.
That could be in the commercial vehicle world, as demonstrated by the GreenWay Project in Slovakia.
As you'll immediately gather by watching the video above, the GreenWay Project's setup isn't nearly as grand or as slick as Better Place, but that could also be its advantage.
A small fleet of Citroen vans has been converted to electric power, their batteries taking the shape of a conspicuously large black box taking up some of the load bay.
Cleverly, this large pack sits on a rail system. When stopping at one of the Project's swap stations, the old battery can be disconnected (via a simple lever), slid onto a forklift, and another battery slid into place.
It does render the side door rather useless for any other purpose than battery swapping, but the whole process takes only seven minutes (once you've got the technique down, naturally), far shorter than stopping to recharge. It's around the same amount of time a driver might stop to fill up a regular van with diesel or gasoline. A realistic daily distance of over 155 miles is said to be achievable with the system.
The company intents to build up its own network of these swapping stations, integrating a network of electric vans, charging and swapping stations, information, servicing and backup and the electricity itself--everything a company might need to run a fleet of vehicles.
GreenWay is heavily pushing the environmental aspect, but the ease of use and cost benefits too.
It's too early to tell whether it'll take off, but commercial markets are quite different from that of private individuals. Is this where battery swapping will find its niche?
