You might soon pump electrons like gasoline

This article is talking about a fairly old technology: the flow battery.  It can be recharged by connection to the grid, or by replacing used electrolyte.  Existing flow batteries are so large that they are only practical for stationary applications.

Holden Commodore EV

In its January 2012 edition, the Australian motoring magazine, Wheels, has a progress report on the EV Engineering consortium project to develop an EV Holden* Commodore.  The consortium consists of Bosch, Continental, Air International & GE.  Holden is providing engineering support & use of its Lang Lang testing facility.  Funding has been provided, in part, by the Australian Federal Government in the sum of $A3.55 million.
  • Similar performance to a 6 cylinder Commodore.
  • Range 160 km.  Real world 80-140 km.
  • Battery in the space previously occupied by the engine, transmission & driveshaft.  In the current fitting, it is bolted from below, although a Better Place compatible quick swap system is in development.
  • Electronics replace the fuel tank.
  • Motor is attached to a modified rear subframe.  Standard mounting points are retained
  • 150 kg added mass, though little change in weight distribution.
  • Heating is provided by the standard Commodore heater with the assistance of a small, electric water heater.
  • Quite a bit of room remains under the bonnet, although the fuel tank has been removed, so a range extender will be problematic.
Holden is "interested", although a commercial product marketed by them is highly unlikely with the Volt extended range EV planned for release late in 2012.

* Holden is General Motors in Australia.
