This idea was already presented by the Technical University Munic half year ago. They are using a zinc-air battery as a range extender to the primary Lithium-Ion battery. I think, this kind of idea are not be possible to patent (maybe except in america).
Yes - I was about to say the same thing. The patent system is broken here.This idea was already presented by the Technical University Munic half year ago.

US Patent Application 20120041624 - Electric Vehicle Extended Range Hybrid Battery Pack System
Application 20120041624 Filed on December 8, 2010. Published on February 16, 2012
An idea cannot be patented I believe. Only the working prototype. Much more difficult than just having an idea... Here in Canada anyway.
Who knows, maybe they bought the patent, made it better and are filing with the new concept.
When you file a patent in the US, you can ask for publication to be delayed. This is most likely what happened this time. The filing date (8 Dec 2010) is the important one (for protection, as well as invalidation via prior art).
Range extender
There is an additional energy store in the form of a range extender.
The MUTE vehicle concept combines the main Lithium-ion battery with an electrochemical range extender as part of a zinc-air system. Due to its high energy density and low cost, the zinc-air system provides excellent range extension.
That sounds fairly quick, actually. I've had a patent take three years to get processed.
This is the first filing, and no change to listed inventors.
