Electric vehicle batteries
Positioning this technology in the
Functionality Grid
Reformatted from: Van Wyk, Rias J: Technology - A Unifying Code, 2004, SMG, Cape Town, p.34. Based on: Ropohl, Gunter: Eine Systemtheorie der Technik, 1979, Carl Hanser Verlag, Munich and Vienna, p.178.
This Newsbrief deals with the development of batteries for electric motor cars. It reviews different approaches to battery technology. In terms of the Atlas of Technological Megatrends it is concerned with the functionality of energy storing.
At present there is a strong interest in electric motor vehicle development. The U.S. government is providing stimulus funds for this activity. In Europe the German Government wants to see 1 million electric vehicles on the road by 2020. There is a strong drive to more effective batteries.
At present this quest is leading in two directions:
  • New and specialized batteries for electric vehicles
  • Using readily available batteries, but in a system dedicated to vehicles
There are many examples of the first approach. These include partnerships between well known auto manufacturers like GM, Ford and Volkswagen, and battery manufacturers. Recently Hitachi reported a new Lithium Ion battery. (Roy, Rex, 2009, "GREEN: New Batteries: The Quest For More Power - Hitachi Lithium Ion Battery" Automobile Newsletter, October 1, 2009).
But there is another approach - readily available batteries. Tesla Motors follows this route. It uses a standard 18650 format (18 mm in diameter and 65 mm long) originally conceived for cell 'phones and laptops. (Berdichevsky, G.; Kelty, K.; Straubel, J.B.; and Toomre, E.: The Tesla Roadster Battery System, Tesla Motors, August 16, 2006). This is attracting industry attention. In April 2009 Daimler acquired an estimated 10 percent stake in Tesla
Technology explorers should also be on the alert for focused initiatives on lithium extraction and manufacture. One example is American Lithium Minerals (Nasdaq: AMLM) that focuses on battery grade lithium carbonate.
