Ford Focus EV 2012: Liquid cooling for its lithium-polymer battery

By Daniel Chubb - Sep 4, 2010

Electric vehicles are nothing new nowadays, a lot of people have taken them on board and introduced them into their lives. However as quickly as a new thing has been designed then another is on the drawing board.

This is the case with the 2012 Ford Focus set for debut later on this year. Along with its LG Chem lithium polymer battery cells ( yes it is abit of a mouthful ), Ford says that its EV will also be fitted with a liquid-cooled pack with auto thermal management as fitted to the Chevrolet Volt.

The introduction of this type of electronic cooling, will extend the batteries lifespan and also help to gain the maximum performance. By keeping the cells cool the active thermal management will be able to prevent the likelihood of cracks in the electrodes. These cracks can start to effect the batteries power and reduce the charge capabilities. On initial plug-in the management system will run a precondition of the batteries before it allows charging to begin.

With the increase in the development and design of electrically powered vehicles, it seems that the only large manufacturers continuing to use passive air cooling for their EV’s is Nissan and Mitsubishi. Having said that Nissan is offering an eight-year warranty on its models, although its still to be seen as to how the cells will fair through continuous use.
