Industry study finds lead-acid to remain most wide-spread automotive energy storage for foreseeable future; new chemistries continue to grow

Green Car Congress

Advanced lead-based batteries (AGM and EFB technologies) are installed to meet extra requirements in start-stop and basic- micro-hybrid vehicles, due to their increased charge recoverability and higher deep-cycle resistance. In full-hybrid vehicles, the stored energy is also used for a certain range of electric driving.

While they store a high amount of energy compared to the other designs, their power output is comparatively low. Under a venture with the motto “From Road to Grid”, Audi is therefore currently working on a concept to convert old batteries into stationary energy stores. Pouch cells and prismatic cells are more versatile.

Vehicle-to-Grid (V2G) is the concept of using stored energy in a plug-in hybrids (or electric cars) battery to send power to the electrical grid when necessary. Many continue to pay more attention to far-off hydrogen fuel cells than to this immediate solution. Whats Vehicle-to-Grid and why would I like it? Are the batteries recyclable?
