Performance improvement of a small car with LiFePO4 batteries

In 2009, a presentation was done in PCIM about the experience feedback on electric vehicles of the French car fleet and the cost of battery use in this application. The initial expensive price of NiCd batteries, combined with poor cycles endurance, induce a kilometric cost two to three times higher than the one of traditional gasoline vehicles. The replacement of the initial NiCd battery of an AX vehicle by an iron phosphate Lithium battery with 1600 small cells was presented in conclusion [1]. This presentation is focalized on the improvements of the vehicle performance due to this power iron phosphate Lithium ion battery.
