It appears that along with re-engineering the powertrain of their upcoming electric vehicles Phoenix Motor Cars has decided to hedge their battery bet. Phoenix was the first company to commit to using Altairnano's lithium titanate batteries in an automotive applications. However Canadian battery supplier Electrovaya announced the other day that they would be supplying battery packs to Phoenix. The obvious question is what becomes of Altairnano? According to Phoenix Marketing VP Bryon Bliss, the company will be offering packs from multiple suppliers. Both Altairnano and Electrovaya batteries will be sold for the upcoming SUV and sport utility truck. The Altairnano batteries have the advantage of being able to withstand 10 minute rapid charges. Unfortunately they only have about half the energy density of other lithium battery technologies and so far they are also much more expensive. We're still trying to get more clarification on timing and cost differences for the different battery packs and we'll keep you updated.
