A123 Systems is targeting the emerging stop-start/microhybrid market with a 12V Li-ion battery solution based on its automotive class lithium ion AMP20 20 Ah prismatic pouch cells. The system comes equipped with battery management electronics for cell balancing and protection.
Compared to lead-acid AGM batteries used in such applications, the Li-ion batteries offer better charge acceptance, ultimately resulting in lower alternator loads on the engine and better fuel economy; lighter weight (about 60% less than comparable lead-acid batteries); and longer life, according to Jeff Kessen, A123’s VP of Automotive Marketing and Communication.
In addition to the two posts on the 12V package, the battery has a communication connector to the vehicle controller...
