EnerDel Li-Ion Batteries for HEV Applications

EnerDel, a subsidiary of Ener1 Inc., has received outstanding results from independent laboratory tests of its lithium-ion battery cells for hybrid electric vehicles. The battery cells were tested for power-assist goal performance, including tests for static capacity, hybrid pulse power, self-discharge and thermal performance at various temperatures. The initial test results show that its cells met and exceeded phase-one performance goals of the U.S. Advanced Battery Consortium (USABC) contract.

The cells averaged 50% more discharge power compared to the end-of-life target and also had a significantly lower self-discharge. They exhibited consistent discharge results over wide temperature ranges, including very good low temperature performance. This month, the batteries will be tested additionally for high hybrid pulse power characterization, cold cranking, efficiency and lifetime performance.

EnerDel is working under a 12-month, cost-share contract from USABC as part of a proposed three-phase plan to launch a cost-competitive Li-ion battery that is lighter, smaller and higher in power than existing battery technologies for hybrid electric vehicles.
