Testing a Lithium Ion Battery as a Pulsed Power Source

Experiments were performed on a prototype very high power lithium-ion battery cell from Saft Batteries for its pulsed power capacity. The experiments were centered on a series of tests designed to exercise the battery for maximum power transfer and maximum charge/current transfer from battery to a load. The pulsing periods ranged from 0.5 ms to 50 ms. The maximum power obtained was 14.6 kW/kg for a 5 ms pulse. Battery output current measured at 5000 A was obtained for a 5 ms pulse under a 245 Omega load.
