Colder, then warmer: battery operation at varying temperatures
Battery performance can vary greatly under different loads and temperatures. Often it is necessary to start up a device under conditions that are very different from those under which the device will ultimately operate. In this talk we will compare the performance of different lithium primary chemistries over a range of conditions, including mixed temperatures, with a focus on high power and pulsed discharge.
