The electrical characteristics of the loads to be faced by the power source are given. Two loads are inductive-resistive; one to be brought to a specified flux in the inductor and one to be brought to a specified energy in the inductor within stated time limits which are of the order of milliseconds. The third load is capacitive-resistive and the capacitor is to be brought to a specified voltage in a period of seconds. Charge (a few Coulombs) and energy (about 10{sup 5} Joules) requirements of the loads are modest compared to the capabilities of common automotive batteries; however, the average power demands of the loads are high (25 to 50 MW or higher for the inductive-resistive loads). Source voltages required to drive the specified loads are much larger than those of common batteries. The literature indicates that the way to achieve the required voltages at high power density and specific power is to utilize thin cell bipolar batteries, a bipolar design offers potential advantages of low cell resistance and weight, and uniformity of electrode current density. 123 refs., 31 figs., 3 tabs.
