1. A hybrid thermal management system comprising:
- a battery;
a capacitor; and
a controller programmed to, responsive to a demand and a temperature being less than an upper threshold, select and operate only one of the battery and capacitor to satisfy the demand according to which of two values, corresponding to traction power dependent heat generation functions representing rates at which the battery and capacitor generate heat, is less to maintain the temperature below the threshold.

Abstract
A hybrid thermal management system includes a battery, a capacitor, and a controller programmed to, responsive to a demand and a temperature being less than an upper threshold, select and operate only one of the battery and capacitor to satisfy the demand according to which of two values, corresponding to traction power dependent heat generation functions representing rates at which the battery and capacitor generate heat, is less to maintain the temperature below the threshold.

12. A hybrid thermal management system comprising:
a controller programmed to, responsive to a state of a battery exceeding a threshold, assign power required from the battery and a capacitor to satisfy a demand of the system based on heat generation functions representing rates at which the battery and capacitor generate heat such that the assigned powers are minimized to minimize heat generation of the capacitor and battery, and responsive to the state being less than the threshold, assign the power such that the assigned powers are maximized to maximize heat generation of the capacitor and battery. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A hybrid thermal management system comprising:
-
a battery; a capacitor; and a controller programmed to assign power required from each of the battery and the capacitor to satisfy a demand of the system, the assigned power being based on a state of at least one of the battery and the capacitor and heat generation functions representing rates at which the battery and the capacitor generate heat such that for a given value of the demand, the assigned power maximizes heat generated by the battery and capacitor when the state is less than a lower threshold and minimizes the heat generated when the state is greater than an upper threshold. - View Dependent Claims (20)
