Hybrid Thermal Battery Reserve Power Source

摘要

A method for producing power from a thermal battery having a piezoelectric generator. The method including: initiating the thermal battery when the thermal battery experiences a predetermined acceleration event; generating power from the piezoelectric generator when the thermal battery experiences the predetermined acceleration event for at least an initial period after the predetermined acceleration event; and generating power from the thermal battery after the initial period.

主权项

1. A thermal battery comprising:
a casing; a battery cell disposed in the casing; a pair of electrical leads extending from the casing and electrically connected to the battery cell; a heat generating pyrotechnic material, separate from the battery cell, at least partially surrounding the battery cell; an inertial starter disposed in the casing for at least activating the battery cell upon the casing experiencing a predetermined acceleration event; and insulation disposed between the heat generating pyrotechnic material and the casing.
