摘要:
A charging regulator assembly for an energy storing device includes an active material actuator configured to move a contact from a connected position permitting current transfer between the contact and a power bus into a disconnected position preventing current transfer between the contact and the power bus. The active material actuator is engaged in response to a temperature of the active material actuator rising above a pre-determined value. Moving the contact into the disconnected position prevents further current transfer into or out of the energy storing device, thereby preventing further heating of the energy storing device and preventing potential damage to the energy storing device form overheating.

An energy harvesting system comprises a first region and a second region having a temperature difference therebetween. A plurality of heat engines are located proximate to the conduit and configured for converting thermal energy to mechanical energy. The heat engines each include a shape memory alloy forming at least one generally continuous loop. The shape memory alloy driven to rotate by heat exchange contact with each of the first region and the second region. At least one pulley for each of the plurality of heat engines is driven by the rotation of the respective shape memory alloy, and each of the at least one pulleys is operatively connected to a component to thereby drive the component.
