Fluid Manager Using Two Shape Memory Alloy Components and a Battery Including the Same

摘要

A fluid consuming battery ( 10 ) is provided with a fluid regulating system ( 50 ) for regulating fluid entry into the battery. The battery ( 10 ) includes a fluid consuming cell ( 20 ) having a cell housing with fluid entry ports for the passage of a fluid into the cell housing. A first fluid consuming electrode and a second electrode are disposed within the cell housing. The fluid regulating system ( 50 ) includes a valve having a moving plate ( 66 ) disposed adjacent to a fixed plate ( 62 ). The moving plate and fixed plate both have fluid entry ports ( 68, 64 ) that align in an open valve position and are misaligned in a closed valve position. The fluid regulating system ( 50 ) also includes an actuator that may include one or more shape memory alloy (SMA) components ( 82 a, 82 b) for moving the moving plate ( 66 ) relative to the fixed plate ( 62 ) to open and close the valve.
