Abstract

Se provee una pila electroquímica recargable que tiene un aparato que responde a la presión para establecer un punto para la terminación de la carga. En particular, es posible disponer un conmutador que responde a la presión, reversible, en una tapa en la extremidad abierta de una pila recargable de hidruro de metal. El conmutador que responde a la presión, reversible, puede también contener un sistema de venteo para liberar la presión interior de la pila. Como alternativa, una pila recargable puede incluir un medidor de deformaciones dispuesto en su superficie exterior cuya resistencia eléctrica varía a medida que se expande la superficie exterior de la batería debido a la acumulación de la presión interior durante la carga. Adicionalmente se utiliza una pila recargable en comunicación con una fuente de carga que puede proveer un voltaje constante, una corriente constante, una corriente alterna, o un voltaje que varía entre un umbral mínimo y un umbral máximo.
