Abstract
Procedimiento para la determinación de la corriente de carga (IL) y de la temperatura (T) de un acumulador, caracterizado porque una parte de la corriente de carga (IL) es amplificada a través de un transistor (V), que está en contacto térmico con el acumulador, se mide una vez una tensión de salida (UA) del circuito amplificador de transistor para la determinación de un valor de referencia (UA, Ref) a una temperatura conocida (T0), a continuación a la temperatura (T) a determinar, con la corriente de carga desconectada, se mide la tensión de salida (UA, O) y a la misma temperatura se mide la tensión de salida (UA, I) con la corriente de carga (I) conectada y a continuación a partir del valor de referencia (UA, Ref), de la tensión (UA, O) con la corriente de carga desconectada y de la tensión (UA, I) con la corriente de carga conectada, se determinan por cálculo la temperatura (T) y la corriente de carga (I).
