Abstract

resumo patente de invenção: "sistema de bateria". adicionalmente a um desvio de concentração de íons entre eletrodos, outros fatores influenciam o estado de degradação e o estado de carga de uma bateria secundária. esse sistema de bateria inclui uma bateria secundária (1) que é submetida ao carregamento e descarregamento; e um controlador (300) que estima a taxa de degradação ou o estado de carga da bateria secundária. ao estimar o estado de degradação ou o estado de carga, o controlador utiliza a concentração média de íons entre um eletrodo positivo e um eletrodo negativo. a concentração média de íons varia dependendo da corrente elétrica que flui através da bateria secundária. a concentração média de íons entre eletrodos pode ser calculada com o uso de uma expressão aritmética que inclui a pressão de superfície da bateria secundária como uma variável. a pressão de superfície da bateria secundária pode ser detectada com o uso de um sensor de pressão. a pressão de superfície da bateria secundária pode também ser estimada a partir da corrente elétrica que flui através da bateria secundária.
