Abstract

Aparelho para monitorar capacidade e estado relativos de carga entre pelo menos duas células, ou módulos de células, A e B de uma pluralidade de células de Lítio-Enxofre arranjadas em série, compreendendo: um timer; um módulo de monitoramento de tensões configurado para monitorar uma queda de tensão através de cada uma das células ou módulos de células de Lítio-Enxofre arranjados em série com base em sinais recebidos de um circuito de monitoramento de tensões; e um módulo de monitoramento de células acoplado ao timer e ao módulo de monitoramento de tensões e configurado para, durante um ciclo de carregamento no qual as células são carregadas em uma corrente constante: gravar uma etiqueta de tempo T1(Célula A) em que a tensão monitorada da primeira célula, célula A, conduzindo o carregamento alcança uma primeira tensão V1(célula A) definida para estar perto do topo de carga à medida que a taxa de mudança da tensão monitorada aumenta de modo mensurável; gravar uma etiqueta de tempo T1(Célula B) em que a tensão monitorada da célula B seguinte no carregamento alcança a primeira tensão V1(Célula A); gravar uma etiqueta de tempo T2(Célula A) em que a tensão monitorada da célula A de condução alcança uma segunda tensão V2(Célula A) definida para estar substancialmente em um topo de carga suposto; gravar uma tensão monitorada V2(Célula B) da célula B seguinte em T2(Célula A); e determinar, com base pelo menos em T1(Célula A), T1(Célula B), V2(Célula A) e V2(Célula B), uma métrica indicativa de uma diferença de capacidade relativa entre a célula A e a célula B.
