Abstract

aparelho para modelar um estado de carga e método para estimar um estado de carga trata-se de sistemas e métodos para determinar de modo preciso o estado de saúde (que inclui o estado de carga e a idade relativa) de uma bateria, módulo ou célula de lítio-enxofre. a invenção usa um modelo operacional de uma célula ou bateria de lítio-enxofre para prever parâmetros de modelo sob uma faixa de condições relacionadas ao estado de carga e ao estado de saúde. os modelos operacionais incluem o efeito de memória devido à composição química única de uma célula de lítio-enxofre que impede o uso de outras metodologias para a determinação do estado de saúde para baterias de lítio-enxofre. os parâmetros de modelo são identificados em aplicações da vida real e os parâmetros são comparados àqueles do modelo operacional de lítio-enxofre que emprega filtragem de kalman. a saída inclui uma estimativa do estado de saúde e outros indicadores chave de desempenho. os indicadores chave de desempenho são comparados com valores medidos, por exemplo de resistência, para fornecer retroalimentação ao processo de estimativa a fim de melhorar a precisão. o sistema pode ser implantado como software ou firmware em um aplicativo.
