Abstract

"SISTEMA E MéTODO DE ESTIMATIVA DE CAPACIDADE DE BATERIA". São providenciados sistemas e métodos para uma estimativa de capacidade de bateria. Uma tabela de perfil referente à pluralidade de valores de perfil de bateria com uma pluralidade de valores de parâmetros operacionais pode ser usada; a tabela de perfil pode ser acessada para traduzir um ou mais parâmetros operacionais medidos em um ou mais correspondentes valores de perfil de bateria; um ou mais dos valores de perfil de bateria podem ser ajustados por um fator de correção para gerar um valor de perfil de bateria corrigido; a capacidade disponível da bateria pode ser calculada usando o valor de perfil de bateria corrigido; o fator de correção pode ser, então, automaticamente, calibrado, usando um valor de perfil de bateria estimado calculado a partir de um ou mais parâmetros operacionais medidos; em adição, podem ser executados os passos do método seguinte; determinar um valor de resistência de série equivalente para a bateria; determinar um valor de tensão de carga para a bateria; determinar um valor de corrente de carga para a bateria; determinar o valor de tensão não descarregado como uma função do valor de resistência de série equivalente, o valor de tensão de carga e o valor de corrente de carga.
