Abstract

"DISPOSITIVO DE CáLCULO CALCULANDO CAPACIDADE DISPONìVEL DE BATERIA SECUNDáRIA E MéTODO PARA CALCULAR A MESMA". Um método para calcular uma capacidade disponível inclui as etapas de: calcular um primeiro SOC estimado a partir de um valor na voltagem (S100), calcular uma integral de um valor de uma corrente (S100) e adicionar a integral para calcular um segundo SOC estimado (S120); calcular uma diferença entre o primeiro e segundo SOCs estimados (S130); calcular um primeiro coeficiente de correção R(1) a partir do valor na voltagem (S140); calcular um segundo coeficiente de correção R(2) para ser menor para a corrente possuindo um valor menor (S150); e adicionar o segundo SOC estimado para um termo de correção, ou o dSOC multiplicado por R(1) e R(20), para calcular um SOC corrigido (S160).
