Abstract
MÉTODO DE CONTROLE DE EQUALIZAÇÃO DE CARREGAMENTO/DESCARREGAMENTO, COMPONENTE DE BATERIA E SISTEMA DE CONSUMO DE ELETRICIDADE. Este pedido fornece um método de controle de equalização de carregamento/descarregamento, um componente de bateria e um sistema de consumo de eletricidade. O componente de bateria inclui M módulos de bateria, os M módulos de bateria são conectados em paralelo e M é um número inteiro positivo maior que 1. Cada módulo de bateria inclui uma unidade de controle, um conversor DCDC e uma unidade de armazenamento de energia. A unidade de controle é eletricamente conectada ao conversor DCDC, e o conversor DCDC é ainda eletricamente conectado a uma carga e/ou uma fonte de potência. Para cada módulo de bateria, o método inclui: a unidade de controle determina um valor de referência de um parâmetro de potência, onde o valor de referência é usado para equalizar carregamento/descarregamento dos M módulos de bateria; e a unidade de controle controla, usando o conversor DCDC, um valor real do parâmetro de potência para ser igual ao valor de referência. Isso implementa carregamento/descarregamento equalizado de M módulos de bateria e implementa ainda uma potência em paralelo de módulos de bateria com diferentes capacidades no componente de bateria, de modo a resolver um problema em uma tecnologia relacionada que um alto requisito é imposto em consistência de pacotes de células em módulos de bateria porque os módulos de bateria são usados em paralelo.
