Abstract

modalidades da presente invenção fornecem um método de proteção de carga, que inclui: medir (s101) uma tensão de carga, uma corrente de carga e um aumento da temperatura de uma interface de carga de um dispositivo carregado; detectar (s102) se a tensão de carga cai além do limite de uma faixa de tensão predefinida, detectar se a corrente de carga é menor do que um limiar de corrente predefinido e detectar se o aumento da temperatura é maior do que um limiar de aumento de temperatura predefinido; e se um resultado de detecção de qualquer um ou mais dos três itens for positivo, desconectar (s103) um circuito de carga de um carregador. de modo correspondente, as modalidades da presente invenção fornecem adicionalmente um aparelho de proteção de carga que pode desconectar um circuito de carga em tempo hábil quando uma exceção de carga ocorre, dessa forma, evitando dano a uma interface de carga.
