Abstract

"SISTEMA PARA PROTEçãO PARA DESCARGA DE BATERIA PARA UM DISPOSITIVO MóVEL DE TELECOMUNICAçõES ENERGIZADO POR UMA BATERIA, E, PROCESSO PARA IMPEDIR QUE UM DISPOSITIVO DE TELECOMUNICAçõES DESCARREGUE PROFUNDAMENTE UMA BATERIA EM UM VEìCULO QUANDO O VEìCULO NãO ESTá CARREGANDO A BATERIA" A presente invenção mede o consumo de energia de dispositivos telefónicos energizados por bateria, para impedir a descarga profunda da bateria de um veículo por utilização prolongada de ditos dispositivos, quando o veículo está desacompanhado. Em uma configuração preferencial, a corrente para os dispositivos é medida de forma incremental ou estimada a partir de uma medição de outros parâmetros relevantes. As medições de forma incremental da corrente são acumuladas para produzir um consumo total decorrente, indicador do consumo total de energia. A cada atualização depois de uma medição incremental, o total acumulado é comparado com um limiar pré-estabelecido ou determinado de forma adaptada, o qual estabelece um limite na extensão até a qual o acessório é deixado descarregar a bateria. Quando o consumo total de energia atinge ou excede o limiar, a energia para o dispositivo telefónico energizado por bateria é interrompida para conservar uma quantidade suficiente de energia para dar partida no veículo e para operar outros sistemas periféricos.
