Abstract

Se provee un método para estimar el estado de carga de un paquete de baterías que tiene una o más celdas. El método incluye obtener, mediante un controlador de batería del paquete de baterías, datos de un dispositivo acoplado eléctricamente al paquete de baterías. Los datos son indicativos del requisito de energía para el dispositivo. El método puede incluir además determinar, mediante el controlador de batería, el estado de carga del paquete de baterías en base, por lo menos en parte, en los datos indicativos del requerimiento de energía para el dispositivo.
