Abstract

Un paquete de baterías puede incluir una o más celdas. El paquete de baterías puede incluir por lo menos un sensor de temperatura configurado para obtener una medición de temperatura indicativa de la temperatura de por lo menos una celda de la una no más celdas. El paquete de baterías puede incluir un controlador, el controlador configurado para ser colocado en comunicación de señal con un cargador de batería. El controlador se puede configurar para efectuar operaciones. Las operaciones pueden incluir obtener la medición de temperatura del por lo menos un sensor de temperatura. Las operaciones pueden incluir determinar, en base por lo menos en parte en la medición de temperatura, que la temperatura de la por lo menos una celda está entre un umbral de temperatura inferior y un umbral de temperatura superior. Las operaciones pueden incluir, en respuesta a determinar que la temperatura de la por lo menos una celda está entre el umbral de temperatura inferior y el umbral de temperatura superior, reducir la corriente de carga máxima, en donde reducir la corriente de carga máxima comprende reducir la corriente de carga máxima en base por lo menos en parte en una relación funcional inversa entre la medición de temperatura y la corriente de carga máxima. Las operaciones pueden incluir controlar el cargador de batería en base, por lo menos en parte, en la corriente de carga máxima para cargar una o más celdas.
