Abstract: A consumer electronic device includes a battery module and a system chip. The battery module includes: battery cells, a heater adjacent to the battery cells, a battery management circuit coupled to the battery cells and the heater, and an electrical connector including an information transmission interface and a power transmission interface. The information transmission interface is coupled to the battery management circuit, and the power transmission interface is coupled to the battery cells. The system chip is coupled to the information transmission interface, and is configured to receive battery information from the battery management circuit through the information transmission interface. When a battery temperature of the battery information is lower than a first threshold, the system chip sends an activation signal to the battery management circuit through the information transmission interface, for the battery management circuit to activate the heater according to the activation signal.
