A thermal management method includes obtaining a predicted temperature including a predicted value of an operating temperature of a target device, and controlling the target device to switch a thermal management according to the predicted temperature mode. The thermal management mode is used to adjust the operating temperature of the target device.

Thermal management method and system, domain control unit and storage medium

A storage battery monitoring system and method are provided. The system includes n cell monitoring cells (CMCs), a control module (), and several daisy chain buses. The n CMCs are configured to monitor a plurality of cell modules electrically connected in a storage battery, and each CMC is configured to monitor at least one of the cell modules. The n CMCs are connected to the control module () through each daisy chain bus. The control module is configured to receive monitoring data of the plurality of cell modules uploaded by the n CMCs through a transmission path formed by at least one daisy chain bus. The control module () is further configured to identify a fault location according to the monitoring data when a fault occurring to the transmission path is detected, and adjust the transmission path according to the fault location so as to receive the monitoring data.

Storage battery monitoring system and method

Battery heating systems and methods are provided in the present disclosure. A battery heating system includes: a temperature sampling module configured to collect a target sampling temperature; a first switch configured to be turned on or off based on a driving signal; a control module configured to determine, based on the target sampling temperature and a correspondence between the target sampling temperature and the driving signal, a duration where the first switch is controlled to be turned on and a duration where the first switch is controlled to be turned off, and generate the driving signal; and a heating module configured to heat the battery module set using an output power of the battery module set when the first switch is turned on, and stop heating the battery module set when the first switch is turned off. As a result, fineness of battery heating can be improved.
