Abstract: In accordance with an embodiment, an energy storage system includes energy storage container that a temperature control system, a battery cluster, and a controller. The controller determines a specified temperature of the temperature control system corresponding to a maximum difference between an available capacity of the battery cluster and a power consumption of the temperature control system as a target temperature. The determination of the specified temperature is based on: a correspondence between the available capacity of the battery cluster and a plurality of different specified temperatures in a specified temperature set of the temperature control system, and a correspondence between the power consumption of the temperature control system and the plurality of different specified temperatures in the specified temperature set of the temperature control system. The temperature control system is configured to adjust a temperature inside the energy storage container to the target temperature.

Abstract: A battery safety monitoring system includes a central controller, a fault detection sensor, a flame detection apparatus, and a fire extinguishing apparatus. The fault detection sensor is configured to detect a fault in a target battery module and send fault information to the central controller. The central controller is configured to control the flame detection apparatus to perform flame detection on the target battery module based on the fault information. The flame detection apparatus is configured to send, when detecting a fire in the target battery module, fire information to the central controller. The central controller is further configured to control the fire extinguishing apparatus to start a fire extinguishing operation for the target battery module. There is no need to deploy excessive sensors. Instead, the flame detection apparatus is controlled to perform flame monitoring on the target battery module, to implement low-cost and accurate battery safety monitoring.

Abstract: A cloud-device synergy-based battery management system is provided in this application, which includes a vehicle and a cloud BMS. The vehicle includes a vehicle BMS. The vehicle BMS is configured to: measure a battery parameter of the vehicle, and send first battery parameter data obtained through measurement to the cloud BMS. The cloud BMS is configured to: train second battery parameter data, and send a first training result obtained through training to the vehicle BMS, where the second battery parameter data includes the first battery parameter data and historical battery parameter data. The system implements vehicle battery management through cooperation of the vehicle BMS and the cloud BMS. Further, a vehicle, and a battery management method are also provided in this application.
