  • Patent number: 12062256
    Abstract: Disclosed herein are a method and a device for remotely diagnosing vehicle faults, a vehicle and a computer storage medium. The method includes monitoring vehicle data uploaded by the vehicle in real time via a cloud platform, and determining whether to identify a preset fault abnormal signal identification from target data of the vehicle data. The method also includes, in response to the fault abnormal signal identification being identified from the target data, sending a fault diagnosis task to the vehicle according to the target data, and receiving diagnosis result data returned by the vehicle after the fault diagnosis task is executed locally by the vehicle. The method further includes generating a remote fault diagnosis result of the vehicle according to the vehicle data and the diagnosis result data.

  • Publication number: 20240034150
    Abstract: Disclosed herein are a vehicle thermal runaway warning method, device, electronic equipment and readable storage medium. The method of vehicle thermal runaway warning includes obtaining operating data of a vehicle, the operating data including a plurality of cell voltage data of a battery pack in the vehicle, and dividing time windows for the plurality of cell voltage data according to a collection timing of the operating data. The method also includes extracting cell voltage characteristics from a partial cell voltage data corresponding to each of the divided time windows. The method further includes, in response to each cell voltage characteristic meeting a preset voltage warning condition, determining that the vehicle has a risk of thermal runaway, and controlling the vehicle to output thermal runaway warning information.
