摘要： A device is configured to receive, from a controller, an instruction requesting data for the device and determine a comparison result value based on a comparison of the data for the device and a reference value. The device is further configured to determine whether to respond to the instruction based on the comparison result value and, in response to a determination to respond to the instruction, output, to the controller, the comparison result value, wherein, to output the comparison result value, the device is configured to refrain from outputting the data for the device.

摘要： A battery cell circuit of a battery management system configured to receive, from a previous battery cell circuit of a plurality of battery cell circuits connected in a daisy chain configuration or ring configuration, an instruction requesting a value for the battery cell circuit and determine a comparison result value based on a comparison of the value for the battery cell circuit and a reference value. The battery cell circuit is further configured to output, to a controller, the comparison result value, wherein, to output the comparison result value, the battery cell circuit is configured to refrain from outputting the value for the battery cell circuit.

摘要： In some examples, this disclosure describes a method of operating a plurality of battery management circuits of a battery management system associated with an electric device. The method may comprise adjusting a first trim value associated with a first battery management circuit during operation of the electric device, and adjusting a second trim value associated with a second battery management circuit during operation of the electric device. The method may also comprise sinking a first amount of current in the first battery management circuit based on the first trim value; and sinking a second amount of current in the second battery management circuit based on the second trim value, wherein sinking the first amount of current and sinking the second amount of current causes the first battery management circuit and the second battery management circuit to consume substantially similar amounts of current.

摘要： A method for monitoring a particular battery cell among a plurality of battery cells may be performed by a battery monitoring circuit, wherein a supply wire from a supply circuit and a voltage measurement wire of a battery management circuit comprises a shared path for the particular battery cell. The method may comprise performing a first voltage measurement associated with the particular battery cell; performing a second voltage measurement associated with the particular battery cell and an additional element; and determining a cell voltage associated with the particular battery cell based on the first voltage measurement and the second voltage measurement.
