摘要： A multi-cell battery pack in an electric vehicle is monitored by multiple sensing modules. A primary controller is coupled to a first plurality of cells to measure a predetermined parameter of each cell. The primary controller determines a sampling moment recurring at a fixed frequency for sampling the predetermined parameter of each of the first plurality of cells. The primary controller generates a sync pulse at each sample moment. A secondary controller is coupled to a second plurality of cells to measure the predetermined parameter of each cell. The secondary controller receives the sync pulse to start a pulse generator operating at a frequency which is a predetermined multiple of the primary controller fixed frequency. The secondary controller counts pulses generated by the pulse generator and schedules a synchronized secondary sampling moment according to a predetermined pulse count.

摘要： A vehicle has a battery including a plurality of cells connected in series, and a battery management integrated circuit including a plurality of inputs each being directly electrically connected to a terminal of one of the cells via an electrical path that includes a thse and a resistor connected in series. The battery management integrated circuit farther includes a top input directly electrically connected to a positive output of the battery and configured to receive power from the battery that is defined by a current having a magnitude that is at least an order of magnitude greater than current received by the inputs and a voltage equal to a sum of voltages of all the cells. The battery management integrated circuit is configured to calculate a voltage difference between one of the inputs and an adjacent one of the inputs to determine a voltage of a top cell of the battery cells and to correct the voltage of the top cell to farm a corrected voltage as a sum of the voltage of the top cell and a calculated voltage drop across the fuse in the electrical path between the top cell and the one of the inputs. The vehicle further has a controller programmed to balance the cells according to the corrected voltage of the top cell.

摘要： A vehicle includes a traction battery and a battery management system. The battery management system includes a controller programmed to output a drained cell diagnostic indicator. The drained cell diagnostic indicator is based on a magnitude of a difference between an average cell state of charge at a start of a battery rest period and a cell state of charge estimated at predetermined intervals during the battery rest period being greater than a predetermined value. A response to the drained cell diagnostic indicator depends on the magnitude of the cell drain rate and may include operating the traction battery at a reduced power level and notifying an operator of the diagnostic condition.
