Abstract
A battery management system with synchronized data sampling for a battery pack including multiple battery cells is disclosed. The battery management system includes a plurality of local monitors coupled to a plurality of battery cells and operable for sampling status information for the battery cells. The battery management system further includes a central controller coupled to the local monitors and operable for broadcasting a sample command to the local monitor synchronously, wherein the local monitors start to sample the status information for the battery cells in response to the sample command.
Claims23
