| description | The invention discloses a cell-by-cell monitoring multi-loop hierarchical control battery management system of an electric vehicle. The battery management system comprises a main controller, hierarchical controllers and unit detectors. The main controller is electrically connected with a whole-vehicle control system through a first-stage CAN bus. The main controller is electrically connected with the hierarchical controllers through a second-stage CAN bus. The plurality of hierarchical controllers are electrically connected with plurality of unit detectors through a third-stage CAN bus. The plurality of unit detectors are electrically connected with a plurality of cells in a one-to-one manner. The cell-by-cell monitoring multi-loop hierarchical control battery management system of the electric vehicle has beneficial effects of realizing multi-loop hierarchical control, realizing single cell detection, realizing high-efficiency bidirectional dynamic active balance, prolonging duration distance, improving servi |
