    摘要： The present invention relates to a battery management system and method. In some embodiments the battery management system includes a sensing unit and a micro controller unit (MCU). The sensing unit measures the current, the voltage and the temperature of a battery. The MCU receives the voltages, the currents, and the temperatures, calculates an estimated cell voltage, by applying a pack voltage sensing error and the cell voltage deviation to the cell voltages, and calculates an estimated cell resistance, by adding a pack assembly resistance to an internal resistance of the cell, and calculates an pack output of the battery by using the estimated cell voltage and the estimated cell resistance.

    摘要： A battery management system using a measurement model modeling a battery, and estimating a SOC (state-of-charge) of the battery, and a battery driving method thereof. The battery management system is constructed with a sensor, a predictor, a data rejection unit, and a measurement unit. The sensor senses a charging and discharging current flowing through the battery, a temperature of the battery, a terminal voltage of the battery. The predictor counts the charging and discharging current, and estimates the state-of-charge of the battery. The data rejection unit generates information associated with an error generated from the measurement model, as a function of at least one of the battery temperature, the charging and discharging current, the state-of-charge, and a dynamic of the charging and discharging current. The measurement unit corrects the estimated state-of-charge of the battery, using the measurement model and the information associated with the error.

    摘要： The cell barrier for a rechargeable battery module of the present invention includes a metal body and an insulating layer disposed on the surface of the metal body. The cell barrier is interposed between unit cells to electrically insulate between the unit cells. The insulating layer is selected from the group consisting of a resin layer, an inorganic oxide layer, an anodized layer, and a composite layer thereof. The cell barrier also has channels to provide for additional cooling by a heat transfer medium. A single unit cell can also be used with a cell barrier disposed along the unit cell for insulation and cooling.
