    摘要： A sensing and control apparatus for a battery management system is provided. The sensing and control apparatus includes: a sensing unit and a main control unit. The sensing unit includes: a cell relay of a plurality of cell relays and a voltage detection unit. The cell relay is configured to be coupled to at least one of a plurality of cells. The voltage detection unit is coupled to a cell relay. The voltage detection unit is configured to: receive a reference voltage when each of the plurality of cell relays is turned off; and generate a second voltage by amplifying by a gain a first voltage that corresponds to the reference voltage. The main control unit is configured to calculate a valid gain corresponding to a ratio of the second voltage to the reference voltage when the temperature of the voltage detection unit is within a threshold temperature range.

    摘要： A Battery Management System (BMS) includes a sensing unit and a Micro Control Unit (MCU). The sensing unit measures a battery current, a battery voltage, and a battery temperature. The MCU determines a State of Charge (SOC) reset point based on the measured battery current and voltage. The BMS determines a battery overcharge state using a current integration result after the SOC reset point is reached. The MCU includes an SOC calculator and a full charge determining unit. The SOC calculator transmits a present current integration value upon detecting the SOC reset point. The full charge determining unit receives the present current integration value, integrates the current using the measured battery current, and determines that the battery is being overcharged when the current integration value reaches a predetermined battery rating

    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.
