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 an 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 and a driving method include a first switch coupled to an end of a resistor. When calculating an internal resistance of a battery, the first switch is turned on and the battery and the resistor are coupled in parallel. Then, the internal resistance of the battery is calculated by using a second current flowing to the battery and a first current flowing to the resistor.

摘要: A battery management system (BMS) includes at least one sub-BMS and a main BMS. The at least one sub-BMS measures information about a battery, and generates an activation signal according to operating state. The main BMS receives the activation signal and determines the operating state of the at least two sub-BMSs. If the at least two sub-BMSs normally operate, the main BMS generates a synchronization signal and transfers the same to the sub-BMSs. The at least one sub-BMS measures the information about the battery according to the synchronization signal.
