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 to set an OCV setting of a battery, and a driving method thereof. The battery management system includes a sensing unit and a main control unit (MCU). The sensing unit measures a voltage of a battery. The MCU controls charging/discharging of the voltage of the battery, generates charge/discharge pulse pattern waveforms, measures and stores maximum and minimum voltages value of at least one pulse pattern among the charge/discharge pulse pattern waveforms, and sets an average of the measured voltage to an OCV setting from which an SOC is determined. The battery management system estimates the SOC while a vehicle is operating.

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.
