    Abstract: The disclosure relates to a battery management apparatus, a vehicle having the same, and a method of controlling the vehicle. A method of controlling the vehicle having a motor, an engine, and a battery includes detecting respective voltage values of the plurality of cells provided in the battery; identifying a maximum voltage value and a minimum voltage value among the voltage values of the plurality of cells; obtaining a voltage deviation value between the identified maximum voltage value and the minimum voltage value; obtaining a deterioration rate of the battery; obtaining a power limit value of the battery based on at least one of the voltage deviation value or the deterioration rate of the battery; obtaining a final power limit value based on the obtained power limit value and a preset weight; and controlling a discharge of the battery based on the obtained final power limit value.

    Abstract: A stable power supply device for a high voltage battery system in a vehicle enables the voltage of a capacitor in a high voltage component to be gradually increased at an initial stage of ignition, using a heat generating resistor of a temperature raising system mounted to raise the temperature of a battery in the vehicle. Further, the stable power supply device enables a capacitor in a high voltage component to be discharged using a heat generating resistor of a temperature raising system after the ignition of the vehicle is off, thereby ensuring the stability of the system.

    Abstract: A battery management system for a vehicle is provided to prevent an additional discharge of a first battery and improve marketability of the vehicle by controlling an ignition of the vehicle during an over-discharge of the first battery. The battery management system includes a sensing unit that is configured to measure currents and voltages of first and second batteries. A first relay is connected between the first battery and electronic units of the vehicle and a second relay is connected between the second battery and the controller. Additionally, the controller is configured to receive data from the sensing unit to turn off the first relay or turn on the second relay.
