Abstract
A battery management system for a vehicle is provided to prevent current consumption of a battery by operating a relay connected between the battery and electronic loads to prevent an over-discharge of the battery. The battery management system includes a sensing unit that is configured to measure a current and a voltage of a battery for a vehicle and a relay that is connected between the battery for the vehicle and electronic units of the vehicle. Additionally, a controller is configured to receive data from the sensing unit to turn off the relay.

12. A controlling method of a battery management system for a vehicle, comprising:
-
measuring, by a controller, a voltage and a current of a battery for a vehicle in response to driving of an engine being terminated; and in response to determining based on the measured voltage and current that a measured state of the battery is a predefined sleep reference value or less, turning off, by the controller, a relay connected between the battery for the vehicle and electronic units of the vehicle. - View Dependent Claims (13, 14, 15, 16)
