1. A battery management system for a vehicle, comprising:
- a sensing unit configured to measure a current and a voltage of a battery for a vehicle;
a relay connected between the battery for the vehicle and electronic units of the vehicle; and
a controller configured to receive data from the sensing unit to turn off the relay wherein 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 greater, the controller for the vehicle is configured to maintain a standby mode during a sleep time period and measure voltage and current.

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.

9. 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 and in response to determining based on the measured voltage and current that a measured state of the battery is the predefined sleep reference value or greater, the controller for the vehicle is configured to maintain a standby mode during a sleep time period and measure voltage and current. - View Dependent Claims (10, 11, 12, 13)
