A system for managing a battery of a vehicle includes a first controller configured to control a power-on (IG ON) state and a power-off (IG OFF) state of a plurality of controllers in the vehicle and to be periodically woken up in the power-off (IG OFF) state to wake up at least some of the plurality of controllers, and a second controller configured to turn off a main relay connecting a first battery in the vehicle and a vehicle system when the power-off (IG OFF) state begins, to monitor a state of the first battery storing energy for generating power of the vehicle by maintaining power during a preset first reference time, to be woken up at a wake-up period of the first controller when the first reference time elapses, and to monitor the state of the first battery.

System and method for managing battery of vehicle

A braking control system for a vehicle is provided. The system includes a motor providing rotational force to wheels of the vehicle and a first battery storing electric energy for driving the motor. An inverter is connected to the first battery via a DC link terminal and performs a bidirectional power conversion between the DC link terminal and the motor. A DC converter is connected to the DC link terminal to down-convert a voltage of the DC link terminal and output the down-converted voltage. A second battery is supplied with the voltage converted by the DC converter and has a voltage lower than that of the first battery. A controller operates the inverter and the DC converter to charge regenerative braking energy generated from the motor during braking of the vehicle in the first battery and the second battery.

Braking control system and method for vehicle

A battery management system (BMS) may include a battery, a relay configured to electrically connect and disconnect the battery for supplying a voltage (an electric power) to an electric load to and from the electric load, the electric load configured to receive the voltage (the electric power) from the battery, to compare the received voltage (the electric power) with a reference value and to output a wakeup signal according to the compared result, when the relay is electrically connected, and a controller configured to wake up by the wakeup signal, to monitor a state of the battery and to control a state of the relay. It is possible to prevent overdischarge and overcharge of the battery by monitoring the battery through the electric load in a state in which a vehicle is turned off and switching the BSM to a wakeup state only if necessary.

Battery management system and method of controlling the same

A method and system for detecting fusion of a relay are provided to more accurately diagnose fusion of a relay by adjusting relay OFF order when a vehicle engine is turned off using data regarding whether fusion of a relay was detected when the vehicle engine was turned on. The method includes detecting whether first and second relays have been fused when a vehicle engine was turned on and adjusting OFF order of the first and second relays when the vehicle engine is turned off based on whether the first and second relays have been fused.

Method and system for detecting fusion of relay

A battery system for a vehicle includes: a battery assembly including at least one first battery module and at least one second battery module; a first relay being closed/opened between a first node and one of a first end of the first battery module and a first end of the second battery module being connected to a second end of the first battery module; a second relay being closed/opened between a second node and a second end of the second battery module; a converter converting a voltage between the nodes; a third relay being closed/opened between the converter and the first end of the first battery module; a fourth relay being closed/opened between the first end of the first battery module and a ground; and a battery manager controlling the relays based on a driving condition of the vehicle and energy storage amounts of the modules.

Battery system for vehicle

A battery management system for a vehicle is provided. The system is capable of preventing vehicle malfunction by preventing overcharge and over-discharge of a low-voltage battery by providing a controller that is configured to receive power transmitted from a first connection line and power transmitted from a second connection line. The battery management system includes a relay configured to electrically connect and disconnect power that is supplied from a battery to loads. The system also includes a controller configured to receive a first regular power transmitted through a connection line between the battery and the relay and a second regular power transmitted through a connection line between the relay and the loads. The controller is further configured to turn the relay on and off.
