Abstract: 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.

Abstract: 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.

Abstract: A system for managing the temperature of a battery, may include a battery configured to store electrical energy; a temperature-increase heater configured to convert the electrical energy stored in the battery into thermal energy to increase the temperature of the battery; a temperature-increase heater relay configured to connect or disconnect an electrical energy path provided from the battery to the temperature-increase heater; a thermal fuse configured to disconnect the electrical energy path when the temperature of the battery is equal to or higher than a predetermined reference temperature; and a controller configured to induce disconnection of the thermal fuse by increasing the temperature of the battery to the reference temperature or higher using the thermal energy converted by the temperature-increase heater, when the temperature-increase heater relay is fused.

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.

Abstract: An apparatus for controlling supply of power of a battery is provided. In particular the apparatus supplies battery power to various loads within a vehicle by a release of a door-lock using a key. The battery power is supplied to the loads by rotation of the key for releasing the door-lock when the power of the battery supplied to the various loads is blocked to prevent over-discharge.

Abstract: A method for reconnecting a relay in a vehicle battery management system includes: measuring an insulation resistance between a positive electrode or a negative electrode of a battery and a vehicle chassis; turning off each of relays connected between the positive and negative electrodes of the battery and a load when the measured insulation resistance is less than a reference value; re-measuring the insulation resistance; and performing a relay-on sequence for turning on each of the relays when the resistance value of the re-measured insulation resistance is greater than the reference value. A relay reconnection number of the relay-on sequence, based on a repetition of the measuring and re-measuring, is set and limited so as to not exceed a threshold value.

Abstract: A method and system for controlling the start of a vehicle are provided. The method includes determining whether a high voltage battery of a vehicle is submerged and outputting a warning regarding the submersion when the high voltage battery is submerged. In addition, power is cut off and the vehicle ignition or the start of the vehicle is turned off after the warning signal is output.
