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 method for controlling an output of a battery includes measuring a state of charge (SOC) or a resistance of the battery of a vehicle, comparing a deterioration level of the battery with a set deterioration level, and controlling a temperature of the battery, an average output of the battery, and a load mode of the battery when the deterioration level of the battery is larger than the set deterioration level.

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 high voltage battery includes an electrode assembly. A pouch-shaped case is sealed by an edge portion to cover the electrode assembly and has an open inlet formed at one side of the case to allow an electrolyte to be injected to the case therethrough. An outlet is connected to the inlet and discharges gas generated inside the case outside a vehicle.

Abstract: The present invention provides a high voltage system of an electric vehicle. More particularly, it relates to a high voltage system of an electric system which makes it possible to remove a sub-battery conventionally required in such systems by allowing a high voltage battery to function as the sub-battery. The high voltage system includes a high voltage battery, in which a cell and/or a module of the high voltage battery is connected to low voltage electric equipment through an NC relay, such that power of the cell and/or the module of the high voltage battery is supplied to the low voltage electric equipment at ignition-off.

Abstract: A method of preventing condensation of a battery pack in an eco-friendly vehicle including measuring a temperature of the battery pack provided in the eco-friendly vehicle and a temperature of air introduced into the battery pack through an air-cooled device for maintaining the battery pack at a set temperature. A humidity of air introduced into the battery pack is measured. Whether condensation is generated is determined based on the temperature of the battery pack, the air temperature, and the air humidity; and the temperature of the battery pack is increased.

Abstract: Provided is an technique for protecting a battery pack, in which an insulating film member and a support member are installed in a housing surrounding the battery pack, and the insulating film member is wound around and unwound from the support member fixedly installed in the housing. The technique prevents a short circuit from being caused by a conductive object penetrating into a high-capacity battery used in an HEV, PHEV or EV, so that it can prevent ignition and smoke from being generated by the battery as a result. The technique is configured to mount a battery of an HEV, PHEV or EV within a spatial margin and increase safety in the event of a collision. The technique can be applied to all vehicles using electricity in addition to the HEV, PHEV or EV.
