Abstract: A battery cooling device for a vehicle is provided. The device repeats phase changes of a refrigerant to cool a battery due to heat of vaporization when a liquid-state refrigerant is vaporized by thermally coming in contact with a battery heat source. The vaporized refrigerant is changed back into a liquid state by thermally coming in contact with a separate coolant. The effect of cooling all battery cells is maximized throughout the entire refrigerant channel for cooling a battery and the battery cells are cooled uniformly.

Abstract: A system and a controlling method for extinguishing a fire in a battery of a vehicle is provided for preventing the vehicle from being completely burned out and protecting consumer's physical assets by injecting cooling water of a water cooling system when a fire occurs in a battery to extinguish the fire of the battery at an early stage and by supplying an external cooling material from outside of the vehicle to extinguish the fire of the battery when the fire of the battery is not extinguished at the early stage.

Abstract: A cooling device, which cools a battery by effectively dissipating heat generated from the battery, which is used, for example, in eco-friendly vehicles, is provided to increase the rate of battery charging and the reliability of the battery. The cooling device includes a pair of coolant pipes that introduce and discharge a coolant and a cooling channel that connects the coolant pipes to each other to move the coolant from a first coolant pipe to a second coolant pipe.

Abstract: A battery temperature raising system and a control method thereof are provided. The battery temperature raising system includes a power supply that operates a heater attached to a battery module. The heater is configured to increase a battery temperature and a variable resistor mounted on a circuit between the heater and the power supply adjusts a heating value of the heater based on an adjustment state of a resistance value. A heater relay is mounted on the circuit between the heater and the power supply and opens and closes the circuit to selectively turn on/off the heater. A first sensor senses the battery temperature and a second sensor senses a heater temperature. A controller outputs a control signal to operate the heater relay to selectively turn on/off the heater based on temperature information sensed by the sensors and a control signal to adjust the resistance value of the variable resistor.

Abstract: A water-cooled battery module of an electric vehicle is provided. According to the water-cooled battery module, cooling efficiency between a heat exchange pad and battery cells is enhanced since the heat exchange pad through which a cooling medium flows is made of a material having high heat transfer efficiency. Further, since heat dissipation plates with which the battery cells contact are in uniform surface contact with the heat exchange pad, cooling efficiency is enhanced by virtue of the uniform contact.

Abstract: A battery overcharge safety system of a passive control method is provided which uses a Zener diode and a neutral material to prevent a battery mounted in an eco-friendly vehicle from being overcharged. More particularly, the battery overcharge safety system prevents a battery mounted in an eco-friendly vehicle from being overcharged using a Zener diode which generates heat when the battery is overcharged and a neutral material which is vaporized and expands by the heat generated in the Zener diode to operate an overcharge preventing switch.
