TRAY OF CELL PACK FOR HYBRID ELECTRIC AUTOMOBILES, IMPROVING LIFE SPAN OF CELL PACK

摘要

PURPOSE: Provided is a tray of cell pack for hybrid electric automobiles, in which multiple cooling fans are formed at one side of the tray to detect temperature of cells at each point and drive the cooling fan independently so that it reduces the temperature difference between the points of the cells. CONSTITUTION: The tray of cell pack for hybrid electric automobiles comprises the parts of: a tray body which are formed by module layers at a stacked structure, in which a module is formed by connecting multiple cells in serial and a module layer is formed by arranging multiple modules at the same plane; the cooling fan(3) which helps air flow to be separated at each layer, in which air flow is formed from lower side of one module to upper side of the other module; an air entrance(11) which is placed at lower opposite side of the cooling fan; and a thermistor which controls the cooling fan.
