    摘要： A process for controlling temperature of a battery pack includes operating a fan to change a battery temperature to an optimal range of temperature (Topt) when a condition is satisfied that the battery temperature is equal to or greater than a maximum acceptable temperature (Tmax) or when the battery temperature is equal to or less than a minimum acceptable temperature (Tmin) and, at the same time, when the difference between a battery temperature (Tbat) and an air temperature (Tair) of air is equal to or greater than a critical temperature (Tct), and operating the fan to change the battery temperature to an optimal range of temperature variation (Topt1) of each unit cell when the battery temperature does not satisfy the condition, and a temperature variation (Tvar) of each unit cell is equal to or greater than a predetermined critical temperature (Tcrt1). According to the present invention, the operation of the fan is minimized, and therefore, optimal battery operation is accomplished while unnecessary power consumption is reduced. Furthermore, the temperature deviation between the unit cells is reduced, and therefore, the operation of the overall battery system is optimized.

    摘要： Disclosed herein is a secondary battery module constructed approximately in a rectangular parallelepiped structure. The battery module includes a pair of side members (right and left side members) having pluralities of grooves formed at the inside surfaces thereof such that the sides of unit cells are securely fitted in the grooves and at least one connection member integrally formed with the side members such that the side members are spaced apart from each other by the width of the unit cells while the grooves of the side members face each other. A medium- or large-sized battery system is manufactured using one or more secondary battery module. The secondary battery module allows a plurality of unit cells to be mounted in the battery module with high density. Consequently, the total size of the battery system can be considerably reduced, and the electrical connection between the electrodes is highly stable. Furthermore, a risk of an engineer or a user being exposed to the electrical short-circuits is minimized, and a risk of electrical short-circuits due to external forces is greatly reduced.
