摘要： Disclosed herein is a secondary battery module comprising a plurality of unit cells stacked one on another, wherein the unit cells are spaced apart from each other such that a channel for heat dissipation is defined between the unit cells, the battery module further comprises at least one piezoelectric sensor mounted in the channel, and the at least one piezoelectric sensor is connected to a battery management system (BMS). According to the present invention, the piezoelectric sensor is mounted in the channel defined between the unit cells of the secondary battery module. Consequently, no additional space for installing the piezoelectric sensor is needed, and therefore, the increase of the size of the battery module is effectively prevented. Furthermore, the change of the internal pressure of the battery is accurately detected by the piezoelectric sensor, and therefore, the expansion or the explosion of the battery caused due to the overcharge or overheating of the unit cells is effectively prevented.

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 (Tmaχ) or when the battery temperature is equal to or less than a minimum acceptable temperature (Tmjn) and, at the same time, when the difference between a battery temperature (Tbat) and an air temperature (Tajr) of air is equal to or greater than a critical temperature (Tcrt), and operating the fan to change the battery temperature to an optimal range of temperature variation (Topti) 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 (Tcrtl). 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.
