Description

Battery System The present disclosure relates to a battery system. Unlike primary batteries, secondary batteries can be charged and discharged, so they can be applied in various fields such as digital cameras, mobile phones, laptops, hybrid cars, and electric vehicles. Examples of secondary batteries include nickel-cadmium batteries, nickel-metal hydride batteries, nickel-hydrogen batteries, and lithium secondary batteries. Multiple such secondary batteries are stacked to form a cell stack. Then, multiple cells constitute a battery module, and multiple modules again constitute a battery system. If the temperature of a secondary battery rises above the optimal level, its performance may deteriorate, and in severe cases, there is a risk of explosion or ignition. A vent structure is applied to minimize damage in the event of thermal runaway. In addition, lightweight design is essential to increase the energy efficiency of battery devices, such as battery modules and battery systems. FIG. 1 is an exploded perspective view of a battery system according to one embodiment of the present disclosure. Figure 2 is a front view of the combined state of the battery system of Figure 1. FIG. 3 is a perspective view showing a state in which battery cells are stacked and accommodated in the housing and reinforcing member of FIG. 1. FIG. 4 is a perspective view showing a state in which a battery module is accommodated in the housing and reinforcing member of FIG. 1. FIG. 5 is a perspective view showing a state in which a porous member is placed in the vent of the housing of FIG. 1. FIG. 6 is a perspective view showing the combined state of the housing and reinforcing member of FIG. 1. Figure 7 is a cross-sectional view of the combined state of the battery system of Figure 1. Hereinafter, the present disclosure will be described in detail with reference to the attached drawings. However, this is merely illustrative and the present disclosure is not limited to the specific embodiments described illustratively. The following embodiments are provided to more faithfully and completely explain the technical concept of the present disclosure to those skilled in the art to which the present disclosure pertains. Accordingly, the technical concept of the present disclosure is not necessarily limited to the following embodiments.
