Abstract: In a driving system, first and second inverters are connected to a driving motor, one end of a stator winding through which 3-phase current flows is connected to an output line of the first inverter, and the other end of the stator winding is connected to an output line of the second inverter. A winding pattern of the driving motor includes: coils wound in slots defined in the stator and to which 3-phase current is applied; coils wound on innermost and outermost sides based on a direction toward a rotating shaft of the driving motor in the slots, and being energized by different AC phases; and coils disposed between a first coil located on the outermost side and a second coil located on the innermost side, and being energized by the same AC phases as those of the first and second coils.

Abstract: This application relates to an energy storage device. In one embodiment, the energy storage device includes an electrode unit including first and second current collectors that are separated by a separator, first and second terminals respectively connected to the first and second current collectors and a case accommodating the electrode unit. The energy storage device also includes a flexible closure covering the case and having first and second through-holes passing therethrough and exposing the first and second terminals to the environment, wherein the flexible closure contains about 15 wt % or less of SiO2. According to some embodiments, since the weight percentage of SiO2 is significantly reduced and thus, the amount and degree of the SiO2 reduction significantly decreases, a structural deformation of the flexible closure at a microscopic level is minimized. Accordingly, a wetting phenomenon is significantly reduced, and thus the life span of an energy storage device significantly increases.
