Latest Patents

One of Takumi Oya's latest patents is an assembled battery. In this assembled battery, connections between electrode terminals of electrical cells and connection members for the electrode terminal are reliably maintained for a long period of time. The electrode terminal is formed in a tapered pillar shape whose width decreases from the front end of the electrode terminal toward a battery case. Additionally, a groove, which is shaped from the front end toward the battery case and divides at least a portion of the front end into segmented portions, is provided to the electrode terminal. The segmented portions are elastically deformable to move close to or away from each other. The bus bar, which serves as a connection member for the electrode terminals, includes a through-hole whose width decreases from the front end of the electrode terminal toward a battery case. The bus bar is fitted to the electrical terminal by elastically deforming and moving the segmented portions close to each other.

Another significant patent is a battery system that comprises a first battery cell and a first management unit, which is connected in one-to-one correspondence to the first battery cell. The first management unit consists of a first parameter acquiring unit, a first calculating unit, and a first storage unit. The first parameter acquiring unit acquires a power consumption parameter of the first battery cell. The first calculating unit calculates a power consumption state value of the first battery cell based on the power consumption parameter acquired by the first parameter acquiring unit. The first storage unit stores the power consumption state value calculated by the first calculating unit.
