  • Publication number: 20200371145
    Abstract: An abnormality determination device for a secondary battery includes an internal-resistance calculation unit, a threshold memory unit, a capacity balance comparison unit, and an abnormality determination unit. The internal-resistance calculation unit detects an internal resistance in a negative-electrode reaction resistance dominant region in which a reaction resistance of a negative electrode is dominant in a charge and discharge reaction of the secondary battery. The threshold memory unit stores a capacity balance threshold used as a reference for determining abnormality in a balance between a capacity of a positive electrode and a capacity of the negative electrode in the secondary battery. The capacity balance comparison unit compares the internal resistance calculated by the internal-resistance calculation unit with the capacity balance threshold stored in the threshold memory unit.

  • Patent number: 10720492
    Abstract: The width of the p type guard ring is set to match the interval between the adjacent p type guard rings, and the width of the p type guard ring is made larger as the interval between the p type guard rings becomes larger. The width of the frame portion is basically equal to the width of the p type deep layer so that the interval between the frame portions is equal to the interval between the p type deep layers. This makes it possible to reduce the difference in formation areas of the trenches per unit area in the cell portion, the connection portion and the guard ring portion. Therefore, when the p type layer is formed, the difference in the amount of the p type layer embedding into the trenches per unit area also decreases and the thickness of the p type layer is equalized.
