  • Patent number: 11656282
    Abstract: Based on a voltage of a secondary battery detected by a voltage measurement unit, a residual capacity is acquired from a correlation between the voltage and the residual capacity of the secondary battery stored in a memory, and a state of charge (SOC) which is a ratio of the residual capacity to a reference capacity is obtained. The reference capacity is set to a prescribed amount less than a residual capacity at full charge. Further, an information processing unit determines an abnormality of a module based on a comparison between the SOC and an SOC obtained by another method.

  • Patent number: 9865881
    Abstract: Provided is an electrode assembly including: a negative electrode including a negative electrode current collector (NC) and a negative electrode active material layer (NAL) disposed on at least one surface of the NC; a positive electrode including a positive electrode current collector (PC), a positive electrode active material layer (PAL) disposed on at least one surface of the PC, and an undercoat layer being disposed between the PC and the PAL and being higher in resistance value than the PC. The negative electrode and the positive electrode are stacked on each other. In at least one side of the thus stacked negative and positive electrodes, the NAL projects from an edge of the PAL in a direction in which the NC and PC extend, and the undercoat layer projects from an edge of the NAL in the direction.
