    Abstract: State based full and empty control for rechargeable batteries that will assure a uniform battery empty condition, even in the presence of a load on the battery. A fuel gauge provides a prediction of the open circuit voltage of the battery, and when the predicted open circuit voltage of the battery reaches the predetermined open circuit voltage of an empty battery, the load is terminated, after which the battery will relax back to the predetermined open circuit voltage of an empty battery. A similar technique is disclosed for battery charging, allowing faster battery charging without overcharging. Preferably an RC battery model is used as the fuel gauge to provide the prediction, but as an alternative, a coulomb counter may be used to provide the prediction, with error correction between successive charge discharge cycles.

  • Patent number: 9651583
    Abstract: A measurement module includes a pair of input terminals, a pair of current paths connected to the pair of input terminals, and a pair of output terminals. A partition that is a non-magnetic insulating portion partitions an internal space of the measurement module into two spaces. Low-current components such as a magnetic detection element are disposed in a space different from a space in which the pair of current paths are housed. The presence of the partition allows the low-current components and the pair of current paths to be disposed close to one another, thus making it possible to reduce the size of the measurement module.

  • Patent number: 9551753
    Abstract: The state of a plurality of electric storage blocks connected in serial is determined. Each of the electric storage blocks includes a plurality of electric storage elements connected in parallel. Each of the electric storage elements includes a current breaker configured to break a current path in the electric storage element. When a first voltage characteristic is shifted from a second voltage characteristic, it is determined that the current breaker is operated. The first voltage characteristic is acquired from a voltage sensor acquiring an open circuit voltage of each electric storage block and indicates a change in the open circuit voltage with respect to a capacity of the electric storage block. The second voltage characteristic is calculated from a capacity retention rate and a variation of the capacity and indicates a change in the open circuit voltage with respect to the capacity of the electric storage block.
