  • Publication number: 20120299597
    Abstract: In a battery system of the invention, a BMS calculates a maximum charge rate representing a maximum value from present charge rates of plurality of secondary batteries constituting an assembled battery and a minimum charge rate. Then, the BMS generates a normal waveform signal in which the maximum charge rate is determined as a maximum peak and the minimum charge rate is determined as a minimum peak as a waveform signal which is displayed in a charge rate display range where a full charge rate in the case of a full charge state of the secondary battery is determined as an upper limit and an empty charge rate in the case of an empty charge state of the secondary battery is determined as a lower limit. Then, the BMS displays the normal waveform signal in the charge rate display range.

  • Patent number: 8200444
    Abstract: A system includes an implantable battery, an implantable medical device powered by the battery, a first resistance, a second resistance, a first memory register and a second memory register. The implantable medical device has first and second current drain states. The first resistance is connected to the battery through a first current path when the device is in the first current drain state, wherein current is prevented from flowing through the first current path when the device is in the second current drain state. The second resistance is connected to the battery through a second current path when the device is in the second current drain state, wherein current is prevented from flowing through the second current path when the device is in the first current drain state. The first memory register is configured to store a cumulative first current drain state count indicative of total charge drawn from the battery when the device is in the first current drain state.

  • Publication number: 20120112754
    Abstract: A rechargeable battery state-of-charge quantifying apparatus for use in a vehicle equipped with an electric motor and a rechargeable battery which supplies electric power to the motor to produce a driving torque. The apparatus quantifies a state-of-charge of the rechargeable battery and defines a minimum value of a state-of-charge of the rechargeable battery at which the rechargeable battery is permitted to produce a degree of electric power required to run the vehicle as a lower limit. The lower limit is increased as the rechargeable battery ages, thereby ensuring the stability in supplying the amount of electric power to the motor which is required to run the vehicle regardless of aging of the battery.
