  • Publication number: 20220381835
    Abstract: When a use range of an SOC (State Of Charge) of a secondary battery is expanded, the use range of the SOC is expanded by increasing an upper limit value or decreasing a lower limit value of the use range of the SOC. The increasing the upper limit value or decreasing the lower limit value of the use range of the SOC is determined to a side causing a smaller increase in a degradation rate of the secondary battery, based on at least one of a cycle degradation characteristic that defines a cycle degradation rate in accordance with the use range of the SOC and a current rate of the secondary battery and a storage degradation characteristic that defines a storage degradation rate in accordance with the SOC and a temperature of the secondary battery, and a typical use condition of the secondary battery based on a use history of the secondary battery.

  • Publication number: 20220270651
    Abstract: A hard disk drive (HDD) includes an enclosure base, a first cover coupled to the base, and two separate gasket seals composed of different materials and configured to seal the interface between the first cover and the base. One gasket seal is composed of a material having a low permeability to helium or another lighter-than-air gas contained within the HDD, and the other gasket seal is composed of material having a low water vapor or moisture transmission. By using two separate independent gaskets which have different attributes, the lighter-than-air gas concentration is kept high and humidity is kept low during manufacturing testing, prior to affixing a hermetic second cover over the first cover, and degradation of HDD performance due to change of flying height is ultimately avoided.
