  • Publication number: 20140121873
    Abstract: Disclosed is a control method that improves response delay by reducing the time taken to determine the engagement type of an engine clutch, by making it possible to determine quickly the engagement type by a slip process under a disadvantageous operating conditions for the synchronization process such as traveling up a slope, traveling in a congestion section, or traveling under to or close to a discharging limit, and can improve fuel efficiency and battery SOC management due to unnecessarily using electric energy when engagement cannot be achieved by the synchronization process.

  • Publication number: 20060220611
    Abstract: Disclosed is a battery pack mounting apparatus for a portable terminal. The battery pack mounting apparatus includes a mounting recess and a battery pack. The mounting recess is formed on one surface of a terminal housing and extends through from one side of the terminal housing to the other side of the terminal housing. The battery pack is mounted in the mounting recess by sliding along a longitudinal direction that the mounting recess extends. Since a battery pack can be replaced while maintaining the power of a portable terminal in the ON state, the power can be stably provided to the portable terminal in spite of depletion of a battery during a long-duration operation. In addition, when a user has at least two battery packs, the portable terminal can be maintained in the ON state for a long period of time, regardless of battery capacity.
