  • Publication number: 20240336170
    Abstract: A walk-in apparatus for a vehicle seat includes a walk-in bracket rotatably coupled to a crossbar of a cushion frame and operable to release a fixing member by contacting the fixing member of a seat rail; a compensator bracket operably connected to the walk-in bracket through a hinge, the compensator bracket also being connected to a walk-in cable; and a compensator spring configured to support the walk-in bracket and the compensator bracket, rotate at least one of the walk-in bracket and the compensator bracket, and operate in such a manner as to return the compensator bracket. Even when the walk-in cable is released due to a seatback rebound phenomenon during a walk-in operation, the walk-in bracket maintains a pressing state of the fixing member to maintain continuously an unlocking state of the seat rail, allowing the vehicle seat to move forward smoothly to enable a walk-in operation.

  • Publication number: 20240339858
    Abstract: In a system for setting current capacity of a charging cable for supply of battery power from one electric vehicle to another electric vehicle, a discharge controller is provided in a supply vehicle to discharge a battery of the supply vehicle to supply battery power to a target vehicle. A charge controller is provided in the target vehicle to charge a battery of the target vehicle with battery power supplied from the supply vehicle. A charging cable part electrically connects the supply vehicle and the target vehicle. The discharge controller is configured to perform control so that a discharging current of the charging cable part is set by detecting an allowable charging current of the charging cable part connected to the supply vehicle and comparing the allowable charging current with a predetermined maximum current outputtable from the supply vehicle.

  • Patent number: 7674557
    Abstract: An electrode active material further comprising an amphoteric compound, an alkali metal sulfide or an alkali metal oxide, and lithium secondary batteries using the electrode active material, are disclosed. The lithium secondary batteries neutralize acids generating around electrode active material so that it can inhibit the reduction in battery capacity. In addition, the lithium secondary batteries are excellent in its charge-discharge characteristics, cycle life and thermal stability. A method for preparing the electrode active material for lithium secondary batteries is also provided.
