The present invention relates to a method for charging battery of a hybrid vehicle at neutral shift range and a hybrid vehicle using the same which enable generating and charging battery at a neutral shift range by restricting a rotation of an output element of the automatic transmission. A preferred method for charging battery of a hybrid vehicle at a neutral shift range according to an exemplary embodiment of the present invention includes determining whether current shift range is neutral shift range; measuring a battery SOC(state of charge); operating an EHB (Electro Hydraulic Brake) when the measured battery SOC is lower than a predetermined lower limit battery SOC; operating an generator by operating an engine; measuring a battery SOC after operating the generator; releasing EHB when the battery SOC measured after operating the generator is higher than the predetermined lower limit battery SOC.

A parking brake apparatus for an automatic transmission vehicle in one embodiment includes a parking shaft connected to a shift lever, a cam plate secured to the parking shaft, a parking rod assembly operated when the cam plate secured to the parking shaft rotates through manipulation of the shift lever, and a parking gear meshed with a sprag which is actuated by the parking rod assembly. The apparatus comprises a driving section having a driving motor assembly for driving the parking shaft such that the sprag can be engaged with or disengaged from the parking gear when the shift lever is manipulated between P and R, and operating to ensure that a rotational force of a driving motor is added to a disengaging force of the parking rod assembly for disengaging the sprag engaged with the parking gear when the disengaging force is insufficient.
