Abstract: 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.

Abstract: A power transmitting system suitable for use with a hybrid vehicle is provided and preferably may comprise: (i) a first shaft and a second shaft; (ii) a planetary gear set; (iii) a power receiving apparatus that can receive power from the planetary gear set; (iv) a power transmitting member preferably in communication with the power receiving device and the second shaft to transmit power from the power receiving device to the second shaft. Because in preferred systems tension of a chain of a power transmitting system of a hybrid vehicle is not transmitted to a simple planetary gear set, damage to the simple planetary gear set may be prevented and the power transmitting system of the hybrid vehicle may be applied to many kinds of vehicles.

Abstract: A power delivery system of a hybrid vehicle realizes a speed reduction route and a speed increase route, and thereby enhances fuel economy.

Abstract: An exemplary automatic transmission of a hybrid vehicle according to an embodiment of the present invention includes a flywheel connected to an engine, a generator having a stator part and a rotor part, an input shaft connected with the rotor part, a hub coupled to an end of the input shaft, and a torsional damper connecting the flywheel with the hub, wherein the torsional damper includes a torsional spring and a plate, an end of the stator part is projected further toward the engine than an end of the rotor part and forms a projected portion, a vacant space is formed inside the projected portion, the plate is formed to be bent such that a mounting part mounted to the torsional spring is nearer to the generator than a mounting part mounted to the flywheel, and at least a part of the torsional spring is disposed in the vacant part.

Abstract: In a cooling apparatus, the amount of coolant flowing into an inlet and exhausted outlet is equalized, so cooling performance is not deteriorated.

Abstract: A powertrain of a hybrid vehicle includes: a first shaft to which an engine, a generator, and a motor are mounted, and to which a planetary gear set is also mounted between the generator and the motor; a second shaft to which are mounted a second shaft driven gear connected to the first shaft and a second shaft drive gear shaft-connected to the second shaft driven gear; a third shaft to which are mounted a third shaft driven gear connected to the second shaft and a third shaft drive gear shaft-connected to the third shaft driven gear; and a fourth shaft to which are mounted a differential ring gear connected to the third shaft and a differential apparatus.
