Abstract: An embodiment vehicle includes a DC/DC converter having a first power terminal connected to a first electrode of a first battery, a second power terminal connected to a first electrode of a second battery, and a load terminal connected to a first end of an electric load, and including a switching circuit, a transformer, and a rectifier circuit, and a controller configured to set an operation mode of the DC/DC converter to a low-voltage DC/DC converter (LDC) mode or a state-of-charge (SOC) balancing mode, wherein the DC/DC converter is configured to step down a voltage of the first power terminal through the switching circuit, the transformer, and the rectifier circuit and output the voltage to the load terminal when the LDC mode is performed and to control power transfer between the first and second power terminals through the switching circuit when the SOC balancing mode is performed.

Abstract: The present invention relates to a method for preparing an alkali metal ion conductive chalcogenide-based solid electrolyte, a solid electrolyte prepared thereby, and an all-solid-state battery comprising the same.

Abstract: A transmission for a hybrid vehicle may include an input shaft into which power generated by an engine is input, an output shaft disposed coaxially with the input shaft, a first planetary gear set, a second planetary gear set, and a third planetary gear set disposed between the input shaft and the output shaft to transmit rotational force, each of the first to third planetary gear sets having first, second and third rotary elements, a first motor generator and a second motor generator each connected to the first to third rotary elements of the first to third planetary gear sets, and at least three shifting elements each connected to the first to third rotary elements of the first to third planetary gear sets.

Abstract: A transmission structure of a hybrid electric vehicle (HEV) may include an engine connected to a front wheel of the hybrid vehicle, a planetary gear part connected to the engine, a first motor generator connected to the planetary gear part, an overdrive brake connected to the first motor generator, and a second motor generator connected to a rear wheel of the hybrid vehicle.

Abstract: A transmission for a hybrid vehicle includes a planetary gear set including at least three rotary members of which one is connected to an engine. A first anti-rotator selectively restricts rotation of the rotary member connected to the engine. A first motor generator is connected to another one of the rotary members of the planetary gear set. A second motor generator is connected to the remaining one of the rotary members of the planetary gear set. An output shaft has a first output gear thereon, which is externally engaged with the rotary member connected to the first motor generator. A second anti-rotator selectively restricts rotation of the rotary member connected to the second motor generator.
