Electrically-driven vehicle

An electrically-driven vehicle includes a high-capacity battery unit and a high-output battery unit, both of which supply electric power to rotating electric machines, and a charging inlet serving as a charging port of an external power supply. The high-capacity battery unit receives more charge power from the charging inlet than the high-output battery unit and is positioned nearer to the charging inlet than the high-output battery unit is to the charging inlet. In this way, an electric power loss increase caused by a wiring resistance during an external charge can be suppressed in a plug-in type electrically-driven vehicle, which is chargeable by an external power supply.

Power split hybrid power system and hybrid vehicle

The present invention provides a power split hybrid power system and a hybrid vehicle. The hybrid power system comprises two planetary gear mechanisms sharing planetary carriers and ring gears, two motors and one engine. An output shaft of the engine is in transmission connection with a first sun gear shaft of a first sun gear, an input/output shaft of a first motor is in transmission connection with a second sun gear shaft of a second sun gear, and an input/output shaft of a second motor is in transmission connection with the ring gears. The output shaft of the engine, the input/output shaft of the first motor and the input/output shaft of the second motor can be relatively fixed to a housing of a transmission through a braking mechanism. Therefore, the power split hybrid power system can guarantee that a vehicle reaches a high speed in a pure motor driving mode so as to complete New European Driving Cycle and World Light Vehicle Test Cycle; and the engine can also be shut down at a high vehicle speed, and the dynamic property is improved in a low-speed state.
