Abstract

The invention discloses a switched reluctance motor transmission system of a plug-in hybrid electric vehicle. The switched reluctance motor transmission system comprises a switched reluctance electric generator, a switched reluctance motor, a front-end converter, a traction storage battery and an auxiliary storage battery; and the switched reluctance electric generator is connected with an internal combustion engine and driven by the internal combustion engine to generate electricity; and the switched reluctance electric generator comprises a three-phase stator winding and a power converter of the three-phase stator winding, and the switched reluctance motor comprises a three-phase stator winding and a power converter of the three-phase stator winding. By controlling turn-on and turn-off of five relays, switching of different working modes of the plug-in hybrid electric vehicle is achieved. According to the switched reluctance motor transmission system, the switched reluctance motor driving system without rare earth materials is designed, the switched reluctance motor transmission system is applied to an electric vehicle electric driving system, and by utilizing the motor windings and an existing power converter, the different driving modes and the flexible charging function are achieved without external-connection elements.

Description

technical field [0001] The invention belongs to the field of plug-in hybrid electric vehicles, and in particular relates to a transmission system of a plug-in hybrid electric vehicle. Background technique [0002] Compared with hybrid electric vehicles, plug-in hybrid electric vehicles have a larger battery capacity and can also be connected to the grid for charging. Compared with pure electric vehicles, plug-in hybrid electric vehicles have internal combustion engines and have longer cycle mileage, which can eliminate range anxiety. Plug-in hybrid electric vehicles are a better choice at the current level of battery technology. The electric drive system and the on-board battery charging system are two important components of the plug-in hybrid electric vehicle. At present, most commercial electric vehicles use permanent magnet synchronous motors, but permanent magnet motors require rare earth materials, and the high price of rare earth materials limits the wide applicatio...
