Power system simulation device and simulation method for high-speed electric vehicle

Abstract

The invention discloses a power system simulation device and a simulation method for high-speed electric vehicle. The traditional fossil-fueled vehicles severely pollute the environment, and have thepotential to develop towards the direction of low noise and zero emission electric vehicle. The composition of the invention comprises a series type double-motor (5); the series type double-motor adopts two permanent magnet synchronous motors connected in series and connected to a left motor controller (7) and a right motor controller (4) through wires respectively; the left motor controller and the right motor controller are connected to a data acquisition and control system (3) through wires respectively; the data acquisition and control system is connected to a CAN bus interface module (2)through a CAN bus; the CAN bus interface module is connected to the industrial control computer (1) through a USB interface; the right end of the series type double-motor is connected to a torque sensor (8) through a coupling A (6); the torque sensor is connected to a gearbox (14) through a coupling B (9); and the gearbox is connected to the transaxle (15) through a connecting shaft. The inventionis used for high-speed electric vehicle power system simulation device.

Description

Technical field: [0001] The invention relates to a high-speed electric vehicle power system simulation device and simulation method.
