Abstract

The invention discloses a distributed feed source switch reluctance motor system for flexible charging of an electromobile. The system comprises a switch reluctance motor and two transducers T1 and T2, wherein the switch reluctance motor is provided with four phase stator windings L1, L2, L3 and L4; the middle part of each phase stator winding is tapped; the transducer T1 is used for exciting the stator winding L1 and the stator winding L2; the transducer T2 is used for exciting the stator winding L3 and the stator winding L4; the topology of the switch reluctance motor has the five working modes of a battery voltage-sharing mode, a direct current charging mode, an interaction charging mode, a direct current cascade charging mode and an alternating current charging mode. The system input of the switched reluctance motor can be a direct current power supply or an alternate current power supply; the system can normally operate under the different battery SOC conditions, can be applied to a plurality of occasions, and is wider in input and output voltage range and wider in input and output power range.

Description

technical field [0001] The invention belongs to the technical field of motors, and in particular relates to a distributed source-fed switched reluctance motor system for flexible charging of electric vehicles. Background technique [0002] The shortage of fossil energy and the emission of greenhouse gases are two increasingly serious problems facing the world today. As a major oil consumer and waste emitter in the world, the automobile industry has brought many energy and environmental problems. According to statistics from the International Energy Agency, transportation oil will account for more than 62% of the world's total oil consumption by 2020, and vehicle exhaust emissions will account for more than 64% of air pollution sources. The development of new energy vehicles has gradually become the trend of the current automotive industry. Electric vehicles run on electric energy, which has the advantages of energy saving, environmental protection, and cleanliness. It can ...
