Starting power generation conversion control method for range extender of electrical vehicle

电动汽车增程器起动发电转换控制方法

Abstract

本发明提供一种电动汽车增程器起动发电转换控制方法,属于电动汽车控制技术领域,主控电路协调控制起动电路和起动发电转换电路,使起动发电机工作,其特征在于:起动发电机的工作状态分为起动状态和发电状态,当蓄电池荷电状态低于30%时,起动发电机起动发动机运行,当发动机正常运行后,起动发电机转换为发电机运行,快速给蓄电池补充电能,增加电动汽车续驶里程。
The invention provides a starting power generation conversion control method for a range extender of an electrical vehicle, and belongs to the technical field of electrical vehicle control. The control method is characterized in that a starting power generator works by coordinated control of a main control circuit on a starting circuit and a starting power generation conversion circuit; the working state of the starting power generator includes a starting state and a power generation state; when the charge state of a storage battery is lower than 30%, the starting power generator enables an engine to run; after the engine runs normally, the starting power generator is converted into a power generator for supplying power to the storage battery and extending the driving range of the electrical vehicle.
