Plug-in range-extended electric vehicle controller

Abstract

The invention relates to a plug-in EREV (Extended Range Electric Vehicle) controller. The plug-in EREV controller is formed by an engine start control module and a three-phase rectifying module, wherein the engine start control module is connected between a generator and a storage battery and is used for charging the storage battery after alternating current generated by the generator is rectified; the three-phase rectifying module is respectively connected with the generator and the storage battery; and a one-way electric conductor which is used for preventing the charging of the storage battery as electricity generating current of the generator flows through the engine start control module is arranged between the engine start control module and the storage battery. The plug-in EREV controller disclosed by the invention has an automatic mode, an all-electric-vehicle mode and an oil drive mode, not only is the problem that an electric vehicle stops running halfway due to the electricity shortage of the storage battery effectively solved, but also the technical difficulty that the service life of the storage battery is short due to the electricity loss of the storage battery is solved; and the plug-in EREV controller disclosed by the invention is particularly suitable for the full-automatic control of the starting, the rectifying and the charging of a large-power fuel oil engine of which the power is more than 2 KW.

Description

technical field [0001] The invention relates to an electric vehicle controller, in particular to a plug-in extended-range electric vehicle for increasing the cruising range by starting and rectifying a fuel generator combined with an engine and a generator to provide electric energy for the driving motor and battery of the electric vehicle controller. Background technique [0002] With the rapid development of the national economy and the implementation of the country's policy of enriching the people, the concepts of green environmental protection, energy saving and emission reduction and low-carbon consumption have become the mainstream of social development, and people's demand for electric vehicles is increasing day by day. Poor capacity and short driving distance have always restricted the healthy development of electric vehicles and brought great inconvenience to users. [0003] At present, electric vehicles in the industry generally use storage batteries to supply pow...
