Fuel generation type range-extended electric vehicle controller

Abstract

The invention discloses a fuel generation type range-extended electric vehicle controller, which comprises a voltage comparison circuit, a mode conversion switching circuit, a vehicle speed-sensing circuit, an engine speed-sensing circuit, a miss control circuit, a rotational speed display circuit, an accelerator control circuit, a voltage-regulating circuit, a generator phase sequence signal pickup circuit, a phase A MOS (metal oxide semiconductor) transistor drive circuit, a phase B MOS transistor drive circuit, a phase C MOS transistor drive circuit and a current-limiting protection circuit, a master control chip is connected with the voltage comparison circuit, the mode conversion switching circuit, the vehicle speed-sensing circuit, the engine speed-sensing circuit, the miss control circuit, the rotational speed display circuit and the accelerator control circuit, a slave control chip is connected with the voltage-regulating circuit, the generator phase sequence signal pickup circuit, the phase A MOS transistor drive circuit, the phase B MOS transistor drive circuit, the phase C MOS transistor drive circuit and the current-limiting protection circuit, and the master control chip is connected with the slave control chip. By means of an intelligent control measure, the controller can automatically start a fuel generator to operate to charge a storage battery when the voltage of the storage battery is low, and after an electric vehicle starts to run, an engine automatically increases the speed. When the storage battery is fully charged, the fuel generator is automatically shut down. Consequently, the controller not only effectively prevents inconvenience and loss brought to a user as the result of the stopping of the electric vehicle on the midway caused by the shortage of the electricity of the storage battery, but also solves the technical problem that the service life of the storage battery is short due to the insufficient voltage of the storage battery, and meanwhile, the controller can meet the requirement of endurance.

Description

technical field

[0001] The invention relates to a controller for an electric vehicle, in particular to a controller for an extended-range electric vehicle powered by fuel oil to increase the cruising range. 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 power to the drive motor, and then drive the wheels to run, so as to achieve the purpose of driving in pure electric mode. The advantages of this stru...
