Generator control system of range-extended electric car

Abstract

The invention discloses a generator control system of a range-extended electric car, which comprises an engine of which an ignition circuit is connected to a car controller, and is characterized in that a left crank shaft and a right crank shaft are connected to a left rotor and a right rotor of the engine respectively; the stator of the engine is connected with an output control module of the generator, which is further connected with the car controller; the car controller is connected with a mode-I key and a mode-II key; and the direct output end of the output control module of the generator is connected with an electric motor controller, and the output end of the electric motor controller is connected to the electric motor. The invention has the following beneficial effects: the generator is smaller in spatial dimensions, so as to facilitate the layout of a small electric car and reduce the manufacturing cost; the generator control system is favor of balancing the crank shafts of the engine, reduces the vibration of the engine and improves the overall comfort of the car; and the generator control system is suitable for requirements of various automobile models and makes effective and reasonable use of electric energy resources.

Description

technical field [0001] The invention belongs to an on-board generator of an electric car, and in particular relates to a range-extended electric new on-board generator for a car. Background technique [0002] There are various drawbacks in the currently commonly used fuel engine vehicles. Statistics show that under the road conditions that account for more than 80%, an ordinary car only uses 40% of its power potential, and it will drop to 25% in urban areas. More serious Is the emission of waste gas to pollute the environment. Since the 1990s, the voices of various countries in the world for improving environmental protection have become increasingly loud, and various electric vehicles have come to the fore. [0003] Because the energy density of batteries is a hundred times worse than that of gasoline, which is far from the required value, experts estimate that electric vehicles will not be able to replace gasoline engine vehicles within 10 years. The reality forced engine...

Problems solved by technology

[0008] The disadvantage of the prior art is that the structure of the existing electric vehicle is complex due to the three parts of the power entity including the engine, the generator and the motor, and the battery occupies a large amount of space, so the spatial arrangement of the entire power system is a difficult problem to solve , At the same time, there is another key component of electric vehicles - the on-board battery, which supplies power to the motor. However, after long-term use, the voltage of the on-board battery changes greatly. How to effectively ensure the output voltage of the on-board battery and how to effectively keep the on-board battery A stable and reliable output voltage to the motor is also a difficult problem. At the same time, it is also difficult to effectively realize the shift control of electric vehicles.
