A range-extended electric motorcycle

technical field

The present invention relates to a kind of motorcycle. the

Background technique

In December 2009, China took the lead in announcing China's emission reduction target on the eve of the Copenhagen Conference - "By 2020, my country's CO2 emissions per unit of GDP will be reduced by 40% to 45%". This emission reduction target expresses China's The government's firm determination to protect the environment, and the emission reduction target will also play an important guiding role in China's future economic development. On July 1st of the following year, the more stringent National III emission standards for motorcycles were officially implemented. In order to meet the standards, new products adopting the new technology of EFI plus catalyst will inevitably increase the cost of products and bring great benefits to the development of the entire motorcycle industry. With more pressure coming, China's motorcycle industry is facing a new round of tests. the

Since electric motorcycles have better solved the exhaust pollution and urban noise problems of traditional motorcycles, coupled with rising crude oil prices around the world, reducing crude oil consumption and exhaust pollution has become a top priority. Relying on scientific and technological progress, the development of electric motorcycles has important history and reality in curbing oil price increases, supporting national energy development strategies, reducing environmental pollution, promoting the harmonious development of people and the earth, facilitating ordinary people's travel, and relieving urban traffic congestion. significance. However, the disadvantages of traditional pure battery motorcycles such as long charging time, short driving mileage, and short service life of the battery greatly reduce the economical efficiency of its use. the

Contents of the invention

The purpose of the present invention is to provide an energy-saving and environment-friendly extended-range electric motorcycle that can travel long distances. the

In order to achieve the above object, the following technical solutions are adopted: an extended-range electric motorcycle, including a frame and a battery pack, the lower part of the frame is provided with a drive wheel driven by a hub motor, and the battery pack provides power for the hub motor, and is characterized in that: The motorcycle has a vehicle controller, which detects the remaining battery capacity of the storage battery in real time, and the motorcycle also has a range extender, wherein the range extender includes an internal combustion engine and an ISG motor connected by a connecting shaft. After the controller detects that the remaining power of the battery is lower than the specified value, the internal combustion engine starts to run at a constant speed, drives the ISG motor to generate power, supplies power for motorcycle electrical equipment, and uses the remaining power to charge the rechargeable battery pack. the

For the convenience of use, the vehicle controller is provided with a charging circuit that uses a civilian 220V power supply to charge the rechargeable battery pack. the

The design of the whole machine of the present invention is simple and compact, easy to use, and can ensure that the battery pack is used for power supply in most cases, and the range extender works when necessary, so as to achieve the goal of low energy consumption and zero emission (or the lowest emission) to the greatest extent. . the

Detailed ways

Below, the present invention will be further described in conjunction with the accompanying drawings and specific embodiments. the

As shown in Figure 1, a range-extended electric motorcycle is mainly composed of a frame 11, a voltage regulator 9, a battery pack 10, a vehicle controller 13, a hub motor 2, a motor driver 8, a range extender 3, and after driving Wheel 1, front wheel 14, speed control handle 12, seat 7, etc.; among them, battery pack 10 and voltage regulator 9 are arranged in the middle of the frame; range extender 3 and motor driver 8 are arranged in front of driving rear wheel 1 , the lower part of the seat 7; meanwhile, the in-wheel motor 2 is arranged on the driving rear wheel 1. the

As shown in Figure 2, the range extender 3 includes a fuel tank 4, a miniature universal internal combustion engine 5, an ISG motor (Integrated Starter and Generator) 6, etc., wherein the miniature universal internal combustion engine 5 and the ISG motor 6 are connected through a connecting shaft 15. the

When working, the speed control handle 12 controls the speed of the electric motorcycle through the motor driver 8, that is, controls the rotation speed of the hub motor 2, and transmits the information to the vehicle controller 13; The electric quantity is detected, and when the vehicle controller 13 detects that the electric capacity of the battery pack 10 is lower than a given threshold value, the range extender 3 automatically starts generating electricity. When the range extender generates power, the miniature general-purpose internal combustion engine runs at a constant speed to drive the ISG motor to generate power. The range extender 3 starts to generate electricity, and the electric power after the voltage regulator 9 is regulated, at first ensures the power supply of the electrical equipment, such as the hub motor 2, motorcycle lights, etc., and the remaining part is charged to the battery pack 10; according to different control Strategies, for example, when the vehicle stops, the battery power is higher than a certain value, and the range extender 3 stops working. The vehicle controller 13 is also provided with a charging circuit, which can charge the accumulator pack with the civilian 220V voltage. the

The invention is simple and compact in design, easy to use, and can ensure that the battery pack is used for power supply in most cases, and the range extender works when necessary, so as to achieve the goals of low energy consumption and zero emission (or the lowest emission) to the greatest extent. the
