Problems solved by technology

Nickel-cadmium battery has low discharge internal resistance, but its inherent charge and discharge memory characteristics and serious potential pollution make it unsuitable as an energy source for mopeds
Ni-MH battery overcomes the pollution shortcomings of Ni-Cd battery, and the specific energy has been improved, but its price is high, self-discharge is serious, the energy density is still not high enough, and the performance-price ratio does not have an advantage
Lithium battery has high specific energy and excellent performance compared with other batteries, but its performance as a power battery is not stable enough at present; the high price also makes it impossible to be popularized on a large scale
In short, using batteries as power has a series of problems such as short mileage, short service life, high price, and high proportion of self-weight.

Embodiment Construction

[0037] The invention relates to an integrated hybrid power system, which is an organic combination of an internal combustion engine, an electric motor and an electronic power converter, and is oriented to the driving of light vehicles, and is mainly used for clean power systems of mopeds and motorcycles. The integrated hybrid power system can also be used as a clean power source for light vehicles and small machinery such as tricycles, small sightseeing cars, forklifts and other logistics handling platforms, as well as other low-speed small vehicles that need to be started repeatedly. For the convenience of explaining the problem, the system of the present invention will be described here with mopeds and motorcycles as examples.

[0038] The following is a description of the various parts of the integrated hybrid system.

[0039] like figure 1 As shown, it includes: internal combustion engine power system, electric drive system, mechanical transmission system, and integrated ...

Abstract

A gas-electric power integrated power system for light communication means is composed of integrating control system, electric drive system for low speed, IC engine system for high speed, and mechanical transmission system.

Description

Technical field [0001] The invention relates to a gas-electric integrated hybrid power system of a light vehicle. Background technique [0002] Bicycles are the main short-distance means of transportation for the public, and they tend to develop toward electric vehicles (the main difference lies in the increase in power, weight, speed, etc., which will not be treated differently in the following descriptions); and motorcycles (including Qingqi) It is very popular in rural areas and small and medium-sized cities for personal transportation. [0003] With the expansion of urban space, the increase of mobility and the improvement of living standards, the demand for power-type light vehicles is becoming increasingly urgent. At present, the typical power type personal vehicles are two kinds of mopeds, fuel type and electric type. [0004] Fuel mopeds were once popular in the 1990s, but due to the serious exhaust pollution and loud noise of fuel engines, especially two-stroke fu...
