Assembled generator and range extender

Abstract

The invention discloses an assembled generator and a range extender, the generator comprises a motor shell, a rotor shaft, a rotor and a stator winding arranged in the motor shell, and an adapter box, the rotor and the stator winding are arranged side by side in the axial direction, and the end part of the motor shell is provided with a first bearing for supporting the rotor shaft; the switching box comprises a current output end used for outputting current of the generator, and the controller comprises a control input end electrically connected with an output line of the generator and a control output end electrically connected with the current output end. The range extender comprises an engine, the generator and a controller, an output shaft of the engine is in transmission connection with a rotor shaft of the generator, and a motor shell of the generator is connected with an outer shell of the engine. Maintenance, disassembly and assembly in the use process are facilitated, the overall occupied space can be saved, meanwhile, the power of the generator can be conveniently adjusted according to the actual use requirement, and therefore the generated power of the generator can be matched with the actual electricity utilization requirement.

Description

technical field [0001] The invention relates to the technical field of generator manufacturing, in particular to an assembled generator and a range extender. Background technique [0002] With the improvement of people's awareness of environmental protection, electric vehicles using lithium batteries have begun to enter thousands of households. Due to the limitations of lithium battery technology and performance, there are still two main problems in electric vehicles: First, the cruising range of lithium batteries is limited. , Correspondingly, the charging time of lithium batteries is long, and fast charging cannot be achieved like refueling, and the number of suitable charging piles is limited, resulting in troublesome charging. The above technical problems limit the popularization of electric vehicles. For this reason, someone has invented a range extender suitable for electric vehicles. The existing range extender usually includes a generator, and the power of the genera...

[0002] With the improvement of people's awareness of environmental protection, electric vehicles using lithium batteries have begun to enter thousands of households. Due to the limitations of lithium battery technology and performance, there are still two main problems in electric vehicles: First, the cruising range of lithium batteries is limited. , Correspondingly, the charging time of lithium batteries is long, and it is impossible to achieve fast charging like refueling, and the number of suitable charging piles is limited, resulting in troublesome charging. The above technical problems limit the popularization of electric vehicles

[0003] However, the existing range extenders have the following technical defects: On the one hand, due to the large size of the battery on the electric vehicle, the battery is usually installed in the trunk of the car body and the front cabin, which will cause tension in the installation space in these areas

On the other hand, the range extender also needs to be equipped with a small engine, which leads to more crowded installation space

In the prior art, people usually connect the engine and the generator coaxially in series to simplify the structural design and layout, but this will increase the axial size of the entire range extender, which in turn causes inconvenience and difficulty in installing the range extender on the car
