Embodiment Construction
[0043] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments to facilitate a clear understanding of the present invention, but they do not limit the present invention.
[0044] Such as Figure 4 Shown, the workflow of the present invention is as follows:
[0045] Build the engine work reference table as follows:
[0046]
[0047] The table construction process mainly includes:
[0048] Determine the fixed speed value of the engine and determine the power range (that is, the target power generation range of the range extender)
[0049] Determine the fixed speed value of the engine: if image 3 As shown, obtain the external characteristics and universal characteristic curve of the engine, and the maximum engine speed nmax; calculate the best economic zone of the engine according to the external characteristics and universal characteristic curve, generally the engine speed is between 0.2nmax an...
