Description of drawings
Fig. 1 is the structured flowchart of the utility model.
The specific embodiment
Below in conjunction with concrete accompanying drawing and embodiment the utility model is described further.
As shown in Figure 1: the utility model driving engine 1, electrical generator 2, rectifier 3, inverter 4, induction motor 5, dynamometer 7, operation display instrument 8, entire car controller 9, battery pack 10 and battery management unit 11.
As shown in Figure 1: in order to make existing Electrical Bicycle can have travelled distance far away, the utility model comprises the battery-driven car body and is positioned at intrinsic induction motor 5 of said battery-driven car and battery pack 10; Said induction motor 5 links to each other with battery pack 10 through inverter 4; Said battery pack 10 links to each other with the power end of driving engine 1; The output shaft of said driving engine 1 links to each other with electrical generator 2, and the electric energy of said electrical generator 2 outputs links to each other with inverter 4 and battery pack 10 through rectifier 3; Battery pack 10 links to each other with entire car controller 9 through battery management unit 11, and the mouth of said entire car controller 9 links to each other with driving engine 1, electrical generator 2, inverter 4 and induction motor 5; When the electric energy in the battery pack 10 are lower than in the entire car controller 9 preset value; Entire car controller 9 start the engines 1; And driving electrical generator 2 through driving engine 1, said electrical generator 2 provides required work energy through rectifier 3, inverter 4 for induction motor 5, and battery pack 10 is charged.
The mouth of said induction motor 5 links to each other with change speed gear box 6, and said change speed gear box 6 links to each other with dynamometer 7, and dynamometer 7 and induction motor 5 all link to each other with operation display instrument 8; Said operation display instrument 8 links to each other with entire car controller 9.
Said entire car controller 9 links to each other with driving engine 1, electrical generator 2, inverter 3, induction motor 5 and battery management unit 11 through the CAN bus.Said rectifier 3 comprises rectifier diode.Entire car controller 9, dynamometer 7 and operation display instrument 8 all can adopt original structure in the battery-driven car body, no longer detail here.
