We have been riding electric cars for so long, many people do not know how electric cars are produced.In fact, the production process of electric vehicles is very simple, and manual and machine assembly is the core link. But the quality of electric vehicles has these links are closely related, today we take you to understand.
There is a difference between a large factory and a small factory in the production process of electric vehicles.
The production chain of large factories is longer. Most manufacturers do not have this strength, and they are all assembled through parts procurement.
Purchasing raw materials before delivery is the first step, mainly including plastic parts, frame steel, motor copper wire, stator, motor cover and other parts.
The second step is the processing and assembly of core accessories: the final frame is formed by welding, bending, assembly and electrophoresis painting of the robot; the winding of copper wire stator is completed by automatic winding equipment of the motor; finally, magnetic steel and metal cover are installed and liquid oil of anti-corrosion and lubrication is injected into the motor; the assembly of the motor is completed.The plastic shell needs to be sprayed with baking paint and finally formed into a kit for assembly on the production line.
The third step is the assembly of parts. Different models are assembled on the production line according to certain templates and standards. The hub motor, front wheel, head, front fork, shock absorption, brake, controller and wiring harness are installed successively on the assembly line, followed by the installation of plastic parts such as lamps, seats, barrels and shells.
The fourth step, the vehicle assembly is the off-line detection stage.The tester for tires, brakes, shock absorption, handle, and water, load and other load bearing test, through the test vehicle into the next link, is the warehouse packaging delivery.Depending on the model, a certificate, warranty card, and accessories will be placed inside the vehicle
Step 5. After dealers place an order through the enterprise system, the enterprise will generate an invoice for unified delivery by the logistics department.
This is basically the whole process of electric cars coming out of the factory.The quality of electric vehicles mainly depends on the purchase of electric vehicles accessories materials, motor, frame and other core parts of the product processing consistency and production assembly test of the strict degree.
