What is the whole process of electric vehicle production? The quality depends on these links

Everyone has been riding electric bikes for so long, and many people don't know how electric bikes are produced. In fact, the production process of electric vehicles is very simple, and manual and machine assembly are the core links. However, these aspects are closely related to the factory quality of electric vehicles. Today, I will take you to find out.

The process of electric vehicle production is different between large factories and small factories. large factories has a longer production chain. Generally, core parts such as frames, motors, and batteries are produced and manufactured by themselves. However, most manufacturers do not have this capability, and they are assembled through the procurement of parts and components.

Purchasing raw materials before leaving the factory is the first step, which mainly includes plastic parts, frame steel, motor copper wires, stators, motor covers and other components.

The second step is the processing and assembly of core components: the final frame is formed by robot welding, pipe bending, assembly, and electrophoresis painting. The motor completes the winding of the copper wire stator through automatic winding equipment. Finally, the magnetic steel and metal cover are installed, and the motor protection is injected. With corroded and lubricated liquid oil, the motor assembly is completed. The shell of the plastic part needs to be sprayed with baking varnish, and finally a kit is formed to prepare for the assembly of 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, front fork, shock absorption, brake, controller, and wiring harness are installed in sequence through the assembly line. Plastic parts such as installation, lamps, seat barrels, shells, etc.

The fourth step is the off-line inspection stage after the vehicle is assembled. Inspectors carry out load-bearing tests on tires, brakes, shock absorption, handlebars, water spray, and load. Vehicles that pass the test enter the next step, which is packaged and shipped in the warehouse. According to the model of the bike, the packing and delivery link will place the certificate, warranty card, and bike accessories inside.

In the fifth step, after the dealer places an order through the enterprise system, the enterprise will generate an invoice, and the logistics department will make a unified delivery.

This is basically the whole process of leaving the factory for electric vehicles. The quality of electric vehicles mainly depends on the selection of materials for electric vehicle parts, the consistency of product processing of core parts such as motors and frames, and the strictness of production and assembly testing.
