New energy vehicle assembly line (NEV-AL)

 

This workshop photo showcases a dedicated mini electric car assembly line built for low-speed new-energy four-wheel passenger vehicles. The main transport system is a heavy-duty plate chain conveyor. Semi-finished mini EVs rest on yellow anti-slip grating work platforms and advance station by station along the straight assembly channel.

The workshop floor uses high-gloss green epoxy paint, marked with yellow-black safety warning lines. A long blue overhead steel truss runs above the whole assembly line. This overhead framework holds industrial fans, workshop lighting, compressed air pipelines and power terminals, delivering air and power supplies directly to each assembly station. Multi-layer metal material racks sit beside every workstation to store fasteners, lubricants, wiring harnesses and exterior trim for quick operator access. Mobile industrial vacuum cleaners and handheld pneumatic fastening tools are deployed on-site for assembly cleaning and torque tightening work.

Production Line Overview & Process Composition

This new energy vehicle assembly line covers the full manufacturing sequence: component feeding, chassis assembly, powertrain installation, body fitting, high-voltage wiring, interior fitting and finished-vehicle performance testing.

Chassis & Powertrain Assembly

The bare chassis is loaded onto the plate chain trolley first. Technicians install suspension assemblies, wheel hubs, drive motors and battery packs. Custom positioning tooling achieves precise alignment between battery modules and motor interfaces to ensure stable power connection.

Body Shell & Exterior Assembly

Workers mount the vehicle body shell onto the completed chassis, then fit front and rear bumpers, headlights, grille, fenders, doors and window glass.

Interior Assembly & Wiring Installation

Install seats, dashboard, steering wheel and door interior trims. Route high-voltage wiring harnesses and low-voltage control cables, and connect all on-board electronic components.

Pneumatic & Fluid Fitting

Fit brake pipelines and cooling assemblies, and fill lubricants. The overhead compressed air piping network feeds pneumatic torque wrenches at each station for repeatable bolt tightening.

Power-on Commissioning & Functional Debugging

Power up the mini EV to test motor response, lighting, horn, wipers, braking system and dashboard readouts, to identify and resolve circuit defects.

Offline Comprehensive Performance Testing

Finished vehicles go through rolling road testing, brake performance inspection, battery function validation and visual quality audit. Non-conforming vehicles are diverted to rework stations for adjustment before packaging and shipment.

Core Advantages of New Energy Low-Speed EV Assembly Line

End-to-End Full-Process Assembly Coverage

The production line supports continuous one-flow manufacturing from raw parts feeding, chassis assembly, body fitting, electrical debugging through finished vehicle inspection. It reduces process handover losses and shortens the total production cycle.

Modular Station Design for Flexible Upgrade

Built on standardized modular workstations, this mini EV assembly line supports adding/removing stations, adjusting line speed and reconfiguring layouts to match changing production volumes. The modular design cuts reengineering costs when launching new vehicle models.

Overhead Centralized Utility Supply (Shown in Workshop Image)

The blue overhead steel truss integrates air pipes, power outlets, cooling fans and lighting. Utilities and tools are positioned directly above operators, eliminating messy ground cables and improving workshop safety and cleanliness.

Intelligent Conveying & Automated Auxiliary Operations

Heavy-duty plate chain conveyance stably supports full vehicle weight without tilting. Collaborative manipulators and pneumatic balancers assist with heavy lifting of battery packs and chassis assemblies. Auxiliary automation reduces strenuous manual work, minimizes human assembly errors and ensures consistent batch quality.

Station-Side Material Storage System

Dedicated multi-layer material racks beside each workstation hold parts, oil cans and consumables nearby. This reduces material fetching travel time for workers and boosts overall assembly throughput.

Main Assembly Workflow of Low-Speed New Energy Vehicle Line

Chassis Loading & Positioning Place bare chassis onto the plate chain conveying platform and lock using positioning fixtures.

Powertrain Installation Mount drive motor, battery pack and suspension assemblies; fit wheel hubs and tires.

Body Shell Mounting Install car body shell on chassis, then assemble doors, windows, bumpers and exterior decorative components.

Interior & Wiring Assembly Fit dashboard, seats and interior trims; lay high-voltage and low-voltage wiring harnesses.

Piping & Fastener Tightening Connect brake and cooling pipelines; use pneumatic torque tools to tighten all critical bolts.

Power-on Electrical Debugging Power on the vehicle and verify all electrical functions.

Offline Full Vehicle Test & Quality Audit Complete rolling test, brake inspection and appearance review. Qualified mini EVs roll off the assembly line. Empty trolleys circulate back to the feeding station.

Application Scope

• Low-speed four-wheel new energy mini cars
