As the name implies, new energy vehicles (NEVs) are vehicles featuring new technologies and structures that utilize novel automotive fuels as their power source; the term primarily refers to electric vehicles that have achieved technological maturity and large-scale market adoption. Recognized as a preferred solution for addressing challenges related to exhaust emissions and energy supply, automotive manufacturing is rapidly shifting toward new energy vehicles, with electric vehicles at the forefront. Consequently, automotive component manufacturers are witnessing a distinct shift in market demand for new equipment, structures, and parts, highlighting the growing importance of accurately measuring these components and assemblies.
3D scanners—capable of both 3D dimensional profile scanning and large-scale 3D photogrammetry—enable rapid, accurate 3D scanning of components with complex curved surfaces and geometries, providing precision 3D measurement technologies and solutions for the manufacturing of new energy vehicles and their parts.
For whole-vehicle inspection and reverse engineering, these scanners utilize blue-light 3D scanning technology to capture images from various angles and scan areas with complex local profiles; the resulting data is then input into software for analysis and processing, enabling 3D modeling and dimensional inspection of the entire vehicle.
For power control units, 3D scanners can be used to measure dimensional deviations in intricate components, assess assembly gaps and fit tightness, and effectively measure and verify welding-induced deformation.
Regarding automotive sheet metal stampings, the stamping process often leads to deformations—such as scratches, dents, bending issues, and wrinkles. By scanning the parts to generate 3D models and comparing them against the original CAD data, 3D scanners can precisely identify deviation values. This facilitates process corrections and adjustments, ensuring tighter, seamless assembly and better adherence to design standards and aesthetic requirements.
Regarding the PCU motor controller cover plate—which houses numerous iron cores, copper windings, and insulating materials, and typically features a housing design with spiral grooves and curved surfaces—inspecting its 3D dimensional accuracy is crucial for assembly. A 3D scanner can be used to scan the cover plate; the resulting 3D model is then compared against the original 3D CAD design file to determine precise dimensional deviations.
Regarding electric motor core inspection, 3D inspection systems can efficiently measure both individual stamped laminations prior to stacking and the assembled stacked cores; these systems are capable of measuring everything from thin, flat individual laminations to distortions and misalignments in the stacked assemblies.
On-board chargers are primarily composed of various components such as cover plates, connectors, housings, and relays. 3D scanners, which offer high-precision measurement capabilities, can measure the 3D dimensions of these parts, thereby facilitating component design, simulation and validation, deviation correction, and mass production.
