Advanced Quality Assurance Solutions For New Energy Vehicles

Publication Details

Abstract

The manufacture of new energy vehicles (NEVs) is accelerating at a rate not seen in the automobile industry in the last 100 years. Battery and fuel-cell powered vehicles are quieter and have fewer moving parts, yet meeting the same manufacturing quality standards requires new applications of coordinate measuring machines. First, an overview of current NEV power train architecture will be provided. The measurement challenges of each key component: lithium-ion batteries, battery modules, battery packs, fuel-cell assemblies and power electronics will be shared. Second, the typical manufacturing process for each of these components will be described. The quality gates where insertion of a coordinate measuring machine (CMM) can improve each process will be shown. Uses for traditional tactile and confocal white light non-contact sensors will be illustrated.
