How OKAI Ensure Quality in Vehicles Made

About OKAI Laboratory

OKAI boasts industry-leading testing capabilities, supported by a state-of-the-art laboratory that covers the entire e-scooter and e-bike industrial chain. With a total investment of 15 million yuan, the lab operates nearly 200 internationally advanced testing instruments, including high-frequency vibration test systems, optical emission spectrometers, coordinate measuring machines (CMMs), wind-tunnel chassis dynamometers, industrial X-ray inspection systems, and 3D scanners—each valued at over 500,000 yuan.

Comprehensive Quality Infrastructure

This comprehensive quality infrastructure spans from macro to micro testing, enabling full-vehicle evaluations for performance, durability, and extreme-environment reliability, as well as detailed inspections of every critical component to meet stringent standards for structural integrity and electrical safety.

Rigorous Testing Standard

The lab conducts more than 40 categories of tests across vehicles, battery packs, and individual cells. Even the smallest screw is subjected to rigorous validation to ensure every OKAI product delivered to customers reflects the industry’s highest benchmarks for safety, reliability, and outstanding performance.

X-Ray Inspection System

- Key Advantages: Non-destructive internal inspection, dimensional measurement, thickness and density evaluation

- Primary Applications: Quality control, failure analysis, scientific research


Our X-ray inspection system leverages the strong penetrating capability of X-rays to examine internal structures without damaging the sample. It can precisely detect micron-level internal defects such as porosity, cracks, voids, and inclusions. In addition to imaging hidden structures, the system supports accurate dimensional measurement as well as quantitative analysis of material thickness and density distribution.

Optical Emission Spectrometer

- Wide Testing Capability: Detects multiple metallic elements, alloying elements, and selected non-metallic elements

- Quality Assurance Applications: Incoming material inspection, alloy composition adjustment, finished product composition verification, and metal failure analysis


Our direct-reading Optical Emission Spectrometer (OES) operates based on the principles of atomic emission spectroscopy. When atoms in a metal sample are excited by a high-energy source, they emit characteristic spectral lines unique to each element. By capturing and analyzing these spectra, the OES can rapidly and accurately identify and quantify the elemental composition of a material.
