Sample Verification & Testing

Before mass production, every Zishine solution goes through multi-round sample verification covering electrical performance, environmental reliability and safety abuse testing. We deliver complete, quantified test reports to make every design decision data-backed and every delivery risk-free.

Sample Verification Services

Electrical Performance Testing

Capacity grading, internal resistance, charge/discharge curves, cycle life and low-temperature discharge performance testing. Every parameter is quantified and recorded for batch comparison.

Environmental Reliability Testing

High/low temperature storage, thermal shock, humidity and vibration testing verify stable performance under extreme environments — from arctic cold to desert heat.

Safety Abuse Testing

Nail penetration, extrusion, overcharge, short circuit and high-temperature baking tests ensure safety even under abuse scenarios, fully compliant with UN38.3 and IEC62133.

EIS Impedance & Consistency Analysis

Electrochemical impedance spectroscopy screens abnormal internal structures and guarantees batch consistency before any order moves to mass production.

Our Verification Advantages

Unlike third-party testing services, our in-house verification platform supports rapid multi-round iteration. Every test is quantified and archived — from electrical parameters to safety margins — providing complete data traceability for customers and accelerating the journey from sample to mass production. Independent laboratories, complete equipment and vehicle-grade standards ensure every customized battery solution is safe, consistent and ready for the market.

VERIFICATION PROCESS
