Production Capacity Assessment

Monthly production capacity is the core metric for measuring supplier supply capability. Too small capacity may cause unstable delivery, too large may mean supplier relies on few major customers. Recommend choosing suppliers with monthly capacity over 1 million cells, ensuring supply flexibility.

JYOVEX monthly capacity 3.5 million cells, monthly shipment about 2.3 million cells, with ample room for expansion. Factory located in Suqian Economic Development Zone Comprehensive Bonded Zone, enjoying policy benefits and logistics convenience. JYOVEX is an in-house cell manufacturing factory, fully completing the entire chain from cell R&D, production to finished battery assembly, not a PACK assembly factory with outsourced cells.

Quality System Audit

Require supplier to provide ISO9001 certificate, and understand their quality control process. Key checkpoints: IQC incoming inspection standards, IPQC process inspection frequency, OQC outgoing inspection ratio, non-conforming product handling process.

JYOVEX implements full-process three-level inspection (IQC→IPQC→OQC), 100% full inspection before shipment, every battery traceable to raw material batch. 5-year warranty, free return/exchange for quality issues within warranty period.

Certification Qualification Verification

Verify supplier product certifications are complete and within validity period. Key certifications: IEC62133 (safety foundation), CE (EU), UL (North America), UN38.3 (transportation), 3C (domestic).
