AI-Powered supplier vetting

SummaryThe supplier is identified as a trading company operating in battery, battery-component, new-energy technology, and energy-storage-related businesses. It reports professional technical R&D capability, 17 patents, environmental labeling product certificates, broad customization services, and stated production capacities across batteries, jump starters, and energy-storage systems. However, it does not provide 3D software design services or an SDK, and its quality-assurance system is explicitly absent. Complaint handling, service procedures, corrective actions, and supplier approval controls exist only in incomplete documented form. Financial information is represented only by year labels, so credibility cannot be determined. Overseas service infrastructure is limited: no overseas warehouse, showroom, agent, or branch is reported.

CertificationsThe company description states that the supplier holds environmental labeling product certificates, but it does not identify the certificate standards, products covered, validity, or any other certification details. The evidence supports holding at least some certification, but not whether it satisfies a specific certification requirement.

R&D capabilityThe supplier is identified as a professional technical supplier, conducts new-energy technology R&D, and reportedly holds 17 patents. However, it does not provide 3D software design services and has no available SDK, so innovation capability is evidenced but technically limited in these areas.

Production capacityThe supplier reports annual capacities of 5,000 units for 72V50Ah electric-motorcycle lithium batteries, 5,000 units for 48V100Ah telecom rack lithium-ion batteries, 50,000 units for 12V jump starters, 1,000 units for 10kW/30kWh all-in-one energy-storage systems, and 100 units for 215kWh/100kW BESS. It also states battery-component production within its business scope.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. These services are reported both under R&D-supported design services and general design-services capability.
