As a manufacturer serving the global market, ONESUN places particular emphasis on its OEM/ODM customization capabilities. Unlike traditional "private label" manufacturing, ONESUN's engineering team can design the battery pack's voltage, capacity, size, structure, and system interface protocols according to specific customer needs, providing a one-stop service from conceptual design, prototype manufacturing, testing and verification to mass production. Whether it's electric bicycles, light electric vehicles, industrial vehicles, or high-performance electric vehicle power batteries, ONESUN can provide matching solutions, truly achieving "customization on demand and precise matching."
In the OEM (contract manufacturing) model, ONESUN boasts fully automated production lines and a comprehensive quality management system. From cell testing and assembly to final battery pack inspection, every process is digitally tracked and rigorously tested, ensuring that products meet international certification standards such as UL, CE, and UN38.3. This is a highly attractive advantage for brand customers seeking standardized exports to global markets. Through strict quality control and extensive export experience, ONESUN's products have been exported to over 70 countries and regions in Europe, the Middle East, Africa, and Southeast Asia.
In terms of ODM (Original Design Manufacturing) services, ONESUN focuses not only on the basic functions of the product but also on high-value-added designs such as battery intelligence, system integration, and thermal management. For example, its independently developed intelligent BMS (Battery Management System) can monitor voltage, current, temperature, and charge status in real time, and optimize discharge strategies for different application scenarios, significantly improving the safety and lifespan of the entire battery system. This deep integration design, from hardware to software, ensures that customers receive not just a battery pack, but a reliable, efficient, and scenario-appropriate overall energy solution.
In today's competitive market, service is also a crucial component of brand value. ONESUN places great emphasis on technical support and local service capabilities for its global customers. Through a professional team, it provides timely technical consulting, solution optimization suggestions, and a comprehensive after-sales support system, ensuring that customers have no worries during product deployment and use. This "full lifecycle support" model makes ONESUN a preferred supply partner for many startup brands, system integrators, and even large multinational corporations.
In summary, as an internationally renowned EV battery supplier, ONESUN, with its solid technical foundation, integrated manufacturing capabilities, highly flexible OEM/ODM services, and global vision, is providing global customers with more reliable, safer, and more competitive battery pack solutions. Whether in electric vehicles, energy storage systems, or intelligent power equipment, ONESUN is demonstrating its exceptional strength as a global battery pack solution provider through its actual performance.
