Dec 23, 2025
EV Battery Supplier: ONESUN, a world-renowned battery manufacturer, provides optimal OEM and ODM battery pack solutions for global customers.
With the rapid development of the electric vehicle (EV) industry, the role of EV battery suppliers is becoming increasingly prominent. High-quality battery packs are not only a core guarantee of EV performance but also a key driver of green energy transformation. As a world-renowned battery manufacturer, ONESUN (OneSun Technology (Shenzhen) Ltd.) has become a leader in the global EV battery field with over a decade of industry experience. Founded in 2014 and headquartered in Shenzhen, China, the company focuses on the manufacturing of energy storage batteries and inverters, providing a complete photovoltaic energy storage product solution. ONESUN's products have been exported to more than 70 countries, with a cumulative completed 3GW+ successful projects, a customer satisfaction rate of 90%, an annual production capacity of over 768MW, and a factory area of over 13,268 square meters.
ONESUN's core advantage lies in its strong R&D and technological capabilities. The company's R&D team brings together BMS system engineers from BYD and experts from well-known military and energy companies, independently developing automotive-grade BMS (Battery Management System) with a design life of over ten years. This automotive-grade BMS ensures stable battery operation under harsh environments such as vibration and wide temperature ranges, achieving industry-leading safety and reliability. ONESUN prioritizes quality and safety, using only top-tier (top five Chinese brands) A-grade LiFePO4 (lithium iron phosphate) cells. These cells are renowned for their high safety and lack of thermal runaway risk, making them perfectly suited for electric vehicle power batteries.
In the EV battery supply field, ONESUN positions itself as a global EV battery supplier, focusing on providing advanced power battery systems for electric vehicles. Specific products include power battery packs for golf carts, electric motorcycles, electric bicycles, and electric scooters, as well as 72V and 60V lithium battery packs and LiFePO4 battery packs. These battery packs feature a modular design, support high-voltage stacking, high energy density, and long cycle life, meeting the power requirements of various EV models. ONESUN not only provides standard battery products but also tailors solutions for global customers, covering a full range of applications from residential energy storage to industrial-grade BESS (Battery Energy Storage System).
Particularly noteworthy is ONESUN's outstanding performance in OEM (Original Equipment Manufacturer) and ODM (Original Design Manufacturer) services. As a world-renowned battery manufacturer, ONESUN provides global customers with optimal OEM and ODM battery pack solutions. OEM services allow customers to outsource production based on existing specifications and quickly bring their products to market under their own brand. ODM services involve the design phase, independently developing customized battery packs according to customer needs, including comprehensive optimization of form factor, capacity, voltage, and BMS integration. This flexibility stems from ONESUN's vertically integrated production model: the company owns battery factories, inverter factories, BMS and PCBA production units, perfectly handling battery and inverter integration and communication issues, avoiding compatibility issues.
For global customers, choosing ONESUN means gaining the dual advantages of cost control and quality control. Through excellent supply chain management and integrated applications, ONESUN's products are significantly competitive in terms of cost-effectiveness. Simultaneously, the company offers free customized battery services; if existing models cannot match customer applications, advanced systems such as industrial energy storage units, power walls, stacked modules, or EV power batteries can be quickly developed. Personalized consultation and timely delivery further enhance the service experience, helping customers shorten time-to-market and reduce R&D risks.
In the era of sustainable development, ONESUN extends beyond EV battery supply to include integrated photovoltaic energy storage solutions, such as portable solar power stations and all-in-one energy storage systems. These products complement EV battery technology, driving the deep integration of electric mobility and renewable energy. ONESUN's success stories span the globe, from PayGo's solar rental system in Africa to home energy storage in Europe, demonstrating its international vision and adaptability.
In short, as an EV battery supplier and a globally renowned brand battery manufacturer, ONESUN leverages its technological innovation, production capabilities, and customized services to provide global customers with optimal OEM and ODM battery pack solutions. Looking ahead, as the EV market continues to expand, ONESUN will continue to lead the industry, providing safer, more efficient, and greener battery technologies to support the global energy transition.
