Discover our high-efficiency cylindrical lithium-ion cells and eco-friendly primary batteries, tailored to match the evolving energy demands of Bulgarian smart grids, electric mobility, and telecommunications.
As a key hub in Southeastern Europe, Bulgaria is accelerating its transition towards green energy, smart city infrastructures, and clean transportation.
With the Bulgarian government pushing for massive PV installations in regions like Thrace and Dobrudzha, the demand for highly reliable Battery Energy Storage Systems (BESS) is skyrocketing. Our custom-designed lithium-ion battery packs offer the high cycle life and energy density required to smooth out solar intermittency, ensuring stable distribution across the national grid managed by ESO (Electricity System Operator).
Urban centers like Sofia, Plovdiv, and Varna are witnessing a rapid shift towards light electric vehicles (LEVs), electric bicycles, and e-scooters. The implementation of high-rate cylindrical lithium cells (like the 21700 and 18650 series) provides the necessary power output, fast charging capability, and safety standards demanded by municipal transport initiatives and private logistics fleets.
Bulgarian telecommunications providers require robust backup power systems capable of operating during freezing winter temperatures in mountainous terrain like the Balkan and Rila ranges. Our specialized low-temperature cylindrical lithium cells (such as the 18650 25L) are engineered to deliver reliable performance even at sub-zero temperatures, ensuring uninterrupted connectivity.
Custom battery packs are the backbone of modern industrial automation and smart infrastructure in Bulgaria. At Sichuan Changhong New Energy Technology Co., Ltd., we design, engineer, and manufacture battery solutions that directly address the pain points of Bulgarian system integrators and industrial distributors.
Agricultural IoT & Smart Farming: In Bulgaria's fertile agricultural plains, IoT-enabled sensors, automated irrigation networks, and GPS-guided machinery rely on long-lasting alkaline and lithium-ion batteries. Our eco-friendly LR6/AA batteries and high-capacity cylindrical cells keep remote sensors active for years, minimizing operational maintenance costs.
Automotive & Light Industrial Zones: The Trakia Economic Zone (TEZ) in Plovdiv has emerged as a powerhouse for automotive components and electronics. Our high-rate power cells (like the 18650 25T and 21700 50SE) are perfect for integration into automated guided vehicles (AGVs), industrial power tools, and robotic systems operating in modern Bulgarian smart factories.
Home Energy Storage Systems (HESS): With rising electricity costs and the EU's push for residential energy independence, Bulgarian homeowners are increasingly adopting solar-plus-storage solutions. Custom battery packs built from our 21700 high-capacity cells offer an optimal balance of compactness, thermal safety, and longevity for residential wall-mounted batteries.
Smart Metering & Municipal Infrastructure: Water utilities and gas distributors in major Bulgarian municipalities are upgrading to smart metering networks. These devices require highly stable primary batteries that can operate maintenance-free for over a decade. Our high-performance alkaline range provides the exact reliability and discharge profile required for these long-term utility deployments.
Sichuan Changhong New Energy Technology Co., Ltd. was founded in October 2006. As a subsidiary of Changhong Holding Group (one of the World’s Top 500 Brands), it is a national high-tech enterprise integrating R&D, manufacturing and sales of full-range alkaline batteries and lithium-ion batteries.
The company now operates six manufacturing bases in Mianyang (Sichuan), Jiaxing (Zhejiang), Taixing (Jiangsu), Huarong (Hunan), Shenzhen (Guangdong) and Chonburi (Thailand). It has an annual production and sales capacity of 3.5 billion alkaline manganese batteries, 600 million cylindrical lithium-ion batteries (including 18650, 21700, 26700 and other models), over 100 million small polymer batteries and over 100 million battery PACK sets.
It controls three subsidiaries: Zhejiang Changhong Feishi Electrical Appliance Industry Co., Ltd., Changhong Sanjie New Energy Co., Ltd., and Shenzhen Changhong Juheyuan Technology Co., Ltd.
The company is a listed enterprise in China (Stock Code: 920239), Top 100 Chinese Battery Companies, Vice Chairman Unit of China Battery Industry Association, Member of IEC Technical Committee on Primary Batteries, National High-Tech Enterprise, National Specialized, Sophisticated, Unique and New "Little Giant" Enterprise, the largest production base of high-rate cylindrical lithium batteries in Western China, National Green Factory, Sichuan Provincial Advanced Smart Factory, and included in the MIIT 5G Factory List.

Our manufacturing excellence is backed by rigorous international standard certifications, ensuring that all battery packs shipped to Bulgaria meet European Union directives.
Building high-performance battery packs for industrial applications requires a deep understanding of cell chemistry, thermal management, and battery management systems (BMS). Sichuan Changhong New Energy Technology Co., Ltd. provides comprehensive OEM/ODM solutions tailored to the strict quality and ecological standards of the European Union, making us a preferred partner for Bulgarian engineering firms.
Our lithium-ion cylindrical cells utilize Nickel Cobalt Manganese (NCM) and Nickel Cobalt Aluminum (NCA) chemistries. These formulations offer the highest energy density currently available for commercial applications, allowing Bulgarian system designers to build lighter and more compact battery packs for electric vehicles and portable medical equipment.
All custom battery packs intended for the Bulgarian market are designed with multi-level safety mechanisms, including current interrupt devices (CID), positive temperature coefficient (PTC) resistors, and advanced BMS integrations. This ensures full compliance with European CE directives, RoHS, and UN38.3 transport safety regulations.
As Bulgaria positions itself as a major logistics corridor between Europe and Asia, the local supply chain requires rapid, cost-effective, and highly reliable battery component manufacturers. With our new state-of-the-art production facility in Thailand and established operations in China, we offer Bulgarian businesses diversified sourcing routes, mitigating geopolitical risks and tariffs. Our massive production capacity guarantees a stable supply of high-rate cylindrical cells, preventing project delays for large-scale municipal and industrial installations in Bulgaria.
