Explore our leading high energy density lithium batteries optimized for Bulgarian cold climates, industrial automation, and smart grid storage.
Bulgaria is strategically positioning itself as a key technological and manufacturing hub within Eastern Europe. Under the guidance of the European Green Deal and the Bulgarian National Recovery and Resilience Plan, the country is undergoing a profound energy transformation. As coal-fired power plants phase down, the demand for stable, high energy density lithium battery storage systems has surged exponentially across municipal, industrial, and residential sectors.
In key industrial centers such as Sofia, Plovdiv, Varna, and Burgas, smart logistics, light electric vehicles (LEVs), and distributed photovoltaic systems are requiring robust lithium-ion battery integration. High energy density cylindrical cells, notably the 18650 and 21700 formats, have become the standard for modernizing equipment, optimizing automated guided vehicles (AGVs) in smart warehouses, and securing telecommunication base stations across the Balkan mountain ranges.
Furthermore, Bulgaria's geography poses unique environmental challenges. The cold winters in the mountainous regions demand batteries that can operate reliably at sub-zero temperatures without losing capacity. This is where high-performance NCM (Nickel Cobalt Manganese) and LFP (Lithium Iron Phosphate) technologies play a decisive role in keeping the local grid and industrial machinery fully operational.
Our low-temperature lithium cells are specifically engineered to maintain over 80% discharge capacity even at extreme -30°C conditions, ideal for Bulgarian mountain infrastructure.
With the massive expansion of solar PV arrays in Southern Bulgaria, our ECO 50 kW / 104 kWh storage systems provide crucial frequency control and peak load shifting capabilities.
High-rate cylindrical cells power the next-generation of industrial AGVs, electric bikes, and power tools driving Plovdiv's economic zones.
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.

How high energy density lithium technology is shaping the commercial and municipal infrastructure across Bulgaria.
Plovdiv's economic zones are witnessing massive growth in automated warehousing. To run 24/7, AGVs and forklifts rely on high-rate 21700 lithium cells. Our NCM/NCA 21700 50Y cells offer ultra-high discharge rates and high capacity, minimizing charging downtime and maximizing logistics throughput.
Sofia is promoting clean urban transport, resulting in a boom in e-bikes, e-scooters, and electric delivery fleets. High energy density cylindrical batteries such as the 18650 32E and 21700 58E provide the lightweight, compact power required to extend vehicle range while maintaining optimal safety and lifespan.
Off-grid cabins, telecom towers, and environmental monitoring stations in the Balkan Mountains face freezing winters. Traditional batteries fail under these conditions. Our NCM 18650 30L low-temperature cells are specifically formulated to deliver high power and capacity down to -30°C, ensuring continuous operations.
With strict EU environmental regulations, Bulgarian industries are actively replacing heavy lead-acid batteries with high-performance lithium-ion alternatives. Cylindrical cells from Changhong offer superior energy density, a much longer cycle life (up to 2000+ cycles), and zero hazardous emissions. Our advanced production processes, certified under global quality standards, ensure that Bulgarian enterprises receive reliable, world-class battery solutions that comply fully with European directives.
Global certifications ensuring the highest safety, reliability, and environmental standards.
Discover our full range of lithium solutions engineered to deliver optimal capacity, durability, and safety for Bulgarian commercial and industrial systems.
Whether you are developing smart grid storage in Sofia, automating logistics in Plovdiv, or designing portable industrial equipment, Changhong New Energy offers customized high energy density lithium solutions tailored to your requirements.
