In the early morning of May 7, 2024, the "Y T" wheel of Shanghai Yangshan Port sounded its horn and set sail, carrying the 20-foot 5MWh energy storage cabinet of Company C from Shanghai to Country A. This is another energy storage cabinet export business successfully operated by Sungreen Logistics. What is different is that the energy storage cabinet operated by Sungreen Logistics weighs up to 42 tons, which is a 20HQ standard SOC box of 5MWh, according to relevant personnel of the participating units, this should be the first time for private logistics enterprises to participate in the whole chain to export 42 tons of energy storage cabinet SOC box. This move also marks the success of Sungreen Logistics to open a new channel for 5MWh+ storage cabinet overweight cabinet to sea.

This time, according to the project situation, Sungreen Logistics quickly set up a strong professional team responsible for follow-up, and fully participated in the preparation of storage tank booking data, various certification information consultation, maritime declaration and port filing, domestic logistics and transportation plan formulation, warehouse hoisting and unloading, trailer entering the port, vehicle and ship direct loading and other links. After two weeks of non-unloading efforts, the task was successfully completed, and all the projects were successfully shipped out of the port!

In recent years, the internal volume of the energy storage field is the most obvious in the field of system integration, and it has become an industry consensus to improve the volume energy density of the energy storage system, save parts and reduce manufacturing costs through ultra-large capacity cells. With the gradual mass production of 300Ah+ energy storage cells, 5MWh+ energy storage systems have become the focus of battery manufacturers and system integrators competing to layout.


According to incomplete statistics of related media of energy storage industry, since 2023, CRRC Zhuzhou, Rui Pu Lanjun, Double One force, Xin Wang Da, Vision Energy, Trina Energy storage, billion Wei energy storage, Haichen energy storage, Zhongtian Technology, aerospace lithium, Sunshine power, Nandu power supply, BYD, Chuneng New energy, ZhongChuang New Energy, GCL Group, Sixiang New energy, Tianyi Energy and other more than 40 enterprises have successively launched the 20 size 300 Ah+ Large capacity energy storage battery /5MWh+ energy storage system.

Most of them choose to carry 314Ah energy storage battery, open door design, temperature control, liquid cooling system has become the mainstream.

According to the data, the 20-foot 5MWh energy storage system increases the system capacity by about 35% compared with the current mainstream 20-foot 3.72MWh energy storage system, and can greatly reduce the land area and construction costs.

With the continuous iteration of energy storage system products and technologies, the energy storage system because of the increasing energy density, the weight is also increasing, through the previous 36 tons, across the current 42 tons. With the continuous expansion of foreign market demand, domestic mainstream energy storage manufacturers urgently need to find 42 tons of overweight energy storage cabinet international logistics transportation solutions. How to solve the problem of Marine booking, maritime declaration, port filing, warehouse lifting, dock entry, vehicle and ship direct loading, cabin loading, including the destination port loading and unloading cabinets, gate trailers, etc. have become important influencing factors limiting the export of storage cabinets.


As we all know, in accordance with the International Maritime Dangerous Goods Code, lithium battery storage cabinets belong to 9 categories of dangerous goods, UN3536, and all operation links must be operated in accordance with dangerous goods compliance. Although the Ministry of Commerce issued a document to encourage the export of new energy products and called for creating a good business environment, the Shanghai Maritime Safety Administration has responded to the call to cancel the maritime filing of energy storage cabinets, but the UN38.3 report and test summary of lithium battery products still need to be available. And the port record still follows the previous policy, so the difficulty for export enterprises is how to provide information, what information needs to be provided, in order to comply with the port record of the container energy storage system.


In addition, according to the weight regulations of ordinary COC containers and ports, containers with a total weight of 30480KGS can enter the port normally, and overweight containers with a total weight of more than 30480KGS but not more than 32500KGS can also enter the port, but there may be overweight fines when entering the port. Anything over 32,500 KGS is generally refused entry. Then, as 42 tons of seriously overweight dangerous goods storage tank, how to operate the port and lift the ship is also a very important link.

However, Sungreen Logistics believes that the most difficult point for the export of energy storage cabinets is how to quickly and effectively book shipping space to get pre-arranged. At present, the 42 tons of energy storage cabinets are mostly 20HQ standard SOC boxes, which belong to dangerous goods special cabinets, and belong to overweight special cabinets. Some shipping companies do not accept lithium battery products, some shipping companies do not accept 20HQ boxes, some shipping companies do not accept singular 20HQ boxes, and some shipping companies do not accept overweight cabinets. Different routes, different ships, requirements are different. Today's shipping market, 2M/THE/OCEAN three major alliances, ship sharing phenomenon is common, how to choose an accurate shipping company, in the shortest time to book the fastest shipping space, is the most direct and effective test of an energy storage container freight forwarders.

For energy storage cabinet export enterprises, time is money, time is the market, after breaking through the bottleneck of technology and production, the last need to break through is the logistics bottleneck, only these bottlenecks are broken, in order to the fastest and most effective to seize the global energy storage market. Therefore, choose a professional and have a lot of practical experience and data for reference lithium battery storage cabinet freight forwarding, reduce the cost and time of trial and error, is the most critical link of lithium battery storage cabinet export!

Sungreen Logistics, deeply engaged in the international logistics industry of lithium batteries and new energy, has a long-term and stable cooperative relationship with many domestic leading lithium battery and energy storage enterprises, and has a large number of export logistics operation experience and data of 10 feet /20 feet /30 feet /40 feet /45 feet energy storage cabinets, overweight cabinets and super-size cabinets. It can quickly and effectively provide storage tank shipping booking, data certification, maritime declaration, port filing, trailer customs declaration, lifting and storage, trailer entering port, vehicle and ship direct loading, ship loading, destination port lifting and unloading, customs clearance, trailer delivery and other storage tank logistics services!
