Dowei Electric Energy Storage BESS

Product catalog summary

General Description:

The document outlines the specifications and standards for Energy Storage (BESS) solutions provided by Ningbo Dowei Electric Co., Ltd.
Compliance with international standards such as IEC62619, UL1973, UL9540A, and UN3536 is highlighted.
Quality certifications include ISO 9001, KEMA, CESI, CE, TUV, UL, and ASTA.
Design considerations include seismic design (IEEE Std 693), structural design (ASTM A325), and high altitude correction (IEC & IEEE standards).
The system features a modular design for flexible power and energy configuration, and is pre-assembled and pre-tested for ease of expansion and service.

Typical Specification:

Utility Energy Storage (BESS) is available in two cell types: LFP/280Ah and LFP/320Ah, with nominal capacities of 3.44MWh and 3.93MWh respectively.
The working voltage range is 960 to 1401.6V, with a charge and discharge rate of ≤0.5P.
Operating ambient temperature ranges from -30℃ to 55℃, and it can function at altitudes up to 4000m.
Cooling is achieved through a combination of air and liquid cooling methods.
Firefighting methods include perfluoro gas firefighting at both cell and cabin levels, backup water firefighting, combustible gas emission, and explosion venting design.
Communication interfaces include Ethernet, CAN, and RS485, supporting protocols like IEC61850, IEC104, CAN2.0, and Modbus.
The system has a protection degree of IP55 and an anti-corrosion grade of C4.
Physical dimensions are 6058mm x 2438mm x 2896mm, with a weight of approximately 34 to 35 tons.
Standards and certifications include IEC62619, UL1973, UL9540A, and UN3536.
