SS130502-4MWh-1331.2V3000A(300AH10P416S)-20GP-300Ah1P52S-8S-10P(0.5P)

Name: SS130502-4MWh-1331.2V3000A(300AH10P416S)-20GP-300Ah1P52S-8S-10P(0.5P)
Brand: Eco Power Group
Rating: 4.4 (5 reviews)

The 4MWh 20 foot liquid cooled container energy storage system consists of 10 clusters of 1331.2V/300Ah battery clusters, combiner distribution cabinets, fire protection systems, battery management systems, and temperature and humidity control.

Adopting standard non-walk-in 20-foot container, the modular design enhances the utilization of space in the container. The advanced liquid-cooling cycle design concept enables the battery system to perform optimally; the three-level intelligent fire protection system minimizes the risk of thermal runaway of the system, which effectively improves the all-round safety of the energy storage system and the life cycle of the storage battery, and provides a safer technical guarantee for the operation of the energy storage system.

The total weight of a single energy storage container system is about 35.5t, with dimensions of 6058mm in length, 2438mm in width, and 2896mm in height. The nominal voltage is 1331.2V. The shape of the container is shown in the following figure:

Due to the large weight and size of the container itself, it generally does not need to be fixed. However, containers have relatively high requirements for installation foundations, and the bottom of the container must have a concrete foundation with sufficient strength and flatness. The foundation should meet the requirements of GB 50204-2015 "Code for Acceptance of Construction Quality of Concrete Structures". During container installation, sufficient support area and bearing capacity are required at the four corners and bottom side beams of the container.
