The battery system is mainly composed of battery cells connected in series and parallel: first, several groups of battery cells are connected in series and parallel to form a battery box, and then the battery boxes are connected in series to form a battery module and increase the system voltage.
The key challenges in designing the battery energy storage system container included: Weight Reduction: The container design had to be lightweight yet strong enough to withstand operational stresses like shocks and seismic forces, ensuring the batteries were protected during transport and deployment.
To ensure optimal performance and safety of battery storage system, effective thermal management was a key consideration in the design. We integrated an efficient HVAC system into the container design by: Incorporating two AC chillers to cool the battery area, regulating the temperature inside the container.
Static simulations confirmed the container could safely handle expected operational stresses. The integrated HVAC system maintained the batteries' ideal temperature, improving durability and preventing overheating or freezing. The container was also weatherproof, offering protection against environmental elements.
The battery rack consists of the required number of modules, the Battery Management Unit (BMU), a breaker and other components. The container consists of the required number of the battery racks, as well as air conditioning and fire extinguishing equipment.
The container complies with the ISO standard. The system is installed in 20 ft, 40 ft and containers of other sizes according to the system size, and the containers can be combined together. In this configuration, the system can be transported by trailer on land and by container carrier over water (Figure 2).
The battery is expected to be used not only in a transportation uses such as electric vehicles (EV), but also for stationary energy storage such as in the stabilization of renewable energy, the adjustment of power grid frequency and power peak-shaving in factories.

Our battery energy storage systems (BESS) provide the optimal answer to intermittent energy production. By absorbing excess energy generated during periods of high production, BESS enable a smoother and more reliable integration of renewable energy into the grid, steadily reducing dependence on fossil fuels.
The €250 million (C$371M/US$264M) 240MW/480MWh BESS project is a milestone for France, boasting a capacity nearly five times greater than the country's largest operational system.
With a size of 35 MW and a capacity of 44 MWh, this energy storage solution is poised to revolutionize the region's power dynamics. To put this into perspective, the battery system will store an amount of electricity equivalent to the daily consumption of approximately 10,000 people in France.
Harmony Energy CEO for France Andy Symonds said: “Developing and operating vital battery energy storage facilities across France, will lead to enhanced energy security, more affordable energy bills, and the decarbonisation of the grid. We are excited to commence building works on our first project.”
However, we recognize the inherent challenges when wind stops blowing and clouds are hiding the sun. This is where our cutting-edge battery energy storage solutions come into play. Our battery energy storage systems (BESS) provide the optimal answer to intermittent energy production.
