Principle of temperature control system of energy storage container

The containerized energy storage battery system comprises a container and air conditioning units. Within the container, there are two battery compartments and one control cabinet. Each battery compartment contains 2 clusters of battery racks, with each cluster consisting of 3 rows of battery racks.

However, the need for efficiency and convenience in transportation restricts the application of some temperature control technologies that necessitate additional mechanical equipment or real-time external energy input, such as vapor compression refrigeration and electric heating.

This suggests that when the temperature differences among the storage spaces are significant, more energy may be employed to negate the negative effects of temperature interactions. Moreover, a specific type of PCM can only strictly control the temperature of a single zone 19, 20, 21, 28, 29, 30.

Select a commercial thermal insulating container of an appropriate size for their storage. Leave sufficient space for the integration of a multi-temperature control system. Thus, the structural parameters of the system ( ( {d}_ {epsilon, {i,j}})) can be established.

To achieve multi-temperature control, we set the heat source's temperature higher and the cold source's temperature lower than the maximum and minimum temperature requirements of all zones, respectively. This operation creates a temperature difference between the left and right ends of the system.

Implementing multi-temperature control systems is crucial for maintaining high efficiency in various critical domains such as goods transportation 1, cold chain logistics 2, 3, 4, battery thermal management 5, building environment 6, and thermal energy storage 7, 8, 9, 10, 11.
