Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If functional areas (temperature control compartment and power distribution compartment) are partitioned separately from battery packs, then safety and thermal management are improved, but space utilization and integration are reduced
Solution Approach 1:
The container body is divided into a battery compartment and a functional area compartment through a partition plate. The functional area compartment is further divided into a temperature control compartment and a power distribution compartment. This segmentation isolates battery packs from thermal management and power distribution devices, improving safety by preventing interference and hazards between different functional areas while maintaining organized spatial distribution.
2Reliability
If functional areas are partitioned separately, then electrical isolation and safety are improved, but internal space utilization is reduced
Solution Approach 1:
The partition plate extends along the height direction of the container body, utilizing the vertical dimension to achieve electrical isolation between the battery compartment and functional area compartment. This vertical segmentation allows maximum utilization of the horizontal internal space for battery pack placement while maintaining effective electrical isolation through the height-direction partition.
3Quantity of substance
If more battery packs are placed in the container, then energy storage density is improved, but thermal management and safety risks increase
Solution Approach 1:
The temperature control compartment acts as an intermediary between the battery packs and the thermal management system. It houses the liquid cooling unit and facilitates heat dissipation from battery packs through dedicated thermal management pathways. This intermediary structure enables effective thermal management of high-density battery configurations by providing specialized cooling infrastructure separated from but dedicated to battery thermal control.
4Device complexity
If cluster control box is placed in battery compartment, then integration is improved, but safety risk from electrical sparking increases
Solution Approach 1:
The cluster control box is extracted from the battery compartment and relocated to the power distribution compartment within the functional area. This extraction removes the electrical control device from proximity to battery packs, eliminating the safety hazard of electrical sparking near flammable gases. The control box remains functionally integrated through electrical connections while achieving spatial separation for safety.

AI summary
This application provides an energy storage container and an energy storage system. The energy storage container includes a container body, and two compartments are adjacently arranged in a length direction of the container body. One compartment is a battery compartment used for battery packs, and a temperature control compartment and a power distribution compartment are adjacently arranged in a height direction of the container body in the other compartment. The temperature control compartment is stacked above the power distribution compartment. The temperature control compartment is configured to accommodate a liquid cooling unit. The power distribution compartment is configured to accommodate an adapter cable device, a fire extinguishing device, and a power distribution device. Therefore, internal space of the battery compartment is continuous, and accommodates only a battery cluster, to implement electrical isolation. Therefore, the battery cluster can be placed in the battery compartment, to improve space utilization of the battery compartment, improve energy storage density of the energy storage container, and perform unified thermal management on the battery cluster. In addition, a battery layout of the battery compartment can be designed based on sizes of the battery packs.
