Specific contradictions:
General conflict description:
Principle concept:
If a large number of battery packs are arranged in a limited space, then the battery module density is improved, but the heat dissipation performance deteriorates due to insufficient heat dissipation space
Why choose this principle:
The patent introduces vertical heat dissipation channels between battery packs, transforming the traditional horizontal heat dissipation approach into a three-dimensional structure. The heat dissipation grooves are formed on the side walls of battery packs, creating vertical pathways for heat and coolant flow, thereby improving heat dissipation efficiency without increasing horizontal space occupation.
Principle concept:
If a large number of battery packs are arranged in a limited space, then the battery module density is improved, but the heat dissipation performance deteriorates due to insufficient heat dissipation space
Why choose this principle:
The heat dissipation grooves are integrated into the side walls of the battery packs themselves, nesting the heat dissipation structure within the battery pack geometry. This allows the cooling channels to be embedded within the existing battery pack structure, maximizing space utilization while maintaining effective heat dissipation pathways.

Abstract
The present invention provides a battery module, a battery device, and a battery system having a thermal management design. It utilizes a three-stage thermal management design of the battery module, the battery device, and the battery system to not only prevent the battery cells from being influenced by the external thermal environment, but also efficiently control the temperature of the battery cells, such that the battery cells can reach the requirements of temperature equalization and appropriate operating temperature. The temperature control design of the battery module is mainly a design of a battery cell charging and discharging circuit having heat exchange. The temperature control design of the battery device is mainly a battery device enclosure having a thermal insulation ability, so as to avoid or reduce the influence of the external environment on the temperature of the battery module. The temperature control design of the battery system mainly comprises a temperature control medium circulation system which can enable the temperature-controlled temperature control medium to exchange heat with the battery module by means of the battery device.
