Solution Overview
Problem
Existing batteries face issues with heating of battery poles and connections, leading to increased resistance and potential damage, especially when used in high-performance applications.
Innovation Solution
The battery design involves leading the battery poles out through the battery inlet and outlet, where they are surrounded by a temperature control medium to dissipate heat, reducing heating and increasing the battery's suitability for high-performance applications by maintaining a homogeneous temperature distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If battery poles and connections are used in high-performance applications, then power output and energy storage capacity are improved, but heating increases leading to increased resistance and potential damage
Solution Approach 1:
The patent extracts the battery poles from the traditional battery housing structure and leads them out through the inlet and outlet openings. This allows the poles to be directly exposed to the temperature control medium flowing through the battery, enabling effective heat dissipation while maintaining high power output capability
Solution Approach 2:
The temperature control medium acts as an intermediary between the battery poles and the external environment. By flowing through the battery housing and surrounding the poles, it mediates heat transfer, carrying away excess heat generated during high-performance operation without requiring direct contact between poles and external cooling systems
2Temperature
If battery poles are led out through the housing, then heat dissipation is improved, but structural complexity increases
Solution Approach 1:
The battery housing is designed with multi-functionality: it serves as both the structural enclosure for the battery cells and as a temperature control system. The inlet and outlet openings, originally just structural features, are repurposed to serve dual functions as both cell access points and cooling medium flow paths, eliminating the need for separate cooling system components
Solution Approach 2:
The patent merges the structural housing function with the thermal management function. By integrating the temperature control medium flow paths through the housing structure itself and leading the battery poles directly through the same structure, it combines what would traditionally be separate systems into a unified design, reducing overall complexity
3Stability of the object's composition
If temperature control medium flows through battery interior, then temperature uniformity is improved, but electrical insulation requirements increase
Solution Approach 1:
The temperature control medium serves as an intermediary that provides both thermal contact and electrical insulation. It surrounds the battery poles and connections, enabling heat dissipation while maintaining electrical isolation between the conductive components and the housing structure, thus addressing both thermal management and electrical safety requirements
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design effectively reduces heating of battery poles and connections, enhancing the battery's performance and service life by maintaining a consistent temperature, making it suitable for both high pulse and continuous outputs.
Implementation Method 1
the battery poles are thus surrounded by a temperature control medium during battery operation, which cools the battery poles and thus dissipates heat generated in the battery poles
Implementation Method 2
A temperature control medium flows into the battery interior through the battery inlet and flows out of the battery interior through the battery outlet
Implementation Method 3
Since each of the battery terminals and conductors has an electrical resistance, the current generates heat in the battery terminals and conductors

AI summary
A battery (1) is shown and described, comprising a plurality of cells (2), a battery housing (3), a first cell connector (4), a second cell connector (5), a first battery terminal (6), a second battery terminal (7), a battery inlet (8), and a battery outlet (9) for a temperature control medium. Each cell (2) has a first cell contact (13) on a first surface of the cell (2) and a second cell contact (14) on a second surface of the cell (2) opposite the first surface. The battery housing (3) has a battery base (10), a battery support (11), and a battery cover (12). The battery base (10), the battery support (11), and the battery cover (12) enclose a battery interior (15), sealed for a temperature control medium except for the battery inlet (8) and the battery outlet (9). The cells (2) are arranged within the battery interior (15) to be surrounded by a temperature control medium.On the one hand, each of the first cell contacts (13) and the first cell connector (4) are electrically connected, and on the other hand, each of the second cell contacts (14) and the second cell connector (5) are electrically connected. On the one hand, the first cell connector (4) and the first battery terminal (6) are electrically connected, and on the other hand, the second cell connector (5) and the second battery terminal (7) are electrically connected. The invention solves the problem of providing a battery (1) in which the heating of the battery terminals (6, 7) and the connections is reduced compared to the prior art. This problem is solved by the fact that the first battery terminal (6) is led out of the battery interior (15) through the battery inlet (8) and the second battery terminal (7) through the battery outlet (9).
