Switchable Battery Test Load for Enclosure Condensation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for monitoring and controlling the environment within enclosures containing critical components and backup batteries are costly and space-intensive, as they require separate devices for space heating and battery testing, leading to potential equipment damage and safety hazards due to condensation issues.
Innovation Solution
A combined switchable resistive or active load is used for both space heating and battery testing, controlled by monitoring and control equipment that includes sensors for temperature and humidity, allowing the load to be coupled to either the power source for heating or the battery for testing, thereby reducing component costs and space requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate devices for space heating and battery testing are provided, then the enclosure can maintain proper temperature and test battery functionality, but the system becomes expensive and space-consuming
Solution Approach 1:
The patent combines separate space heating and battery testing functions into a single integrated load device. The load can be switched between two modes: connected to a power supply for generating heat to maintain enclosure temperature, or connected to the battery for discharging and testing battery functionality. This eliminates the need for separate heating elements and battery testing equipment.
Solution Approach 2:
The load device is designed with universal functionality to perform multiple roles. It can operate as a heating element when connected to the power supply, and as a testing load when connected to the battery. The switchable configuration allows one device to replace multiple specialized components, reducing system complexity and cost.
2Adaptability or versatility
If separate devices for space heating and battery testing are provided, then both functions can be performed independently, but component costs and space requirements increase significantly
Solution Approach 1:
The patent merges the heating function and battery testing function into a single load device with switchable connections. The same physical load can be electrically connected to either the power supply (for heating) or the battery (for testing), eliminating the need for separate heating elements, separate testing loads, and associated wiring harnesses for each function.
Solution Approach 2:
The load serves as a universal component that can fulfill both heating and battery testing requirements. By designing the load with switchable connectivity, the system achieves functional versatility without multiplying the number of physical components, thereby reducing both quantity and cost.
3Device complexity
If a common resistance load is used for both space heating and battery testing, then component costs and space requirements are reduced, but the system must switch between functions
Solution Approach 1:
The load system is made dynamic through switchable connectivity. The load can be electrically reconfigured between two states: connected to the power supply for heating operations, or connected to the battery for testing operations. This dynamic switching capability allows the static physical load to adapt to different functional requirements, maintaining versatility while reducing component count.

AI summary
A single common load is provided for both space heating of the interior of an enclosure and for testing of a back-up battery therewith. The common load is coupled to either the battery for momentary load testing thereof, or to a power supply when heat is to be generated by the load for space heating of an interior of an enclosure. Providing only a single load for both space heating and battery testing results in reduced component costs, space savings and simplification of connections and wiring harnesses required. Power resistors, active components such as transistors or MOSFETs, and/or resistive heat tracing may be used as the common load, and deposed within the interior of the enclosure.
