Multi-chamber Battery Testing Apparatus with Independent Explosion-proof Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery testing systems lack independent explosion-proof and fireproof chambers, leading to potential chain reactions and inefficient temperature control, which compromises safety and work efficiency during battery testing.
Innovation Solution
A multi-chamber, independent, explosion-proof, fireproof isolation box with individually controlled temperature in each chamber, featuring a skeletal frame, hingeless doors, and a modular design for easy replacement of battery wiring assemblies and temperature control devices, ensuring that explosions or fires in one chamber do not affect others and allowing for simultaneous testing of batteries under different temperature conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple batteries are placed together in one large box for testing, then testing capacity is improved, but safety is worsened because an explosion or burning in one battery will damage adjacent batteries and equipment
Solution Approach 1:
The test box is divided into multiple independent explosion-proof chambers, each capable of containing a battery separately. This segmentation allows multiple batteries to be tested simultaneously while isolating them from each other, so that an explosion or burning in one chamber will not affect other chambers, thus resolving the contradiction between testing capacity and safety.
2Adaptability or versatility
If a single cabinet temperature control system is used, then device complexity is reduced, but adaptability is worsened because different temperature conditions cannot be provided for different battery types or testing requirements
Solution Approach 1:
The temperature control system is segmented into multiple independent control units, with each explosion-proof chamber equipped with its own temperature control device. This allows each chamber to be controlled independently at different temperatures, providing the adaptability needed for different battery types and testing requirements while maintaining manageable system complexity through modular design.
Solution Approach 2:
Each explosion-proof chamber is equipped with localized temperature control capabilities, allowing different temperature conditions to be applied to different chambers based on specific testing needs. This local quality approach enables customized temperature environments for different battery types without requiring a complex centralized control system.
3Ease of operation
If wiring channels are provided on side walls for connecting battery holders, then ease of operation is improved, but device complexity is worsened due to complicated wiring arrangements and crisscrossed cables
Solution Approach 1:
The wiring assembly is extracted from the traditional side-wall channel configuration and integrated directly into the explosion-proof door structure. This allows the wiring to be organized and connected through the door itself, simplifying the overall wiring arrangement and reducing cable crisscrossing while maintaining ease of operation for connecting battery holders.

AI summary
A cabinet box comprises a plurality of independent, explosion-proof chambers. A battery wiring assembly for receiving and testing a battery is attached to an inner wall of an explosion-proof door, and an electrical connector is provided on an outer wall of the door. The assembly is placed inside a chamber, and the door seals the chamber. The temperature in each chamber is controlled independently, allowing batteries to be tested simultaneously at different temperatures. An air-circulating temperature-control module can be in a chamber, or a temperature controller with a refrigeration sheet can be integrated with the battery wiring assembly for direct battery contact. Separate, independent explosion-proof chambers effectively eliminate the possibility of a battery explosion in one chamber causing a chain-reaction explosion in another chamber. Modularity allows damaged parts to be replaced easily. An external battery testing machine can connected to the connector on each door.
