Battery Pack Bracket Connector Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power battery packs face issues with connector detachment during impact, leading to potential short-circuits and sealing failures due to the weight and vibration of connectors, compromising safety and reliability.
Innovation Solution
A battery pack design featuring a bracket system that securely fixes connectors to the casing, distributing their weight and preventing detachment, while also reducing the overall height and improving sealing reliability through a stable triangular bracket structure and inclined fixing portions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connectors are fixed directly to the casing, then the structure is simple, but the connectors may detach during impact or vibration causing safety issues and sealing failures
Solution Approach 1:
A bracket is introduced as an intermediary component between the casing and connectors. The bracket includes a base fixed to the casing and fixing portions that secure the connectors, acting as a mediator that provides stable mounting while isolating the connectors from direct impact and vibration stresses on the casing.
Solution Approach 2:
The bracket structure is segmented into distinct functional parts: a base for attachment to the casing, fixing portions for securing connectors, and support columns for structural reinforcement. This segmentation allows each part to be optimized for its specific function while collectively solving the overall stability problem.
2Use of energy by moving object
If the overall height of the power battery is reduced to save running energy, then energy efficiency improves, but the passability and comfort of the vehicle may be affected
Solution Approach 1:
The bracket's fixing portions are designed with inclined structures at predetermined angles rather than purely vertical extensions. This angular arrangement allows the connectors to be positioned effectively while reducing the vertical height requirement, distributing the structural demand across different spatial dimensions.
3Reliability
If multiple connectors are fixed to the casing directly, then the electrical connection is established, but the connectors may cause short-circuit or fire accident during large impact
Solution Approach 1:
The bracket structure serves as a pre-established protective cushioning system. By fixing the connectors to the bracket rather than directly to the casing, the bracket absorbs and distributes impact forces before they can reach the connectors and cause short-circuits or fire accidents during large impacts.

AI summary
The disclosure relates to a battery pack. The battery pack comprises: a casing; a cover, which is disposed to cover the casing; a battery assembly, which is disposed within an enclosed space formed by the casing and the cover; and an end assembly, which includes a panel and two or more connectors fixed to the panel. The battery assembly is electrically connected to a device outside the enclosed space by the connectors. The panel is sealedly connected to the casing or the cover, and is fixedly connected to the casing by a bracket. In the battery pack according to the embodiment of the disclosure, the end assembly integrated with two or more connectors is fixed to the casing by the bracket, thus the weight of the connectors is borne by the bracket and the connectors are not easy to be detached.
